    摘要： When a main stent-graft is placed in a vessel of a patient and a branch vessel is blocked by the main stent-graft, a RF plasma catheter is used to cut out a portion of the graft cloth of the main-stent graft adjacent to an ostium of the branch vessel to be perfused. To ameliorate possible adverse effects associated with the use of the RF plasma catheter, e.g., creation of coagulum, (desiccated, coagulated blood) or perhaps a cut stent strut, a special process using saline flushing, a novel RF plasma catheter with an insulated tip, or a combination of the two is used.

    摘要： A tubular prosthesis comprises a tubular graft; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of the apexes, and a second end defined at least in part by a second group of the apexes, the first group of apexes being pivotally attached to the tubular graft so as to form a plurality of circumferentially arranged hinges about which the stent can pivot so that the second group of apexes can move between a position where they are inside the tubular graft and a position where they are outside the tubular graft. In one embodiment a tubular prosthesis comprises a tubular graft having a first end margin, a second end margin and a central portion therebetween; and an undulating stent having a plurality of apexes, a first end defined at least in part by a first group of the apexes, and a second end defined at least in part by a second group of the apexes, the undulating stent being secured to the tubular graft in a manner such that it can be inverted to extend generally in the same direction as the tubular graft with one end thereof forming an end of said tubular prosthesis and pointing away from the central portion of the tubular graft.

    摘要： A primary and branch graft deployment delivery system (70) comprises a primary graft (72) having a branch port opening or member (75), a retractable primary sheath containing the primary graft, an outer tube (60) within the retractable primary sheath and within the primary graft, an inner tube (61) within the outer tube, a cap (54 or 71) coupled to the inner tube and configured to retain at least a portion of a proximal area (73) of the primary graft in a radially compressed configuration. The system further comprises a branch graft (89) advanceable through the branch graft port member and further comprising a snap connector member (90) associated with the branch graft, the snap connector member being configured to frictionally engage the port member, the engagement of the snap connector to the port member forms a connection between the proximal end of the branch graft and the primary graft.

    摘要： An endostapler delivery system includes a biasing mechanism to offset or counter forces generated by a stapling device and therefore prevent the stapling device from moving during the firing of the staple. The delivery system includes a catheter having at least one lumen extending there through for receiving the stapling device. The biasing mechanism is an expandable biasing cage having a dome or semi-circular expanded shape provided at the distal portion of the catheter. When expanded, the biasing cage does not block or occlude a vessel, thereby allowing blood flow to continue during the stapling procedure. The endostapler delivery system further includes a steering wire that can be used to bend the catheter shaft.
