Key Terms to Review (18)
Active implantable medical devices: Active implantable medical devices are electronic devices designed to be placed inside the human body, where they can monitor, assist, or treat medical conditions. These devices are powered by an energy source and can perform functions such as delivering electrical stimulation, providing therapeutic drugs, or monitoring physiological parameters. Their complexity requires strict adherence to safety and performance standards to ensure patient safety and efficacy.
Biocompatibility testing: Biocompatibility testing is the evaluation of a material's compatibility with biological systems to ensure it does not cause harmful reactions when introduced into the body. This testing is crucial for medical devices and materials, helping to determine their safety and effectiveness by assessing factors like cytotoxicity, irritation, and systemic toxicity.
CAPA: CAPA stands for Corrective and Preventive Actions, a critical concept in quality management that focuses on identifying, addressing, and preventing non-conformances in processes and products. This systematic approach helps organizations maintain compliance with regulations, especially in the medical technology field, ensuring safety and efficacy in devices and procedures.
Certification: Certification is a formal process that verifies an individual's or organization's competence, credibility, and adherence to specific standards within a professional field. It is often awarded by recognized bodies after an evaluation process and serves as proof that certain qualifications have been met, thereby enhancing trust and safety in various industries, particularly in medical technology where standards ensure the quality and reliability of medical devices.
Compliance: Compliance refers to the adherence to established rules, regulations, and standards set forth by governing bodies or organizations. In the medical technology field, compliance ensures that products and processes meet the necessary quality and safety requirements, which is crucial for patient safety and effective healthcare delivery.
Design control: Design control is a systematic approach to managing the development of medical devices, ensuring that they meet specified requirements and are safe for patient use. This process is crucial in maintaining compliance with regulatory standards, particularly those set by ISO and FDA, and helps to reduce risks during product development.
Document Control: Document control refers to the systematic management of documents to ensure accuracy, integrity, and accessibility throughout their lifecycle.
