In some examples, a burr hole cap assembly includes one or more markers that indicate a rotational orientation of a therapy delivery member relative to the burr hole cap assembly, where the therapy delivery member extends through an opening defined by the burr hole cap assembly. In addition, in some examples, the burr hole cap assembly includes a feature that indicates the rotational orientation of the therapy delivery member after the therapy delivery member is implanted in the patient. The feature can include the one or more markers in some examples.

An implantable electrode paddle is adapted to receive an electrical signal from a medical device and generate an electrical field to stimulate selected body tissue. The paddle includes a housing including walls that define an interior space and a plurality of windows formed through at least a first one of the walls for transmitting the electrical field to the body tissue, an electrode array including a plurality of electrode groups, each electrode group including at least two electrodes individually secured in a respective window and spaced between about 0.1 mm and about 10 mm apart, and a plurality of wires, each of the wires being coupled to a respective electrode and routed within the interior space to receive the electrical signal. A lead assembly and an implantable medical device can include the paddle.

Methods and apparatus for anchoring an elongate medical device within a body portal, for example, a stimulation lead in a cranial burr hole, employ a securing element attached to a plate member, which may be held over a body portal by a base ring. The securing element includes a spring member and an engagement surface; a retaining member holds the engagement surface, spaced apart from a side of a slot of the plate member, in an open position, against a bias of the spring member. In the open position, the device may be received between the engagement surface and the side of the slot, through an opening of the slot. Disengaging the retaining member releases a moveable portion of the spring member to move the engagement surface toward the side of the slot and into a closed position, at which the inserted device is anchored. The anchored device may be routed through one of a plurality of base ring channels.

Medical system lead adapters distribute stimulation signals from a port of a medical device to both a primary medical lead and a secondary medical lead. The lead adapters provide for the selectable bridging of secondary lead contacts to thereby provide for customized stimulation patterns. The lead adapters may include a primary lead connector, a secondary lead connector, and a pin connector. A pin is selected to provide a particular stimulation pattern for the secondary lead and is inserted into the pin connector to thereby bridge together contacts of the pin connector that are also connected to contacts of the secondary lead connector.

Medical devices and systems provide for detection of proper lead insertion by monitoring for electrical continuity between adjacent electrical contacts. The electrical contacts are spaced so that an electrical connector of a medical lead being inserted will span the distance between the electrical contacts and thereby maintain a physical connection with both electrical contacts at one time. Upon the medical device detecting that continuity is achieved between the adjacent electrical contacts, the medical device may provide an indication such as a visual and/or audible cue to a clinician who is inserting the lead and/or by providing a telemetry signal to an external device such as a programmer so that the programmer may then provide a visual and/or audible cue to a technician operating the programmer.

An adapter for coupling a pair of implantable neurostimulator lead extension plugs to a connector port of a neurostimulator device includes a connector coupled to a first end of an elongate body and a flexible bifurcation member coupled to a second end of the elongate body, wherein the bifurcation member includes a first branch, to which a first housing, having first and second ports, is coupled, and a second branch, to which a second housing, having first and second ports, is coupled. Openings of the first and second ports of each housing provide for side-by-side insertion of first and second connector terminals of one of the lead extension plugs. Contacts within each port provide for electrical coupling with corresponding contacts of the connector terminals of the plug, and are coupled to corresponding contacts of the adapter connector via conductors extending within the elongate body between the corresponding housing and connector.

An adapter for coupling a plug of an implantable neurostimulator lead extension to a connector port of a neurostimulator device includes an elongate body, a connector including a plurality of contacts coupled to a first end of the elongate body, and a housing including at least two ports coupled to a second end of the elongate body. The adapter connector contacts provide for electrical coupling within the device port, and the adapter housing ports are arranged to receive side-by-side connector terminals of the lead extension plug. Housing contacts within each port provide for electrical coupling with corresponding contacts of the connector terminals of the lead extension plug and are coupled to corresponding contacts of the adapter connector via conductors extending within the elongate body between the housing and the connector.

Implantable neurostimulator adapters

An adapter for coupling a plug of an implantable neurostimulator lead extension to a connector port of a neurostimulator device includes an elongate body, a connector including at least four contacts coupled to a first end of the elongate body, and a housing including at least two ports coupled to a second end of the elongate body. The adapter connector contacts provide for electrical coupling within the device port, and the adapter housing ports are arranged to receive side-by-side connector terminals of the lead extension plug. Housing contacts within each port provide for electrical coupling with corresponding contacts of the connector terminals of the lead extension plug and are coupled to corresponding contacts of the adapter connector via conductors extending within the elongate body between the housing and the connector.

A medical electrical lead having a fixation helix which is surface treated along at least a portion to have a relatively high microscopic area along with a relatively low macroscopic area. In the preferred embodiment, such a surface treated portion is accomplished with a porous platinized construction. The surface treated portion further has a bioabsorbable coating in order to permit the helix to be inserted into the heart tissue without causing damage to the heart tissue through the engagement of the surface treated portion with heart tissue during insertion. In the preferred embodiment the bioabsorbable material is mannitol, although other bioabsorbable materials may also be used, such as a material which is no more than sparingly soluble in water, for example, the steroid beclomethasone dipropionate anhydrous. Through such a construction the helix may be inserted into tissue while the coating of absorbable materials provides a smooth surface between the surface treated portion of the helix and the tissue. Once inserted, the coating is absorbed and the surface treated portion provides electrical contact with the heart tissue.
