Thoracic aortic stent graft deployment device
First Claim
1. A stent graft deployment device which holds a stent graft in a retained condition and is arranged to release a distal end of a stent graft before a proximal end of the stent graft, the device having a proximal stent graft end release mechanism and a distal stent graft end release mechanism associated with a deployment catheter and an arrangement to allow movement of at least part of the deployment catheter including the distal stent graft end release mechanism independent of movement of the stent graft end release mechanism.

Abstract
A stent graft deployment device adapted for release of a distal end (29) of a stent graft (25) before the proximal end (27) of the stent graft (25). The arrangement (15) allows movement of at least part of the deployment catheter (23) independently of movement of a proximal end release mechanism has a fixed handle (16) associated with a trigger wire release mechanism (6) and a sliding handle (17) to which the deployment catheter and a capsule (21) are fixed. The sliding handle (17) is mounted on the fixed handle (16) and can slide longitudinally with respect to the fixed handle (16).

15. A stent graft deployment apparatus comprising:
-
a deployment catheter having a proximal end adapted to be introduced into a patient and a distal end adapted to remain outside a patient, the distal end including a handle arrangement, the catheter having at a proximal end thereof a region adapted in use to contain a stent graft;
a sheath arrangement adapted in use to extend over and cover the region adapted to be moved with respect to the catheter to expose the region to thereby enable deployment of the stent graft;
a nose cone dilator positioned at the proximal end of the deployment catheter;
a distal retention arrangement for the stent graft at a distal end of the region and comprising a proximally facing capsule having a passageway and adapted to retain the distal end of a stent graft;
the handle arrangement including a fixed handle and a sliding handle, at least the capsule being affixed to the sliding handle, whereby movement of the sliding handle with respect to the fixed handle moves the capsule independent of movement of the nose cone dilator.

16. A stent graft deployment apparatus comprising:
-
a deployment catheter having a proximal end adapted to be introduced into a patient and a distal end adapted to remain outside a patient, the distal end including a handle arrangement;
a longitudinal lumen through the deployment catheter;
a guide wire catheter extending through the longitudinal lumen and extending proximally of the deployment catheter, the guide wire catheter having a proximal end and a distal end;
the guide wire catheter being movable longitudinally and rotationally with respect to the deployment catheter;
a nose cone dilator being attached to a proximal end of the guide wire catheter and extending proximally thereof;
a sheath arrangement adapted in use to cover at least a portion of the deployment catheter and to extend to the nose cone dilator and adapted to be moved with respect to the catheter to enable deployment of a stent graft retained on the deployment device;
a distal retention arrangement for the stent graft at a proximal end of the deployment catheter and comprising a proximally facing capsule having a passageway and adapted to retain a distal end of a stent graft; and
the handle arrangement including a fixed handle and a sliding handle, the deployment catheter and the capsule being affixed to the sliding handle, whereby movement of the sliding handle with respect to the fixed handle moves the deployment catheter and the capsule independent of movement of the nose cone dilator. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
