Abstract: A burr hole plug includes a base having a flange configured to rest on the skull of a patient and a sidewall configured to extend into a burr hole. The burr hole plug also includes a flexible cover configured to be disposed entirely over, and coupled to, the base. The flexible cover includes a skirt to fit around an outer perimeter of the base and a rim that fits inside the sidewall of the base. Between the skirt and the rim is an inset region having a shape corresponding to a shape of the flange of the base. Alternatively or additionally, the burr hole plug may include two lead retention members, each of the lead retention members including a lead engagement surface to engage and hold a lead; and a locking member for locking the two lead retention members in the base.

Abstract: An electrical stimulation lead latching kit includes a connector having a housing that defines a lead lumen and a latching lumen that at least partially intersects the lead lumen; and a latching device including a latching pin, a handle, and an attaching element that attaches the latching pin to the handle. The latching pin has a longitudinal surface and is configured for insertion into the latching lumen, and the attaching element is configured to enable the latching pin to detach from the handle when the latching pin is in the latching lumen. When the latching pin is positioned in the latching lumen and a portion of an electrical stimulation lead or lead extension is positioned in the lead lumen, the longitudinal surface of the latching pin engages the electrical stimulation lead or lead extension to latch the electrical stimulation lead or lead extension to the connector.

Abstract: An implantable medical device (IMD) includes a housing that is formed of a biocompatible material such as silicone. The housing includes integral contact receptacles that house individual contacts, which contacts are electrically connected to electrical circuitry within a main interior cavity of the housing. The integral contact receptacles receive electrode leads, and the contacts are aligned with electrode terminals on the proximal end of the electrode leads, which establishes an electrical connection between the electrical circuitry and electrodes at the distal end of the leads. The housing is filled with a silicone gel such as a tacky diphenyl silicone gel. The silicone gel provides electrical, mechanical, and thermal insulation, and prevents the ingress of bodily fluids when the IMD is implanted.

Abstract: A connector for an implantable electrical medical device includes a connector lumen defined in an elongated connector housing and adapted for receiving a portion of a lead. Connector-contact assemblies are disposed in the connector lumen and adapted to couple to terminals of the lead when the lead is received by the connector lumen. Each of the connector-contact assemblies includes a contact body. An inner surface of the contact body defines an open center portion. A first base is disposed along a first end of the contact body, and a second base is disposed along an opposing second end of the contact body and is coupled to the first base. Biasing members are attached to the first base and extend towards the second base. The biasing members are not attached to the second base. When the lead is received by the connector lumen the biasing members physically contact the received lead.

Abstract: A convertible implantable stimulator that provides electrical stimulation therapy during an extended trial stimulation period (or permanently, if desired) in a fully implanted solution is disclosed. The convertible implantable stimulator preferably does not include an internal power supply and is therefore continuously powered by an external charger, such as a powering patch, in a first mode of operation. If the convertible implantable stimulator is determined to be effective and a patient desires more traditional stimulation therapy, a separate power supply module can subsequently be implanted and connected to the convertible implantable stimulator to provide power to the stimulator in a second mode of operation.

Abstract: A segmented-contact set of a lead includes segmented contacts extending around less than an entire circumference of the lead and not in electrical contact with one another. The segmented-contact set includes first and second segmented contacts that each include a stimulation portion and a retention member. The stimulation portion has a stimulation surface exposed along an outer surface of the lead. The retention member is coupled to the stimulation portion. The stimulation portion and the retention member collectively form a loop of material that extends around a center transverse axis of the lead beneath the outer surface. A first insulating member is disposed between the stimulation portion of the first segmented contact and the retention member of the second segmented contact. A second insulating member is disposed between the stimulation portion of the second segmented contact and the retention member of the first segmented contact.
