Abstract: A device for affixing a tubular medical accessory to a wall of a body passage is disclosed. The said device comprises a handle portion, a barrel portion and a working head portion, said barrel portion is fitted with a pushing rod displaceable along the barrel portion upon actuating the handle portion. The working head portion is fitted with a plurality of wings and levers and said wings are preloaded with a plurality of staples. Upon initial displacement of the pushing rod in a distal direction the wings are swiveled towards the medical accessory such that they abut it and stretch it together with the body passage in a radial direction. Upon still further displacement of the pushing rod the levers are swiveled and cause the staples to exit from the wings such that the staples pierce the accessory and the wall of the body passage and affix the accessory to the body passage.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Embodiments of the present invention are directed to devices, systems and methods (both in operation of the devices and systems, and methods of treatment on a mammal) for affixing a prosthesis, e.g. graft to a first end and to a second end of a vessel is described. Such embodiments include a device which may comprise a rear handle portion, a frontal working portion and an intermediate barrel portion. The working portion may be loaded with a first plurality of staples and with a second plurality of staples. The barrel portion is preferable adapted to carry the graft thereon and the device is preferably provided with a pushing rod which may be displaceable along the barrel portion so as to cause protrusion of the first and the second plurality of staples towards the first end and towards the second end of the vessel respectively.

Abstract: The present invention relates to medical techniques, more particularly, to methods and apparatus for delivery of endovasular devices, such as grafts or stent-grafts, and their oversew fixation to the walls of blood vessels in direction from inside these vessels to their outer surface. There is proposed an apparatus for delivery and oversew fixation of grafts or stent-grafts. the apparatus comprises a tubular body with an expandable working head at the free end having eight cartridges, each of them being provided by one basic and at least one standby fastener means, substantially U-shaped staples, a control mechanism, as well as first and second connecting means. The apparatus is also provided with means for positioning inside a blood vessel. Besides, there is proposed a method for delivery and fixation of a graft or stent-graft to the wall of a blood vessel, substantially the aorta, from inside the latter.

Abstract: The present invention relates to medical techniques, more particularly to methods and apparatus for delivery and double-ended fixation of vascular prosthesis—grafts or stent-grafts to blood vessel walls in direction from inside these vessels to their outer surface. The apparatus comprises a tubular body with two expandable working heads at the free end, means for securing thereon the prosthesis end. The heads have eight cartridges each, and each of these cartridges is provided with one basic and one standby fastener means, substantially U-shaped staples. A control mechanism is provided consisting of two control modules joined together. The apparatus is also provided with means for positioning inside a blood vessel. There is further proposed a method for delivery and double-ended fixation of an endovascular prosthesis to a blood vessel wall.

Abstract: A medical implantable device for deployment within a vessel of a mammal patient is disclosed. The device has at least one surface, which might come in contact with blood, said at least one surface being coated by a biocompatible anti-trombogenic coating. The anti-trombogenic coating being presented in a thermodynamic non-equilibrium labile state defined by a surface energy favorable for immobilizing of albumen thereon while preventing adhesion of thrombogenic proteins thereto.

Abstract: 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.

Abstract: 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.
