1. Apparatus comprising an implant, the implant comprising:
- a rod-shaped housing, having a distal half and a proximal half, and configured to be injected distally into tissue of a subject;
a first electrode, configured to function as a cathode on the distal half of the housing;
an anchor configured to protrude from the proximal half of the housing, no anchor being configured to protrude from the distal half of the housing;
a second electrode, configured to function as an anode, and disposed at a site of the housing that is distal to the anchor and proximal from the cathode; and
circuitry disposed within the housing, configured to configure the first electrode to function as the cathode, to configure the second electrode to function as the anode, and to drive a current between the cathode and the anode,wherein the anchor comprises a tether that has;
a distal end coupled to the housing, and configured to remain coupled to the housing during and after injection of the housing,a proximal end, configured to remain outside the subject during and after the injection of the housing, anda distal portion that comprises the distal end, and is configured to promote tissue growth that adheres the distal portion to the tissue, thereby inhibiting movement of the housing with respect to the tissue.

14. A method, comprising:
-
injecting, distally into tissue of a subject, a rod-shaped housing of an implant, wherein; the rod-shaped housing has a distal half and a proximal half, the implant comprises; a first electrode, configured to function as a cathode on the distal half of the housing; an anchor configured to protrude from the proximal half of the housing, no anchor being configured to protrude from the distal half of the housing; a second electrode, configured to function as an anode, and disposed at a site of the housing that is distal to the anchor and proximal from the cathode; and circuitry disposed within the housing, configured to configure the first electrode to function as the cathode, to configure the second electrode to function as the anode, and to drive a current between the cathode and the anode, wherein; the anchor comprises a tether that has; a distal end coupled to the housing, a proximal end, and a distal portion that comprises the distal end, injecting the housing comprises; injecting the housing while (i) the distal end of the tether remains coupled to the housing, and (ii) the proximal end of the tether remains disposed outside of the subject, and leaving (i) the distal end of the tether coupled to the housing, and (ii) the proximal end of the tether outside of the subject, and the distal portion of the tether is configured to promote tissue growth that adheres the distal portion to the tissue, thereby inhibiting movement of the housing with respect to the tissue.
