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.

First claim

What is being claimed is:

1. A catheter, comprising: a connector including a plurality of first contacts and one or more second contacts laterally spaced therefrom; 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 one or more second contacts, wherein the memory is configured to: store a pinout map identifying an order in which the plurality of electrodes has been coupled to the plurality of first contacts, wherein the catheter is configured so that any electrode can be coupled to any first contact while maintaining usability; 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; and a handle coupled to the shaft, wherein the memory is disposed inside the handle.

2. The catheter of claim 1 , wherein the plurality of electrodes is coupled to the plurality of first contacts in a random order that is identified by the pinout map to ensure usability of the catheter.

3. The catheter of claim 1 , wherein the plurality of electrodes is coupled to the plurality of first contacts in a non-standard order that is identified by the pinout map to ensure usability of the catheter.

4. The catheter of claim 1 , wherein the memory is further configured to receive the pinout map via the at least one of the one or more second contacts.

5. The catheter of claim 1 , wherein the pinout map includes a plurality of mappings, each mapping identifying a different one of the plurality of electrodes and the first contact the electrode is coupled to.
