REMOVABLE IMPLANTABLE DEVICE

摘要

A removable implanted device (10) is provided which monitors the blood flow in a vessel (22) and can be removed through the insertion wound (20) without additional surgery. The device has an elongated probe body (12) which contains a Doppler-type ultrasonic transducer (40) attached to the probe body at an angle so as to enable monitoring of blood flow when attached to the vessel (22). The device has a flexible tube (18) which extends out of the bo dy through the insertion wound (20). The device is held in place against the vessel (22) by sutures (38) which are secured to the probe body (12) by a suture attachment wire (24, 26) which may be bent or looped to form two substantially equal lengths (24, 26). Alternate embodiments use a release wire (62) or a balloon (70) to secure the sutures (38) to the probe body (12).
