The present invention provides a series of new percutaneous concepts of paravalvular repairs including identifying the leak location, several repair techniques and finally built-in means for leak prevention, built on percutaneous valves. A catheter-delivered device (27) locates cavities occurring between a prosthetic valve (20) and the wall of the body vessel where the valve is implanted, the cavities producing paravalvular leaks during diastole, the device comprising at least one of a plurality of flexible wires (28), the wire having attached to it a balloon (29), wherein the balloon is pulled by the leak through the cavity and wherein the wire then serves to mark the cavity location.
La présente invention concerne une série de nouveaux concepts percutanés de réparations paravalvulaires qui comprennent l'identification de l'emplacement de la fuite, plusieurs techniques de réparations et finalement un organe intégré destiné à la prévention de fuite ainsi que des valvules percutanées formées sur ces fuites. Un dispositif apporté par cathéter localise des cavités survenant entre une valvule prothétique et la paroi du vaisseau sur laquelle cette valvule est implantée, ces cavités produisant des fuites paravalvulaires pendant la diastole. Ce dispositif comprend au moins un fil souple parmi une pluralité de ceux-ci, un ballonnet étant fixé sur ce fil et, ce ballonnet est tiré par la fuite à travers la cavité et le fil sert ensuite à marquer l'emplacement de cette cavité.
