Abstract
The present invention provides an electrical block implant sized and shaped for securement at the perimeter of the pulmonary ostium of the left atrium. By utilizing various expandable ring designs and optional anchoring mechanisms, the present invention causes even, circular scarring around the perimeter of the pulmonary ostium, achieving reliable blocking of aberrant electrical signals responsible for atrial fibrillation.
Claims11
A method of treating an atrial arrhythmia comprising:
- delivering an unexpanded implant to a target site in an ostial region of a pulmonary vein;
- expanding said implant to an initial retention state wherein said implant substantially conforms to a wall in said ostial region of said pulmonary vein;
- and,
- allowing said implant to continue to expand over time such that said implant migrates through an entire thickness of said wall of said pulmonary vein, said migration causing a circumferential scar tissue response of said pulmonary vein that treats said atrial arrhythmia.
1 more element
A method of creating an electrical conduction block in a pulmonary vein ostial region comprising:
- directing an implant towards said ostial region in said pulmonary vein;
- retaining said implant in said pulmonary vein with a first component of said implant;
- expanding a second component of said implant independently relative to said first component of said implant;
- and
- causing the formation of circumferential scar tissue in said ostial region of said pulmonary vein by allowing said second component of said implant to migrate into said ostial region.
