APPARATUS SYSTEMS AND METHODS FOR FLUSHING GAS FROM A CATHETER OF A ROBOTIC CATHETER SYSTEM
First Claim
1. An apparatus for sealingly engaging a working instrument configure for insertion into a robotically controllable guide catheter, the apparatus comprising:
- a chamber body having a proximal end configured for receiving the working instrument and a distal end configured for interfacing with a proximal end of the guide catheter, wherein the working instrument includes an elongate body that can be advanced through a lumen defined by the chamber body and into a lumen defined by the guide catheter;
a fastener coupled to the proximal end of the chamber body and configured to removably secure the working instrument within the chamber body lumen; and
a plurality of compliant spacer elements positioned in the chamber body to provide a fluid tight seal along a portion of the elongate body of the working instrument located within the chamber body.

Abstract
Apparatus, systems and methods for flushing a lumen of a catheter instrument to reduce or eliminate bubbles within the lumen. An interface valve is adapted for attachment to a proximal end of the catheter instrument and can receive a working instrument for insertion into the he catheter instrument lumen. A fluid supply line and purge lines are coupled to the interface valve and in fluid communication with at least a portion of the interface valve lumen. Flow of fluid (e.g. saline and a gas such as bubbles) through purge lines is controllable using clamps such that fluid flowing into the interface valve lumen can be manipulated to flow in different directions through different portions of the interface valve lumen for evacuation through different purge lines, thus allowing for purging of forward and backward flows to remove gas or bubbles from the catheter instrument lumen.
