Patent Images
1. A method for intraluminally deploying a prosthesis at a desired location within a body passageway, comprising the steps of:
- placing the prosthesis over a support comprising at least two movable wings mounted on a catheter;
delivering the prosthesis to the desired location by moving the catheter through the body passageway; and
moving the wings radially outwardly to thereby deploy the prosthesis within the body passageway.

Abstract
The invention provides a method for intraluminal delivery and deployment of an expandable prosthesis at a site within a body lumen. The method comprises the steps of placing the prosthesis over a support having at least two movable wings mounted on a catheter, delivering the prosthesis to the desired location by moving the catheter through the body passageway, and moving the wings radially outwardly to thereby deploy the prosthesis within the body passageway.

8. A method for intraluminally implanting a prosthesis mounted over a support on a catheter, the support comprising at least two movable wings, comprising the steps of:
-
delivering the prosthesis to a desired location by moving the catheter through a body passageway; transmitting a radially, outwardly directed displacement force to the support, the wings of the support being displaced radially outwardly such that the wings assume a circumferentially spaced relation to one another and that the prosthesis contacts the body passageway; implanting the prosthesis in the body passageway by sufficiently displacing the wings. - View Dependent Claims (9, 10, 11)

12. A method for intraluminally implanting a prosthesis disposed on a mechanical support on a catheter that has been inserted into a body passageway, comprising:
-
transmitting a radially, outwardly directed displacement force to the support by tensioning an elongate element, said support being displaced radially outwardly to an expanded stance such that the prosthesis contacts the body passageway; transmitting a radially, inwardly directed displacement force to the support by pushing the elongate element, said support being displaced radially inwardly to a recoiled stance less than the diameter of the body passageway while leaving the prosthesis in contact the body passageway; and permitting fluid flow while transmitting either of said radially, outwardly directed displacement force or said radially, inwardly directed displacement force. - View Dependent Claims (13)
