Abstract
A system to map a cardiac conduction system during open heart surgery includes an electrode support and electrodes held in a fixed arrangement by the electrode support. The system also includes a flexible intermediate component. The electrodes and the electrode support are affixed to a first end of the intermediate component. A rigid handle is attached to a second end of the intermediate component, opposite the first end.

A system to map a cardiac conduction system during open heart surgery, the system comprising:
- an electrode support;
- electrodes held in a fixed arrangement by the electrode support;
- a flexible intermediate component, wherein the electrodes and the electrode support are affixed to a first end of the intermediate component;
- and
- a rigid handle attached to a second end of the intermediate component, opposite the first end.
A handheld cardiac conduction mapping system, comprising:
- a rigid handle;
- a flexible intermediate component coupled to the handle;
- and
- a set of probing portions including at least one probing portion, each probing portion of the set of probing portions comprising:
- an array of electrodes, and
- an electrode support, wherein the array of electrodes is encapsulated in the electrode support.
A method of mapping a cardiac conduction system in a pediatric heart during open heart surgery using a handheld device including a rigid handle, a flexible intermediate component coupled to the handle, and a probing portion including an array of electrodes held in a fixed arrangement by a conformal electrode support coupled to the intermediate component, the method comprising:
- placing the array of electrodes of the probing portion in contact with a first position on the heart by holding and moving the handle, the array of electrodes providing a first set of signals to processing circuitry via wires coupled, respectively, to the array of electrodes, the first set of signals indicating a level of electrical activity at the first position;
- and
- moving the array of electrodes of the probing portion to be in contact with a second position on the heart by moving the handle to raise the probing portion from the first position and holding and moving the rigid handle to place the array of electrodes at the second position based on determining that the cardiac conduction system is not located at the first position, wherein the array of electrodes provides a second set of signals to the processing circuitry via the wires, the second set of signals indicating a level of electrical activity at the second position.
