Abstract

L'invention concerne un procédé et un dispositif améliorés destinés à inhiber ou réduire la vitesse de resténose post-angioplastie ou après la mise en place d'un extenseur. Il s'agit de mettre en place une sonde (100) à ballonnet dans la région traitée ou ouverte par le biais d'une angioplastie par ballonnet suivant immédiatement l'angioplastie. Le ballonnet, qui peut avoir une structure à deux ballonnets, peut être administré par le biais d'une sonde-guide (102) et sur un fil-guide déjà en place par une angioplastie par ballonnet. Un fluide, par exemple un perfluocarbone, peut s'écouler dans le ballonnet afin de geler le tissu jouxtant le ballonnet, ce refroidissement étant associé à la réduction de la resténose. La sonde peut également servir à réduire la fibrillation auriculaire par insertion et dilatation du ballonnet, la surface extérieure de ce dernier étant alors en contact au moins partiellement avec la périphérie de la partie de la veine pulmonaire jouxtant L'oreillette gauche.
