Patent number: 10369362Abstract: An apparatus and method is related to providing sensing functions that are similar to “human touch” when located in a prosthetic device such as a BION microstimulator that is implanted in a patient. The apparatus includes a power circuit, a communication circuit and a sensor circuit. The power circuit provides power to the communication circuit and the sensor circuit. The sensor cooperates with the communication circuit, which communicates to the brain. The sensor uses various techniques to detect changes in the environment for the surrounding tissue using criteria such as reflectivity, impedance, conductivity, return signal spectrum, return signal rate and return signal phase to name a few. For example, the impedance observed by the sensor changes when: the skin tissue is deformed around the sensor, or when the skin is surrounded by water. The sensory information is interpreted by the brain as an analog of touch or feel.Type: GrantFiled: January 24, 2013Date of Patent: August 6, 2019Assignee: The Alfred E. Mann Foundation for Scientific ResearchInventors: Lawrence J. Karr, Joseph H. Schulman

Patent number: 10335089Abstract: Biocompatible stiffness enhanced pliable electrically conductive filaments configured for contact with living tissue and electrical communication with such tissue. The pliability of the filaments allows the distal end of the filaments to remain at the original site of penetration into the tissue despite the movement of the tissue relative to their surrounding environment. To temporarily stiffen the filaments, a soluble stiffness enhancing coating is disposed over the filaments. The coating may be in the form of a liquid which dries to a solid state after being applied to the filaments and renders the filaments sufficiently rigid such that under appropriate force, the filaments are capable of penetrating into dense tissue. Once in place, the stiffness enhancing coating dissolves due to contact with body fluids, the filaments, in the absence of such a coating, return to their initial pliability.Type: GrantFiled: October 14, 2016Date of Patent: July 2, 2019Assignee: The Alfred E. Mann Foundation for Scientific ResearchInventors: Joseph H. Schulman, David L. Hankin

Patent number: 8632607Abstract: Permanent magnets or electromagnets or a combination of such magnets are provided to retain a prosthetic device on an extremity or limb, such as an amputated arm. The prosthesis utilizes the opposing forces, which are developed by virtue of like magnetic poles being in proximity to each other, to urge the prosthesis to remain attached to the extremity. The prosthesis is prevented from rotation by virtue of a centering force that is provided by an attachment magnet in the prosthesis being placed between two implanted magnets. A removable mounting ring is placed over the prosthesis to maintain it on the extremity.Type: GrantFiled: May 18, 2011Date of Patent: January 21, 2014Assignee: Alfred E.

Patent number: 8428741Abstract: A method and apparatus for improving visual acuity when providing a visual image from a “high” resolution input device to a “low” resolution output device. The described invention is of particular use when the output device is an array of electrodes as part of a retinal prosthesis used to restore vision to a visually-impaired patient. In that various limitations may, within the foreseeable future, limit the density of such an electrode array (and thus the resolution of the output image), the present invention teaches techniques to assign processed pixel subsets of a higher resolution image to a single electrode. By varying the pixel subsets, e.g., by jittering, and/or altering the processing criteria, the perceived visual acuity may be further improved. Alternatively and additionally, such processing may be further extended to drive neighboring electrodes in combination to thus stimulate virtual electrode sites and thus further enhance visual acuity.Type: GrantFiled: August 2, 2011Date of Patent: April 23, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Robert J.
