Abstract
A system for excising an implanted clip approximating opposed valve leaflets in a heart valve includes a capture catheter configured to be introduced proximate the valve leaflets on one side of the clip, a transfer catheter configured to be introduced proximate the valve leaflets on another side of the clip, and a cutting tool configured to be deployed between the capture and transfer catheters and to be engaged against tissue of at least one of the valve leaflets and to excise the clip. A removal catheter may optionally be used to remove the clip from the heart.

A method for excising a clip approximating an opposed pair of valve leaflets in a heart valve, said method comprising:
- introducing a capture catheter into a heart chamber adjacent to the valve leaflets on one side of the clip;
- introducing a transfer catheter into the heart chamber adjacent to the valve leaflets on another side of the clip;
- deploying a cutting element from the transfer catheter to the capture catheter to place the cutting element against tissue of at least one of the valve leaflets;
- engaging the cutting member against the valve leaflet tissue;
- and
- excising the clip from at least one valve leaflet using the cutting member.
