Patent number: 7189264Abstract: The present invention relates to a system with modular components for forming a prosthetic limb, wherein the effective length of the limb is adjustable to accommodate changing needs of a particular person. Several modular components are provided, including sleeve and spacer modules. Each sleeve module has a body with a selected length and has two opposed ends that are internally threaded. Each spacer module has a body of a selected length and has two opposed ends that are externally threaded. The modules are usable with existing prosthetic components have respective mating ends. The modules are twistable with respect to each other, which enables the effective length of the prosthetic limb to be adjusted. Further, the modules can be interchanged with modules having a different length, which enables large adjustment capabilities. A fully custom fitted prosthetic limb is therefore achievable without the need to custom make a single component.Type: GrantFiled: February 2, 2004Date of Patent: March 13, 2007Assignee: American Prosthetic Components, Inc.Inventor: Michael J.

Patent number: 6981992Abstract: The present invention has three arcuate prongs that are connected to a hub. The hub has a first end and a second end, and at least one end of the hub is circumferentially continuous. The hub second end is threaded. In one embodiment, the hub has a threaded outer surface. In another embodiment, the hub has a threaded inner surface. The prongs are manipulable, or bendable. Stress developed during manipulation of the prongs does not distort the threaded surface of the hub second end. An additional component can be threadably connected to the threaded surface of the hub second end. The circumferentially continuous portion of the hub acts as a barrier that prevents any excess laminate from contacting and bonding with the threads.Type: GrantFiled: April 9, 2003Date of Patent: January 3, 2006Assignee: American Prosthetic Components, Inc.Inventor: Michael J.
