Variable speed self-expanding stent delivery system and luer locking connector

摘要

A stent delivery system that includes an inner member and an outer retractable sheath is operated by a handle that permits retraction of the sheath at more than one speed. The sheath may be retracted in small, incremental steps or in a single, more rapid stroke. The stent delivery system may include releasably locking of the inner member and outer sheath in a fixed position and also may facilitate admission of liquid into the device.
