STENT DELIVERY AND DEPLOYMENT SYSTEM

摘要

A delivery system for delivery and deployment of a self expanding stent (1) especially in an arterial vessel with a tortuous passageway leading thereto comprises a catheter shaft (9) with a distal sheath (6). An inner core (5) is fixed to a larger diameter outer core (10), the difference in diameter providing an abutment. To deploy the stent (1), the sheath (6) is drawn proximally relative to the inner core (5), the proximal end of the scent (1) is engaged by the abutment and the stent (1) expands as it is uncovered by the sheath (6). The system includes a stabiliser tube (25) to which the inner core (5) is fixed, at least during the deployment of the scent (1).
