Catheter having two-piece connector for a split handle assembly

A catheter for use with a remote system for diagnosing or treating a patient, comprising:

• a flexible elongated catheter body;
• a distal tip distal of the catheter body and having a plurality of electrodes;
• a control handle proximal of the catheter body;
• electronic circuitry;
• a two-piece connector configured to house the electronic circuitry, the connector having a distal plug assembly and a proximal receptacle assembly,
• the distal plug assembly having:
• a plug insulator having a first plurality of contacts;
• an elongated plug body having a distal portion and a proximal portion, the proximal portion configured to receive the plug insulator;
• a plug insulator lead configured to secure the plug insulator in the proximal portion of the plug body;
• a plug housing configured to receive the distal portion of the plug body;
• and a first cable extending between the control handle and the distal plug assembly, the first cable having a first plurality of electrical leads connected to the first plurality of contacts;
• and
• the proximal receptacle assembly having:
• a receptacle insulator having a second plurality of contacts;
• an elongated receptacle body having a proximal portion and a distal portion, the proximal portion configured to receive the receptacle insulator, the distal portion configured to receive the proximal portion of the plug body;
• a receptacle insulator lead configured to secure the receptacle insulator in the proximal portion of the receptacle body;
• an elongated receptacle housing configured to receive the receptacle body;
• and
• a second cable extending proximally from the receptacle assembly, the second cable having a second plurality of electrical leads connected to the second plurality of contacts;
• wherein each of the first plurality of electrical leads of the distal plug assembly is electrically connected to a respective electrode of the distal tip, each electrical lead passing through the catheter body, through the control handle, and into the distal plug assembly, the two-piece connector configured for operably connecting the catheter to the remote system,
• wherein the electronic circuitry converts signals from the plurality of electrodes into digital signals that can be communicated to the remote system, wherein the plug assembly operably connects the first and second plurality of electrical leads when the proximal portion of plug assembly is received in the distal portion of the receptacle assembly, and
• wherein the proximal portion of the plug body has a key and the distal portion of the receptacle body has a key way, the key and key way configured for one-way engagement.
