Device, system, and method for intracardiac diagnosis or therapy with localization

摘要

A medical system for locating a catheter distal tip within a body using a plurality electrical position sensors and a magnetic position sensor in conjunction with an acceleration sensor or rotational encoder. The system locates the catheter by using signals from the acceleration sensor or rotational encoder and magnetic sensors to compensate for positioning errors associated with electric positioning sensors.

主权项

1. A catheter for use in a body, the catheter comprising:
an elongate member comprising a distal portion and a proximal portion; the distal portion comprising a plurality of sensors, the plurality of sensors comprising an acceleration sensor, a plurality of electrical position sensors, and a magnetic position sensor; and a control handle attached to the proximal portion of the elongate member, the control handle comprising a deflection knob configured to deflect the distal portion of the elongate member; wherein the sensors are configured to generate signals such that an electronic control unit may determine a position and an orientation of the distal portion in space utilizing the signals.
