Exemplary patient treatment systems can include a neuromodulator and an implantable signal delivery device electrically coupleable to the neuromodulator. The signal delivery device comprises a lead body including a first region, a second region positionable over the first region, and lead electrodes. The patient treatment system further comprises computer-readable media having instructions that cause the patient treatment system to perform operations comprising: (i) obtaining a physiological parameter of the patient, (ii) generating neuromodulation pulses based on the obtained physiological parameter, and (iii) delivering the neuromodulation pulses to the CSN afferent fibers via one or more of the lead electrodes. The physiological parameter can include at least one of blood pressure, heart rate, bioimpedance, or activity level of the patient.

Abstract: Techniques for configuring electrical stimulation therapy parameters is described. Based on user input, processing circuitry may keep a first therapy parameter substantially constant and increase a value of a second therapy parameter until increasing the second therapy parameter further causes the second therapy parameter to be bigger than threshold value. The processing circuitry may adjust the second therapy parameter value and adjust the first therapy parameter value. Prior to adjustment, the first and second therapy parameters set a first intensity, and after adjustment, the first and second therapy parameters set a second intensity that is greater than or equal to the first intensity. The processing circuitry causes delivery of therapy at the second intensity.

Abstract: A communicator facilitates communications with a remote server via a wireless network supporting a plurality of disparate data transport mechanisms having differing characteristics. A processor coupled to memory is disposed in a communicator housing, which is configured for portability. The memory stores wireless radio firmware and data transfer instructions that are executable by the processor for transferring data to the remote server in accordance with a priority level. The priority level is based in part on criticality of the data and the communicator status. A radio disposed in the housing effects communications via the wireless network in accordance with the firmware. A power source in the housing supplies power for communicator components. The processor executes program instructions for selecting a data transport mechanism among the plurality transport mechanisms based on the priority level, and transmits the data via the wireless network via the radio using the selected transport mechanism.

Abstract: This document discusses a system that includes an intermediary telemetry interface device for communicating between a cardiac rhythm management system or other implantable medical device and a programmer or other remote device. One example provides an inductive near-field communication link between the telemetry interface and the implantable medical device, and a radio-frequency (RF) far-field communication link between the telemetry interface device and the remote device. The telemetry interface device provides data buffering. In another example, the telemetry interface device includes a data processing module for compressing and/or decompressing data, or for extracting information from data. Such information extraction may include obtaining heart rate, interval, and/or depolarization morphology information from an electrogram signal received from the implantable medical device.

Abstract: An implantable cardiac rhythm management device capable of automatically detecting intrinsic and evoked response of a patient's heart and suitable for use during capture verification. The device of the present invention may operate in an automatic capture verification mode, wherein an electrocardiogram signal of a patient's heart is received and used by the device to determine whether a stimulation pulse evokes a response by the patient's heart. The device suspends the automatic capture verification mode and/or adjust the detection threshold dependent upon detected and/or measured noise, a determined amplitude of evoked response, a determined modulation in the evoked response, or detected and/or measured artifact. Further, the sensing circuit of the rhythm management device of the present invention reduces afterpotentials that result due to delivery of the stimulation pulses.
