Title
(EN) ENDOVENTRICULAR INJECTION CATHETER SYSTEM WITH INTEGRATED ECHOCARDIOGRAPHIC CAPABILITIES
(FR) SYSTÈME DE CATHÉTER À INJECTION ENDOVENTRICULAIRE AVEC CAPACITÉS ECHOCARDIOGRAPHIQUES INTÉGRÉES
Abstract
(EN)
An endoventricular injection catheter with integrated echocardiographic capability enables injections into heart tissue under visualization. The catheter includes an elongated body having a distal end and an imaging core arranged to be inserted into a heart. The imaging core is arranged to transmit ultrasonic energy and to receive reflected ultrasonic energy at the distal end to provide electrical signals representing echocardiographic images to enable cardiac visualization. The catheter further includes an injector carried on the elongated body with the imaging core. The injector is arranged to inject a therapeutic agent into tissue of the heart visualized by the imaging core.

L'invention porte sur un cathéter à injection endoventriculaire avec une capacité echocardiographique intégrée, qui permet des injections dans un tissu cardiaque sous visualisation. Le cathéter comprend un corps allongé ayant une extrémité distale et une âme d'imagerie agencée pour être introduite dans un cœur. L'âme d'imagerie est agencée pour transmettre une énergie ultrasonore et pour recevoir une énergie ultrasonore réfléchie au niveau de l'extrémité distale pour fournir des signaux électriques représentant des images echocardiographiques pour permettre une visualisation cardiaque. Le cathéter comprend en outre un injecteur porté sur le corps allongé avec l'âme d'imagerie. L'injecteur est agencé pour injecter un agent thérapeutique dans un tissu du cœur visualisé par l'âme d'imagerie.
