A user, such as a clinician or the patient, uses a control device to manipulate at least one neurostimulation parameter. A mapping system uses a calibrated map to map the directional output of the control device to values of at least one stimulation parameter to allow the user to intuitively control the value of the parameter. In some embodiments, where a stimulation device is used to deliver spinal cord stimulation (SCS) therapy for example, the user manipulates a parameter to effect the location and/or strength of paresthesia experienced by the patient. In exemplary embodiments, the parameter values are combinations of electrodes, and the mapping system selects electrode combinations based on the output of the control device such that a direction of movement of paresthesia experienced by the patient corresponds to a direction of manipulation of a directional controller of the control device. The mapping system may calibrate the map based on patient paresthesia information received from a user.

Disclosed are a means and a method for the placement of insulated electrical wires beneath the human scalp in such a way that they will experience no flexing after implantation thus disallowing wire breakage. Specifically, this intracranial system uses wires to connect a control module containing various electronic systems to brain electrodes. These wires are placed in grooves that are made by a surgeon in an outer portion of the patient's cranium by means of a specially shaped burr rotated at high speed by means of a router. At the end of the groove, the surgeon would drill a burr hole in the cranium at the site where a brain electrode is to be placed. A distal portion of each electrical wire would be in the form of a helical coil; one helical coil would be placed in each burr hole. The grooves and burr holes could be filled with an adhesive filler type of material to form a smooth outer surface for the cranium. Also, a special cap could be placed over the burr hole.

In one embodiment, a paddle lead comprises: a plurality of stimulating electrode contacts disposed, the plurality of stimulation electrode contacts being adapted to allow the stimulation paddle to flex transversely about a longitudinal axis; wherein the plurality of stimulation electrode contacts are arranged in at least first, second, and third rows that are disposed perpendicular to a longitudinal axis of the paddle; the first and third rows respectively having multiple electrode contacts electrically coupled to different conductors of the lead to enable the multiple electrode contacts of the first and third rows to function in independent cathode states, anode states, or high-impedance states; the second row being disposed between the first and third rows, the second row having multiple electrode contacts each electrically coupled to a common conductor to cause the multiple electrode contacts of the second row to function in a common cathode state, anode state, or high-impedance state.

A programming device compares filter information to information that describes possible combinations of the electrodes within an electrode set implanted in a patient. The filter information describes at least one characteristic of valid, e. g. , desired, electrode combinations, and in exemplary embodiments, is received from a user, e. g. , a clinician, via a user interface of the programming device. The filter information can describe a number of electrodes in valid combinations, a fixed polarity for an electrode for valid combinations, or relational characteristics of the electrodes of valid combinations. The comparison process may be iterative. The programming device identifies a subset of the possible electrode combinations based on the comparison. By identifying the valid subset of electrode combinations based on the filter information, the programming device may reduce the amount of clinician and patient time required to program an implantable neurostimulator.

Disclosed is a modular system for providing electrical stimulation, in which a first modular electrode section has a contoured back end configured to engage a contoured front end of another electrode section or a tool that may be used to place the first modular electrode section in the patient's body. The contours of the modular electrode section allow the two components to engage with one another so as to prevent their separation in the horizontal plane, and a lead extending from the first modular electrode is configured to engage keels on the top surface of the second electrode portion or tool, with such keels providing a snap-type attachment between the lead and the second electrode portion or tool, such that the two components may be joined together but easily separated from one another through the intentional separation of the lead from the keels on the second electrode portion or tool.

A paddle lead includes a plurality of electrodes configured in at least three rows of three electrodes with the second, intermediate row operable to provide anode guarding. The paddle lead further includes a plurality of grooves disposed on a surface opposite the electrodes to facilitate the insertion of the paddle lead within a patient by inhibiting the veering of the paddle lead to one side or the other of the dorsal column as the paddle lead is advanced along the dorsal column midline during implantation.

Neurological stimulation alleviates chronic pain and other functional neurologic disorders by delivering electrical impulses to the nervous system of a patient. Within this setting, a computer interface optimizes stimulation with commercially available neurostimulators. The computer and interface, in cooperation with a unique graphics input device, deliver arbitrary and unique paradigms of stimulation. The computer interface provides for efficient patient interaction, optimizes stimulation automatically, and reduces the demands imposed on the time of health care professionals.
