A catheter for canceling magnetic interference is disclosed. The catheter includes a catheter shaft having a distal end with sensors and a handle with electronics and non-magnetic sensors. Inside the catheter shaft is at least one flexible substrate having conductive traces. Another flexible substrate is wrapped around a component in the catheter shaft. The catheter further includes a plurality of connectors. A first connector connects the sensors to one end of the at least one flexible substrate. A third connector connects the non-magnetic sensors to one end of the other flexible substrate. A second connector and a fourth connector both connect the electronics to another end of the at least one flexible substrate.

Catheter with flexible substrate for minimizing magnetic interference

A catheter is disclosed comprising: a connector including a plurality of first contacts and one or more second contacts; a shaft including a plurality of electrodes, each electrode being coupled to a different one of the plurality of first contacts; a memory coupled to at least one of the second contacts, wherein the memory is configured to: store a pinout map identifying an order in which the plurality of electrodes is coupled to the plurality of first contacts; and provide the pinout map to an external device via one or more of the second contacts after the connector is coupled to the external device.

Random pinout catheter

A method for assembling a catheter is disclosed. The method includes printing conductive traces on at least one flexible substrate and encapsulating the at least one flexible substrate to provide for environmental protection. The at least one encapsulated flexible substrate is inserted into a shaft of a catheter. Then, connectors are attached to each end of the at least one encapsulated flexible substrate. One set of the connectors are further attached to sensors located at a distal end of the catheter and another set of the connectors are further attached to electronics in a handle of the catheter.

Using encapsulated flexible substrate to link sensors and electronics in a catheter assembly

A wiring assembly includes a differential input port, a differential output port, and first and second pairs of electrical leads. The differential input port is configured to receive a differential signal from a sensor at a first end of the wiring assembly. The differential output port is configured to output the differential signal at a second end of the wiring assembly. The first and second pairs of electrical leads convey the differential signal from the first end to the second end, and are connected to one another at the first end and at the second end in a configuration that cancels pickup of an ambient magnetic field by the wiring assembly.

Magnetic pickup cancellation by compensation leads

A system and method for an improved magnetic sensor for use as a three three-axial sensor (TAS) is disclosed. The TAS provides an optimal sensor, concentric and the three coils are identical, with higher sensitivity resulting, a plurality of layers. More specifically, the sensor is made of multiple layers of printed circuit board (PCB). The multiple PCB layers are stacked according to various geometric shapes to create a sensor that enhances positional awareness. Concentric sensors may be arranged in a cube, stacked squares, or stacked squares decreasing in size to form a pyramid structure.
