Abstract
Systems, methods, and devices providing for improved safety for an Intravascular Implantable Device (IID) are described herein. The IID includes a dislodgement detector that may include at least one accelerometer device and/or one or more microphones. In various embodiments, the accelerometer device is adapted to sense various forces or motions such that a dislodgement event may be detected. In one embodiment, the detector is adapted to sense movement of the IID through the vascular system as a result of dislodgement. In another embodiment, the detector is adapted to detect and compare accelerations caused by the force of gravity to determine a dislodgement event. In various embodiments, the detector includes a multi-axis accelerometer. In one such embodiment, the detector is adapted to detect an orientation of the IID in order to determine a dislodgement event.
