Residues may induceno tissue response, minor tissue irritations, or they may lead tolocal inflammation of tissues surrounding the implant whichmay

28、 lead to failure in short-term or long-term use. Residuesmay also cause harm at locations away from the implant.Residues may originate from manufacturing materials used inthe course of processing, or may be the result of handling andpackaging (1-3).95.2 This practice shall be used to report the resu

Reporting of Residues on Implants6.1 The reporting of cleanliness of implants shall include atable that lists at least sections on (1) the chemical categories,(2) the results of validation studies or of routine analysis, (3)the acceptance criteria if applicable, (4) the det

36、te residues.6.2.2 In this practice, inorganic residues are referred to assubstances of all elements with the exception of carbon-containing substances. Carbonates, graphite or graphite-likestructures (for example, diamond like coatings) are tradition-ally listed as inorganic substances.6.2.3 In this

37、 practice, organic residues are referred to assynthetic and natural carbon-based substances. It includes bothsmall molecules with low molecular mass (for example,paraffin or low viscosity oil) and high molecular mass basedsynthetic polymers. Polysilanes and -oxanes are also consid-ered organic resid

38、ues.6.2.3.1 In this practice, microbiologic residues are to belisted separately and differentiated as bioburden and endotoxin.It should be noted that for medical devices sold sterile,bioburden testing is often part of sterilization validation and ismonitored on a predetermined schedule for the purpo

39、se of doseaudits or process control.6.2.4 In this practice, particulate residues are referred to asmaterial insoluble in aqueous media or organic solvent, whichcan be removed from the surface of an implant by physical-chemical means without interfering with the integrity of theimplant surface. Even

40、though particulates shall be reportedseparately, they belong to one of the chemical classes men-tioned above.6.3 Reported Units:6.3.1 Results of inorganic and organic analysis shall bereported as mass per implant and/or mass per surface area (useSI units).6.3.2 Results of biological analysis shall b
