US Patent 8235903 Remotely controlled implantable transducer and associated displays and controls

An implantable, remotely controlled medical device that incorporates an imaging/therapy ultrasound system may be minimally invasive and equipped with an anchoring portion for securing the device within a human body. Transducers for imaging/therapy may be manipulated remotely using motors and/or selectively actuated to obtain different fields of view and stereoscopic imaging. The implantable medical device can be in the shape of a disc, double disc, sphere or pellet, for example, and may be implanted during open surgery using a manipulatable tool or using a minimally invasive image-guided sheath or catheter. The imaging system comprises one or more ultrasound transducers and can be used to provide therapy to or obtain ultrasound images of a target and surrounding volumes or focal points. The device may be controlled and report data by wired or wireless means and, if wireless, permanently worn inside the body as the patient follows their normal daily routine.
