Abstract

A power controller device and system allows verification, monitoring, and control of an arteriovenous (AV) fistula creation catheter which comprises a main housing having a power supply, an embedded electronic controller and a user interface display, and which is configured to allow connection to an intravascular catheter. When activated, the device verifies that a valid catheter is connected, downloads stored manufacturing calibration data from the catheter, and provides a user interface to allow initiation of AV fistula creation. Once creation of the AV fistula is initiated, the device provides closed loop control of the catheter heating element and provides a means of monitoring the catheter temperature and tip position to a prescribed parameter to automate the arteriovenous fistula creation procedure.
