Patent ID: 7377944

Claim:
A socket liner for receiving a limb of an amputee, the socket liner comprising: a liner in the shape of a tubular body having a longitudinal axis that extends from a closed distal end of the liner to an open proximal end of the liner, wherein: the liner is generally symmetrical about the longitudinal axis, the liner has an inner and an outer layer, and the outer layer serves to provide an interface between the inner layer and a socket; and a physiological sensor configured to receive data from a limb regarding its physiological characteristics; the sensor being positioned in a channel formed between the liner inner layer and the liner outer layer; the sensor including an extending portion that extends outwardly from the open proximal end of the liner in a generally longitudinal direction; the sensor being in communication with a transmitter; and the transmitter configured to send data to a receiver to allow an end user to analyze the physiological characteristics of the limb.
