A method and device for repairing incompetent venous valves and more specifically relates to repair method and an implantable support device&#x2014;extravenous corrector (), which is positionable about a dilated veins of the Sapheno-Femoral Junction (SFJ) () with the aim to apply an external compression force on the insufficient veins of SFJ and especially in the area of the venous valves. There are proposed several embodiments of a extravenous corrector for external correction of insufficient valves in venous junctions. The corrector is adapted to be placed immediately around the junction with venous valves, in abutting contact with its external area. The extravenous corrector comprises a central support member () and at least three band lengths (), connected to the member, adapted for placement around at least two veins of the venous junction in area of location of their insufficient valves, these band lengths possessing different rigidity and compressing force in direction from their proximal end to the distal end.

Method and extravenous corrector for simultaneous repair of multiple incompetent valves

Medical methods and apparatus for locating and securing intravascular devices, substantially grafts or stents-grafts, via a laparoscopic duct created by a surgical procedure to approach a blood vessel lumen. A stapler including a tubular body having at its distal end a head with a die and die lid and at is proximal end a control mechanism with a retaining handle and a control lever pivotally thereto. The lever is operatively connected via a spring-loaded pressure rod with a fastener located in the die. The movement of lever is transformed into radial forces necessary for punching through the wall of the intravascular device and the surrounding blood vessel wall with a fastener and simultaneously bending ends of the fastener apart. Securing the ends of the intravascular device to the wall of a blood vessel is performed via a set of at least two staplers, each having several simultaneously deliverable fasteners.

Method and apparatus for laparoscopic aortic repair by intravascular devices

The present invention rerlates to medical techniques, in particular, to methods and apparatus applied in minimally invasive vascular surgery to eliminate occlusion of blood vessel, using grafts and to prevent rupture of abdominal aorta using grafts or stent-grafts. More particularly, the present invention relates to methods and apparatus for locating and securing intravascular devices, substantially grafts, through a duct specially created by the surgeon to approach the blood vessel lumen. There is suggested a new and improved method for fixating an intravascular device to a blood vessel wall in combination with a new and improved stapler design based on this method. The stapler comprises a hollow body at the proximal end whereof there are mounted a guiding head and a die, and at the distal end, at a certain angle to the latter, a holding handle and a control lever, pivotally connected to this handle, and this control lever is operatively connected, via a movable pressure member, to a tip located inside the body, head and die. In the die there are disposed fastener means. The movement of control lever is converted into radial forces necessary for punching the wall of an intravascular device and surrounding blood vessel wall, location and fixation of fastener means, with simaltaneous bending of their ends. For maximum sinking of heads of fastening elements in the wall of an intravascular device, additional pushing members are movably mounted in radial slots of the die. The intravascular device, substantially graft, is fixated to a blood vessel wall, substantially aorta, via a set of at lest two staplers, and in each of the staplers there are disposed simultaneously several fastener means.
