20100010383 | REORIENTATION OF PATIENT POSTURE STATES FOR POSTURE-RESPONSIVE THERAPY - In general, the disclosure relates to medical devices and systems configured to deliver posture-responsive therapy to a patient. For example, a medical system may detect a posture state of a patient and deliver therapy based at least in part on the detected patient posture state. In some examples, the system comprises a posture state sensor configured to generate first posture sensor data when a patient is in a first posture state. The system may further comprise a processor configured to define posture state reference data corresponding to the first posture state based at least in part on the first posture sensor data, and redefine the posture state reference data based on second posture data generated by the posture state sensor when the patient is in the first posture state. | 01-14-2010 |
20100010387 | OBTAINING BASELINE PATIENT INFORMATION - The disclosure relates to a method and system for obtaining baseline patient information. In some examples, a method may include acquiring first patient data, wherein the first patient data comprises at least one of first posture state data indicative of a plurality of posture states of a patient during a first time period or first therapy adjustment data indicative of a plurality of patient therapy adjustments made during the first time period; generating baseline patient information based at least in part on the first patient data; and comparing the baseline patient information to patient information generated based on second patient data. Therapy is not delivered to the patient according to a detected posture state of the patient during the first time period, and therapy is delivered to the patient according to the detected posture state of the patient during the second time period. | 01-14-2010 |
20100010392 | MODIFICATION PROFILES FOR POSTURE-RESPONSIVE THERAPY - In general, the disclosure describes techniques for modifying therapy provided to a patient by a medical device. The techniques may be applicable to electrical stimulation therapy or other therapies. Modification of therapy may include adjustment of one or more therapy parameter values that define one or more characteristics of stimulation therapy delivered to a patient. The therapy modification may be based on activity of a patient that is detected by an IMD, such as a change in a detected posture state occupied by the patient. Different therapy modifications may be applied for different changes in detected posture state. An IMD may modify therapy based on a transition from one posture state to another posture state, and apply different modifications for different transitions. In some aspects, the modification may include a profile, such as a ramp up or ramp down in a parameter value over a period of time. The profile may be different for different posture transitions. A ramp slope may be steeper for one transition than for another transition. When a patient transitions from an upright to a lying posture state, for example, the profile may be especially abrupt. In some examples, a modification profile may define a dwell time. | 01-14-2010 |

20110082522 | CLOSED-LOOP THERAPY ADJUSTMENT - Techniques for detecting a value of a sensed patient parameter, and automatically delivering therapy to a patient according to therapy information previously associated with the detected value, are described.

20140163644 | MINIMALLY INVASIVE IMPLANTABLE NEUROSTIMULATION SYSTEM - An external medical device generates a drive signal inductively coupled to an implantable coil from an external coil. A regulator module coupled to the implantable coil generates an output signal in response to the inductively coupled signal and a feedback signal correlated to an amplitude of the inductively coupled signal. A signal generator receives the output signal for generating a therapeutic electrical stimulation signal. The control module adjusts the drive signal in response to the feedback signal to control the electrical stimulation signal. | 06-12-2014 |
20140180870 | METHODS, SYSTEMS, AND DEVICES FOR AUTHORIZING PERFORMANCE OF A MEDICAL TASK BY AN IMPLANTABLE MEDICAL DEVICE - An authorization is required for performance of medical tasks by an implantable medical device (IMD). The authorization may be based on a process implemented by the IMD to check for the authorization. As an alternative, the authorization may be based on a process implemented by an external device, such as to check whether there is authorization to provide a power transmission to the implantable medical device that is necessary for the IMD to perform the medical task. This authorization allows a fee to be charged to performance of the medical task, which in turn allows the initial cost of the IMD to be substantially reduced. This in turn increases the population of patients that are able to afford the IMD to improve their quality of life, which increases the number of IMDs that can ultimately be sold. | 06-26-2014 |
