摘要： A suturing apparatus comprises an elongated body, at least one arms movable relative to the elongated body and at least one needle movable relative to the elongated body. The arm releasably holds an end portion of a length of suture. The arm has a sharp end portion adapted to pierce an inner surface of a wall of a biological structure and pass an end portion of the suture through the inner surface. The needle is adapted to pierce the inner surface of such biological structure at a location proximal to the location where the end portion of the suture was inserted. The needle captures an end portion of the suture from the arm and draws the end portion of the suture back through the inner surface. The end of the suture is then drawn out of the biological structure by removing the elongated body.

摘要： An evacuation sheath assembly and method of reducing or removing a blockage within a vessel without permitting embolization of particulate matter is provided. The evacuation sheath assembly includes a first elongate tubular member, having proximal and distal ends and a main lumen configured to be placed in fluid communication with a blood vessel. An expandable member is provided on a distal portion of the tubular member and is configured to form a seal with the blood vessel. The evacuation assembly further includes a second elongate tubular member having proximal and distal ends and an inflation lumen configured to be placed in fluid communication with the expandable member and a gas inflator. The gas inflator includes a high pressure gas source and a mechanism for regulating the pressure of the gas delivered by the gas inflator. The gas inflator is configured to be placed in fluid communication with the proximal end of the inflation lumen in order to provide a regulated pressure gas source for inflating the expandable member. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. The expandable member is inflated to provide form a seal between the blood vessel and the guide catheter and a vacuum is applied to the main lumen of the first elongate tubular member to cause retrograde blood flow and carry fluid into the main lumen of the evacuation sheath assembly.
