Abstract

Review of the biomechanics, engineering design and forensic failure analysis of implantable medical devices

Highlights

Medical implants are one of the great scientific breakthroughs and represent a growing financial sector
McCloy [1], has reported that the world-wide medical implant market exceeds $200 billion. He estimates that about 20% of adults in the U.S have received an implant of one type or another. These numbers are substantiated by the U.S Department of Commerce [2], which states that the global market for medical devices in 2016 was $339.5 billion and predicted that it would grow to $435.8 billion by 2020
The findings indicated that the most implanted medical device was artificial eye lens (2.582 million lenses)

Summary

Introduction

Medical implants are one of the great scientific breakthroughs and represent a growing financial sector. McCloy [1], has reported that the world-wide medical implant market exceeds $200 billion. He estimates that about 20% of adults in the U.S have received an implant of one type or another. These numbers are substantiated by the U.S Department of Commerce [2], which states that the global market for medical devices in 2016 was $339.5 billion and predicted that it would grow to $435.8 billion by 2020. As with any man-made device, some of these implants will fail. The materials that comprise medical implants fail in many different ways for many different reasons. The primary factors that must be considered include, but are not limited to, manufacturability and manufacturing processing requirements, biocompatibility of the proposed material(s), device geometry, the in vivo and in vitro environmental factors, the normal anticipated and traumatic (if any) loading conditions, and the health and condition of the patient
