Abstract
Implantable medical devices, including stents, grafts, covered stents, catheters, patches or the like having regions of the device which are functionalized employing microelectromechanical systems that are capable of acting as electromechanical sensors or biosensors in response to either an endogenous event, such as tissue growth, biochemical binding events, pressure changes, or respond to an externally applied stimulus, such as RF energy, to cause a change in the state of the device, such as to induce an oscillation signal which may be interrogated and interpreted external the body or may generate an induced electrical or electromagnetic potential in the device to activate micromotors to effect a geometric change in the device.
