23 october 2017 - The present invention relates a multilayer flexible element, preferably made of wood, and related production process by laser engraving and/or cutting. More exactly, the production process consists in the processing of materials, in which a material previously rigid after the processing acquires characteristics and properties typical of a tissue, in such a way to be suitable as raw material, preferably in clothing, furnishing and design. The production process is based on the use of a laser device able to realize a pattern of grooves on the top layer of a multilayer material that, after the processing, can be used in the same way of a flexible material.
In the state of the art procedures have already been developed to make products
made of wood or other rigid material appropriately worked to create a flexible structure
that can adapt to various shapes and profiles, so that the above-mentioned products
can be used as clothing accessories or furnishing. In some cases, these structures
are real clothes. The technique used up to now consists in realizing a basic structure
articulated, for example a metallic structure with some pins that allow the rotation of a
part on the other, within this metallic structure are inserted wooden dowels to form a
mosaic. The procedure provides for the cut of the single dowels, and the subsequent
manual installation, one at a time, up to form the final product. This processing
determines a problem of precision, for the fact that intervenes an operator to realize
the product, and there is also a problem of timing, because the processing must follow
a manual operation. There is also a problem of costs because to realize a single
product you employ a certain quantity of raw material, a certain time to design the
product and manufacture it manually, and also you need labor which must intervene
All the above disadvantages are overcome by the present invention which has as main objective to make usable the same way of a tissue or other flexible material, those materials (preferably wood, but also laminates, aluminum, etc..) which by their nature and characteristics have a rigid structure and limited modeling.
A further objective is that such materials, adequately processed, can be used in the applications already in use both for tissues that for the leather.
Another objective is to use these materials (wood, laminates, plexiglas, aluminum, copper, etc..) in order to enrich the range of materials already usable in clothing and design, particularly in textiles and tanneries.
A further objective is that the mode of processing ensures high speed and precision. Another objective is that this processing technique is extremely versatile in such a way you can operate in different sectors, from clothing to furnishings, up to the automotive industry.
A further objective is that this processing is without direct contact with the material, so as to provide the maximum safety for the operator. Another objective is that the laser engraving and/or cutting should be permanent, unalterable and unchangeable.

18 august 2017 - The present invention regards a device that can be properly used for training of golf players, and more in particular in order to train the swing, that is a specific movement that is achieved when the ball is hit and launched towards a target, making the same ball to lift up from ground.
As known, in order to practice the swing, the player puts his body in front of
the ball, he takes the club using both his hands, and brings the club behind his head,
making his shoulders and back to rotate. From a position having the club on the top,
he starts the way down to the ball, by a rotary motion towards the objective of
reaching and hit the ball. At the time of contact with the ball, the motion of the hip and
the rest of the body continues. When the club and the arms point to the target, the
head starts to turn. At the time that the ball has been hit and launched in the air, the
last step of the swing starts: the hip completes the rotation, the arms move in angle
and the body results to be directed to the target, with the club touching the back
behind the neck.
Therefore, the main objective of the present invention is to propose a device for training the swing, addressed to golf players, giving the support of a fixed point to the head, so that the player can become comfortable with the movements, rotating the bust and keeping the head fixed until the time of the contact with the ball has reached.
The system is able to detect the angle of rotation of the player's bust in respect to the front direction, and able to provide a start signal for the execution of the swing, by an acoustic or visual signal, or by a graphic message on a video screen.
The system is able to detect the dynamics of the club's motion and, at the moment of touch with the ball, to detect the exact position of the club's end, the player's head and feet, so that it can be recognized if the swing has been executed correctly or not.
The system of the inventio can be integrated in more complex systems for simulation of the golf game that use the computer graphics projected on maxi-screens, in order to reconstruct some virtual fields of golf, and that the device uses the data detected in the swing in order to define the drive, direction, speed and effect given to the ball.

