Apparatus systems and methods for flushing gas from a catheter of a robotic catheter system
First Claim
1. A system for flushing a lumen of a catheter instrument of a robotic surgical system, the system comprising:
- a robotically controllable catheter instrument having a proximal end, a distal end, and defining a lumen;
a robotically controllable sheath instrument, wherein the catheter instrument is coaxially positioned within the sheath instrument;
a working instrument;
an interface valve having a proximal end, a distal end and defining a lumen, the distal end being adapted for attachment to a proximal end of the catheter instrument, and interface valve lumen being configured to receive the working instrument through the interface valve proximal end for insertion into the catheter instrument lumen;
a fluid supply line coupled to the interface valve, the fluid supply line being in fluid communication with at least a portion of the interface valve lumen;
a first purge line coupled to the interface valve; and
a second purge line coupled to the interface valve, wherein the first or second purge lines comprises a valve coupled thereto for controlling fluid flow through the first or second purge line 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.

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 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.
