Catheter-based system having dongle with shape memory
First Claim
1. A system, comprising:
- a catheter comprising an elongated catheter body and a control handle at a proximal end of the catheter body;
a signal processing unit;
at least one monitor;
a patient interface unit configured to connect the signal processing unit to the monitor; and
a dongle configured to couple the control handle of the catheter to the patient interface unit, the dongle comprising;
a dongle body having proximal and distal ends, the dongle body having a first electrical interface unit at its distal end configured for connection to a proximal end of the control handle; and
a dongle support portion having proximal and distal ends and comprising an outer flexible tubular member with shape memory, the distal end of the dongle support portion being connected to the proximal end of the dongle body, the dongle support portion having a second electrical interface unit at its proximal end configured for connection to the patient interface unit.

Abstract
A dongle couples an electrophysiologic catheter and a navigational system, including a patient interface unit (PIU). The dongle permits hardware normally carried on catheter control handle to be relocated onto the dongle to render catheter “greener” and less costly to manufacture use. The dongle having a support portion with flexibility, shape memory and/or varying degrees of stiffness also advantageously allows a user more control over the placement, position and orientation of the dongle. The dongle has a body with a first electrical interface unit, and a support portion with a second electrical interface unit, the support portion having an outer flexible tubular member with shape memory. In one embodiment, the support portion comprises a gooseneck tubing. In another embodiment, the support portion comprises a coiled spring.
