Coaxial electrode catheters for extracting electrophysiologic parameters

摘要

An electrophysiology system for mapping tissue includes a catheter having a plurality of electrodes. The system may be a catheter having a dense collection of small electrodes on its tip. The electrodes may be arranged in a pattern that is constant regardless of rotational orientation. The system may be an electrophysiology apparatus having a catheter, the catheter having a body with a proximal end and a distal end. At the distal end of the catheter body is a distal tip comprising a plurality of electrodes and/or coaxtrodes. A signal processor may be operably connected to the plurality of electrodes and/or coaxtrodes and can measure at least one electrophysiological parameter.

主权项

1. An apparatus for use in an electrophysiology procedure, comprising:
a catheter comprising a body having a proximal end and a distal tip region; a plurality of electrodes positioned within the distal tip region; and a signal processor operably connected to the plurality of electrodes to receive a plurality of electrical signals therefrom, wherein the processor analyzes the electrical signals to determine at least one electrophysiological parameter.
