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 relates to medicine, in particular, to clamps used in vascular surgery for occlusion of blood vessels during a surgical operation, such as vascular clamps used in aortic aneurysm repair. The claimed supplementary vascular clamp comprises a pair of pivoting arms, each of them having a proximal end and a distal handle end. Each pivoting arm contains clamping jaws rigidly attached to a respective proximal end of this arm and shaped as a concave semi-cylindrical or semi-oval cavity. The clamping jaws are movable between the open position and closed position and define a through cylindrical or oval cavity in their closed position. The clamping jaws of the vascular clamp are also provided with a tightening means to provide intra-aortal bending of the ends of staples of an open approach stapler. The tightening means is shaped as plates or a strip of resilient material. The strip may be provided with a tensioning device. The vascular clamp may be also provided with a compensating means for correcting non-uniformity in the thickness of aorta walls. The vascular clamp may be further provided with a compensating means for correction of irregularity in wall thickness of the aorta, a first and a second sealing means for providing secure enclosure of aorta walls, as well as a means for providing regular ejection of staples.

There is provided a sternal closure system for re-approximating the left and right halves of a patient's longitudinally incised sternum during a surgical procedure in the thoracic cavity. The system includes a first anchor, disposed inside the left half of the sternum, a second anchor, disposed inside the right half of the sternum, and a fixing element for rigid connection between the first and the second anchors, respectively disposed within the left and right halves of the sternum, facilitating separation of the left and right halves of the sternum closed in this way, in case of post-operative emergency surgical procedures. An apparatus for fixing and removing the anchors is also provided.

Sternal closure system, method and apparatus therefor

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.

A compression device for external correction of insufficient valves in venous junctions is adapted for placement around the junction. The compression device has a band encompassing at least two veins of the junction. The band has a different rigidity and compression force in a direction extending from its proximal end to its distal end. The band is formed with a main compressing portion disposed on a vein surface of the junction around an insufficient valve. Intermediate and fastening portions of the band are also disposed on the vein surfaces adjacent the main compression compressing portion. The band is preferably shaped as a Mobius band. A method for external correction of insufficient valves in venous junctions is also disclosed.
