1. A deployment system for deploying a prosthesis in a duct, comprising:
- an elongate core cylinder for delivering a prosthesis to a predetermined location in a duct;
a prosthesis surrounding the core cylinder;
a sheath surrounding the prosthesis;
a handle for deploying the prosthesis, the handle comprising;
a base member connected to the core cylinder, the base member having an elongate axis and defining a shaped opening having the general shape of a rectangular wave wherein some portions of the opening extend generally parallel to the axis of the base member, and some portions extend generally perpendicular to the axis of the base member;
a slide member operably attached to the sheath, the slide member being moveable in relation to the base member, whereby, when the slide member is moved in relation to the base member, the sheath is moved in relation to the prosthesis;
a protrusion on the slide member extending through the shaped opening;
a biasing member positioned to urge the slide member in relation to the base member;
whereby, repeated manual movement of the protrusion along those portions of the opening extending perpendicular to the base member'"'"'s axis causes the biasing member to incrementally retract the sheath from the prosthesis.

Abstract
A system for controlled deployment of a prosthesis, in which a sheath is retracted from a prosthesis in a body vessel or duct. The system includes a handle for deploying the prosthesis, the handle comprises a base member fixed to a catheter, and a slide member for sliding past the base member, the slide member being attached to an end of a retraction member. The base member includes an opening having the general shape of a rectangular wave for interacting with the slide member, whereby, repeated manipulation of the slide member causes the sheath to be retracted.

16. A method of retracting a sheath to uncover a prosthesis mounted on a catheter, comprising:
-
attaching the catheter to a base member having a first elongate axis, the base member being positioned proximal to the catheter; operably attaching the sheath to a slide member having a second elongate axis, the slide member being slidable parallel to the first axis, biasing the slide member proximally in relation to the base member; incrementally moving the slide member proximally in relation to the base member by rotating the slide member about the second axis, whereby the sheath is incrementally retracted proximally to uncover the prosthesis. - View Dependent Claims (17, 18, 19, 20, 21)
