Abstract
A pusher assembly for a delivery system for a self-expanding stent () which is delivered by proximal withdrawal of a sheath () radially surrounding the stent has a stent pusher element () which defines a lumen for a guidewire (), a pusher strand () that extends to the proximal end of the delivery system and bears an end-wise compressive stress during release of the stent. A transfer shaft () links the distal end of the pusher strand () to the pusher element () and lies side-by-side with the guidewire (). In a rapid exchange version, an adapter () provides two lumens side-by-side, one () carrying the pusher strand () and the other () defining a proximal guidewire part. To the adapter is mounted the proximal end of the stent sheath (). The system allows modular () construction, a tapered tip (A) on the sheath, and an uncluttered internal configuration which facilitates passage of pulses (F) of liquids from the proximal to the distal end of the system.
