Gregory Thomas Van Der Meulen - Ketchum ID, US

International Classification:

A61F 2/38

US Classification:

623 2011, 623 2012, 606 99

Appl. No.:

13/193230

Inventors:

Randall Lane Acker - Ketchum ID, US
Gregory Thomas Van Der Meulen - Ketchum ID, US

International Classification:

A61F 2/38

US Classification:

623 2011

Abstract:

A method of implanting an aggregate joint prosthesis with a side approach to a joint includes exposing a side surface of a joint and positioning a pin member within the joint. Articular surfaces can be drilled and milled, and the prosthesis can be implanted. A set plate can be removed, with the set plate being configured to releasably link at least two components of the aggregate prosthesis.

International Classification:

A61F 2/30

US Classification:

623 1811, 623 1111, 623 1611

Abstract:

Disclosed are embodiments of an improved joint prosthesis that can provide the option to improve initial stability without removing the implant or altering the preparation. Embodiments of improved joint implant components can comprise one or more expandable, hollow segmented posts. Methods of implant fixation are also disclosed. Disclosed methods can provide the opportunity for establishing initial biologic fixation (bone ingrowth), and can also provide an adjunct fixation through injecting cement down the center of the post if initial stability is not achieved or is questionable.

Appl. No.:

12/107070

Inventors:

Slobodan Tepic - Zurich, CH
Randall Acker - Ketchum ID, US

International Classification:

A61F 2/08

US Classification:

623 1314, 623 1311

Abstract:

An interarticular ligament prosthesis is formed from a plurality of high strength high modulus polymeric fibers. The fibers are independent and free from intrinsic inter-fiber shear coupling found in braided or bonded fibers. The ligament prosthesis is installed with tubular, bone screw anchors. The fibers of the ligament prosthesis pass through the central hole of the anchors and are knotted at one end. The exit holes of the anchors include ceramic eyelets with polished edges. The edges are rounded to a defined radius for desired fatigue life of the prosthesis.

Inventors:

Randall Lane Acker - Ketchum ID, US
Gregory Thomas Van Der Meulen - Ketchum ID, US

International Classification:

A61F 2/30

US Classification:

623 1811

Abstract:

A novel and improved retaining member can be used with a joint prosthesis which may be implanted with a minimally invasive surgical technique. The retaining member can be configured to releasably link together two or more components of a joint implant in an orientation suitable for implantation. The retaining member can be removed once the joint implant has been positioned within the implant site.

Appl. No.:

14/936556

Inventors:

Christopher G. Sidebotham - Boonton NJ, US
Gregory Thomas Van Der Meulen - Ketchum ID, US
Randall Lane Acker - Ketchum ID, US

International Classification:

A61B 17/80

Abstract:

A bone plate has a curved elongated body including a first end portion and a second end portion. The first end portion is laterally offset relative to the second end portion, and includes a plurality of screw holes. A first screw hole is defined by the second end portion. Each of the screw holes of the first end portion are laterally offset from a straight line extending in a direction along a length dimension of the bone plate and bisecting the first screw hole of the second end portion, and each of the screw holes of the first end portion are on the same side of the straight line as one another.