The present invention regards a device for brushing the teeth, having a head
composed of multiple brushes, preferably two lateral brushes and a upper brush. In
particular, the invention comprises a mechanism that permits the rotation of the
brushes and their simultaneous vertical oscillation, so that it is possible, in example, to
brush the incisor, canine, premolar and molar teeth, reaching if necessary either the
part under the cementoenamel junction.
As known, in the present state of the art, there are many models of electric
brushes, from that available commonly on the market, to the more advanced used in
the dentist's treatment room.
The idea on which the present invention is based is to increase the level of effectiveness in the operations of cleaning of teeth, by placing a certain number of brushes on more sides, and by giving them a motion that, other than rotary friction on the surface of teeth is also oscillating vertically, that means perpendicular to the longitudinal rotary axis and simultaneously parallel to the long axis of teeth, and not perpendicular as in the common electrical toothbrushes. In such a way it is possible to reach the part of teeth under the cementoenamel junction, usually hard to be reached by normal toothbrushes.
The present invention overcomes all the drawbacks of the prior art by proposing as a main objective to describe a device having multiple brushes with a rotary motion and/or oscillating motion perpendicular to the axis of rotation and parallel to the axis of tooth, in order to achieve the cleaning of teeth simultaneously on more sides, by friction of their surface. The brushes are activated by engines of electrical, mechanical or hydraulic type, and a mechanism is included converting the rotary motion in respect to the longitudinal axis to a vertical oscillating motion. In particular, both the right lateral brush and the left lateral brush have simultaneously a rotary motion in respect to the longitudinal axis and a vertical oscillating motion perpendicular to their longitudinal axis.

30 august 2017 - The present invention relates to an improved device for conversion of mechanical energy from sea waves to electric energy, that includes a float moved by sea waves, where the resulting displacement of the same float is given by the superposition of the horizontal (sway), vertical (heave) and rotational (roll) displacements, and that transmits some wave actions to some rigid rods, or to some cables, that are anchored through hinges to the sea bed. The rods are connected to respective ballasts and to a transmission shaft of an electric generator, by using cables or chains. The rotary oscillating motion of the rods is used to put the transmission shaft of the electric generator.
The main objective of the present invention is to propose an improvement in the device
for conversion of mechanical energy from sea waves to electric energy
disclosed in the Italian patent IT 1413116, by introducing an improvement in the
connection structure of float cables, and in the position of generator transmission
gears. The float connection structure and a different position of generator allow to
increase the roll of the float (the rotary motion with reference to its center of mass), in
respect to the heave (vertical) and to the sway (horizontal) oscillations, increasing the
general efficiency of the total extracted energy in the device.
The position of the transmission shaft and the position of the generator is better, from an economical point of view, due to three reasons. The first is that the number of mechanical transmission gears and generators is decreased, and therefore a decrease of costs in construction and maintainance are achieved. The second is that the mechanical stress in the structure is decreased, and it is not of bending type but it is of axial type, more exacly of traction type, therefore cheaper rods can be used, or they can be changed with cables or ropes that are significantly cheaper than rods. The third is that it is possible to achieve a rotational speed in the generator transmission shaft that is higher in respect to that having a configuration where the generator is placed at the hinges; that achieves a simpler, cheaper and more efficient multiplier of revolutions per minute, that are necessary to make the electrical generator to work properly.
Another objective is that the same device has a stable equilibrium point, and that the horizontal or vertical or rotational oscillations in respect to the same point make it possible to activate an electrical generator.
Another further objective is that the same device should be installed off-shore in respect to deep water or to shallow water.
A furter objective is that the same device should be part of a modular system that permits to produce a quantity of energy that is proportional to the amount of used sea surface, and proportional to the number of installed modules.
Another further objective is that, when the main direction of sea waves changes, the same device should adapt its orientation automatically without installing any additional add-ons.

