Publication number: 20130331951Abstract: A controlled-stretch prosthetic liner comprising a polymeric material covered with at least a stretch-controlling fabric. Certain liner types, such as below knee (BK) liners, may also include a panel of more stretchable fabric so as to prevent any interference with knee flexion. The polymeric material of the liner may also be used to control liner stretch, such as by adding Kevlar pulp or other materials that increase the strength and reduce the elasticity of the polymeric material and/or by reducing the amount of plasticizer(s) present therein. The stretch-controlling fabric, possibly in conjunction with the polymeric material, acts to limit the longitudinal stretch of the liner while not adversely affecting the radial stretch thereof.Type: ApplicationFiled: November 26, 2012Publication date: December 12, 2013Applicant: THE OHIO WILLOW WOOD COMPANYInventor: The Ohio Willow Wood Company

Patent number: 8523951Abstract: A tube-sock shaped polymeric covering for wearing over an amputation stump. The covering has an open end for receiving the amputation stump and a closed end opposite the open end. The covering includes a docking means for attachment of an external device to the covering. The covering may also include one or more areas of reinforcing material that can be present in the form of a strip or rod, for example. The reinforcing material is comprised of a material that is less stretchable than the polymeric material forming the covering, and acts to reduce stretching and/or movement of the covering.Type: GrantFiled: December 22, 2008Date of Patent: September 3, 2013Assignee: The Ohio Willow Wood CompanyInventor: Bruce G.
