Classification: CPC A | IPC A

Claim 14:
15. A leadless neurostimulation device comprising:
a header unit comprising:
at least one primary electrode having a contact surface that defines an external surface on a side of the leadless neurostimulation device;
an outer housing that forms a side of the header unit opposite of the contact surface of the primary electrode; and
a dielectric mount that receives at least a portion of the at least one primary electrode and at least partially surrounds the at least one primary electrode, the dielectric mount being configured to electrically insulate the at least one primary electrode from the outer housing, the dielectric mount being received and fixed within a recessed portion of the outer housing,
wherein the dielectric mount defines a channel between the outer housing and the dielectric mount, the channel configured to receive a medical adhesive therein to fix the outer housing to the dielectric mount,
wherein the primary electrode comprises an interior surface that defines an interlocking structure with the dielectric mount;

a housing comprising a secondary electrode positioned on the same side of the leadless neurostimulation device as the at least one primary electrode, the at least one primary electrode and the secondary electrode being configured to transmit an electrical stimulation signal therebetween to provide electrical stimulation therapy to a tibial nerve of a patient;
at least one lead pin configured to pass through a mounting plate and connect to processing circuitry and components contained in the housing configured to transmit the electrical stimulation signal between the one or more primary electrodes or secondary electrodes to provide electrical stimulation therapy to the tibial nerve, wherein the primary electrode is electrically coupled to the lead pin; and
a mounting plate, wherein the housing is coupled to a first side of the mounting plate and the header unit is coupled to a second side of the mounting plate,
wherein the at least one primary electrode and the secondary electrode define a separation distance of about 10 mm to about 20 mm, and
wherein the leadless neurostimulation device defines a total volume of about 1.5 cubic centimeters (cc) to about 3.5 cc.
