Abstract

A method of deploying a prosthesis includes engaging a hub assembly (702) of a handle (112) to a threaded outer surface of a slide shaft (402) of the handle; rotating the hub assembly to cause axial translation of the hub assembly and a sheath (106) coupled to the hub assembly to initiate deployment of the prosthesis (102); disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth (708A, 708B, 1804A, 1804B) of the hub assembly out of threaded engagement with the threaded outer surface; and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.

Claims

AMENDED CLAIMS [received by the International Bureau on 18 July 2005 (18.07.2005); original claims 1 , 3-5, 14 amended; original claim 2 canceled ; remaining claims unchanged (4pages)]
1. Λ delivery system comprising: a sheath; and a handle comprising: a slide shaft comprising a threaded outer surface; and a hub assembly coupled to said sheath, said hub assembly comprising an internal slider subasscmbly for selectively engaging and disengaging said hub assembly with said threaded outer surface, wherein said internal slider subasscmbly comprises a thread tooth comprising a protruding tooth, said thread tooth being pivoted to engage and disengage said hub assembly with said threaded outer surface.
2. Canceled (without prejudice).
3. The delivery system of Claim 1 wherein said protruding tooth is thrcadedly engaged with said threaded outer surface when said hub assembly is engaged with said threaded outer surface.
4. The delivery system of Claim 1 wherein said protruding tooth is spaced apart from said threaded outer surface when said hub assembly is disengaged from said threaded outer surface.
5. 1 he delivery system of Claim 1 wherein said internal slider subasscmbly comprises an inticr slider comprising a thread tooth pivot support, said thread tooth being pivotal ly mounted ou said thread tooth pivot support.
6. The delivery system of Claim 5 wherein said thread tooth pivot support comprises a protruding pivot pin seated in a pivot aperture of said thread tooth.
7. The delivery system of Claim 5 wherein said inner slider further comprises a distal thread tooth pivot aperture and a proximal thread tooth pivot aperture, said thread tooth pivot support being between and separating said distal thread tooth pivot aperture and said pro imal thread tooth pivot aperture.
AMENDED SHEET (ARTICLE 19) 26
