The evaluation was completed.One pack assembly and an i/a handpiece were returned in a plastic zip-lock bag.The original packaging was not received.The part number and lot number cannot be verified or determined.However, the pack is an elite anterior pack.The assembly was dirty with fluid in the lines and a small amount in the collection cassette.The needle on the i/a handpiece was bent.The needle wrench and a purple needle tip was returned in a small plastic specimen cup.One grey colored particle was found taped to the underside of the cap of the specimen cup.The particle was squishy and has a "rubbery" texture.It was approximately 1108 x 1906 microns in size.The particle does not have a metallic appearance.This particle will be sent to the lab for analysis.A lot number was not provided; therefore, the sterilization and lot history records could not be reviewed.The trend analysis, risk analysis and/or directions for use review were considered acceptable, with the product performing within anticipated rates.This investigation is ongoing.

Eds analysis indicated the grey particle consists primarily of carbon and silicon.Lesser concentrations of magnesium, oxygen, chlorine, titanium, sodium, potassium, sulfur, and aluminum where also detected.This is consistent with organic material with mineral fillers.The grey particle was analyzed using a fourier transform infrared (ftr) spectrometer.The ftir analysis of the grey particle produced a spectrum consistent with that of a combination of silicone rubber and polyisobutylene.Lab report indicates material is consistent with silicone rubber and polyisobutylene.A stopper used in non-patient application to plug the collection cassette when it is removed at completion of the procedure is composed of a butyl rubber material, but this is not in the fluid path, and it is unknown how this material could have been involved in any patient contact.This investigation is complete.
