Patent number: 7422403Abstract: A device and method for holding or clamping components together, and with the clamping being selectively loosened to permit the components to move through a predetermined distance without being fully released. A bolt has its head end attached to one component and its threaded end attached to the other component. A portion of the bolt's shank is formed with a necked-down portion. An actuator of shape memory alloy material is mounted about the bolt. When energized by heat, the actuator expands and exerts a great force which stretches the bolt, permanently deforming the bolt. This enables limited movement of the components while still restraining them from separating.Type: GrantFiled: October 25, 2004Date of Patent: September 9, 2008Assignee: Tini Alloy CompanyInventors: A.

Patent number: 7410483Abstract: The invention provides an articulating mechanism useful, for example, for remote manipulation of various surgical instruments and diagnostic tools within, or to, regions of the body. Movement of segments at the proximal end of the mechanism results in a corresponding, relative movement of segments at the distal end of the mechanism. The proximal and distal segments are connected by a set of cables in such a fashion that each proximal segment forms a discrete pair with a distal segment. This configuration allows each segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations. The articulating mechanisms may also be combined in such a way to remotely mimic finger movements for manipulation of an object or body tissue.Type: GrantFiled: November 24, 2004Date of Patent: August 12, 2008Assignee: Novare Surgical Systems, Inc.Inventors: David J. Danitz, Cameron D. Hinman

Patent number: 7403820Abstract: A neurological control system for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a “nervous system component.” The neurological control system generates neural modulation signals delivered to a nervous system component through one or more neuromodulators, comprising intracranial (IC) stimulating electrodes and other actuators, in accordance with treatment parameters. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors, each configured to sense a particular characteristic indicative of a neurological or psychiatric condition.Type: GrantFiled: May 25, 2005Date of Patent: July 22, 2008Assignee: NeuroVista CorporationInventor: Daniel John DiLorenzo
