Abstract
A collapsible medical device and associated method for shunting selected organs and vessels, wherein the medical device is shaped from a shape memory metal fabric. The device may be used, for example, to non-surgically create a transjugular intrahepatic portosystemic shunt. The device is preferably made from a continuous tubular metal fabric and includes two outer flanges that reduce device migration and includes a central passageway between the two outer flanges. The metal fabric may be heat treated within a mold in order to substantially set a desired relaxed shape of the device. The medical device includes a fastener for attaching to the end of a guide wire or delivery catheter. The medical device having the desired relaxed shape may be collapsed and delivered through a catheter or the like for deployment in a desired channel or opening in a patient's body and is retrievable after deployment.
