RECONSTRAINMENT BAND WITH REDUCED REMOVAL INTERFERENCE

摘要

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.

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 two opposing obtusely shaped surfaces angled relative to the longitudinal axis, each obtusely shaped surface having rounded edges and facing one of said ends, said fin comprising an exterior surface that extends longitudinally between said two opposing obtusely shaped surfaces, the exterior surface having a top face with a first longitudinal length radially spaced from the band, and a bottom face with a second longitudinal length adjacent the band, wherein the first longitudinal length is shorter than the second longitudinal length.
