Dongle with shape memory
First Claim
1. A dongle for coupling an electrophysiologic catheter and a navigational system, including a patient interface unit (PIU), the dongle comprising:
- a body with a first electrical interface unit configured for connection to a proximal end of a control handle at a proximal end of the catheter; and
a support portion with a second electrical interface unit configured for connection to the patient interface unit, the support portion having an outer flexible tubular member with shape memory and first and second ends, the outer flexible tubular member terminating at its first end in the second electrical interface unit and terminating at its second end in the body, the outer flexible tubular member configured to simultaneously bend in multiple directions; and
a printed circuit board housed in the body and hardwired to the first electrical interface unit and the second electrical interface unit, the printed circuit board configured to process electrical signals received from the catheter via the first electrical 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.
