1. A disposable external trial electrical stimulator comprising:
- a therapy delivery module configured to deliver electrical stimulation via at least one percutaneous stimulation lead configured to be connected to the disposable external trial stimulator;
a lead coupler configured to connect a plurality of types of percutaneous stimulation leads configured to be coupled to the disposable trial stimulator directly to the disposable external trial stimulator without any intervening lead connection devices, the at least one percutaneous stimulation lead configured to be connected to the disposable external trial stimulator being one type of percutaneous stimulation lead of the plurality of types of percutaneous stimulation leads;
a lead coupler door comprising a portion of an exterior wall of the disposable external trial stimulator and configured to expose the lead coupler when opened; and
a processor configured to;
control the therapy delivery module to deliver the electrical stimulation via the at least one percutaneous stimulation lead;
automatically detect, when the at least one percutaneous stimulation lead is connected to the disposable external trial stimulator, the at least one percutaneous stimulation lead as the one type of percutaneous stimulation lead instead of another type of percutaneous stimulation lead of the plurality of types of percutaneous stimulation leads;
automatically, based on the detected one type of percutaneous stimulation lead connected to the trial stimulator, perform one or more of the following;
(1) limit one or more stimulation programming options available to a programmer, (2) limit one or more stimulation parameter values, or (3) select one or more different programs according to stimulation that the therapy delivery module can deliver via the detected one type of percutaneous stimulation lead;
detect when the lead coupler door is open; and
responsive to detecting that the lead coupler door is open, automatically, and without user interaction, control the therapy delivery module to cease delivery of stimulation,wherein the disposable external trial stimulator is sterilized.

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.

19. A method comprising:
-
implanting a percutaneous stimulation lead configured to be connected to a disposable external trial stimulator to deliver stimulation to a target tissue location; connecting the percutaneous stimulation lead directly to the disposable external trial stimulator via a lead coupler integral with the disposable external trial stimulator, wherein the lead coupler is configured to connect a plurality of types of percutaneous stimulation leads configured to be coupled to the disposable trial stimulator directly to the disposable external trial stimulator without any intervening lead connection devices, the percutaneous stimulation lead configured to be connected to the disposable external trial stimulator being one type of percutaneous stimulation lead of the plurality of types of percutaneous stimulation leads; automatically detecting, by a processor of the disposable external trial stimulator and when the percutaneous stimulation lead is connected to the disposable external trial stimulator, the percutaneous stimulation lead as the one type of percutaneous stimulation lead instead of another type of percutaneous stimulation lead of the plurality of types of percutaneous stimulation leads; automatically, by the processor of the disposable external trial stimulator and based on the detected one type of percutaneous stimulation lead connected to the trial stimulator, performing one or more of the following;
(1) limiting one or more stimulation programming options available to a programmer, (2) limiting one or more stimulation parameter values, or (2) selecting one or more different programs according to stimulation that the external trial stimulator can deliver via the detected one type of percutaneous stimulation lead;programming, with an electronic programming device, the disposable external trial stimulator to deliver stimulation via the percutaneous stimulation lead, wherein the electronic programming device is configured to wirelessly communicate with the disposable external trial stimulator; delivering stimulation to the target tissue location via the percutaneous stimulation lead with the disposable external trial stimulator for a trial period of time; detecting, by the processor of the disposable external trial stimulator, that a lead coupler door is open, the lead coupler door comprising a portion of an exterior wall of the disposable external trial stimulator and configured to expose the lead coupler when opened; responsive to detecting that the lead coupler door is open, automatically, by the processor of the disposable external trial stimulator and without user interaction, controlling the disposable external trial stimulator to cease delivery of stimulation; and disposing of the disposable external trial stimulator after expiration of the trial period of time. - View Dependent Claims (20, 21, 22, 23, 24, 25)
