Delivery System for Preloaded Fenestrated Device

摘要

A pre-loaded stent graft delivery device having a guide wire catheter and a handle including a multi-port manifold with access ports, where an access sheath extends from each access port. A sheath is disposed coaxially around the guide wire catheter and includes two splits that enable the retraction of the sheath while the access sheaths are disposed within the respective access port of the manifold.

主权项

1. A pre-loaded stent graft delivery device comprising:
a guide wire catheter having a guide wire lumen therethrough; a handle assembly at a distal end of the guide wire catheter, the handle assembly including a manifold, where the manifold comprises two side ports and a through bore, the two side ports extending distally from the through bore; a nose cone dilator at the proximal end of the guide wire catheter; a pusher catheter extending from the manifold towards the nose cone dilator, the pusher catheter comprising at least one lumen therethrough where the guide wire catheter extends through the at least one lumen within the pusher catheter; an access sheath disposed within each of the two side ports of the manifold; and a sheath disposed coaxially over the pusher catheter, where the sheath has at least two longitudinal splits formed along a portion of the length of the sheath, where each split is aligned with each of the access sheaths such that the sheath can be at least partially retracted over the access sheaths.
