Patent number: 11974926Abstract: The improved endoprosthetic device surface treatment encourages soft tissue attachment thereto. A porous mesh surface treatment creates on an outer surface of the endoprosthetic device a three-dimensional surface structure similar to cancellous bone. Suture attachment features are provided at various locations around the treated surface structure to initially affix a vascularized soft tissue to the treated surface. As the patient heals the soft tissue grows and infiltrates the porous mesh surface to achieve an attachment strength substantially equal to the surrounding tissue.Type: GrantFiled: October 25, 2019Date of Patent: May 7, 2024Assignee: Onkos Surgical, Inc.Inventor: Gerhard E.

Publication number: 20220338997Abstract: An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.Type: ApplicationFiled: June 29, 2022Publication date: October 27, 2022Inventor: Gerhard E. Maale

Patent number: 11344422Abstract: The improved glenoid fossa prosthesis for repair of a scapular deficient patient includes a base with a fixed flange, and a separable flange. A conical taper on the base and a complimentary locator edge positively orient the separable flange when joined with the base for affixation by screw. A plurality of flange fixation screws penetrates the scapular tissue between the flanges for affixation of the flanges thereto. The flange thickness is variable to approximate the topography of the scapular tissue in the affixation area to minimize tissue trimming during fitment. A cutting mask attaches to the deficient scapula in the glenoid fossa area to guide the physician in trimming scapular tissue for fitment. A cortical screw further fixates the base to the scapular tissue. A second conical taper on the base serves as a mount for a glenoid sphere (reverse shoulder) or socket (standard shoulder) repair configuration.Type: GrantFiled: October 18, 2019Date of Patent: May 31, 2022Inventor: Gerhard E.
