An apparatus (50) and method for protecting the neurovascular bundle (NVB) during cryoablation of tissues of the prostate by heating the vicinity of the NVB while cooling pathological tissues of a prostate to cryoablation temperatures, thereby cryoablating pathological tissues while protecting the NVB from damage. A cryoprobe (50) operable to cool a distal operating tip while heating a proximal shaft is presented.
L'invention concerne un appareil et une méthode de protection du paquet vasculo-nerveux pendant la cryo-ablation de tissus de la prostate. La méthode consiste à chauffer la zone située à proximité du paquet vasculo-nerveux tout en refroidissant les tissus pathologiques d'une prostate jusqu'à atteindre des températures de cryo-ablation, ce qui permet d'effectuer une cryo-ablation des tissus pathologiques tout en protégeant le paquet vasculo-nerveux contre des lésions. Une cryo-sonde utilisée pour refroidir une pointe fonctionnelle distale tout en chauffant une tige proximale est décrite.
