Patent number: 11608565Abstract: Embodiments of nanostructures comprising metal oxide and methods for forming the nanostructure on surfaces are disclosed. In certain embodiments, the nanostructures can be formed on a substrate made of a nickel titanium alloy, resulting in a nanostructure containing both titanium oxide and nickel oxide. The nanostructure can include a lattice layer disposed on top of a nanotube layer. The distal surface of the lattice layer can have a titanium oxide to nickel oxide ratio of greater than 10:1, or about 17:1, resulting in a nanostructure that promotes human endothelial cell migration and proliferation at the interface between the lattice layer and human cells or tissue. The nanostructure may be formed on the outer surface of an implantable medical device, such a stent or an orthopedic implant (e.g. knee implant, bone screw, or bone staple).Type: GrantFiled: December 14, 2021Date of Patent: March 21, 2023Assignee: Alfred E.

Patent number: 10885148Abstract: A medical classification code modeling system and method that generates visual maps in response to user queries, where the visual maps represent combinations of modifiers of an interface terminology that, taken together, map to medical classification code elements. The system and method may present multiple visual maps on the same display to permit visual analysis of multiple mapping revisions or versions. The system and method further may integrate into an electronic health record such that the user's ultimate selection of a mapping results in the corresponding medical classification code being inserted into the record of a patient at an appropriate location, such as on the patient's problem list.Type: GrantFiled: August 4, 2015Date of Patent: January 5, 2021Assignee: INTELLIGENT MEDICAL OBJECTS, INC.Inventors: Regis Charlot, Frank Naeymi-Rad, Michael Decaro, Steven Rube, Eric Rose, Andrew Kanter, David Parks, Daniel Emmons, Alina Oganesova, David Alvin, Matthew Cardwell

Patent number: 10196604Abstract: Disclosed are certain heterocyclic organic compounds that inhibit mitochondrial respiration and also lead to the maintenance of pluripotency of human embryonic stem cells in culture, even in the presence of oxygen. Exemplified are compounds, such as substituted 5-aminotetrazoles, which are reversible mitochondrial inhibitors. The pluripotency of the stem cells after culture is verified by the overexpression of pluripotent stem cell markers, exemplified by at least one of the genes NANOG, OCT4, and SURVIVIN after periods of culture in ambient oxygen.Type: GrantFiled: June 19, 2015Date of Patent: February 5, 2019Assignees: The Board of Trustees of the Leland Stanford Junior University, Board of Regents of the University of Texas SystemInventors: David Alvin Tyvoll, Christopher S.

Patent number: 9918964Abstract: It has been discovered that inhibiting mitochondrial respiration in platelets reduces platelet activation or platelet aggregation. Certain heterocyclic compounds significantly reduced one or more platelet functions including clumping, sticking or platelet-stimulated clotting. Thus diseases or disorders mediated by inappropriately high levels of platelet activation or platelet aggregation can be treated by administering a therapeutically effective amount of a heterocyclic compound or nonheterocyclic mitochondrial inhibitor that significantly reduces one or more platelet functions including clumping, sticking or platelet-stimulated clotting, preferably in a reversible manner.Type: GrantFiled: April 25, 2011Date of Patent: March 20, 2018Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: James P.

Patent number: 9840310Abstract: A seat module suspension system for a high-speed water vessel including a guide assembly for permitting a range of substantially vertical travel of the seat module, an air shock within the guide assembly for resiliently suspending the seat module; and a support assembly extending for impeding athwart movement of a forward projecting portion of the seat module. The support assembly includes a spar pivotally mounted at one end the base of the guide assembly and pivotally mounted at the other end to a mount attached to the underside of the forward projecting portion and configured to permit fore and aft movement, so as to accommodate substantially vertical movement of the seat module. The system also includes a second air shock connected to the support assembly to impede the fore and aft movement and thus support the forward projecting portion of the seat module.Type: GrantFiled: February 29, 2016Date of Patent: December 12, 2017Assignee: Professional Components Ltd.Inventors: David Alvin Smith, Lee Michael Adams

Patent number: 9594872Abstract: A method for implementing an interface terminology is described, the interface terminology comprising concepts and descriptions, a description being an alternative way to express a concept. The interface terminology also may include a plurality of domains, wherein each concept is unique within a domain. The method may include the steps of: storing a plurality of concepts in a database; storing a plurality of descriptions in a database; linking each description to a respective concept; storing an external code set in a database, the external code set comprising a plurality of external codes; and mapping an external code to a concept. The steps may occur via database table mapping. The method also may include deploying a front-end file, the front-end file comprises a link between the descriptions and the external code set.Type: GrantFiled: October 25, 2012Date of Patent: March 14, 2017Assignee: Intelligent Medical Objects, Inc.Inventors: Fred E.

Patent number: 9422039Abstract: A suspension system for passenger modules or marine platforms used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the marine platform relative to the vessel. The marine platform is attached to the vessel via an assembly of pivoting spars in which the vessel attachment locations are spaced athwart a greater distance than the marine platform, and the attachment of some spars permits relative fore and aft movement between the spars and the marine platform or the vessel to accommodate pitch. The suspension system may include components for attenuating motion associated with roll.Type: GrantFiled: March 4, 2015Date of Patent: August 23, 2016Assignee: Professional Components LTDInventors: David Alvin Smith, Lee Michael Adams
