ENDOPROSTHESIS DELIVERY SYSTEM WITH STENT HOLDER

摘要

A device, such as a catheter, for intraluminally delivering a distensible stent (28) includes a first elongate tubular member (12) having a proximal end (16) and a distal end (18); a band (24) circumf erentially disposed over at least a circumferential portion of the first tubular member (12) at the proximal end (16), the band (24) having at least one projection (26) for releasably engaging a portion of a radially distensible stent (28); and a second elongate tubular member (14) slidably disposed over the first tubular member (12) and the band (24). Desirably, the at least one projection (26) is a low-profile, lobate-shaped projection. The band may include two opposed projections, where the two opposed projections may be circumf erentially disposed at about 180- from one and the other. Desirably, the band includes a metal, for example, stainless steel.
