20090030531 | PROSTHETIC FOOT - 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. | 01-29-2009 |

20120185060 | Casting Liner, and Method and Kit for Using the Same - A tubular casting liner for forming a definitive prosthetic socket includes an outer layer defining first and second surfaces and at least one polymeric layer having first and second surfaces. The first outer layer surface continuously defines at least a portion of the exterior surface of the casting liner, and the at least one polymeric layer first surface is secured to the second surface of the outer layer. A ratio of thickness of the at least one polymeric layer at the distal end area relative to the proximal end area is at least 3:1. The casting liner has a substantially straight profile, wherein a diameter d | 07-19-2012 |
20130073056 | DORSI-PLANTAR PROSTHETIC ANKLE MODULE - An ankle module for a prosthetic foot can have an adapter portion pivotally coupled to a base portion. The base portion can be coupled to the prosthetic foot. The adapter portion can have a coupling member that removably couples the prosthetic foot to a prosthetic pylon or socket. The adapter portion can also have cylinders housing pistons slidably displaceable within the cylinders. An actuator is selectively actuatable to place the cylinders in fluid communication, allowing a fluid to flow between the cylinders as an angular position of the adapter portion is adjusted relative to the base portion, thereby adjusting the dorsi-plantar position between the adapter portion and the base portion of the ankle module. The actuator can be selectively actuatable to fluidly isolate the cylinders from each other so that the angular position of the adapter portion relative to the base portion remains substantially fixed. | 03-21-2013 |
