Abstract
Abstract An implantable prosthetic device comprises a remotely detectible component disposed in the body forming the device for allowing the device to be detected by x-ray, ultrasonic, or MRI imaging. By disposing at least two remotely detectible components in the body of the device, the effective flow diameter provided by the device can be monitored. A method for monitoring a patient having a damaged or dysfunctional vascular pathway includes the steps of implanting in the patient the disclosed prosthetic device and monitoring the patency of the device by x-ray, ultrasonic, MRI, or other form of remote imaging.
