Abstract
A method of delivering a stent comprising providing an elongate guide having a stent coaxially supported on the guide for placement and movement by the guide, providing a tubular sheath member, advancing the elongate guide into the body to provide initial access to a preselected treatment site within the body and to carry and deliver the stent to position the stent at the treatment site, and exposing the stent from the tubular sheath member to enable the stent to move from a first reduced diameter position to a second expanded position.

23. A method of delivering a stent within a body comprising:
-
providing an elongate guide having a proximal end, a distal end, a length therebetween, and a radially expandable stent coaxially supported on the elongate guide for placement and movement by the elongate guide;
providing a tubular sheath member;
advancing the elongate guide into the body to provide initial access to a preselected treatment site within the body and to carry and deliver the stent to position the stent at the treatment site, the tubular sheath member covering at least part of the stent during advancement through the body; and
exposing the stent from the tubular sheath member to enable the stent to move from a first reduced diameter position to a second expanded position. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)

32. A method of delivering a stent within a hollow body organ comprising:
-
providing a stent delivery assembly including an elongate guide in the form of a wire or hypotube, a stent mounted on the elongate guide proximal of a distalmost tip of the guide, and a tubular sheath for covering a least a portion of the stent during advancement of the elongate guide through the body;
inserting the elongate guide, stent and tubular sheath into the body;
initially advancing the elongate guide into the body to provide initial access to an area of stenosis or aneurysm;
further advancing the elongate guide without passage over a guidewire to cross the stenosis or aneurysm to enable positioning of the stent at the stenosis or aneurysm, the tubular sheath covering at least part of the stent during advancement through the body; and
exposing the stent from the tubular sheath to enable the stent to move from a first reduced diameter position to a second expanded position to treat the stenosis or aneurysm. - View Dependent Claims (33, 34, 35, 36)
