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.

Claims (19)

1 . 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.

2 . The method of claim 1 , further comprising:

decreasing said diameter of said distal end of said delivery tool to a desired expanded diameter of said prosthesis; and

moving said distal end of said delivery tool through said prosthesis so as to expand said prosthesis to said desired expanded diameter.

3 . The method of claim 1 , further comprising:

decreasing said diameter of said distal end of said delivery tool;

moving said distal end of said delivery to within said prosthesis; and

increasing a diameter of said prosthesis by increasing said diameter of said distal end of said delivery tool.

4 . The method of claim 1 , wherein said increasing a diameter of said distal end of said delivery tool further comprises modifying a configuration of a mesh section of said distal end.

5 . The method of claim 1 , wherein said advancing a distal end of a delivery tool near a target location within a patient further comprises advancing said distal end of a delivery tool through a valve within a vascular system.

6 . 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.
