In some cases, a lead icon representing the implanted lead is displayed to show the clinician where the lead is relative to the 3D anatomical regions of the patient.Type: GrantFiled: October 31, 2006Date of Patent: December 17, 2013Assignee: Medtronic, Inc.Inventors: Richard T.

Publication number: 20130331909Abstract: In some examples, a chronic implantable neurostimulator supports trial and chronic modes of operation. In addition, in some examples, the neurostimulator can alternatively include one or more sensors that may or may not function differently in trial and chronic modes. The device may be designed to be used as both a trial neurostimulator and a permanent, or chronic, neurostimulator. A trial neurostimulation period can be used to evaluate the efficacy of the therapy. A percutaneous or implantable trial neurostimulator is used for the trial neurostimulation period. In most cases, the trial period is successful, in which case the trial stimulator is explanted and replaced with a permanent, i.e., “chronic,” implantable stimulator. In accordance with the disclosure, an implantable neurostimulator supports both trial neurostimulation and chronic neurostimulation in the event trial stimulation is successful.Type: ApplicationFiled: August 15, 2013Publication date: December 12, 2013Applicant: Medtronic, Inc.Inventor: Martin T.

Patent number: 8594798Abstract: Apparatuses and methods support multi-modal operation of a medical device system for a nervous system disorder. The medical device system comprises an implanted component and an external component and supports a first feature and a second feature that are associated with the treatment therapy. The medical device system supports both features when the implanted component and the external component are coupled. If the external component is decoupled, the implanted component continues to support the first feature. Moreover, the embodiment may support a plurality of features during a treatment interval. Another aspect of the invention allows for modularly expanding a medical device system in order to add a feature that enhances existing functionality or that provides additional functionality. In an embodiment, a module that is associated with an external component of the medical device system supports the added feature.Type: GrantFiled: October 15, 2003Date of Patent: November 26, 2013Assignee: Medtronic, Inc.Inventors: Ivan Osorio, Mark G.

Patent number: 8579786Abstract: Apparatus and method support a neurological event screening for a medical device. The medical device assists a user in determining a configuration of the medical device for delivering an effective treatment for a nervous system disorder. The medical device detects a neurological event, such as a seizure, and reports a neurological event focus location and a neurological event spread to the user. The user may use the information to provide a configuration of a therapeutic delivery unit and associated therapy parameters. Therapeutic treatment is delivered to the patient, and the medical device is provided an indication of the patient's acceptance to the treatment. The user may modify the configuration and therapy parameters in order to achieve efficacy and acceptance. Depending upon the patient's acceptance, therapy is applied in either an open loop mode or a closed loop mode. The medical device determines whether the treatment is successful in accordance with a criterion.Type: GrantFiled: October 15, 2003Date of Patent: November 12, 2013Assignee: Medtronic, Inc.Inventors: Ivan Osorio, Mark G.
