1. A system for securing a disposable trial stimulator to a body of a patient, the system comprising:
- a patch comprising a first major surface at least partially covered with an adhesive configured to adhere the patch to the body of the patient; and
a holster connected to a second major surface of the patch, wherein the holster is configured to receive the trial stimulator, a portion of the holster configured to be disposed at least partially around a perimeter of the trial stimulator to hold the trial stimulator within the holster, wherein the holster comprises;
a first planar major wall having one or more edges;
one or more minor walls, each of which protrudes perpendicular to the first major planar wall from a respective edge of the one or more edges, wherein at least one minor wall of the one or more minor walls defines one or more slots; and
a second planar major wall defining one or more grooves corresponding to respective slots of the one or more slots, wherein the second planar major wall is connected to and offset from the first planar major wall by the one or more minor walls, and wherein the second planar major wall is parallel to the first planar major wall and perpendicular to the one or more minor walls.

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.

18. A method of securing a disposable trial stimulator to a body of a patient, the method comprising:
-
implanting a stimulation lead to deliver stimulation to a target tissue location; adhering a first major surface of a patch at least partially covered with an adhesive to the body of the patient, wherein a holster is connected to a second major surface of the patch, and wherein the holster is configured to receive the trial stimulator; inserting the trial stimulator into the holster so that a portion of the holster is disposed at least partially around a perimeter of the trial stimulator to hold the trial stimulator within the holster, wherein the holster comprises; a first planar wall having one or more edges; one or more minor walls, each of which protrudes perpendicular to the first major planar wall from a respective edge of the one or more edges, wherein at least one minor wall of the one or more minor walls defines one or more slots; and a second planar major wall defining one or more grooves corresponding to respective slots of the one or more slots, wherein the second planar major wall is connected to and offset from the first planar major wall by the one or more minor walls, and wherein the second planar major wall is parallel to the first planar major wall and perpendicular to the one or more minor walls; and connecting the stimulation lead to the trial stimulator. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
