  • Publication number: 20150302178
    Abstract: A system and associated method receives, by a database coupled to a communication network, patient medical data from multiple data sources including data retrieved from implantable medical devices implanted in patients. A processor accesses the database to generate a dataset from the medical data having at least one data characteristic matching a corresponding data characteristic of a patient group of at least one patient. At least one subset of the dataset is identified that had a therapy intervention subsequent to a time point that the subset had the matching data characteristic(s). An outcome of the subset is determined and a predictive outcome for the patient group is produced based on the outcome of at least one subset.

  • Patent number: 8961505
    Abstract: A device includes a plurality of electrodes and a detection module. The plurality of electrodes are configured to acquire an electrical signal in a patient. The detection module is configured to determine whether the acquired electrical signal includes signal content in each of N different frequency bands and detect operation of an electrosurgical device on the patient based on how many of the N different frequency bands include signal content. N is an integer that is greater than 1.

  • Publication number: 20120109238
    Abstract: A system includes a data retrieval module and a determination module. The data retrieval module receives a command from a user, the command indicating a first implantable medical device (IMD) and a second IMD. The data retrieval module also retrieves a first set of data from the first IMD in response to the command and retrieves a second set of data from a datastore. The second set of data includes data retrieved from the first IMD and stored in the datastore prior to receiving the command. The determination module determines a third set of data based on the first and second sets of data and transfers the third set of data to the second IMD.

  • Patent number: 7366570
    Abstract: A method and system facilitates the access by a patient of implanted medical device related data for patient participation in their own clinical care and therapy. In an example embodiment, the method includes establishing a communications link between an implanted medical device and a data processor via an implanted medical device interface. Access to a secured database is obtained via the implanted device data processor using a set of patient identification data. A query is then submitted via the data processor to the secured database in response to input patient diagnostic data. Data received from the secured database is then displayed for use in a patient evaluation.

  • Patent number: 7272433
    Abstract: An external physiologic or implanted device monitor/controller (“monitor”) designed to be attached to the body, as for example, to the skin of the patient. The monitor is designed to detect the therapeutic outputs actually produced by the implanted medical device. Having knowledge of the operation of the implanted medical device, the monitor may then deduce, or decode, the physiologic conditions and/or devices conditions sensed by the implanted medical device. The monitor is then able to perform an action appropriate to the sensed condition and the specific implementation.

  • Patent number: 6529771
    Abstract: An implantable medical device determines activity levels and Heart Rate and from a combination of these produces a value for a heart rate activity coefficient (HRAC). This value has significant diagnostic and patient tracking value. Methods and apparatus for determining this HRAC value are described. This enables physician review of patient cardiac status. Additional physiologic data can be recorded along with the HRAC data if desired, and this too, as well as the HRAC data alone, may be reported out from the implanted device to a medical communications system for alarm purposes, titrating drugs/therapies or other monitoring tasks. Further, substitutes for heart rate measurements and activity measurements are described which can be used to augment or substitute for heart rate measurements and activity measurements.

  • Patent number: 5987352
    Abstract: A minimally invasive implant, means for insertion, and description of how to most efficiently use it are described n several embodiments. This implant preferably has a segmented looping memory for storing triggered physiologic events. Preferred events for setting autotriggers to record physiologic signals occurring during events include arrhythmias and syncopal events. Preferably the device can function without a microprocessor. An outside device or other patient activated manual trigger is included. Auto triggers and manually set triggers may be of different sizes. The preferred physiologic events are ECG signals. Electrode spacing can be critical. Additional sensors may be provided to the device. Preferred communications with the device is through telemetry such as is used for pacemakers and other implanted devices.

  • Patent number: 5441525
    Abstract: A rate-responsive cardiac pacemaker implements a novel scheme which detects incipient vasovagal syncope (or other episodes caused by a vasodepressive or cardioinhibitory disorder) when a) the heart rate drops below a programmable minimum size, and b) the rate after said drop is below a programmable maximum drop ending rate. The pacemaker implements a stability and intervention procedure upon the detection of an episode, in which it ignores transient drops in rate, and paces at a predetermined high rate if the drops are stable. The pacemaker then gradually reduces the pacing rate over a predetermined time to the pre-episodic level. A sleep disable feature disables the vasovagal syncope detection and therapy features during the patient's sleeping hours to reduce or eliminate false positive responses.
