Abstract

A system to perform a bypass procedure performed by an apparatus (100, 400, 600) comprising a steerable body portion (102, 450, 452) and at least one transducer (114, 414) controlled by at least one controller (610). The system may include one or more acts of transluminally detaching at least a portion of a first artery from connective tissue (423) of a chest wall (425) that is attached to the first artery by applying ultrasound signals of a first type emitted by the at least one transducer (114, 414) situated within the first artery; steering the detached portion of the first artery from a current location to a bypass location by applying a force from the steerable body portion, which is located outside of the first artery, to at least a portion of the detached portion of the first artery; and coupling the first artery to a target artery at the bypass location to establish flow communication between the first artery and the target artery.

Description

technical field [0001] The present system relates to systems for performing revascularization, and more particularly, to systems for performing extraluminal myocardial revascularization using an artery such as the left internal mammary artery (LIMA) and methods of operation thereof, The left internal mammary artery was harvested using transluminal cautery. Background technique [0002] Coronary artery disease is caused by a buildup of plaque in the coronary arteries that supply blood to the heart muscle. As a result, oxygenation of the muscles is insufficient, causing chronic angina and myocardial infarction. Coronary revascularization is the process of rebuilding blood flow to the heart muscle. In percutaneous coronary intervention, a stent is placed in the diseased area to open up the artery. In bypass surgery, a new catheter is attached proximally to the aorta or other non-diseased vessel and distally to the coronary arteries to bypass plaque. The most patent duct is ...
