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 in 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.
