Patent number: 8985119Abstract: A nerve-stimulation device and method using light to provide a source of precise stimulation on one or more nerve fibers. In some embodiments, this simulation is provided through a device and method wherein a laser- or LED-light-generating source is operatively coupled to an optical fiber, which in turn is coupled to a plug in the end of a holder in a sheath. Light is then passed from the light source through the optical fiber to the holder and out a selected optical tip on the sheath to provide an efficacious amount of light to simulate nerves. In some embodiments, the device is constructed from non-magnetic material such as glass, plastic or ceramics. In some embodiments, the light emanating from the optical tip can be controlled manually or automatically. Some embodiments omit the fiber and use light directly from the laser diode.Type: GrantFiled: June 9, 2010Date of Patent: March 24, 2015Assignee: Lockheed Martin CorporationInventors: James S. Webb, Charles E. Hamilton, Heather A. Ralph, Mark P. Bendett, Charles A. Lemaire

Patent number: 8929973Abstract: Medical researchers use various optical devices for diagnosis, detection, treatment, and therapy. In some embodiments, they do not have the equipment necessary to determine how much light is emitted by the optical device or how far it penetrates tissue. The present invention provides for a method and apparatus for characterizing light from an optical device by using a tissue phantom. The method includes coupling light from an optical source into a device, transmitting the light through a tissue phantom, detecting a transmitted light, optionally electrically processing the detected output, and displaying the corresponding optical characterization. In some embodiments, the apparatus obtains input light from an optical source, and may include a tissue phantom, an optical detector, an electrical processing unit, and a display for displaying the corresponding optical characterization.Type: GrantFiled: November 30, 2007Date of Patent: January 6, 2015Assignee: Lockheed Martin CorporationInventors: James S.

Patent number: 8792978Abstract: Apparatus and method for optical- or optical-and-electrical stimulation of e.g., auditory nerve pathways, for example spiral ganglion in the cochlea or neurons in the cochlear nerve. Several configurations for guiding and directing the optical stimulation are disclosed. Several configurations for guiding and directing the electrical field (used in some embodiments, for sensitization) in and through the destination tissue to which the optical stimulation is directed are disclosed. In some embodiments, and array of IR VCSELs emit stimulation light, in particular to tissue in the cochlea for restoring hearing. In some embodiments, an electrical signal is also applied in a manner that reduces the amount of light in a pulse that is otherwise needed to elicit a NAP. In some embodiments, a heat dissipater is used to spread the heat generated by operation of the lasers and their circuits, to avoid heat damage to the tissue.Type: GrantFiled: September 24, 2010Date of Patent: July 29, 2014Assignee: Lockheed Martin CorporationInventors: Jonathon D.

Patent number: 8498699Abstract: An apparatus and method for stimulating animal tissue (for example to trigger a nerve action potential (NAP) signal in a human patient) by application of both electrical and optical signals for treatment and diagnosis purposes. The application of an electrical signal before or simultaneously to the application of a NAP-triggering optical signal allows the use of a lower amount of optical power or energy than would otherwise be needed if an optical signal alone was used for the same purpose and effectiveness. The application of the electrical signal may precondition the nerve tissue such that a lower-power optical signal can be used to trigger the desired NAP, which otherwise would take a higher-power optical signal were the electric signal not applied. Some embodiments include an implanted nerve interface having a plurality of closely spaced electrodes placed transversely and/or longitudinally to the nerve and a plurality of optical emitters.Type: GrantFiled: January 26, 2011Date of Patent: July 30, 2013Assignees: Lockheed Martin Company, Vanderbilt UniversityInventors: Jonathon D.
