CA 2615267

Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Additional embodiments include a system that includes an interface unit for delivering one or more forms of energy to the ablation catheter.

L'invention concerne des dispositifs, des systèmes et des procédés d'ablation d'un tissu. Des modes de réalisation mettent en oeuvre un cathéter d'ablation comportant un ensemble d'éléments d'ablation fixés à un ensemble support déployable. L'ensemble support peut être confiné à l'intérieur de la lumière d'un cathéter puis amené dans un état déployé. L'ensemble support comprend plusieurs électrodes configurées pour l'ablation d'un tissu à basse puissance. D'autres modes de réalisation comprennent un système présentant une unité d'interface destinée à transmettre une ou plusieurs formes d'énergie au cathéter d'ablation.
