The invention relates to a socket system for a prosthesis. The socket system including a prosthesis socket which has a proximal opening for receiving a residual limb and a distal end and which is made, at least partially, of a first fiber-reinforced plastic. The socket system also includes an adapter element which is arranged on the distal end of the prosthesis socket and is designed in such a manner that a distal prosthesis element can be secured to the adapter element. The adapter element includes a base body which is made, at least partially, of a second fiber-reinforced plastic.

A wrist device for a prosthetic limb is provided. The device (1) comprises a base member (3) connectable to the wearer of the device, and a support member (13) connectable to the limb. The support member (13) is pivotably connected to the base member (3) such that the support member can pivot about a pivot axis (A) relative to the base member. A damping mechanism is located between the base (3) member and the support member (5). The damping mechanism comprises a pinion (47) connected to the support member (5) and rotatable about the pivot axis (A) relative to the base member (3). A rack (35) is engaged with the pinion (47) such that rotational motion of the pinion causes a linear motion of the rack, and at least one biasing member (41) extends between the base member (3) and the rack. The biasing member (41) biases the rack (35) and support member (13) into a neutral position. A prosthetic limb incorporating the wrist device is also provided.

To provide a valve cusp sizer which is small and easy to handle. The present invention relates to a valve cusp sizer 100 for determining the size of a valve cusp depending on the size of a cardiac valve. The valve cusp sizer 100 includes a front surface 10 formed in an arcuate surface form to be abutted against an organism, a back surface 20 positioned on an opposite surface side of the front surface 10, and a pinching portion 30 protruding from the back surface 20. By removing a grip member and a grip member attachment portion from a conventional valve cusp sizer in this manner, and by forming the pinching portion 30 to be held by a clamp, tweezers, or the like, it is possible to dramatically miniaturize the valve cusp sizer while maintaining necessary functions of the valve cusp sizer.

A prosthetic attachment for a prosthetic limb. A base is attached to the prosthetic limb. The base has a magnet that is surrounded by base valleys and base peaks. An attachment piece is attached to the prosthetic attachment. The attachment piece also has a magnet that is surrounded by attachment piece valleys and attachment piece peaks. The magnetic force between the base magnet and the attachment piece magnet attracts the prosthetic attachment to the prosthetic limb so that the base peaks and valleys mates with the attachment piece peaks and valleys for a secure removable attachment. In a preferred embodiment a locking device is used to further secure the prosthetic attachment to the prosthetic limb. In a preferred embodiment the prosthetic attachment is a prosthetic hand and the prosthetic limb is a prosthetic arm.

An attachment system for use with a prosthetic device includes a first component including a first surface, and further including one of a channel and a projection disposed on an opposite side of the first component than the first surface. A second component including a second surface, and including the other of the channel and the projection disposed on an opposite side of the second component than the second surface, the other slidably engaging the channel or the projection to selectively couple the first component and the second component together. One of the first surface and the second surface is operable to be attached to the prosthetic device, and the other is operable to be attached to a sole structure having a ground-engaging surface.

A method and system of choosing a prosthetic liner using cross-references databases which informs a user using a specified interface. Specifically, the method comprises a user accessing a graphical interface wherein amputee attributes are entered in order of (1) level of amputation, (2) residual limb length, (3) activity level, (4) residual limb shape/volume, and (5) clinical conditions with corresponding attribute options. Alternatively, the chosen attributes are (1) class of amputation, (2) residual limb length, (3) body weight, (4) use of the prosthesis, (5) activity level, and 6) uneven paths for knee joints with corresponding attribute options. Alternatively, the chosen attributes are (1) level of amputation, (2) residual limb length, (3) body weight, (4) use of the prosthesis, (5) activity level, and 6) uneven paths for foot joints with corresponding attribute options. These amputee attributes are then cross-referenced against one another and compared to a second database containing liners that correspond to the amputee attributes selected thereby educating the user, generally a prosthetist, on the appropriate liner style for a particular amputee.
