Abstract:
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.

Abstract:
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.
Abstract:
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.

Abstract:
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.
