Abstract

A tool for deploying an expandable structure into interior body regions provides a catheter body having an interior lumen. The catheter body carries an expandable structure. A stylet is sized configured for passage through the lumen and adapted to straighten the expandable structure during deployment into an interior body region.

Claims

1. A tool for deploying an expandable structure into interior body regions, the tool comprising

a catheter body defining an interior lumen,

an expandable structure having a distal end and carried by the catheter body, and

a stylet having a proximal end and being sized and configured for passage through the lumen and adapted to straighten the expandable structure during deployment into an interior body region.

2. A tool as in claim 1

wherein the stylet is substantially rigid.

3. A tool as in claim 1

wherein the stylet is made of stainless steel.

4. A tool as in claim 1

wherein, after passage of the stylet through the lumen, the proximal end of the stylet is coupleable to the catheter body.

5. A tool as in claim 1

wherein, after passage of the stylet through the lumen, the stylet abuts against the distal end of the expandable structure.
