The device includes a joint housing forming a chamber, and the chamber has a first opening. A rotary hub can be disposed within the joint housing and configured to act as the ... 10/05/06 - 20060224248 - Prosthetic knee joint mechanism A prosthetic knee joint mechanism has an hydraulic load-activated knee-stabilizing device for resisting joint flexion. A rotary piston (34) connected to one part of the mechanism is rotatable within a fluid-filled fluid displacement chamber (18) assocciated with another part of the mechanism to drive fluid through a fluid passage which ... 09/21/06 - 20060212130 - Vacuum-assisted prosthetic device A prosthetic device for attachment to a residual limb is provided that includes a socket-forming member configured to receive the residual limb, a first portion, and a second portion that is operatively connected to the first portion and rotationally movable relative to the first portion. The prosthetic device also includes ... 08/24/06 - 20060190093 - Method for controlling a dynamic system A method for providing a controlled force to a dynamic system includes applying a force to a first actuator, transmitting the force from the first actuator to a second actuator through a closed fluid path containing a captured volume of fluid, and providing, via the second actuator, a controlled force ... 08/10/06 - 20060178753 - Magnetorheological fluid compositions and prosthetic knees utilizing same The present invention relates in one embodiment to magnetorheological fluids utilized in prosthetic joints in general and, in particular, to magnetorheological fluids utilized in controllable braking systems for prosthetic knee joints. Preferred magnetorheological fluids of the present invention comprises polarizable iron particles, a carrier fluid, and optionally an additive. Preferred ... 04/20/06 - 20060085082 - Systems and methods of controlling pressure within a prosthetic knee The invention in some embodiments relates to systems and methods of controlling pressure within a prosthetic knee. The knee in one embodiment comprises a flexible diaphragm that substantially prevents or mitigates undesirable pressure build-up in a sealed chamber of the knee. The knee in another embodiment comprises a compressible gas ... 04/06/06 - 20060074493 - Systems and methods of loading fluid in a prosthetic knee The invention in some embodiments relates to systems and methods of loading fluid in a prosthetic knee. A vacuum fill technique is utilized in one embodiment to load magnetorheological fluid within small gaps in a chamber of a prosthetic knee. Advantageously, this allows for an efficient loading scheme thereby desirably ... 03/30/06 - 20060069449 - Dynamic seals for a prosthetic knee The invention in some embodiments relates to a dynamic seal for a prosthetic knee. The dynamic seal in one embodiment is utilized to seal a magnetorheological fluid comprising a liquid and solid particles within a chamber of the knee. The dynamic seal embodiments are specially configured with a pre-loaded tensioned ... 10/27/05 - 20050240282 - Vacuum pump with shock absorption and controlled rotation for prosthetic devices A vacuum pump having shock absorption and controlled rotation for use in an artificial limb. The pump includes a housing having a first chamber, and a shaft configured to be received by and to reciprocate within the first chamber, the housing and shaft forming a pump chamber. A piston may ... ### FreshPatents.com Support |
