  • Publication number: 20040002715
    Abstract: A method for relining a blood vessel. A tubular liner of biocompatible material, having an anchoring device connected to a distal end thereof, is inserted into a blood vessel using a delivery system. The delivery system may include a removable hub that is initially attached to the tubular liner and a hollow tip that is positioned over the anchoring device. The tip is positioned at a predetermined location and the anchoring device is removed from the tip, contacting a wall of the blood vessel. The liner is attached to the blood vessel following separation from the hub and removal of the delivery system from the blood vessel.

  • Patent number: 6589273
    Abstract: A delivery system and device for re-lining bodily vessels. A stent is attached to a distal end of a tubular lining made of biocompatible material and loaded into a hollow atraumatic tip. A semi-rigid shaft connects the atraumatic tip to a stopper and runs through the center of the tubular lining. The proximal end of the tubular lining is attached to a sliding hub. Optionally, a balloon is positioned near the stent in fluid communication with the shaft. The assembled device is introduced into a bodily vessel following an endarterectomy or atherectomy procedure. The atraumatic tip is delivered to a predetermined location and upon reaching that destination, the stent is released from the tip to expand against the vessel wall. If a balloon is utilized, it is inflated to ensure that the stent is fully deployed within the vessel. The balloon is then deflated arid the tip and shaft are pulled through the expanded stent and tubular lining.

  • Patent number: 6312462
    Abstract: The device of the present invention comprises a bifurcated graft fabricated from expanded PTFE (ePTFE). The inventive device is double walled so that following insertion into an aneurysm, fluid can be injected between the walls to expand the device thereby opening the inner tubular graft for receiving blood flow and locking the device into place in the aorta. The injected fluid may polymerize so that the device is permanently held in its expanded form. One embodiment of the device is fabricated with pockets or channels. After the device is delivered and expanded additional stiffening struts can be inserted into these pockets. In this way the basic device can be furled and tightly compressed for delivery (something not possible with a stent containing device). After the device is expanded, a stent-like structure can be inserted endovascularly giving the strength and resiliency of a stent-containing prosthesis.
