Method and device for permanent vessel occlusion
First Claim
Patent Images
1. A method for occluding a body lumen, said method comprising:
- applying from within the lumen a force to draw opposed portions of the inner lumen wall at least partially together over an occlusion region, wherein said opposed portions are disposed across the lumen from each other; and
injuring opposed portions of the inner wall while they are held together by the applied force, wherein the injured region heals to form an occlusion blocking the body lumen.

Abstract
Body lumens such as blood vessels are selectively occluded by mechanically collapsing the blood vessel and subsequently applying energy or other occlusive conditions within or adjacent the collapsed region. For example, vessel collapsing mechanisms can include spreadable opposed elements, reciprocating jaw mechanisms having penetrating elements, and devices for applying negative pressure to collapse the blood vessel. One or more electrodes can be used in a monopolar or bipolar fashion to apply radiofrequency or other energy to the body lumen in the region where it has been collapsed.

3. A method for occluding a body lumen, said method comprising:
-
advancing a probe through the lumen to a target site; applying a force through the probe to draw opposed portions of the inner lumen wall together over an occlusion region, wherein the opposed portions lie across the lumen from each other; engaging at least one electrode on the probe against the lumen wall in or near the occlusion region; and initiating a radiofrequency current flow from the probe through the lumen wall at the occlusion region, wherein the current flow causes injury to the inner lumen wall in the occlusion region, wherein the injured region heals to form an occlusion blocking the body lumen. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)
