Assignee:

Ormco Corporation - Orange CA

International Classification:

A61C 3/00

US Classification:

433 10

Abstract:

An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and the movable member may be made from a transparent or translucent polycrystalline ceramic for improved aesthetics. The polycrystalline ceramic has a grain size distribution characterized by an average grain size in the range of larger than 3. 4 μm to about 6 μm. The polycrystalline ceramic may have a fracture toughness of at least 4. 0 MPam1/2. The grain size distribution may not be characterized as a lognormal distribution and may be a multimodal distribution. The polycrystalline ceramic may comprise aluminum oxide or alumina. The grain size distribution may be characterized by having up to about 50% of the grains being less than about 3 μm in size.

US Classification:

433 10, 433 13

Abstract:

An orthodontic bracket for coupling an archwire with a tooth includes a bracket body that has an archwire slot adapted to receive the archwire. A movable member is engaged with the bracket body and is movable between an opened position and a closed position. The bracket body and movable member are made from a transparent or translucent ceramic for improved aesthetics. The bracket body may include one or more stop surfaces that limit movement of the moveable member in the gingival direction. The bracket body may include a support surface that is positioned lingually of a labial edge of the archwire slot. The moveable member may include a bracket-engaging portion having a first surface confronting the bracket body and a slot-covering portion having a second surface confronting the archwire slot, the first and second surfaces being offset from one another.

International Classification:

A61N 1/05

US Classification:

607116, 607 17, 607115, 607119

Abstract:

An implantable lead includes a lead body, having a distal end and a proximal end, configured to be implanted in a patient, and a connector provided at the proximal end. A load detection assembly is provided on the lead body, wherein the load detection assembly includes a housing that holds a sensor and a load transfer element. The load transfer element engages the sensor and conveys a force induced on the load transfer element to the sensor. Optionally, the housing may isolate the sensor from lateral forces and the load transfer element may only convey, to the sensor, longitudinal forces that are directed in a predetermined single direction. For example, the load transfer element may only convey, to the sensor, longitudinal forces that are directed perpendicular to a surface of the sensor.

International Classification:

H01M 4/46
H01M 4/08

US Classification:

4292316, 296231, 429246

Abstract:

A bioelectric battery used to power an implantable device comprises an anode electrode and a cathode electrode separated by an insulating member. The anode is formed from a nanocrystalline or ultra fine grain sized magnesium alloy. The magnesium alloy can be formed by subjecting a starting magnesium alloy to one or more plastic deformation treatments to reduce grain size and improve uniform material distribution, thereby reducing corrosion loss and improving service life.

US Classification:

607 22, 607 62

Abstract:

A glycemic condition is indicated based on variance of a feature derived from cardiac electrogram data. Neurostimulation is then used to counteract a cardiac-related autonomic response to the glycemic condition. For example, stimulation of parasympathetic innervation may be used to counteract an autonomic sympathetic response that is associated with hypoglycemia or hyperglycemia. In addition, stimulation of sympathetic innervation may be used to counteract an autonomic parasympathetic response that is associated with hypoglycemia or hyperglycemia.

US Classification:

433 10, 264 16

Abstract:

An orthodontic bracket for coupling an archwire with a tooth. The orthodontic bracket comprising a ceramic injection molded (CIM) bracket body including an archwire slot that is configured to receive the archwire therein. The CIM bracket body comprising a polycrystalline ceramic. A coating of alumina or silicon dioxide is in continuous and direct contact with at least the surfaces of the archwire slot. The orthodontic bracket is characterized by unexpectedly high torque strength. The ceramic injection molded (CIM) bracket body may comprise a polycrystalline ceramic having a grain size distribution characterized by an average grain size in the range of larger than 3.4 μm to about 6 μm such that the orthodontic bracket is also characterized by unexpectedly high fracture toughness. A method of making the orthodontic bracket comprises injection molding a bracket using a ceramic powder, sintering the molded bracket, and coating the ceramic injection molded bracket.
