ACTUATED LEG PROSTHESES FOR AMPUTEES
First Claim
1. A prosthetic/orthotic device comprising:
- at least one device portion;
a joint portion for providing for said at least one device portion to pivot between flexion and extension movements relative to another adjacent device portion or an adjacent limb segment of a user; and
a compliant transmission assembly in operational communication with said joint portion, said compliant transmission assembly comprising a compliant member and a pivot interposed between said compliant member and said joint portion,wherein said compliant member absorbs energy when a torque is applied between said at least one device portion and said another adjacent prosthetic portion or the adjacent limb segment of the user.

Abstract
A prosthetic or orthotic device can include at least one device portion and a joint portion for providing for the at least one device portion to pivot between flexion and extension movements relative to another adjacent device portion or an adjacent limb segment of a user. In some embodiments, a prosthetic or orthotic device can include a compliant transmission assembly in operational communication with the joint portion. The compliant transmission assembly can include a compliant member and a pivot. The pivot can be interposed between the compliant member and the joint portion. In some embodiments, the compliant member absorbs energy when a torque is applied.

10. A prosthetic/orthotic device comprising:
-
at least one device portion and a joint portion for providing for the at least one device portion to pivot between flexion and extension movements relative to another adjacent device portion or an adjacent limb segment of a user; and a compliant transmission assembly comprising a lever for being mounted to the joint portion and a compliant member mountable to the device, wherein said compliant member has a non-linear stiffness such that the compliant member is configured to be stiffer at a first torque value than at a second torque value, wherein said first torque value is larger than said second torque value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
