First Claim
Patent Images
1. A device for treating a lumen of the body comprising:
- a catheter having a distal end for insertion into the lumen of the body;
a stent mounted on the distal end of the catheter, said stent characterized by a distal end, a proximal end, and a center portion, said stent being compressed in an small diameter insertion configuration; and
a fairing cap covering the distal end of the stent, said fairing cap comprising a dissolvable material, said fairing cap terminating proximally from the distal end of the stent so as to leave the center portion of the stent uncovered by the cap.

Abstract
A soluble capsule, fairing or adherent material for a stent catheter or other device to inserted into the human body. The capsule, fairing or adherent material is made of a material which dissolves within the body in a convenient time, for example ten or fifteen minutes, allowing a convenient time for placement of the device and protecting the blood vessel from any sharp surfaces of the device.
