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.

Claims

1. A method of delivering therapeutic electrical stimulation, the method comprising:

positioning a channel formed by a shoe of a patch with a railway formed in a receptacle of a controller;

advancing the controller in a first direction along the railway toward the patch to insert the shoe of the patch into the receptacle of the controller; and

allowing a member of the shoe to engage a detent formed by the controller to capture the shoe within the controller and to form an electrical connection between the controller and the patch.

2. The method of claim 1, further comprising:

moving the member in a first direction to uncouple the detent from the member of the shoe; and

moving the shoe in a second direction opposite to the first direction to remove the patch from the controller.

3. The method of claim 1, further comprising advancing the controller in a second direction to cause the controller to engage with the shoe.

4. The method of claim 2, wherein the second direction is substantially perpendicular to the first direction.

5. The method of claim 1, further comprising:

operating the therapeutic electrical stimulation device in a first mode by executing a first firmware algorithm;

downloading a second firmware algorithm;

installing the second firmware algorithm onto the therapeutic electrical stimulation device; and

executing the second firmware algorithm to operate the therapeutic electrical stimulation device in a second mode.

6. The method of claim 5, wherein the first mode provides a transcutaneous electrical nerve stimulation therapy, and wherein the second mode is different than the first mode.

7. The method of claim 5, wherein the second mode provides an iontophoresis therapy.

8. The method of claim 5, further comprising purchasing the second firmware algorithm before downloading the second firmware algorithm.

9. The method of claim 5, further comprising accessing a patient interface of a web server prior to downloading the second firmware algorithm.

10. The method of claim 1, further comprising positioning the patch in a garment configured to be worn by a user.
