STENT DELIVERY SYSTEM AND METHOD OF MANUFACTURING SAME
First Claim
1. A stent delivery system, comprising:
- an outer elongate shaft having a lumen;
an inner elongate shaft extending through the lumen of the outer elongate shaft;
a stent engaging sleeve surrounding a distal region of the inner elongate shaft; and
a self-expandable stent surrounding the stent engaging sleeve and positioned within the lumen of the outer elongate shaft in a compressed state, the self-expandable stent including a wire mesh;
wherein the wire mesh of the self-expandable stent is embedded into the stent engaging sleeve in the compressed state.

Abstract
Stent delivery system and method of manufacturing same. The stent delivery system comprises an inner catheter with an enlarged tip disposed at the distal end thereof. A stent engaging sleeve coaxially surrounds and is secured to a portion of the inner catheter proximally contiguous to the tip. The stent engaging sleeve is used to frictionally engage a stent mounted thereover in such a way as to prevent the stent, during deployment, from sliding proximally relative to the inner catheter. The system additionally comprises a self-expandable stent of the type comprising a knitted mesh of nitinol wire flexible in both the radial and longitudinal axes. The stent is mounted over the stent engaging sleeve in a longitudinally stretched state. The system also includes an outer catheter surrounding the stent and stent engaging sleeve, the outer catheter being adapted for axial movement relative to the inner catheter.
