An implant delivery system and method comprises an implant, for example, a stent, and a delivery catheter. The stent has a scaffold with a coating or a shell that retains the scaffold in a collapsed configuration. The coating or shell is made of a material that dissolves or biodegrades upon exposure to a dissolution or biodegradation media. The stent is used with an implant delivery system which has a catheter with a catheter, wherein the stent is mounted on the catheter shaft. The catheter shaft is configured to be withdrawn through the patient's vessel when the scaffold is in its expanded configuration. Advantageously, the implant is thereby prevented from changing length during implant delivery and implant deployment.

A balloon catheter may include a multi-lumen tube having an inflation lumen and a guide wire lumen. The multi-lumen tube may include a proximal end and a distal end and may terminate at a distal tip. The catheter may include an extension tube extending distally from the distal tip of the multi-lumen tube and a dilatation balloon disposed about the multi-lumen tube and the extension tube. The distal tip of the multi-lumen tube may be under the balloon.
