Abstract

A delivery device for delivering an implantable endoprosthesis with an occlusion region for occluding fluid flow to a desired location in a body lumen. The delivery device includes an outer sleeve and an inner tube terminating at a distal tip. The distal tip is made of one of a dissolvable, bioabsorbable, or deformable material. Upon deployment of the endoprosthesis at the desired location, the shape of the distal tip is altered to a different shape and withdrawn through the constricted region of the endoprosthesis.

Claims

1. A delivery system comprising:

a tubular body including a proximal end, distal portion, a distal end on the distal portion; and

a length between the distal end and the proximal end,

a distal tip disposed on the distal portion of the tubular body, the distal tip including at least a partially bioabsorbable or dissolvable material, the distal tip adapted to be disposed in a body lumen and adapted to at least partially bioabsorb or dissolve in vivo.
