APPARATUS AND METHODS FOR RECAPTURING AN ABLATION BALLOON
First Claim
1. A recapturing apparatus, comprising:
- a moveable collar sized to fit within a guide sheath, the collar having a distal capture region sized to fit over and radially compress an expandable body disposed at a distal end of a catheter shaft, a proximal attachment region, and a central lumen sized to receive the catheter shaft therein; and
a push wire having a distal end configured to engage the attachment region, thereby affixing the push wire to the collar.

Abstract
A recapturing apparatus, a medical kit including the recapturing apparatus and a method for performing a medical procedure using the recapturing apparatus are provided. The recapturing apparatus includes a moveable collar and a push wire. The moveable collar comprises a proximal attachment region and a distal capture region sized to capture an expandable body therein. The push wire is configured to couple to the attachment region. The medical kit includes a sheath, a catheter having a distally-located expandable body, and the recapturing apparatus located concentrically between the sheath and the catheter. The method for performing the medical procedure includes coupling the push wire to the collar and advancing the collar distally along the catheter until the expandable body on the catheter is captured within the collar.
