First Claim
Patent Images
1. A self-expanding stent delivery system comprising:
- a sleeve for restraining a stent in a compressed form, an inner member for receipt within at least a portion of the sleeve, the inner member comprising a corewire and outer cladding, the corewire comprising a distal stent-bearing section, and the cladding covering at least a distal portion of the corewire proximal to the stent-bearing section, wherein the inner member is adapted to provide increased flexibility in a proximal to distal fashion, and has a substantially constant diameter proximal to the stent bearing section.

15. A self-expanding stent delivery system comprising:
-
a corewire comprising a constant diameter distal section upon which the stent is received and a body section proximal to the distal section, and having a cladding covering at least the proximal section, wherein the cladding has a constant outer diameter;
a filter mechanism attached to the distal section of the corewire; and
an outer sleeve set over the corewire and cladding, wherein the outer sleeve is adapted to hold stent and filter in reduced states. - View Dependent Claims (16, 17, 18, 19, 20)
