Patent number: 9730814Abstract: A prosthetic knee provides security and stability, particularly to low activity users, household and limited community ambulators, single and/or slow speed ambulators, and those with little voluntary control, while also balancing walking (dynamic) performance for low activity users. The prosthetic knee includes a housing, parallel anterior links, a posterior link, and a chassis. The geometry of the links and their relationship to one another allow for low voluntary control, shortening of mid-swing, which reduces stumbling risk, and geometric stability in stance. The anterior links are particularly oriented, sized and located to provide for stability. The anterior links both extend above the posterior link and substantially below the posterior link. The prosthetic knee includes a locking mechanism arranged to arrest movement of the posterior link. The knee including a locking mechanism connected to the housing and arranged to block rotation of the posterior link.Type: GrantFiled: May 16, 2014Date of Patent: August 15, 2017Assignee: OSSUR HFInventors: Bjorn Omarsson, Sigurdur Gisli Karlsson, Sigurdur Olafsson, Gudlaugur Olafsson, David Landry

Patent number: 8177855Abstract: Embodiments of low cost prosthetic feet include a footplate with a connection mechanism embedded within a first foam element having a first stiffness. A second foam element is bonded to the footplate and has a recess in a proximal surface and a stiffness greater than the first foam element. The second foam element may have a portion extending past the terminal end of the footplate. A cosmesis encloses the components of the prosthetic foot. A third foam element that extends through the cosmesis into the second foam element may be provided. The third foam element may have a higher stiffness than the first and second foam elements.Type: GrantFiled: October 1, 2008Date of Patent: May 15, 2012Assignee: Ossur hfInventors: Sigurdur Asgeirsson, Gudlaugur Olafsson, Gudni Ingimarsson
