摘要
A deep brain stimulation (DBS) system (10) provides a multiplicity of stimulation channels through which electrical stimuli may be delivered deep within the brain of a patient. The DBS system is powered by a rechargeable battery (27). In one embodiment, the system has four channels driving sixteen electrodes (32). The DBS system is easily programmed for use by a clinician using a clinician programming system (60), and further affords a simple but highly advanced hand held programmer (50) control interface through which the patient may easily change stimulation parameters within acceptable limits. The DBS system (10) includes a small, implantable pulse generator (20) that is small enough to be implanted directly in the cranium of the patient, thereby eliminating the long lead wires and tunneling procedures that have been used in the past. The implantable pulse generator provides electrical stimuli in an open-loop fashion as defined by the stimulation parameters. Further, the DBS system allows up to two electrode arrays (30, 30′) to be attached to the implantable pulse generator (20), thereby eliminating the requirement for implanting two independent implantable pulse generators for bilateral stimulation of deep brain structures.
