Patent number: 11523820Abstract: An orthopedic fixation system includes an implant and an implant insertion device. The implant transitions between a natural shape and an insertion shape. The implant includes a bridge defining a slot with a first end and a second end and first and second anchoring members extending from the bridge. The implant insertion device moves between a loaded position and an unloaded position. The implant insertion device in its loaded position inserts through the slot of the bridge and engages the bridge at the first and second ends of the slot such that the implant insertion device constrains the implant in its insertion shape. The implant insertion device in its unloaded position releases the implant.Type: GrantFiled: January 29, 2020Date of Patent: December 13, 2022Assignee: DePuy Synthes Products, Inc.Inventors: Daniel F. Cheney, Luke A. Perkins, Joseph P. Ritz

Patent number: 11051804Abstract: An orthopedic fixation system fuses bone, bones, or bone pieces in a predetermined anatomical position. The orthopedic fixation system includes an implant that transitions between an unconstrained shape and a constrained insertion shape, a drill guide, first and second K-wires, and a cannulated drill bit. The drill guide and the first and second K-wires retain the bone, bones, or bone pieces in an anatomical position corresponding with the predetermined anatomical position. The cannulated drill bit fits over the first and second K-wires and drills, respectively, first and second drilled holes into the bone, bones, or bone pieces. After insertion of the implant into the first and second drilled holes, the implant attempts to transition from its constrained insertion shape to its unconstrained shape such that the implant continuously compresses the bone, bones, or bone pieces thereby holding the bone, bones, or bone pieces in the predetermined anatomical position.Type: GrantFiled: June 25, 2019Date of Patent: July 6, 2021Assignee: Depuy Synthes Products, Inc.Inventors: Glenn Gaston, Daniel F. Cheney, Joseph P. Ritz, Eric A. Marcano, Luke A. Perkins, Diana M. Castillo Sanchez

Patent number: 10888315Abstract: An implant insertion device is adapted for use with a shape memory implant. The shape memory implant includes a bridge interconnecting first and second legs. The shape memory implant is movable between a first shape in which the first and second legs are substantially non-parallel and a second shape in which the first and second legs are substantially parallel. The implant insertion device engages the shape memory implant to maintain the shape memory implant in its second shape until the delivery of the shape memory implant into tissue or bone.Type: GrantFiled: January 9, 2019Date of Patent: January 12, 2021Assignee: BioMedical Enterprises, Inc.Inventors: Daniel F. Cheney, Joseph H. Taber, Luke A. Perkins, Joseph P. Ritz

Publication number: 20200253788Abstract: A negative pressure wound treatment (NPWT) dressing system for treating shoulder incisions. The NPWT dressing system includes a wound dressing, an immobilization device configured to immobilize a shoulder of a patient, and a negative pressure source coupled to the immobilization device. The wound dressing includes a drape layer, a manifold layer, and a reduced-pressure interface integrated with the drape layer and the negative pressure source. The drape layer has a first surface and a second, wound-facing, surface. The drape layer is substantially impermeable to liquid and substantially permeable to vapor. The manifold layer has a first surface and a second, wound-facing surface. The manifold layer has a first lobe, a second lobe substantially aligned with the first lobe, and a third lobe extending substantially perpendicular to the first lobe and the second lobe.Type: ApplicationFiled: February 3, 2020Publication date: August 13, 2020Inventors: Jonathan G. Rehbein, Richard M. Kazala, Larry Tab Randolph, Luke A. Perkins

Patent number: 5483193Abstract: A circuit and method of demodulating an FSK signal uses digital circuitry to convert the received signal into count values. For each reception an adaptive reference count value is determined by averaging the duration of received pulses during the preamble of the transmission. The adaptive reference count corresponds to a demodulated logic "1" or logic level "0". The counts from the coded portion of the transmission are compared to the adaptive reference count. If the count is within predetermined windows from the reference count, the count value is converted to the corresponding digital signal.Type: GrantFiled: March 24, 1995Date of Patent: January 9, 1996Assignee: Ford Motor CompanyInventors: John F. Kennedy, Scott O. Campbell, Lawrence P. Kirk, David P. Laude, Luke A. Perkins

Patent number: 5043633Abstract: A control circuit and method for regulating the current flow through a series connected inductor and transistor. The circuit comprises an operational amplifier for receiving a first voltage proportional to the current flow, for receiving a variable second voltage, and for providing a control current to the transistor which keeps the transistor out of its saturation region.Type: GrantFiled: November 13, 1989Date of Patent: August 27, 1991Assignee: NCR CorporationInventor: Luke A. Perkins

Patent number: 4991188Abstract: A digital frequency divider capable of providing output pulses of frequency f.sub.out related by Y/X to the frequency of the input pulses f.sub.in, where X and Y are positive whole numbers and O<Y/X.ltoreq.1. The circuit is particularly suited for high frequency digital applications. The X and Y values may be fixed or individually variable. Truncation errors decrease with time to provide a best estimate output frequency. In a preferred arrangement, iterative summations of residual and incremental values are latched and recycled as feedback in synchronism with the rate of the input frequency.Type: GrantFiled: December 12, 1988Date of Patent: February 5, 1991Assignee: NCR CorporationInventor: Luke A. Perkins
