Implantable Medical Device

Implantable medical devices, designed to reside within the human body for extended periods, play a crucial role in treating a wide range of medical conditions. From artificial joints and heart pacemakers to sophisticated prosthetics and life-supporting systems, implantable medical devices offer innovative solutions that improve patients' quality of life and extend life expectancy. However, given their intimate and prolonged interaction with human the body, the safety and effectiveness of these devices are of paramount importance. Any malfunction or adverse reaction could have severe consequences for patients, making rigorous testing an absolute necessity before these devices are introduced to the market.

At Meditronics (a brand of STEMart), we recognize the critical importance of ensuring the safety and reliability of implantable medical devices. As a leading provider of testing services in this specialized field, we are committed to offering comprehensive and high-quality solutions to meet the diverse needs of our clients. Our extensive experience and expertise in the industry enable us to conduct thorough evaluations of implantable medical devices, covering all aspects from biological compatibility and mechanical performance to chemical stability and physical characteristics. Our team of highly qualified professionals, with their in-depth knowledge of the latest testing technologies and standards, is dedicated to helping manufacturers and researchers identify potential issues and optimize the performance of their products.

Our Service

• Biocompatibility & Biological Safety: Our comprehensive evaluation adheres to the ISO 10993 series standards, which encompass a wide range of tests including cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogenicity, hemocompatibility, genotoxicity, implantation effects, and chronic toxicity studies.
• Mechanical & Physical Performance: We thoroughly assess the mechanical and physical performance of implantable devices, including evaluating their strength, durability, fatigue resistance, wear characteristics, tensile and compressive properties, flexibility, dimensional stability, and articulation performance under simulated physiological loads and conditions.
• Material Characterization & Degradation: For metallic implants, we perform corrosion resistance tests following standards such as ASTM F2129 and ASTM G71. Chemical characterization is carried out in accordance with ISO 10993-17 and 18, including extractables and leachables profiling using techniques like GC-MS, HPLC, and ICP-MS. We also carry out degradation studies and long-term stability assessments, as well as surface analysis using instruments such as SEM, EDS, AFM, and XPS.
• Sterility Assurance & Package Validation: We perform sterility testing per ISO 11737, bacterial endotoxin testing using the LAL method, and package integrity testing in line with ASTM D4169 and ISO 11607.
• Functional Testing: We verify device-specific performance parameters to ensure that each device functions as intended. This includes testing electrical safety for neurostimulators, flow dynamics for heart valves, deployment mechanics for stents, and other critical performance aspects.
• Accelerated & Real-Time Aging: Predicting the shelf life and long-term performance of implantable devices is essential. We conduct stability studies under simulated physiological environments, including accelerated and real-time aging tests.
