Abstract
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.
Claims20
A catheter, 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.
A catheter, comprising:
- a switch including a plurality of input channels and a plurality of output channels;
- a connector including a plurality of contacts, each of the contacts being coupled to a different one of the output channels of the switch;
- a shaft including a plurality of electrodes, each electrode being coupled to a different one of the plurality of input channels of the switch;
- a memory configured to store a first pinout map identifying a first order in which the plurality of electrodes is coupled to the plurality of input channels of the switch;
- and
- a processor coupled to the memory and the switch, the processor being configured to transition the switch from a first state to a second state based on the first pinout map, the second state being one in which the switch is arranged to couple the plurality electrodes to the plurality of contacts in a second order that is compatible with at least one external device.
A method for configuring a catheter, comprising:
- inserting a shaft of the catheter in a deployment location, the shaft including a plurality of electrodes disposed in a linear order on the shaft;
- detecting a plurality of signal changes that occur during the insertion of the catheter in the deployment location, each signal change being a change in a value of a different signal that is received at a respective one of a plurality of channels from one of the electrodes;
- and
- generating a pinout map associating each of the electrodes with a different one of the plurality of channels based on a temporal order in which the signal changes are detected.
