INTRALUMINAL MICRONEUROGRAPHY DENERVATION PROBE WITH RADIO FREQUECY ABLATION
An intraluminal microneurography probe has a probe body configured to be introduced into an artery near an organ of a body without preventing the flow of blood through the artery. An expandable sense electrode and an expandable stimulation electrode are fixed to the probe body at one end of each electrode such that movement of the other end toward the fixed end causes the sense electrode to expand from the probe body toward a wall of the artery. A ground electrode is configured to couple to the body, and a plurality of electrical connections are operable to electrically couple the electrodes to electrical circuitry. The sense electrode is operable to measure sympathetic nerve activity in response to excitation of the stimulation electrode. A radio frequency ablation element is located between the expandable sense electrode and expandable stimulation electrode, and is operable to ablate nerves proximate to the artery.

Pulse Generator System for Promoting Desynchronized Firing of Recruited Neural Populations
An Implantable Pulse Generator (IPG) is disclosed that is capable of sensing a degree to which recruited neurons in a patient's tissue are firing synchronously, and of modifying a stimulation program to promote desynchronicity and to reduce paresthesia. An evoked compound action potential (ECAP) of the recruited neurons is sensed as a measure of synchronicity by at least one non-active electrode. An ECAP algorithm operable in the IPG assesses the shape of the ECAP and determines one or more ECAP shape parameters that indicate whether the recruited neurons are firing synchronously or desynchronously. If the shape parameters indicate significant synchronicity, the ECAP algorithm can adjust the stimulation program to promote desynchronous firing.
BIOIMPEDANCE MEASUREMENT METHOD AND APPARATUS WITH ELECTRICAL STIMULATION PERFORMANCE
A method and apparatus for measuring a bioimpedance and performing an electrical stimulation is provided. The method includes generating a first current corresponding to a first high-frequency, generating a second current corresponding to a second high-frequency, generating a low-frequency current based on a beat phenomenon of the first current and the second current, and calculating an impedance of a target part based on a voltage induced to the target part by a high-frequency current corresponding to at least one of the first current and the second current and the low-frequency current.

Circuitry to Assist with Neural Sensing in an Implantable Stimulator Device in the Presence of Stimulation Artifacts
Sense amplifier circuits particularly useful in sensing neural responses in an Implantable Pulse Generator (IPG) are disclosed. The IPG includes a plurality of electrodes, with one selected as a sensing electrode and another selected as a reference to differentially sense the neural response in a manner that subtracts a common mode voltage (e.g., stimulation artifact) from the measurement. The circuits include a differential amplifier which receives the selected electrodes at its inputs, and comparator circuitries to assess each differential amplifier input to determine whether it is of a magnitude that is consistent with the differential amplifier's input requirements. Based on these determinations, an enable signal is generated which informs whether the output of the differential amplifier validly provides the neural response at any point in time. Further, clamping circuits are connected to the differential amplifier inputs to clamp these inputs in magnitude to prevent the differential amplifier from damage.
METHODS AND SYSTEMS FOR INTERLEAVING WAVEFORMS FOR ELECTRICAL STIMULATION AND MEASUREMENT
A system can utilize interleaving periods or waveforms to stimulate patient tissue and sense signals using the stimulation electrodes. For example, the system can utilize alternating therapeutic periods and sensing periods. As another example, the system can alternate between biphasic waveforms having opposite temporal orders of positive and negative phases. As another example, waveforms that differ in a parameter, such as amplitude or pulse width, can be interleaved to provide different information in the respective sensed signals.
