Method for vacuum-assisted tissue ablation
First Claim
1. A method of accessing and ablating abnormal epithelium tissue in a portion of an alimentary canal comprising:
- (i) inserting a vacuum source comprising one or more suction ports into the alimentary canal;
(ii) inserting an operative element comprising a conduit for a tissue ablation source into the alimentary canal;
(iii) expanding a proximal balloon and a distal balloon of the operative element to seal the portion of the alimentary canal around the abnormal epithelium tissue;
(iv) positioning the vacuum source and the operative element proximate the portion of the alimentary canal having the abnormal tissue to be ablated;
(v) applying a vacuum to at least one of each suction port to draw the tissue against the operative element; and
(vi) applying the tissue ablation source to the tissue through the conduit to effect tissue ablation.

Abstract
Methods of accessing and ablating abnormal epithelium tissue in an alimentary canal are provided. The methods can include steps of (i) inserting a vacuum source comprising one or more suction ports into an alimentary canal; (ii) inserting an operative element comprising a conduit for a tissue ablation source into the alimentary canal; (iii) positioning the vacuum source and the operative element proximate a portion of the alimentary canal having a site of abnormal tissue to be ablated; (iv) applying a vacuum to at least one of each suction port to draw the tissue against the operative element; and (v) applying the tissue ablation source to the tissue through the conduit to effect tissue ablation.
