MEDICAL DEVICE DELIVERY SYSTEM WITH SHEATH HAVING BALLOON-RELATIVE POSITION |
摘要 |
A delivery system for delivering a self- expanding medical device such as a stent (16) includes the stent mounted on a balloon portion (30) of a catheter. A sheath (18, 40) is provided around the stent to hold the device in place in a compressed state. A portion of the sheath (42, 44) is positioned 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 a configuration of the balloon portion. The sheath may be 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 (602) that controls the rupturing of the sheath to facilitate delivery of the medical device. |
