Patent number: 7947085Abstract: Evacuation devices for evacuating the socket of a prosthetic limb, and prosthetic limb systems employing such vacuum devices. The evacuation devices each preferably include at least an electrically powered vacuum pump and a power source. Such evacuation devices can be attached at various locations on or in a prosthetic limb. Because the electrically powered pump does not require manual manipulation to create vacuum, it is substantially easier to use than a manual pump. Due to the small size and small power source required by such an electrically powered pump, an evacuation device may be readily incorporated into a prosthesis.Type: GrantFiled: June 12, 2006Date of Patent: May 24, 2011Assignee: The Ohio Williow Wood CompanyInventors: Wilbur A.

Patent number: 7563288Abstract: A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. A substantially hollow prosthetic foot connection component includes a receiving cavity for receiving a portion of a lower leg connection component. A retainer or retainer assembly is preferably installed into the receiving cavity to help retain the lower leg connection component therein. Once the necessary components are in place, the remainder of the receiving cavity is substantially filled with an elastomeric material. An external bearing may reside atop the elastomeric material and act in conjunction with the elastomeric material to control ankle flexion.Type: GrantFiled: June 1, 2006Date of Patent: July 21, 2009Assignee: The Ohio Willow Wood CompanyInventors: Jeffrey L.

Patent number: 7162322Abstract: A system and method for manufacturing a custom prosthetic liner. The system may include a shape capture device for capturing the shape of a residual limb. The captured shape may be used to generate a 3-dimensional electronic liner model using a processor and specialized software. A 3-dimensional electronic model of the residual limb may also be produced. Preferably, an interface is provided that allows a user of the system to alter the shape and/or size of the 3-dimensional model(s) to allow the subsequently-produced liner to accommodate particular features of the residual limb. Data associated with at least the resulting 3-dimensional liner model is provided to a manufacturing facility equipped to produce a custom liner therefrom. The data may be remotely transmitted to the manufacturing facility. A positive likeness of the residual limb is created from the data associated with the 3-dimensional model(s), and is subsequently used as a mold core in the liner molding process.Type: GrantFiled: November 28, 2003Date of Patent: January 9, 2007Assignee: The Ohio Willow Wood CompanyInventors: Robert E.

Patent number: 7112227Abstract: A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. In one embodiment, a prosthetic foot connection component is connected to a prosthetic lower leg connection component only by means of an elastomeric material, thereby allowing for multi-axis movement of the ankle without requiring direct contact between the two components. In other embodiments of the ankle, a prosthetic foot connection component may be mechanically connected to a prosthetic lower leg connection component. However, the design of the mechanical connection and the use of an elastomeric material casing allows for movement of the ankle without surface-to-surface sliding contact between the two components. Compression of the elastomeric material, as well as one or more mechanical stops may be used to control and limit movement of the ankle.Type: GrantFiled: February 3, 2004Date of Patent: September 26, 2006Assignee: The Ohio Willow Wood CompanyInventors: Jeffrey L. Doddroe, Robert E. Arbogast, James M. Colvin, James W. Capper
