Abstract
Methods treat a tissue region. In one arrangement, the methods deploy an electrode on a support structure in a tissue region at or near the cardia of the stomach. In one embodiment, the support structure has a proximal region and a distal region. The proximal region is enlarged in comparison to the distal region, and the electrode is carried by the enlarged proximal surface. The methods advance the electrode in a path to penetrate the tissue region and couple the electrode to a source of radio frequency energy to ohmically heat tissue and create a lesion in the tissue region.
Claims7
A method of accessing and ablating abnormal tissue in a human esophagus, comprising the steps of:
- (i) inserting an expandable member into a human esophagus wherein the expandable member is connectable to a power source for generating radio frequency energy,
- (ii) positioning the expandable member proximate a portion of the human esophagus having tissue to be ablated;
- (iii) expanding and positioning the expandable member so as to apply radio frequency energy to a site of abnormal tissue for ablation of the tissue;
- and
- (iv) providing ablation energy to a portion of the expandable member to effect tissue ablation.
