Abstract: The invention relates to endovascular medical implant devices, systems and methods that including a sensing device and a flow diverter device, which are effective to monitor intra-/post-operative hemodynamic properties in the location of a cerebral aneurysm and, hemodynamic alterations following placement of the system for treating ischemic diseases in carotid, coronary and peripheral arteries. The sensing device includes wireless, non-thrombogenic, highly stretchable, ultra-low profile flow sensors.

Abstract: The system includes various embodiments of components, including (1) a sensor array, (2) a processor, (3) a transmitter, (4) a receiver-stimulator, and (5) an implantable electrode array. The gustatory implant system generates tastant fingerprints by detecting tastants with an array of chemical sensors and then transmitting variable spatiotemporal stimulation patterns for an electrode array with electrode stimulating points positioned at different locations in the gustatory cortex (e.g., stimulating the chorda tympanic nerve). Different patterns of activity in the gustatory cortex are thereby generated which mimic the sense of taste in a subject. Once trained the system should be usable by a subject to detect or correctly identify or perceive one or more tastes. The system may also include an external electronic device for processing and displaying information to monitor ingestion of various substances in a subject.

Abstract: Methods and systems for tracking ocular vergence movements of an eye of a person are described. The methods and systems involve placement of flexible/stretchable skin-like electrodes on a person's head and recording the biopotential or electrooculogram of the person as the eye or eyes move to different focal positions, such as near distances, intermediate distances, and far distances. A data acquisition unit can record the electrooculogram and transmit the electrooculogram data to a computer for classification or for further processing. The data can be used with ophthalmic devices to provide a visual change for a person with the ophthalmic device.

Abstract: A motion compensation system includes a plurality of RF transmitters, a plurality of direction of arrival sensors, and a positioning table which together are usable to compensate for intrafraction motion of a patient during a medical procedure. The positioning table may be a secondary table arranged next to or above a primary table such as a radiotherapy couch, allowing for repositioning of part of patient such as the head and neck relative to a remainder of the body. The motion compensation system employs a direction of arrival sensor that includes rotating antenna elements in a configuration that improves the ease and accuracy of signal processing and analysis to identify the position of an RF transmitter affixed to a patient. The repositioning table has six degrees of freedom and is safe for use in imaging and radiation intensive environments.
