Publication number: 20240335291Abstract: An orthopedic implant includes a first surface, a second surface, and a first body portion extending between the first surface and the second surface to define a thickness of the implant. The first body portion includes a first porous section defining pores, solid bounding struts including a first set of bounding struts, and a first bone screw hole extending through a thickness of the implant. Each of the struts of the first set of bounding struts bound the first porous section. The first set of bounding struts include a first curved strut that further bounds a portion of a perimeter of the first bone screw hole.Type: ApplicationFiled: April 5, 2024Publication date: October 10, 2024Inventors: Zz Haggerty, Shammodip Roy, Alexander Slayton, Lewis Mullen, Richard Wood, Michael Ferko, Peter Tulkis

Patent number: 12064356Abstract: An acetabular implant kit includes a first acetabular component that has an inner surface that defines a first concave profile. A second acetabular component includes an inner surface that defines a second concave profile. An instrument includes an elongated body that has a first end and a second end. A head is connected to the second end of the body and has an engagement surface. The engagement surface includes a first convex profile and a second convex profile. The first and second convex profiles are arranged along a longitudinal axis of the head and have a first radius of curvature configured to congruently engage the first concave profile of the first acetabular component. The second convex profile has a second radius of curvature configure to congruently engage the second concave profile of the second acetabular component. The first radius of curvature is different than the second radius of curvature.Type: GrantFiled: August 19, 2022Date of Patent: August 20, 2024Assignee: Howmedica Osteonics Corp.Inventors: Shammodip Roy, Matthew P. Abdel

Publication number: 20230135274Abstract: A milling module for converting bone stock into bone chips comprises a shell adapted for releasable attachment to a base module. The shell has an inlet opening through which bone stock is introduced into the shell and an outlet opening through which bone chips are discharged from the shell. A milling element is moveably disposed in the shell between the inlet opening and the outlet opening for converting bone stock into bone chips. The shell includes a base adapted for releasable attachment to the base module. The base includes the outlet opening and a lid removably attached thereto. The lid includes the inlet opening of the shell. The base and the lid are collectively configured so that removal of the lid from the base allows the milling element to be accessed.Type: ApplicationFiled: December 29, 2022Publication date: May 4, 2023Applicant: Stryker CorporationInventors: Robin B. W. Babaris, Aaron Hoffmann, Clifford Edwin Lambarth, Derek F. Nelson, Steven M. Rolfsen, JR., Shammodip Roy, James Walen, Jason James Wroblewski

Patent number: 11564813Abstract: A milling module (60) for converting bone stock into bone chips comprises a shell (34) adapted for releasable attachment to a base module (32). The shell has an inlet opening (152) through which bone stock is introduced into the shell and an outlet opening (96) through which bone chips are discharged from the shell. A milling element (170) is moveably disposed in the shell between the inlet opening and the outlet opening for converting bone stock into bone chips. The shell includes abase (62) adapted for releasable attachment to the base module. The base includes the outlet opening and a lid (126) removably attached thereto. The lid includes the inlet opening of the shell. The base and the lid are collectively configured so that removal of the lid from the base allows the milling element to be accessed.Type: GrantFiled: May 25, 2018Date of Patent: January 31, 2023Assignee: Stryker CorporationInventors: Robin B.

Patent number: 11399945Abstract: In one embodiment, the present disclosure relates to an acetabular implant system with a liner and a sleeve. The liner includes a convex outer surface shaped to correspond to an interior of an acetabular cup and has an equatorial region and a polar region. The convex outer surface includes a plurality of liner engagement features thereon. The sleeve includes an inner surface with a plurality of sleeve engagement features thereon. The inner surface of the sleeve is sized to be flush with the convex outer surface of the liner. When the sleeve is engaged with the liner, the liner engagement features engage the sleeve engagement features.Type: GrantFiled: January 23, 2020Date of Patent: August 2, 2022Assignee: Howmedica Osteonics Corp.Inventors: Shammodip Roy, Arlen Dale Hanssen, Matthew P. Abdel, Mark W. Pagnano

Publication number: 20220117745Abstract: A self-broaching, neck-preserving hip stem includes a set of rasp teeth on a distal-lateral portion of the stem to allow the stem to be impacted into a femur without the use of surgical broaches. The rasp teeth are disposed on a relief surface. The stem includes a length, radius of curvature, and a dual-taper in the anterior-posterior and distal-lateral directions which allow the neck to self-broach and seat itself proximal to the conventional resection level to preserve greater bone stock in the femur.Type: ApplicationFiled: October 12, 2021Publication date: April 21, 2022Applicants: Howmedica Osteonics Corp., Howmedica Osteonics Corp.Inventors: Shammodip Roy, Daniel Rudolf Scholl, Tyler Saunders
