Claim Text:
1. A neuromodulation catheter, comprising: a handle; an elongated shaft attached to the handle, the shaft having a distal portion and a proximal portion, wherein at least the distal portion is configured to be moved within a lumen of a blood vessel of a human patient; an array of contacts at the distal portion of the shaft, wherein the contacts are configured to detect analog neural signals from nerves along the blood vessel while the contacts are within the blood vessel; and a digitizer at the handle of the shaft, wherein the digitizer is configured to receive the analog neural signals from the contacts, digitize the analog neural signals into digital neural signals comprising electroneurogram (ENG) signals, and transmit the digital neural signals to a read/write module external to the patient, wherein the digitizer is configured to filter signals received from the contacts to differentiate the ENG signals from electromyogram (EMG) signals before transmitting the digital neural signals to the read/write module.
