Patent

CA 2666660

Methods and systems are disclosed for treating diseased tissue by gentle heating. The method induces vasodilation on tissue disposed about an lumen having both healthy tissue and diseased tissue. The method includes coupling a probe surface to the luminal tissue at a target location and transmitting desired quantities of tissue remodeling energy from the coupled probe into each of a plurality of discrete remodeling zones in the luminal tissue so that the tissue remodeling energy heats the plurality of remodeling zones, the remodeling energy being configured to avoid muscular contraction and inhibit both acute and long-term occlusion of the lumen.

L'invention concerne des procédés et des systèmes pour traiter un tissu malade par un chauffage léger. Le procédé induit une vasodilatation d'un tissu disposé autour d'une lumière présentant à la fois du tissu sain et du tissu malade. Le procédé comprend : le couplage d'une surface de sonde au tissu luminal en un emplacement cible; et la transmission de quantités souhaitées d'énergie de remodelage de tissu depuis la sonde couplée dans chacune d'une pluralité de zones distinctes de remodelage du tissu luminal, de sorte que l'énergie de remodelage de tissu chauffe la pluralité de zones de remodelage, sachant que l'énergie de remodelage est configurée de manière à éviter la contraction musculaire et à empêcher une occlusion tant aiguë qu'à long terme de la lumière.
