  • Patent number: 8042720
    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.

  • Patent number: 7694866
    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.

  • Patent number: 7678124
    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.

  • Patent number: 7651498
    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.

  • Publication number: 20090240262
    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.
