Abstract

A patch for a therapeutic electrical stimulation device includes a shoe connected to the first side of the patch, the shoe including a body extending in a longitudinal direction from a first end to a second end, and having first and second surfaces, the first end of the shoe defining at least two ports, and the first surface of the shoe defining a connection member. The patch also includes at least one conductor positioned in the ports of the first end of the shoe. The shoe is configured for sliding insertion into a receptacle defined by a controller so that the conductor is connected to the controller to deliver electrical current from the controller, through the conductor, and to the electrodes, and the connection member is at least partially captured by a detent defined by the controller in the receptacle to retain the shoe within the receptacle.
