|20140324149||Delivery System With Profiled Sheath Having Balloon-Oriented Position - 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.||10-30-2014|
|20130226279||SYSTEMS AND METHODS FOR DELIVERING A STENT TO A BODY LUMEN - 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.||08-29-2013|
|20090259286||Sheath With Radio-Opaque Markers For Identifying Split Propagation - 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. The balloon portion is inflated to cause the sheath to rupture and release the self-expanding medical device. A number of radio-opaque markers in a pattern that will aid in determining whether or not the sheath has properly ruptured upon inflation of the balloon portion are provided on the sheath. The radio-opaque markers are positioned with respect to an expected sheath rupture propagation path along which the sheath is expected to rupture. The pattern of the markers changes as the sheath ruptures and this change is detected by an operator of the system.||10-15-2009|
