First Claim
Patent Images
1. A device for delivering a prosthesis percutaneously, comprising:
- at least one coupling mechanism including;
a first member;
a second member having an aperture;
a control mechanism useable to rotate a distal end of one of said members away from the other from a closed position to an open position;
a locking-pin attached to said first member;
wherein said locking pin extends into said aperture in said closed position and is spaced apart from said aperture in said open position.

Abstract
An expandable delivery tool for aiding the deployment of a prosthesis device within a patient. The delivery tool has a generally elongated shape with a selectively expandable distal end region that flares outward in diameter. Once advanced percutaneously within a patient'"'"'s vessel, the delivery device can help locate a target area, assist in deploying a prosthesis at a desired position and further expand the prosthesis after deployment.

6. A method of percutaneously delivering a prosthesis comprising:
-
advancing a distal end of a delivery tool near a target location within a patient; increasing a diameter of said distal end of said delivery tool; deploying a prosthesis at said target location, adjacent to said distal end of said delivery tool; and preventing said prosthesis from advancing past said diameter of said distal end of said delivery tool. - View Dependent Claims (7, 8, 9, 10)

11. A device for delivering a prosthesis within a vascular system, comprising:
-
an elongated outer sheath having a lumen disposed therethrough; a control wire disposed within said lumen; and a mesh member having a first configuration with a first diameter and a second configuration with a second diameter, said second diameter being larger than said first diameter; wherein relative movement of said control wire relative to said elongated outer sheath deforms said mesh member between said first configuration and said second configuration. - View Dependent Claims (12, 13, 14, 15)

16. A device for delivering a prosthesis within a vascular system, comprising:
-
an elongated outer sheath having a lumen disposed therethrough; a control wire disposed within said lumen; and an expandable region having a plurality of arms;
said expandable region having a first configuration with a first diameter and a second configuration with a second diameter, said second diameter being larger than said first diameter;wherein relative movement of said control wire relative to said elongated outer sheath expands or contracts said expandable region between said first configuration and said second configuration. - View Dependent Claims (17, 18, 19, 20)

21. A device for delivering a prosthesis within a vascular system, comprising:
-
an elongated outer sheath having a lumen disposed therethrough; a plurality of balloons disposed on a distal end of said outer sheath and in communication with said lumen;
said plurality of balloons having a first configuration with a first diameter and a second configuration with a second diameter, said second diameter being larger than said first diameter;wherein delivery of an inflation medium through said lumen expands or contracts said plurality of balloons between said first configuration and said second configuration.
