Method and device for providing full protection to a stent
First Claim
1. A catheter comprising:
- a catheter shaft, at least a portion of the catheter shaft defining a medical device receiving region; and
at least one sleeve, the at least one sleeve comprising a tubular member constructed and arranged to transition between an extended state and a retracted state, the tubular member consisting of a first portion and a second portion being at least partially constructed from a shape memory material, the first portion being engaged to a portion of the catheter shaft adjacent to the medical device receiving region, in the extended state the second portion at least partially overlays the medical device receiving region of the catheter shaft, the second portion retracting away from the medical device receiving region by self-transitioning from the extended state to the retracted state of the tubular member.

Abstract
A catheter comprises a catheter shaft, at least a portion of which defines a medical device receiving region, and at least one sleeve. The at least one sleeve comprises a tubular member constructed and arranged to transition between an extended state and a retracted state. The tubular member has a first portion being engaged to a portion of the catheter shaft adjacent to the medical device receiving region. In the extended state a second portion is constructed and arranged to at least partially overlay the medical device receiving region. In the retraced state the second portion is removed from about the medical device receiving region. At least one of the first portion and the second portion of the tubular member are at least partially constructed from a shape memory material.
