Abstract
A trial stimulation system includes a disposable trial electrical stimulator that, in some examples, is sterilized for a single use in a stimulation trial of one patient. Additionally, systems for securing a disposable trial stimulator to the body of a patient are described, which may function to improve the durability of the system during the trial period and reduce the risk of damage or malfunction to the system due to lead/electrode dislocation and/or off-label uses like showering or bathing with the trial stimulator still secured to the body.
Claims14
A disposable electrical stimulator comprising:
- a housing;
- a stimulation engine within the housing and configured to deliver electrical stimulation via one or more electrodes carried by at least one percutaneous stimulation lead connectable to the disposable electrical stimulator;
- and
- one of a button, a rocker switch, a slider switch, or a rotary dial switch as a single user interface integral with the disposable electrical stimulator, wherein the one of the button, the rocker switch, the slider switch, or the rotary dial switch is configured to cause the disposable electrical stimulator to be capable of wireless communications with an electronic programming device configured to program the disposable electrical stimulator and to turn off stimulation being delivered by the disposable electrical stimulator.
A medical system comprising:
- an external disposable electrical stimulator comprising:
- a housing;
- a battery;
- a stimulation engine within the housing and configured to generate an electrical signal for stimulation therapy, wherein the stimulation engine is configured to generate the electrical signal having pulses comprising a pulse rate between 0.5 Hz and 1200 Hz and a pulse width between 10 microseconds and 5000 microseconds, wherein the stimulation engine is configured generate the electrical signal as a current controlled electrical signal, and wherein the external disposable electrical stimulator is configured to be disposed after a single stimulation trial with one patient;
- at least one percutaneous stimulation lead configured to be connected to the external disposable electrical stimulator;
- and
- an electronic programming device configured to wirelessly communicate with the external disposable electrical stimulator to program the disposable electrical stimulator to deliver the electrical signal as the stimulation therapy via the at least one percutaneous stimulation lead, wherein the electronic programming device comprises a user interface having at least a first button and one or more lights,
- wherein the external disposable electrical stimulator comprises one of a second button, a rocker switch, a slider switch, or a rotary dial switch as a user interface integral with the external disposable electrical stimulator, and wherein the one of the second button, the rocker switch, the slider switch, or the rotary dial switch is configured to cause the external disposable electrical stimulator to be capable of wireless communications with the electronic programming device and to turn off stimulation being delivered by the external disposable electrical stimulator.
