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

36. A, method for intraluminally delivering a distensible stent comprising:
-
providing a radially distensible, self-expanding stent having a proximal and a distal end releasably disposed on a catheter;
said catheter comprising;a first elongate tubular member having a proximal end and a distal end; a band circumferentially disposed over at least a portion of said first tubular member at said proximal end, said band having at least one projection for releasably engaging a portion of said proximal end of said stent; and a second elongate tubular member slidably disposed over said first tubular member, said band and said stent; wherein said stent is releasably disposed between said tubular members; positioning said catheter within a bodily lumen; slidably retracting said second tubular member from said first tubular member to uncover portions of said stent, whereby the uncovered portions of said stent radially expand against a wall of the bodily lumen; and slidably retracting said second tubular member from said band to release said proximal end of said stent from said band. - View Dependent Claims (41)

37. A method for repositioning a radially distensible stent within a bodily lumen comprising:
-
providing a radially distensible, self-expanding stent having a proximal and a distal end releasably disposed on a catheter;
said catheter comprising;a first elongate tubular member having a proximal end and a distal end; a band circumferentially disposed over at least a portion of said first tubular member at said proximal end, said band having at least one projection for releasably engaging a portion of said proximal end of said stent; and a second elongate tubular member slidably disposed over said first tubular member, said band and said stent; wherein said stent is releasably disposed between said tubular members; positioning said catheter within a bodily lumen to a first position; slidably retracting said second tubular member from said first tubular member to uncover only a portion of said stent, whereby the uncovered portion of said stent may radially expand against a wall of the bodily lumen; slidably extending said second tubular member over said first tubular member to recover said a portion of said stent; and repositioning said catheter within a bodily lumen from said first position to a second position. - View Dependent Claims (38, 42)
