摘要： A system is provided for identifying and reducing noise in a therapeutic procedure. For example, the system may be configured to measure one or more signals with cardiac activity. The system may be configured to then identify one or more sources of noise that are distorting the one or more signals with cardiac activity and may reduce the one or more sources of noise from the one or more signals with cardiac activity. Subsequently, the system may be configured to determine one or more aggregate cardiac-derived metrics and/or save processed cardiac data based on the one or more signals with cardiac activity with the one or more sources of noise reduced. Additionally, the system may be configured to determine one or more parameters for applying an electrical signal to an anatomical element of a patient based on the one or more aggregate cardiac-derived metrics and/or saved processed cardiac data.

The medical device may have a plurality of electrodes, and may be configured to measure impedance for each of the plurality of electrodes and generate impedance data. The eternal device(s) may include a display and a processor. The medical device may be configured to communicate the generated impedance data to the at least one eternal device. The processor may be configured to provide on the display a plurality of electrode icons corresponding to the plurality of electrodes, to determine, based on the impedance data, one or more impedance state electrodes from the plurality of electrodes that have an impedance state, and to provide on the display an impedance status representation for one or more of the plurality of electrode icons corresponding to the one or more impedance state electrodes.

摘要： Methods and systems for testing and treating spinal cord stimulation (SCS) patients are disclosed. Patients are eventually treated with sub-perception (paresthesia free) therapy. However, supra-perception stimulation is used during “sweet spot searching” during which active electrodes are selected for the patient. This allows sweet spot searching to occur much more quickly and without the need to wash in the various electrode combinations that are tried. After selecting electrodes using supra-perception therapy, therapy is titrated to sub-perception levels using the selected electrodes. Such sub-perception therapy has been investigated using pulses at or below 10 kHz, and it has been determined that a statistically significant correlation exists between pulse width (PW) and frequency (F) in this frequency range at which SCS patients experience significant reduction in symptoms such as back pain. Beneficially, sub-perception stimulation at such low frequencies significantly lowers power consumption in the patient's neurostimulator.

摘要： A subcutaneously implantable device includes a housing and an anchoring mechanism attached to the housing that is configured to anchor the device to a muscle, a bone, and/or a first tissue. The device further includes a first prong with a proximal end attached to the housing and a distal end extending away from the housing that is configured to be positioned adjacent to a first blood vessel, and a first electrode on the distal end of the first prong that is configured to be positioned adjacent to the first blood vessel. Circuitry in the housing is in electrical communication with the first electrode that is configured to deliver electrical stimulation using the electrode to create an electric field around the blood vessel.

摘要： A system and method of quantifying, maintaining and managing the functional status and/or therapy settings of an IMD based on code path metrics is disclosed. The codebase of device firmware modules may be instrumented to obtain tracing data and timing metrics data corresponding to different code paths that may be taken when a device subsystem or associated functionality is accessed or activated. Code path metrics of actual code paths may be analyzed to detect a deviation from baseline code path metrics and generate a corresponding graduated response.

摘要： An opto-electronic probe system is disclosed. The probe system has a probe element including at least one microelectrode, with the probe element being implantable in tissue of an anatomy to receive electrical signals generated within the anatomy. A subsystem is included for at least one of generating excitation signals to be used in stimulating the anatomy, or for receiving electrical signals received from the anatomy. An interface portion is included which is in communication with the subsystem for communicating at least one of electrical signals or optical signals indicative of the electrical signals received by the microelectrode.
