Inhibition of implant migration
First Claim
1. Apparatus, comprising:
- an electrostimulator implant, comprising;
an implant body, the implant body having a longitudinal axis,first and second electrodes, disposed on respective first and second portions of the implant body;
circuitry, disposed inside the implant body; and
a mesh;
configured to serve as an anchor of the implant,disposed circumscribing entirely around a third portion of the implant body that is longitudinally between the first and second portions of the implant body, andhaving a first end and a second end, each of the ends being fixedly attached to respective first and second sites of the implant body, the respective sites being longitudinally between the first and second electrodes, anda percutaneously-advanceable delivery tool comprising a needle,wherein;
the implant is disposed within the needle;
the needle is configured for intramuscular injection;
the tool is configured to inject the electrostimulator implant by applying a longitudinal force, within the needle, to the implant, causing the implant to become exposed from the needle, and to become implanted within solid tissue of a subject such that the mesh is in circumferential contact with solid tissue surrounding the third portion;
the mesh is configured to inhibit movement of the implant within the solid tissue by;
(i) initially providing mechanical anchoring, and(ii) promoting tissue growth thereupon; and
the circuitry is configured to neurostimulate the subject by driving the electrodes to apply stimulatory current to the solid tissue.

Abstract
An electrostimulator implant comprises (i) an implant body, the implant being injectable into tissue of a subject along a longitudinal axis of the implant body, (ii) first and second electrodes, disposed on respective first and second portions of the implant body; (iii) circuitry, disposed inside the implant body, and configured to drive the electrodes to apply current to the tissue; and (iv) a mesh. The mesh is configured to serve as an anchor of the implant, is disposed over a third portion of the implant body that is longitudinally between the first and second portions of the implant body, and has a first end and a second end. Each of the ends is fixedly attached to respective first and second sites of the implant body, the respective sites being longitudinally between the first and second electrodes.
