Publication number: 20140180431Abstract: Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.Type: ApplicationFiled: February 25, 2014Publication date: June 26, 2014Applicant: Smith & Nephew, Inc.Inventors: Justin Steve Conway, David C.

Publication number: 20140128874Abstract: Systems and methods provide patient-specific cutting blocks that allow for bone resurfacing procedures, such as milling or burring, with simplified devices. A computer assisted surgical cutting block is produced having a surface region that matches with the surface region of a patient's bone to be altered. A cutting tool may be provided having a contoured bone mating surface and a contoured and patient-specific shaped cutting guide surface, which is located in a plane above the bone mating surface. One or more channels are provided in the cutting block, and as the surgeon moves the cutting tool (a milling or burring, for example) in the channels the tool cuts the bone both laterally along the surface of the bone and vertically into the bone according to the cutting guide surface and other preselected surface features of the cutting block.Type: ApplicationFiled: August 16, 2011Publication date: May 8, 2014Applicant: SMITH & NEPHEW, INC.Inventors: Luke Andrew Gibson, Jeffrey A.

Publication number: 20140109479Abstract: A retractor element includes a rigid slide connected between a latch bolt and a solenoid plunger for movement between a first position and a second position, the slide operably connected to plunger. A pivoting link defines a slot having an inner end portion extending transversely, the slot configured for pivoting the link when the slide moves between the first position and the second position of the slide. When the retracting mechanism is energized the plunger retracts causing movement of the slide to the second position of slide and the pin to enter the transverse end of the slot in the link. A bearing surface intersects the path of movement of the pin such that significantly less current is required for retaining the plunger in the retracted position than to retract the plunger for blocking the return of the latch bolt to the projected position.Type: ApplicationFiled: October 18, 2013Publication date: April 24, 2014Applicant: Yale Security Inc.Inventors: Scott G. Morstatt, Jeffrey Sharps, Anthony Benitez

Patent number: 8657824Abstract: Instruments for use in anterior approach total hip arthroplasty. Instruments according to certain embodiments of the invention connect to a shaping member such as a broach, reamer or osteotome that is used to prepare the intramedullary canal of a desired femur or other bone for total hip arthroplasty. Such an instrument according to such embodiments can be configurable to allow operation on either the left or right leg, and in doing so to provide lateral offset and anterior offset of the instrument handle relative to the shaping member so that the patient's gut, musculature or other bodily portions may be avoided while still providing desired leverage and control over the shaping member to prepare the intramedullary canal.Type: GrantFiled: November 20, 2009Date of Patent: February 25, 2014Assignee: Smith & Nephew, Inc.Inventors: Jeffrey A. Sharp, Luke A. Gibson, David C. Kelman

Publication number: 20140008373Abstract: A multilayer liner for a high-pressure gas cylinder is provided. The liner has an impact-modified polyamide (PA) layer in contact with the high-pressure gas. The impact-modified PA layer reduces travel of the high-pressure gas from the inside of the liner to the outside of the liner. Use of a gas barrier layer such as an EVOH layer in combination with the impact-modified PA layer results in improved permeation resistance not heretofore demonstrated in a Type 4 cylinder. Combination of the EVOH layer and the impact-modified PA layer results in an interior surface which is compatible with gas environment in the cylinder, ductility at high pressures, a range of temperatures, and can survive cryogenic conditions.Type: ApplicationFiled: March 29, 2012Publication date: January 9, 2014Applicant: Luxfer Canada LimitedInventors: Jeffrey Sharp, Joel Runka
