US 2014/0190408 A1 · Catheter Tip Coating System

Abstract

A catheter tip coating assembly includes a housing defining a fluid reservoir and having a fluid outlet configured to dispense fluid to an end of a piece of tubing. The catheter tip coating assembly includes a valve assembly carried by the housing and at least partly disposed in fluid communication with the fluid reservoir. The valve assembly is configured to receive the piece of tubing and configured to move between a first position to limit fluid communication between the fluid reservoir and the fluid outlet and a second position to provide fluid communication between the fluid reservoir and the fluid outlet to dispense fluid to the end of the piece of tubing. The assembly provides for careful control over the amount of liquid that is applied and the depth of the wetting.
