Abstract

A system and method for deploying an occluding device that can be used to remodel an aneurysm within the vessel by, for example, neck reconstruction or balloon remodeling. The system comprises an introducer sheath and an assembly for carrying the occluding device. The assembly includes an elongated flexible member having an occluding device retaining member for receiving a first end of the occluding device, a proximally positioned retaining member for engaging a second end of the occluding device and a support surrounding a portion of the elongated flexible member over which the occluding device can be positioned.

Claims

1. A method for introducing and deploying an occluding device within a vessel, said method comprising:

introducing an elongated sheath including an introducer sheath with a guidewire assembly into a catheter;

advancing said guidewire assembly out of said sheath and into said catheter;

positioning an end of said catheter proximate an aneurysm;

advancing at least a portion of said guidewire assembly out of said catheter;

rotating a portion of said guidewire assembly while deploying said occluding device at the aneurysm.

2. The method according to claim 1 further comprising the step of removing the guidewire assembly from within the catheter.

3. The method according to claim 1 further comprising the step of removing the catheter from within the vessel.

4. The method according to claim 1 further comprising the step of confirming the position of said occluding device prior to deploying said occluding device.

5. The method according to claim 1 further comprising the step of creating friction between an inner surface of said catheter and said occluding device when deploying said occluding device.

6. The method according to claim 1 wherein said step of rotating said guidewire assembly includes the step of separating said occluding device from an end of a retaining member.
