Draft FDA Guideline for Quantifiable Validated Cleaning
LIC can assist Instrument Manufacturers in qualifying their instruments as reusable* LIC can provide FDA approved protocols and test methods for validated cleaning.
* LIC will label it's device for cleaning of their instruments.
* LIC will provide the OEM with cleaning reprocessing instructions for their labeling.
* OEM can test the cleaning of the instrument early in the development process and make
the necessary design changes before production and FDA regulatory testing.
* LIC's device provides the manufacturer with the means to clean and validate in the final
manufacturing step before packaging and sterilizing.
Dramatic change in FDA policy regarding the Requirement to qualify as Reusable: developworst case soiling and cleaning endpoints using AAMI TIR 30 as the FDA suggested

The LIC Parametric Release ™ Instrument Processor System is unique in that the technology eliminates the need for connectors and is designed to process a variety of medical instruments including but not limited to endoscopes in a single chamber. It is the first and only Parametric Release liquid chemical Instrument Processor System that delivers the three critical steps required to process a reusable medical instrument, i.e. integrates cleaning to less than 2 micrograms of protein per square centimeter, sanitizes to greater than 10-6 with no surviving microorganisms and rinses the germicide residue with sanitized rinse water without compromising the sanitizing step.

1) The instrument processor does not useconnectors to attach to the instrument being
processed in order to direct the flow of
chemical detergent and germicide, so that all
external and internal surfaces are exposed to
the detergent and germicide.
2) No brushes are used that may scratch andscore the inner or outer surfaces of the device

The chamber, baffle and tray are heavily contaminated with Hucker's soil. Not only were these mock lumens soiled internally and externally; all the surfaces of the chamber, the baffle and the tray top and bottom were also soiled.
Our processor safely and effectively cleaned the Hucker's soil from all the contaminated surfaces.
Washers merely agitate the fluid whereas our processor producesmechanical shear that strips the toughest soiling from surfaces.
This mechanical shear is developed at 12.5 psi.
OBJECTIVE: Evaluation of a proposed cleaning process for a fully intact Trocar utilizing the LIC Instrument Processor to determine if a Trocar can be cleaned without disassembling it.
BACKGROUND: A recent design change of the J&J Trocar, the Endopath Xcel, incorporatesan internal foam pad that has been a
challenge to clean both because of it's
surface texture and its isolated location
within the Trocar.
A further challenge that has been imposed is the excessive amountof organic soil (composed of horse serum, defibrinated sheep's
blood, and subjected to salt pork) which has been placed inside the
Trocar. The Trocar was subsequently baked in an oven at 60 0
Centigrade for 72 hours. This excessive amount of dried organic
soil interior to the Trocar has been observed and photographed by
disassembling another Trocar inoculated in the same group. After baking,
the Trocar sat for approximately 10 weeks prior to this feasibilty cleaning
Feasibility Evaluation report SummaryTrocar cleaning process
The testing demonstrated that the soiled fully intactEndopath Xcel trocar is an acceptable candidate
for cleaning using the LIC Instrument Processor
System. The Endopath Xcel Trocar was cleaned
to a level where no visible trace of any soiling
was detectable after disassembly of the separate parts of the trocar. Succesfuly proving that using the LIC Instrument Processor negates the need to disassemble and reassemble the Endopath Xcel Trocar in order to clean it for sterilization and eventual reuse. Thus proving that disassemblingand cleaning of each individual part of thetrocar is not necessary when it is cleaned in the LIC Processor.
The LIC Instrument Processor System cleaning
cycle is capable of removing all visible evidence
of the test soil and therefore based on prior
experience with similar devices should exhibit
