Claim Text:
1. A treatment catheter for repairing a cardiac valve, said catheter comprising: a catheter body having a proximal end, a distal end and a lumen extending therebetween; a containment structure near the distal end of the catheter body for creating an embolic containment region over a localized calcific site on or near a cardiac valve adjacent a blood vessel in a deployed configuration, wherein the containment structure is configured to deploy across a single leaflet of the cardiac valve and trap particles released therefrom, the containment structure having a collapsed configuration positionable within the lumen of the catheter body; and a working element adapted to disrupt the calcific site, the working element being advanceable beyond the distal end of the catheter body and positionable within the embolic containment region, wherein the containment structure is sized and shaped in the deployed configuration to isolate the single leaflet with respect to the working element such that the working element is limited to removing calcifications only from the single leaflet of the cardiac valve while the containment structure is deployed over the single leaflet.
