Abstract
Medical instruments and systems for applying energy to tissue for ablating, sealing, coagulating, shrinking or creating lesions in tissue by means of contacting a targeted tissue in a patient with a vapor phase media wherein a subsequent vapor-to-liquid phase change of the media applies thermal energy to the tissue to cause an intended therapeutic effect.
Claims26
A method of performing a catheter-based medical procedure in a duodenum of a subject, comprising:
- providing a catheter with at least a first expandable member at a distal end thereof;
- expanding a first expandable member to engage a duodenal mucosa wherein a surface of the first expandable member covers a major duodenal papilla;
- and
- applying energy to the duodenal mucosa adjacent the first expandable member when expanded to ablate the duodenal mucosa.
A system for performing a medical procedure in a duodenum of a subject, the system comprising:
- an elongated catheter having a length configured for trans-esophageal introduction with a working end positioned in at least a first part, a second part and a third part of the duodenum;
- wherein the working end carries a first occlusion balloon that when expanded has an tissue-contacting surface configured to cover a major duodenal papilla and a minor duodenal papilla;
- and
- wherein the working end carries a second occlusion balloon spaced apart distally from the first occlusion balloon;
- and
- a source of vapor coupled to a lumen in the elongated catheter that communicates with at least one vapor port in the working end between the first occlusion balloon and the second occlusion balloon.
A system for performing a medical procedure in a duodenum of a subject, the system comprising:
- an elongated catheter having a length suited for trans-esophageal introduction with a working end positioned in at least a first part, a second part and a third part of the duodenum;
- wherein the working end carries a first occlusion balloon that when expanded has an tissue-contacting surface configured to cover a major duodenal papilla and a minor duodenal papilla;
- wherein the working end carries a second occlusion balloon spaced apart distally from the first occlusion balloon;
- and
- wherein the working end carries a third occlusion balloon spaced apart proximally from the first occlusion balloon.
