A device that is implantable in body tissue of a human or animal. The device is comprised of a header comprising at least one terminal adapted for removable connection to a lead and an open ended case closed by a plate to form a housing. The housing is comprised of a surrounding edge wall joined to a first side wall and a second side wall opposed to the first side wall. At least a first suture port extends through the edge wall and the second side wall but not the first side wall at an upper edge region of the housing. A second suture port may extend through the surrounding edge wall and the second side wall but not the first side wall in a similar manner. A third suture port may extend through the header. The three suture ports may define a triangular attachment configuration.

An implantable stimulator is provided having a substrate comprising a conformable portion with an electrode array, and a pulse generator. A plurality of electrical interconnections are positioned between the surfaces of the substrate. The conformable portion has a thickness equal to or less than 0.5 millimeters. Optionally, one or more encapsulation layers may be provided. Optionally, one or adhesion layers may also be provided comprising a ceramic material.

By providing a more easily patternable substrate, more complicated electrode array configurations may be supported, allowing a higher degree of flexibility to address transverse and/or longitudinal misalignment. By providing a relatively thin implantable electrode array, user comfort may be increased. The one or more adhesion layers improve the performance of the encapsulation.

This document discusses, among other things, systems and methods for delivering electrostimulation to specific tissue of a patient. An example of a system can receive a three-dimensional voxelized model representing a plurality of regions each specified as a target region or an avoidance region. The system includes control circuitry to determine a metric value using the voxelized model. The metric value indicates a clinical effect of electrostimulation on the plurality of regions according to a stimulation current and a current fractionalization. The control circuitry can determine a desired stimulation current that results in a first metric value satisfying a clinical effect condition. The system can generate a stimulation configuration including the desired stimulation current and the current fractionalization corresponding to the first metric value, and deliver tissue stimulation according to the stimulation configuration.

Devices, systems, and techniques are described for use in recharging a power source of a cranially mounted implantable medical device. In one example, a wearable medical device includes a flexible body configured to cover at least a portion of a scalp of a head of a patient. A securing member is connected to the flexible body and configured to extend around a circumference of the head to stabilize the flexible body with respect to the scalp of the patient. A fixation member is configured to mount to a location of the flexible body and couple the flexible body to a recharge coil that is configured to recharge the power source of the cranially-mountable implantable medical device.

An implantable neurostimulator system is disclosed, the neurostimulator system comprising a hollow cylindrical electronics enclosure having a top, a bottom, and a side; a coil extending from a first part of the electronics enclosure; and at least one electrode operatively connected to the electronics enclosure.

A low-profile intercranial device with universal power supply includes a static cranial implant adapted for the selective integration of a functional neurological implant. It also includes a universal power supply having a universal implantable power source with a connector.

A method for programming an electrical stimulation system including at least one implantable electrical stimulation lead including a plurality of electrodes that includes receiving a target and a location of the at least one implantable electrical stimulation lead; receiving at least one stimulation criterion; for each of the at least one stimulation criterion, identifying one or more values of a cost parameter that meet the stimulation criterion, wherein the cost parameter includes a ratio of a cost of stimulating at least one defined region of tissue over a benefit of stimulating a region of the target; and providing at least one of the one or more values of the cost parameter that meet the at least one stimulation criterion to a user or the electrical stimulation system to assist in programming the electrical stimulation system.