22 august 2017 - The present invention is related essentially to a surgical system including a catheter with balloon and needle, some guiding wires and a vascular stent properly shaped. The system permits to achieve, working through endovascular ways only, a by-pass connecting vascular segments that are not functionally contiguous. In such a way the blood can overcome an obstruction that is occurred inside a blood vessel.
As known, the aortocoronary by-pass has always been considered a solution
in the treatment of the three-vessels coronary diseases (that is when all the three
coronary branches are involved), either in case of serious or mild diseases. That
happens although in recent years the stents technology, and especially the drug
eluting stents technology, has increased significantly the safety and the effectiveness
of these devices in the treatment of the atherosclerotic coronary disease. With
reference to that, also the most recent clinic trials that compare the two techniques of
revascularization have demonstrated as the aortocoronary by-pass results to be
significantly better, with reference either to decrease of mortality and to decrease of
the risk of heart attack, yet after five years since the treatment with increase of the
benefit according to the passing of time.
It is widely demonstrated that, the significant advantage of the traditional surgery, in respect to the endovascular techniques, arises especially from the use of the internal mammary artery (IMA) as the vessel chosen for the revascularization of the left anterior descending artery (LAD). Indeed, the IMA presents a low risk of obstruction and atherosclerosis due to the local characteristics keeping an open flow in the long term, even compared to the vessel grafts (SVG). That achieves a good flow of oxygenated blood in the area of distribution of the anterior descending artery (LAD), with significant perfusion pressures, even in case of serious disease in the receiving vessel. It is commonly observed that, in case of very serious events of atherosclerotic burden, the levels of coronary reserve are significantly higher when an arterious graft is installed in the internal mammary artery.
Recently, a trial using computed tomography to detect the anatomic shapes of the thoracic vascular structures has permitted to evaluate how the left internal mammary artery (LIMA) is very close to the anterior descending artery (LDA). Indeed, in all the analyzed patients there is a point in the chest where the two arteries cross by, being separated by just few millimeters of serous tissue. Furthermore, since the beginning of the past century it is well know the presence of natural by-passes connecting the internal mammary artery to the coronary artery through the pericardiacophrenic branch. The presence of these anastomosis has been indeed the rational of the surgical connection of the IMA before the introduction of the aortocoronary by-pass. Recently, a research has shown that in large part of patients it is possible to recruit functioning connections between the left internal mammary artery (LIMA) and the LAD, and between the right internal mammary artery (RIMA) and the right coronary (RC).
The proposed method, disclosed by the present invention, permits to achieve a by-pass between the left internal mammary artery (LIMA) and the LAD, and between the right internal mammary artery (RIMA) and the right coronary (RC), using a technique that is exclusively endoscopic, taking advantage of the close distance of the two respective vascular structures. The same technique can be used in order to achieve other by-passes in other vascular segments either.
The present endovascular technique permits the revascularization with the internal mammary artery even in persons that are now excluded from the traditional surgery, and opens new opportunities to the endovascular surgery. That decreases the postsurgery complications and does not require the deep sedation and the orotracheal intubation of the patient. It further permits a very fast recovery from the surgery, without the requirement to monitor the patient in a post-surgery intensive care unit. The absence of a deep anaesthesia further increases the number of treatable patients: big obese persons, patients affected by chronic respiratory failure or degenerative diseases like Alzheimer, or very old persons.

The present invention regards a medical device that is represented by a temporary
venous transfemoral or trans-saphena endoprosthesis for a total vascular exclusion of
This device results to be particularly adapt to be used in most critical surgical operations involving this organ, like in example in major hepatectomy and in hepatic trauma with caval upper hepatic venous damage.
In fact, the endoprosthesis represents an internal and temporary endovenous bypass
that permits the normal function of the caval vein to return the blood to heart, and at
the same time permits, with a simultaneous Pringle maneuver, the total vascular
exclusion of the hepatic parenchyma.
The liver receives blood coming from the portal vein and from the hepatic vein, and returns filtered blood to the caval system through the three upper hepatic veins. The vascular exclusion of the liver, according to the invention, consists in stopping the blood entering the liver, by blocking the hepatic peduncle (hepatic artery, common bile duct and portal vein) with a clamp or a tourniquet, and stopping simultaneously the way out, in such a way that the blood cannot enter the liver from the inferior caval vein through the upper hepatic veins.
Therefore, it is used the Pringle maneuver, that is well known from the current surgical techniques, in order to stop the way of the blood to the liver, and it is blocked the way out of the liver closing the upper hepatic veins, by intervention directly on the caval vein, from the inside. This blocking of the way out is achieved by installation of an endoprosthesis, that is inserted directly from the femoral vein or saphena and then it is pushed inside the inferior caval vein, reaching with the distal part the caval lower and upper hepatic tract, blocking therefore with the lateral walls the holes connecting the upper hepatic veins to the caval vein.
The endoprosthesis is composed of a main part having a cylindrical shape extending longitudinally. The part that, once it has been pushed in the caval vein, is placed close to the distal part of a inner guide, opens a spiral shaped self-expandable thin sheet, in order to bond steadily to the inside wall of the caval vein. The expansion saves an inner caval space that is necessary to keep the flow of blood inside, so that the function of blood return to heart is saved.
