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.

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.
