Title
(EN) CRYO-BALLOON WITH DIRECTIONAL GAS CONTROL
(FR) CRYO-BALLONNET COMPRENANT UNE COMMANDE DIRECTIONNELLE DE GAZ
Abstract
(EN)
Embodiments of the present invention provide a medical probe that includes an insertion tube, an inflatable balloon, and injection tube and a directional control tube. The insertion tube has a distal end configured for insertion into a body cavity and contains a lumen that opens through the distal end. The inflatable balloon is deployable through the lumen into the body cavity. The injection tube extends from the lumen into the balloon and includes a plurality of apertures, which are distributed radially around the injection tube and open into the balloon, and which are configured for delivery of a refrigerant from the injection tube into the balloon. The directional control tube surrounds and is rotatable around the injection tube and includes a semi-tubular section that is configured to cover one or more of the apertures, thereby blocking exit of the refrigerant through the one or more of the apertures.

Selon ses modes de réalisation, la présente invention concerne une sonde médicale qui comprend un tube d'insertion, un ballonnet gonflable et un tube d'injection et un tube de commande directionnelle. Le tube d'insertion a une extrémité distale conçue pour s'insérer dans une cavité corporelle et contient une lumière qui s'ouvre à travers l'extrémité distale. Le ballonnet gonflable peut se déployer à travers la lumière dans la cavité corporelle. Le tube d'injection s'étend à partir de la lumière dans le ballonnet et comprend une pluralité d'ouvertures, qui sont réparties radialement autour du tube d'injection et ouvertes dans le ballonnet et qui sont conçues pour alimenter le ballonnet en fluide frigorigène provenant du tube d'injection. Le tube de commande directionnelle entoure et peut tourner autour du tube d'injection et comprend une partie semi-tubulaire conçue pour recouvrir au moins une ouverture, bloquant ainsi la sortie du fluide frigorigène à travers ladite ou lesdites ouvertures.
