Abstract: A leadless neurostimulation device including a header unit having at least one primary electrode having a contact surface that defines an external surface on a side of the 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 primary electrode and at least partially surrounds the primary electrode, the dielectric mount being configured to electrically insulate the primary electrode from the outer housing, the dielectric mount being received and fixed within a recessed portion of the outer housing, and a housing having a secondary electrode positioned on the same side of the leadless neurostimulation device as the primary electrode, the 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.

Abstract: Implantable medical devices include circuitry positioned adjacent to header-related structures, rather than having the header and related structures sitting atop the position of the circuitry within a device housing. A circuit board within the device housing may be positioned adjacently to a lead bore of the header. Feedthrough conductors may extend from the circuitry to conductors of the header while being positioned adjacently to the circuit board. Lead frame conductors may extend to the electrical connectors of the lead bores while also being adjacent to the upper portion of the circuitry. Device height may be reduced by having the circuitry be positioned adjacent to one or more of the various header-related structures.

Abstract: Medical devices include a housing that defines both a lead bore and a compartment. A separate housing may be inserted into the compartment where the separate housing may include the electrical circuitry of the medical device such as circuitry that provides stimulation and/or sensing. Electrical conductors interconnect terminals of the separate housing to electrical connectors within the lead bore. The two housings may have different shapes and may be constructed of different materials. The housing that defines the lead bore and compartment may be shaped and sized for a specific implantation site while providing the compartment that is shaped and sized for the separate housing.
