Stent Delivery Device

摘要

A delivery device and method for use, the delivery device including a stent device, a restraining sheath, and a pull member. The restraining sheath is mounted coaxially over the stent device for maintaining the stent device in a delivery configuration, and may include a line of weakness extending axially. The pull member is to be pulled so as to split the restraining sheath at the line of weakness and withdraw the restraining sheath from over the stent device. The pull member and the line of weakness may be located on opposing sides of the restraining sheath. The pull member may have an inner part extending inside of the restraining sheath, an outer part extending outside of the restraining sheath, and a wraparound portion there between for wrapping around an axial end of the restraining sheath to radially capture the restraining sheath between the inner and outer parts.
