International Classification:

A61F 2/48
A61F 2/78
A61F 2/80
A61F 2/60

US Classification:

623 24, 623 33, 623 34, 623 35, 623 36

Abstract:

Evacuation devices for evacuating the socket of a prosthetic limb, and prosthetic limb systems employing such vacuum devices. The evacuation devices each preferably include at least an electrically powered vacuum pump and a power source. Such evacuation devices can be attached at various locations on or in a prosthetic limb. Because the electrically powered pump does not require manual manipulation to create vacuum, it is substantially easier to use than a manual pump. Due to the small size and small power source required by such an electrically powered pump, an evacuation device may be readily incorporated into a prosthesis.

International Classification:

A61F 2/48
A61F 2/78
A61F 2/60

US Classification:

623 24, 623 33

Abstract:

A prosthetic device and prosthetic assembly operative to evacuate an interior of a prosthetic socket, and control systems for use therewith. The prosthetic device and prosthetic assembly employ evacuation devices for evacuating the socket. The evacuation devices preferably include at least an electrically powered vacuum pump and a power source, and are adapted for mounting to a universal adapter that is installed to the distal end of a prosthetic socket. Associated control systems may be of various design and may employ wired or wireless communication. When wireless communication is employed, a hand held controller may be used to remotely control operation of the evacuation device.

International Classification:

A61F 2/80
A61F 2/48

US Classification:

623 34, 623 24, 623 38

Abstract:

Prosthetic devices having vacuum components operative to evacuate the interior of a prosthetic socket thereof, and control systems for use therewith. The evacuation devices preferably include at least an electrically powered vacuum pump and associated power source, and a vacuum accumulator connected to the vacuum pump. Associated control systems may be of various designs and may employ wired or wireless communication. Control of an evacuation device may be based on vacuum level, residual limb volume, residual limb motion, user activity level or other device parameters.

Assignee:

The Ohio Willow Wood Company - Mt. Sterling OH

International Classification:

A61F 2/80

US Classification:

623 34

Abstract:

A prosthetic suspension sleeve having reinforcement that prevents or minimizes damage to the suspension sleeve, particularly as a result of abrasion, puncture, or an impact with another object during use. The reinforcement may be selectively located along one or more interior, exterior, or interior and exterior areas of a suspension sleeve. The reinforcement material may be comprised of one or more materials that preferably exhibit resistance to cuts, tears, punctures and/or other damage. In an alternative embodiment, reinforcement may be provided by mixing one or more reinforcing materials into the polymeric material of the suspension sleeve. Combinations of different reinforcement types may be employed.

US Classification:

623 36

Abstract:

A multi-layer prosthetic liner having an inner polymeric material layer surrounded by an outer polymeric material layer. The outer polymeric material layer is dissimilar to the inner polymeric material layer. A tying layer may reside between the inner polymeric material layer and the outer polymeric material layer. Any embodiment of the liner may be wholly or partially covered on its exterior with a material that exhibits low-friction and/or wicking characteristics.

International Classification:

A61F 2/80

US Classification:

623 36

Abstract:

Prosthetic socket sealing systems and methods of use. Embodiments of the present invention include various combinations of sealing elements that are associated with a rigid prosthetic socket and act to seal the socket interior against air intrusion or escape via the open proximal end thereof. The socket interior may thus be evacuated for purposes of vacuum suspension or otherwise.

Assignee:

Danninger Medical Technology, Inc. - Columbus OH

International Classification:

A61H 102

US Classification:

128 26

Abstract:

A continuous passive motion device is provided which imparts a reciprocating spiral motion to one or more fingers of a user. The device can also be adapted for use with a thumb. The motion is achieved by linking a rotary motion of the device to a linear motion with respect to the device of a linear actuator.
