摘要： A stent delivery system configured to deliver a stent to a target region of a body lumen may include a catheter; a stent associated with the catheter, the stent having a first region and a second region; a balloon associated with the catheter, the balloon having a first balloon portion associated with the catheter proximate the first region of the stent and a second balloon portion associated with the catheter proximate the second region of the stent; and a sheath about the stent and the balloon, the sheath maintaining the stent in an undeployed configuration for delivery to a target region of a body lumen. The sheath may comprise a first sheath region configured to split at a first pressure thereby permitting the first region of the stent to assume a deployed configuration, a second sheath region configured to split at a second pressure thereby permitting the second region of the stent to assume a deployed configuration, the second pressure being greater than the first pressure and the first pressure being insufficient to cause the second region of the sheath to split, a split-stopping structure between the first and second sheath regions, the split-stopping structure being configured to prevent a split from propagating from the first sheath region to the second sheath region at the first pressure.

摘要： A delivery system for delivering a self-expanding medical device such as a stent. The delivery system includes a sheath profiled or shaped to reduce instances of interference between a distal edge of the sheath and a vessel or with any lesion or lesions that might be present in the vessel. The sheath is formed by modifying a cylinder of sheath material to include three portions and an initiation slit that controls the rupturing of the sheath to facilitate delivery of the medical device. The initiation slit is positioned on the delivery system with respect to a configuration of a balloon portion of the system.

摘要： A medical device delivery system provides for a two-stage withdrawal of a deflated balloon portion of a catheter and the remains of a ruptured sheath. The deflated balloon portion is withdrawn from within an expanded medical device a predetermined distance before the remains of the ruptured sheath begins being removed from between the expanded device and a vessel wall. Initiating removal of the deflated balloon portion before the sheath reduces a total amount of drag that is exerted against a self-expanding medical device that has been deployed in a vessel.

摘要： A device for implantation in a vessel is provided with a geometry designed to reduce the drag experienced by the device when deployed using a sheathed delivery system. Sections of the device are provided with regions of high-points and low-points on the device's outer surface by curving one or more of the struts of the device. The high points serve as the contact points of the device with the sheath as the sheath and the delivery system are withdrawn from between the device and the vessel.

摘要： A medical device delivery system includes a self-expanding medical device mounted on a balloon portion of a catheter. A sheath is provided around the medical device to hold the device in place with the device staying in a compressed state. A series of perforations or an initial cut is provided in the sheath at a predetermined location, or within a predetermined range of locations, on the circumference of the sheath. The predetermined location or range of locations are determined with respect to the folds of the balloon portion.
