Patent ID: 8062282

Claim:
A method for temporarily occluding a body opening, comprising the steps of: introducing a tip of a catheter into the body opening, the tip including a central longitudinal axis; advancing a pre-mixed thermosensitive polymer through substantially the length of a single lumen of the catheter and expelling the thermosensitive polymer from the tip of the catheter into a portion of the body opening, with at least a portion of the thermosensitive polymer being expelled from the tip in a direction generally radially outward from the central longitudinal axis to promote adherence of the thermosensitive polymer on a wall defining the body opening; at least partially withdrawing the tip from the body opening and allowing the thermosensitive polymer to harden as it warms to body temperature to form a plug in the body opening; and removing said plug by a subsequent cooling of said thermosensitive polymer wherein removing said plug comprises applying a cool liquid to said thermosensitive polymer.
