Patent ID: 11382566

Abstract:
Cardiac interventional devices are fitted with sensors coupled to an electrophysiology (EP) mapping system. The sensors can be in the form of electrodes and/or magnetic field sensors which are placed strategically upon the interventional devices. The interventional devices can thus be visualized on the EP mapping display when the interventional devices are being routed through various pathways adjacent to the heart of a patient. The interventional devices can include sheaths, and especially two part sheaths with a base separate from a tube, which base can be separated from the tube at an interface. Other interventional devices include an exoskeleton attachable to a lead, needles, guide wires, dilators, J wires and luminal catheters. The sensors are located along the interventional devices, typically including a sensor at a distal tip, as well as along a length of the interventional device, proximal of the distal tip, and with known spacing to further allow the interventional device to be fully and accurately caused to appear on the EP mapping display.
