Abstract
A self-deploying catheter assembly comprises an anchoring device mounted to a tube. A distal end of the anchoring device is held in a fixed position by a releasable suture while a proximal end is freely movable between a proximal position and a distal position defined by a stop on the tube. During insertion into a body cavity, the anchor automatically maintains a low-profile state with the ends spaced apart. Once fully inserted, the anchor self converts into a high-profile state when the tube is slightly withdrawn, bringing the ends closer together. The suture is disengaged to release the distal end of the anchor in order to facilitate a low-profile state for withdrawal of the assembly.
