Abstract
Aspects of the present disclosure are directed to an electronic switchbox for automatically switching between receive and transmit functionalities. In one embodiment, an electronic switchbox automatically switches between receiving electrocardiograph signals and transmitting cardioversion impulses.
Claims16
An electronic switchbox comprising:
- impulse detection circuitry configured and arranged to detect a pulse emitted from a signal generator;
- and
- a switch matrix including one or more switches, the switch matrix configured and arranged to operate in:
- a first mode whereby the pulse is electrically isolated from an electrocardiograph monitor and a plurality of catheter electrodes, and
- in response to an activation signal from the impulse detection circuitry indicative of the pulse, a second mode whereby the pulse is electrically coupled to at least one of the plurality of catheter electrodes, and a high impedance state protects the electrocardiograph monitor from the pulse;
- wherein the switch matrix is further configured and arranged to facilitate communication of electrocardiograph signals to the electrocardiograph monitor during both the first and second modes using identical catheter electrodes of the plurality of catheter electrodes.
3 more elements
A cardiovascular catheter system comprising:
- a signal generator configured and arranged to generate an electrical pulse for cardioverting or ablating tissue;
- an electrocardiograph monitor configured and arranged to receive and monitor electrocardiograph signals indicative of the electrical activity of a heart;
- a cardiac catheter including a plurality of electrodes along a length of a distal portion, the plurality of electrodes configured and arranged to electrically couple to the tissue and cardiovert or ablate the tissue in response to the electrical pulse;
- an electronic switch box including:
- impulse detection circuitry electrically coupled to the signal generator and configured and arranged to detect the electrical pulse emitted from the signal generator, and
- a switch matrix including one or more switches, an input port, and an output port, the switch matrix electrically coupled to the impulse detection circuitry and the signal generator at the input port, and the plurality of electrodes and the electrocardiograph monitor at the output port, the switch matrix configured and arranged to operate in:
- a first mode whereby the electrical pulse is isolated from the electrocardiograph monitor and the plurality of catheter electrodes, and
- a second mode, in response to an activation signal from the impulse detection circuitry indicative of the electrical pulse, whereby the electrical pulse is electrically coupled to at least one of the plurality of catheter electrodes, and a high impedance state protects the electrocardiograph monitor from the electrical pulse;
- wherein the switch matrix is further configured and arranged to facilitate the communication of electrocardiograph signals to the electrocardiograph monitor during both the first and second modes using identical catheter electrodes of the plurality of catheter electrodes.
6 more elements
A method of operating an electronic switch box comprising:
- in the absence of an electrical pulse, operating in a first mode whereby an input port of the switch box is isolated from an electrocardiograph monitor and a plurality of catheter electrodes electrically coupled to an output port of the switch box, and
- operating in a second mode, in response to the electrical pulse, whereby the input port receiving the electrical pulse is electrically coupled to at least one of the plurality of catheter electrodes, and the electrocardiograph monitor via the output port of the switch box, and the electrocardiograph monitor is protected from the electrical pulse by a high impedance between the output port of the switch box and the electrocardiograph monitor;
- wherein electrocardiograph signals from identical catheter electrodes of the plurality of catheter electrodes are communicatively coupled to the electrocardiograph monitor during both the first and second modes.
