Tygozahn The concept is straightforward — if it can be shown that an impurity is below the TTC, then it is assumed that the level of contamination is of no significant risk and no further evaluation is required with regard to that impurity. The concept may also be applied more generally to unidentified contaminants.

Posted In: Blog , Blog Morulaa Biocompatibility is a measurement of how compatible a device is with a biological system not generating any local or systemic responses from a living system or tissue. In the simplest sense, a biocompatible material or device does not harm the patient.
From a regulatory view, it is a series of tests that are used to determine the toxicity resulting from contact of the parts of medical devices or combination products with the body. A medical device may consist of materials that are biocompatible, although the device itself requires biocompatibility testing and all testing is performed on the final product. ISO Standard for Biocompatibility Testing: Common biocompatibility testing, such as those described by ISO , is conducted prior to clinical evaluation of the device or clearance to market the product.
This testing involves analysis of the device if non-toxic and non-allergic as per ISO standard. The purpose of this testing is to determine the fitness of a device for human use, and to check whether the device can have any harmful physiological effects. Implementation of ISO varies, based on the risk associated with the use of the product. Many of the biological screens that comprise the remaining parts of ISO are designed to estimate specific aspects of biocompatibility, and therefore are not required for all medical devices.
ISO: ISO was established to determine a uniform worldwide standards and it is a non-governmental network of national standards institutes and acting as a bridge between the private and public sectors.
Depending on the nature type and duration of body contact of a medical device, tests for some or all of the following effects may be recommended: ISO Risk management process ISO Animal welfare requirements ISO Tests for genotoxicity, carcinogenicity and reproductive toxicity Genotoxicity- Gene or point mutations ,small deletions, mitotic recombination or microscopically visible chromosome changes Carcinogenicity- Ability of a carcinogen to produce invasive cancer cells from normal cells.

Part 18 was substantially revised and is now proposed to be converted from a Technical Specification to a full standard. It does not apply to tests performed on invertebrate animals and other lower forms; nor other than with respect to provisions relating to species, source, health status, and care and accommodation does it apply to testing performed on isolated tissues and organs taken from vertebrate animals that have been euthanised.
