Reconstrainment Band with Reduced Removal Interference
First Claim
1. A reconstrainment band for use with a stent delivery device, said reconstrainment band comprising:
- a hollow generally tubular shaped band having proximal and distal ends and having an exterior surface for engaging a stent and an interior surface for engaging a delivery tube,said exterior surface having at least one fin projecting therefrom along the longitudinal axis of said band, said fin having at least one obtusely shaped surface relative to the longitudinal axis and facing one of said ends.

Abstract
The reconstrainment band includes a hollow generally tubular shaped band having proximal and distal ends and having an exterior surface for engaging a stent and an interior surface for engaging a delivery tube. The exterior surface has at least one fin projecting therefrom along the longitudinal axis of the band. The fin has at least one obtusely shaped surface relative to the longitudinal axis and facing one of the ends. The reconstrainment band is included in a delivery device for intraluminally positioning and deploying a radially distensible stent. Reconstrainment of a partially deployed stent is provided by the delivery device.

9. A delivery device for intraluminally delivering a radially distensible stent comprising:
-
a delivery tube; a reconstrainment band having a hollow generally tubular shaped band having proximal and distal ends and having an exterior surface and interior surface, the interior surface engaging the delivery tube such that the band is secured thereto, the exterior surface having at least one fin projecting therefrom along the longitudinal axis of the band, the fin having at least one obtusely shaped surface relative to the longitudinal axis and facing one of the ends; a radially distensible generally tubular shaped stent located around the band such that the fin extends into a void in the stent; and a hollow generally tubular sheath located around the stent in coaxial relation therewith, the sheath being longitudinally displaceable relative to the stent and delivery tube. - View Dependent Claims (10, 11, 12)
