Systems and methods for therapeutic electrical stimulation
View Patent ↗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.
1. A system for delivering therapeutic electrical stimulation, the system including a controller comprising:
a power source;
an electrical signal generator powered by the power source and configured to generate an electrical signal; and
a receptacle comprising at least one conductor, wherein the conductor is configured to couple to the electrical signal generator to receive the electrical signal, wherein the receptacle is configured to receive a portion of a patch so as to electrically couple a portion of the patch to the conductor, wherein the receptacle comprises a detent configured to capture the portion of the patch to retain the portion of the patch within the receptacle.
2. The system of claim 1 , further comprising:
the patch for a therapeutic electrical stimulation device, the patch comprising an insulating layer having a first side and a second side, the patch further comprising at least two electrodes adjacent the second side of the patch; and
a shoe configured for configured for insertion into the receptacle and connection to the first side of the patch, the shoe comprising at least two conductors, wherein each conductor configured for electrical coupling to one of the electrodes.
3. The system of claim 2 , wherein the shoe comprises a first portion that is normal to the first side of the insulating layer and a second portion that is angled from the first portion.
4. The system of claim 3 , wherein the second portion is angled about ninety degrees from the first portion.
5. The system of claim 4 , wherein the shoe includes a member that is partially captured by the detent defined by a controller in the receptacle to retain the shoe within the receptacle.
6. The system of claim 5 , wherein the controller operates to generate electrical signals for at least one action selected from the group consisting of transcutaneous electrical nerve stimulation, drug delivery, iontophoresis therapy, edema reduction, wound healing, and interferential current therapy.
