| 20080319511 | AUTO ADJUSTING SYSTEM FOR BRAIN TISSUE STIMULATOR - An implantable neurostimulator for treating disorders such as epilepsy, pain, movement disorders and depression includes a detection subsystem capable of detecting a physiological condition and a therapy subsystem capable of providing a course of therapy in response to the condition. The therapy subsystem includes an auto-adjust module for automatically adjusting one or more parameters of the therapy so that the therapy subsystem can provide an adjusted parameter to the patient and solicit the patient's feedback concerning the adjustment without requiring the presence of, or immediate involvement with, a clinician or physician. The patient feedback can be analyzed by computer, clinician or a combination of both to determine an optimal range of parameters for subsequent courses of therapy. In this manner, information useful in tuning the neurostimulator therapy parameters to optimize them for individual patient can be acquired automatically outside of the traditional clinical setting, saving time and minimizing patient fatigue that otherwise would be experience in marathon, in-clinic tuning sessions. The auto-adjust module also can be configured to prompt the patient to provide feedback even when parameters are not being adjusted, so as to acquire information for a baseline or about any placebo effect when the patient is otherwise expecting changes to the therapy to be made. | 12-25-2008 |

The external device is programmed to interact with other similarly-enabled devices. The system facilitates improved patient care by eliminating unnecessary geographic limitations on implantable medical device interrogation and programming, and by allowing patients, physicians, and other users to access medical records, history, and information and to receive status and care-related alerts and messages anywhere there is access to a communications network. | 12-31-2009 |
| 20100073677 | METHOD AND SYSTEM OF DEVICE IDENTIFICATION - A medical device susceptible to identification using interference patterns for performing device identification is disclosed. A source signal may be directed from an energy source towards the surface of a device for reflection therefrom. An interference pattern may be detected from the surface of the device, such as by a sensor. A determination as to whether a match exists between the representation of the interference pattern and a stored representation of an interference pattern may be performed. If a match exists, the device may be identified based on the stored representation of the interference pattern. Otherwise, a representation of the interference pattern may be stored and a unique identifier may be assigned to the stored representation of the interference pattern. | 03-25-2010 |
