Abstract

Systems and methods treat hemorrhoids by introducing a treatment device into the anal canal to extend above a hemorrhoidal plexus and adjacent a tissue region containing blood vessels that feed the hemorrhoidal plexus. The systems and methods operate the treatment device to affect tissue morphology in the tissue region to occlude or otherwise reduce blood flow through the vessels.

Claims (8)

1. A system for treating a tissue region containing blood vessels having mucosal tissue that feed a hemorrhoidal plexus, said system comprising

an energy source;

a handle, and

a treatment device coupled to the energy source, said treatment device carried by the handle having a working end sized and configured for passage into the anal canal to extend above a hemorrhoidal plexus and adjacent the tissue region containing blood vessels that feed the hemorrhoidal plexus, the treatment device including an operative element that affects tissue morphology to occlude or otherwise reduce blood flow through the vessels,

wherein said operative element further comprises a hollow barrel, wherein said barrel is transparent to enable visualization through the barrel,

the operative element supporting at least one tissue-piercing member; and

means for providing energy from said energy source to said at least one tissue-piercing member; and

means for controlling said at least one tissue-piercing member so that it may pass through the mucosal tissue of said blood vessels without penetration of the hemorrhoidal plexus.
