Intracardiac imaging system utilizing a multipurpose catheter

摘要

A three dimensional physiological mapping system utilizing an intracardiac echo catheter capable of being located in six degrees of freedom by a visualization, navigation, or mapping system. An echocardiography image of the intracardiac echo catheter may be projected within a geometric model of the visualization, navigation, or mapping system where the location of the projected image is adjusted in response to user input identifying a structure present in the echocardiography image and the geometric model.

主权项

1. An intracardiac echo catheter comprising:
a flexible member having a distal end and a proximal end; a sensor array having an ultrasound transducer and at least three electrodes being attached to the distal end, each of the electrodes configured to generate a position signal in response to an electric field, the electrodes being arranged such that positions indicated by the position signals are not collinear; whereby the position signals allow a visualization, navigation, or mapping system to locate and orient the catheter in space.
