20100004757 | SMOOTH ROLLOVER INSOLE FOR PROSTHETIC FOOT - A prosthetic foot includes a foot member, a heel member operatively coupled to the foot member. At least one of the heel member and foot member define an arch portion that faces a support surface that the prosthetic foot contacts during use. An insole member contacts said arch portion, the insole member configured to facilitate a rollover of the prosthetic foot in at least one of a lateral-medial and a medial-lateral direction during ambulation. | 01-07-2010 |
20100152865 | NOISE REDUCTION DEVICE FOR ARTICULATING JOINT, AND A LIMB SUPPORT DEVICE HAVING THE SAME - An articulating connection or joint for a limb support device having a first support member and a second support member pivotably couples together the first support member and the second support member. The articulating connection can include one or more first articulating connection member, or load-bearing pin, and one or more second articulating connection member, or bushing, disposed about the first and second support members. The load-bearing pin is coupled to one of the support members and the bushing is coupled to another of the support members. The bushing is configured to rotatingly receive the load-bearing pin and interacts with an actuation member configured to apply a force on the load-bearing pin to eccentrically align the load-bearing pin relative to the bushing so that the load-bearing pin continuously follows and contacts a bearing surface of the bushing during use of the limb support device, thereby inhibiting noise generation from the interaction of the bushing and load-bearing pin. | 06-17-2010 |
20110264239 | SUSPENSION LINER SYSTEM WITH SEAL - A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, and having outer and inner surfaces. The liner sleeve includes an elongate, generally conical body portion formed from at least one material segment defining the liner outer surface. The at least one material segment being at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas. The liner sleeve includes a layer of polymeric material disposed on the at least one material segment and defining the liner sleeve inner surface, and a plurality of resilient seal elements protruding radially from the liner sleeve outer surface. The plurality of seal elements extend around at least one peripheral portion of the liner body portion. A pair of opposed annular recesses may be adjacently located above and below each of the at least one seal element. | 10-27-2011 |
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 |
20130184836 | SUSPENSION LINER SYSTEM WITH SEAL - A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, and having outer and inner surfaces. The liner sleeve includes an elongate, generally conical body portion formed from at least one material segment defining the liner outer surface. The at least one material segment being at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas. The liner sleeve includes a layer of polymeric material disposed on the at least one material segment and defining the liner sleeve inner surface, and a plurality of resilient seal elements protruding radially from the liner sleeve outer surface. The plurality of seal elements extend around at least one peripheral portion of the liner body portion. A pair of opposed annular recesses may be adjacently located above and below each of the at least one seal element. | 07-18-2013 |
20130211544 | VACUUM ASSISTED SUSPENSION SYSTEM - A vacuum assisted suspension system is used to increase or maintain negative pressure or vacuum in a sealed socket cavity as a socket and prosthetic limb attachment mechanism. The system includes a vacuum pump having a housing that defines an enclosed space to receive a fluid. At least one wall of the housing and at least one movable wall define a fluid compartment. The system includes a compression transfer element connected to the at least one movable wall and connected to a prosthetic foot. The compression transfer element causes the at least one movable wall of the fluid compartment to move and increase the volume of the fluid compartment in response to a compressive force on the prosthetic foot to draw in fluid from the prosthetic socket. In the absence of a compressive force, the volume of the fluid compartment decreases thereby expelling fluid out of the fluid compartment. | 08-15-2013 |
20140039642 | PROSTHETIC ANKLE MODULE - A prosthetic ankle module allows for translational and/or rotational movement of a prosthetic foot relative to an adapter. The ankle module can include a four-bar linkage assembly. Links of the linkage assembly can be arranged in various configurations, e.g., parallel or non-parallel and having equal or non-equal lengths, to provide different functions and benefits, e.g., dorsiflexion, plantar flexion, vertical shock absorption, inversion, eversion, and/or rotation about the sagittal axis. Other types of linkage assemblies are also possible. A prosthetic foot can further include a support spring to limit the range of motion of the adapter in use. | 02-06-2014 |
