Abstract

La présente invention concerne un appareil et un procédé permettant de pratiquer une ablation par laser, particulièrement la revascularisation transmyocardique (TMR). Pour la TMR, le procédé consiste à fournir d'abord un dispositif laser (10) pourvu d'un élément d'ablation à laser (11) (par exemple, une ou plusieurs fibres optiques), à avancer ensuite ledit élément (11) vers l'épicarde (52) d'un patient, à décharger l'énergie laser depuis l'élément précité (11) de manière à pratiquer une ablation du tissu cardiaque et créer une voie s'étendant à l'intérieur du ventricule (56) du patient, puis à émettre au moins un signal de commande depuis un capteur (18) sensible à l'ablation pour commander l'élément d'ablation à laser (11) et/ou l'énergie laser produite. L'appareil comprend un dispositif à action laser (10), pourvu d'un élément d'ablation à laser, et un capteur (18) pour capter les sons produits par l'énergie laser produite. Le capteur (18) est configuré de manière à générer et émettre au moins un signal en réaction au son détecté en direction d'un module de commande (17) associé au générateur d'énergie laser. Le module de commande (17) peut ensuite provoquer un événement en rapport avec le procédé à action laser ou signaler à l'opérateur laser qu'un événement s'est produit.
