Abstract
An instrument and method for tissue thermotherapy including an inductive heating means to generate a vapor phase media that is used for interstitial, intraluminal, intracavity or topical tissue treatment. In one method, the vapor phase media is propagated from a probe outlet to provide a controlled vapor-to-liquid phase change in an interface with tissue to thereby apply ablative thermal energy delivery.
Claims21
A method for altering a function of a wall of a duodenum of a digestive tract of an individual, the method comprising:
- advancing a working end of a catheter device into the duodenum using a trans-esophageal approach, where the catheter device is configured deliver a flow media
- converting the flow media to a heated flow media using a heating mechanism remote from the working end;
- causing an inflow the heated flow media to the working end using a pressure source through a first flow channel to deliver a controlled thermal energy to a wall of the duodenum in a plurality of adjacent sections to produce a plurality of thin layers of ablated tissue in adjacent sections of the wall of the duodenum such that plurality of thin layers of ablated tissue alter the function of the digestive tract;
- causing an outflow of the heated flow media through a second flow channel extending through the catheter device from the working end;
- and
- controlling the heating mechanism and the pressure source using a controller to control heating of the heated flow media and inflow of the heated flow media to the working end.
A method for treating a targeted site in a lumen of a small intestine of a patient, the method comprising:
- manipulating a working end of an elongated catheter to a target site in the lumen of the small intestine via a trans-esophageal approach;
- positioning an energy applicator portion of the working end of the elongated catheter at the target site;
- engaging at least one balloon coupled to the working end against a wall of the small intestine;
- heating a flow media using an energy delivery source to convert the flow media to a heated flow media;
- producing pressure from a pressure source to cause a flow of the heated flow media through a first flow channel in the elongated catheter to the energy applicator portion;
- allowing an outflow of the heated flow media from the energy applicator portion through a second flow channel extending through the elongated catheter;
- and
- using a controller to control the energy delivery source and the pressure source to control the flow of the heated flow media at a selected temperature such that the heated flow media delivered through the energy applicator portion applies thermal energy to the wall of the small intestine at the targeted site to ablate a thin layer of the wall causing an alteration of hormonal function of the patient.
