Cryotreatment devices and methods of ablating tissue within the body are disclosed. A cryotreatment device in accordance with an exemplary embodiment of the present invention inlcudes an elongated member having one or more needle-like ablation tips configured to induce necrosis at a target site within the heart. A cooling fluid such as a cryogen may be injected through a lumen extending into the distal portion of the device. The ablation tips can be configured to pierce and ablate surrounding tissue, blocking electrical stimuli that can cause fibrillations or other arrhythmias of the heart. The device may also include means for controlling the transmural depth at which the ablation tips are inserted into the cardiac tissue. Methods of forming a contiguous line of conduction block in accordance with the present invention are also disclosed.

L'invention concerne des dispositifs de cryothérapie et des procédés d'ablation de tissu à l'intérieur du corps. A titre d'exemple, on décrit un dispositif qui comprend un élément allongé ayant une ou plusieurs extrémités d'ablation, du type aiguille, permettant d'induire la nécrose sur un site cible dans le coeur. Un fluide de refroidissement du type cryogène peut être injecté par une lumière qui s'étend dans la partie distale du dispositif. Les extrémités d'ablation peuvent être conçues pour percer et éliminer un tissu enveloppant, en bloquant les stimuli électriques qui peuvent engendrer des fibrillations ou autres arythmies cardiaques. Le dispositif peut aussi comporter un système de contrôle de la profondeur transmurale à laquelle les extrémités d'ablation peuvent être introduites dans le tissu cardiaque. L'invention concerne enfin des procédés relatifs à la formation d'une ligne contiguë de bloc de conduction, selon les modalités décrites.
