Abstract

A medical device delivery system, having a rolling retractable sheath covering a medical device mounting region on the system is disclosed. The rolling retractable sheath comprises an inner wall and an outer wall and may be formed of one or more materials, optionally porous. Optionally, a lubricant may be applied selectively to the interior and exterior walls of the stent.

Claims
