ABSTRACT:
An intra-luminal medical device includes a fixation mechanism to attach the medical device to tissue within a body lumen, and a detachment mechanism to permit selective detachment of the medical device from the tissue attachment site without the need for endoscopic or surgical intervention. An electromagnetic device may be provided to mechanically actuate the detachment mechanism. Alternatively, a fuse link may be electrically blown to detach the medical device. As a further alternative, a rapidly degradable bonding agent may be exposed to a degradation agent to detach the medical device from a bonding surface within the body lumen. The medical device may eliminate problems associated with uncertain and inconsistent detachment of intra-luminal medical devices.
