Title (EN) TMR STENT AND DELIVERY SYSTEM
(FR) PROTHESE ENDOVASCULAIRE DE REVASCULARISATION DU MYOCARDE ET SYSTEME DE MISE EN PLACE
Abstract:
(EN) A device and method for re-vascularizing myocardial tissue of the heart using a stent (8) are provided. Multiple stents (8) are implanted into an area of hibernating myocardial tissue to permit blood to flow from the left ventricle directly into the tissue for re-vascularization. Various stent (8) embodiments are disclosed that simultaneously pierce and penetrate the tissue during delivery, and that are configured to resist migration out of the tissue once implanted. Alternatively, the stent (8) may be inserted into myocardial tissue over a piercing delivery device (104). The stents are preferably delivered through a steerable catheter (46) percutaneously inserted into the left ventricle, and configured to hold multiple stents (8). The stents (8) are pushed from the catheter directly into the myocardium sequentially.
(FR) L'invention porte sur un dispositif et un procédé de revascularisation des tissus du myocarde à l'aide de prothèses endovasculaires (8). Plusieurs prothèses endovasculaires (8) sont implantées dans une zone de tissus du myocarde en hibernation pour permettre au sang de passer directement du ventricule gauche dans les tissus pour les revasculariser. Différents types de prothèses endovasculaires (8) sont présentés qui simultanément percent et pénètrent les tissus lors de leur mise en place et sont conçus pour empêcher leur migration hors des tissus une fois implantés. En variante, la prothèse endovasculaire (8) peut être insérée dans le tissu du myocarde au-dessus d'un dispositif (104) de perçage et de mise en place. Les prothèses endovasculaires (8) sont de préférence mis en place au moyen d'un cathéter orientable (46) introduit dans le ventricule gauche par voie percutanée et conçu pour recevoir plusieurs prothèses endovasculaires (8). Les prothèses endovasculaires sont directement conduites les unes après les autres du cathéter au myocarde.
