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 biasing cage may include a plurality of ribbons or strands that extend generally parallel to the blood flow when expanded in situ, a mesh or braided structure, or a plurality of ribbons or strands that extend generally parallel to the blood flow when expanded in situ and a mesh or braided structure placed over the plurality of ribbons.

摘要： A prosthesis delivery system comprises a tip having a lumen, a first end and a second end; a sleeve coupled to the tip second end; a spindle comprising a spindle body and a plurality of projections extending radially outward from the spindle body, each projection having a first edge and a second edge, the first edge facing the tip and the second edge extending from the first edge, being angled toward the tip first end, and extending toward the sleeve; and endoprosthesis having an undulating spring with a plurality of crown portions having apices, where the crown portions extend over at least one of the first or second edges and the sleeve radially constrains the apices.
