LASER ABLATED ELASTOMER SHEATH PROFILES TO ENABLE STENT SECUREMENT

摘要

The stent placement dilation balloon assembly comprises a catheter having a distal end, a distal end portion, and a proximal end, a balloon (14) mounted to, about, and around the distal end portion of the catheter. The assembly- further includes an elastic sheath (28) positioned about and around the balloon. The outer surface of the sheath includes a profile which encourages stent securement. A stent is mounted on the sleeve for placement in a vessel in a human body.
