The term medical device encompasses a vast universe of instruments, machines, and technologies designed to diagnose, monitor, and treat health conditions. From simple thermometers to complex implantable defibrillators, these devices form the backbone of modern healthcare delivery.
Every medical device begins with a clear purpose — to assist clinicians in improving patient outcomes. The development process is rooted in biomedical engineering, blending mechanics, materials science, electronics, and human physiology. Each device must function flawlessly within the delicate environment of the human body.
Medical devices are classified by risk. Class I includes low-risk products such as surgical gloves or stethoscopes, Class II covers moderate-risk technologies like infusion pumps, and Class III represents high-risk, life-sustaining implants like pacemakers.
Innovation in materials science has enabled devices that are smaller, smarter, and more biocompatible. Titanium alloys, silicone polymers, and shape-memory metals are used for implants due to their strength and safety.
Modern devices increasingly rely…
