Abstract
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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
65 words
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.
Claim 2
Independent Claim
65 words
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.
Claim 3
Dependent Claim
29 words
The method of claim 1 including the additional steps of moving the wings radially inwardly after the prosthesis has been deployed, and removing the support from the body passageway.
Claim 4
Dependent Claim
23 words
The method of claim 1 wherein the wings are moved radially outwardly by pulling on an elongated member mechanically linked to the wings.
Claim 5
Dependent Claim
19 words
The method of claim 1 wherein the catheter is moved over a guidewire previously inserted into the body passageway.
Claim 6
Dependent Claim
25 words
The method of claim 1 wherein the step of moving the wings radially outwardly includes the step of controllably moving the wings a predetermined amount.
Claim 7
Dependent Claim
29 words
The method of claim 1 including the additional step of permitting perfusion of fluids within the body passageway during the steps of delivering the prosthesis and moving the wings.
Claim 8
Dependent Claim
42 words
The method of claim 1 wherein the step of delivering the prosthesis to the desired location by moving the catheter through the body passageway includes steering the support through the body passageway by moving an elongated element mechanically linked to the support.
Claim 9
Independent Claim
92 words
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.
Claim 10
Independent Claim
92 words
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.
Claim 11
Dependent Claim
21 words
The method of claim 8 including the additional step of: permitting fluid flow while transmitting the radially, outwardly directed displacement force.
Claim 12
Dependent Claim
27 words
The method of claim 8 including the additional step of: recoiling the support radially inwardly to a recoiled stance less than the diameter of the body passageway.
Claim 13
Dependent Claim
19 words
The method of claim 10 wherein the step of recoiling occurs upon cessation of the outwardly directed displacement force.
Claim 14
Independent Claim
120 words
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.
Claim 15
Independent Claim
120 words
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.
Claim 16
Dependent Claim
51 words
The method as in claim 12, further comprising the step of connecting the catheter to a device which selectively tensions and pushes the elongate element prior to the transmitting steps, the device being adapted to displace said support a calibrated distance whereby said outward displacement is to a predetermined expanded stance.
