Extendable flushing system
First Claim
1. An extendable flushing system for use with a medical device having an elongate shaft with a lumen extending therethrough, the extendable flushing system comprising:
- flexible tubing having an extended configuration and a compressed configuration, a first tubing end and a second tubing end;
a flush port having a first lumen operably connected to the first tubing end and an opening configured to receive fluid therethrough;
a shuttle assembly operably connected to the second tubing end forming a fluid flow path with the flush port and the shuttle assembly, the shuttle assembly configured to be fluidly connected to an elongate shaft lumen and the shuttle assembly movably positionable relative to the flush port and configured to move the flexible tubing between the compressed configuration and the extended configuration;
an outer sheath operably connected to the flush port and the shuttle assembly and movably positionable with the shuttle assembly; and
an inner catheter coaxially extendable through a lumen of the outer sheath, the shuttle assembly and the outer sheath longitudinally movable relative to the inner catheter.

Abstract
An extendable flushing system, a delivery system including an extendable flushing system and a method of flushing a delivery system are provided. The extendable flushing system includes flexible tubing having an extended configuration and a compressed configuration, a first tubing end and a second tubing end. The extendable flushing system also includes a flush port and a shuttle assembly. The flush port includes a first lumen operably connected to the first tubing end and an opening configured to receive fluid therethrough. The shuttle assembly is operably connected to the second tubing end forming a fluid flow path with the flush port and the shuttle assembly. The shuttle assembly is configured to be fluidly connected to a lumen of an elongate device. The shuttle assembly is movably positionable relative to the flush port and configured to move the flexible tubing between the compressed configuration and the extended configuration.

17. A method of flushing a delivery system having an outer sheath movable relative to an inner catheter, the method comprising:
-
providing an extendable flushing system comprising; flexible tubing having an extended configuration and a compressed configuration, a first tubing end and a second tubing end; a flush port having a first lumen operably connected to the first tubing end and an opening configured to receive fluid therethrough; a shuttle assembly operably connected to the second tubing end forming a fluid flow path with the flush port and the shuttle assembly, the shuttle assembly movably positionable relative to the flush port and configured to move the flexible tubing between the compressed configuration and the extended configuration; an outer sheath operably connected to the flush port and the shuttle assembly and movably positionable with the shuttle assembly; and an inner catheter coaxially extendable through a lumen of the outer sheath, the shuttle assembly and the outer sheath longitudinally movable relative to the inner catheter; connecting a fluid source to the opening in the flush port; and injecting fluid into the port, through the tubing to the shuttle assembly and into a lumen of the outer sheath.
