Paragraph starter
The historical development of metals in biomedical applications, as evidenced by the evolution from early implants to the introduction of corrosion-resistant alloys like 18-8 stainless steel, underscores the critical importance of material selection. Early failures due to corrosion and insufficient strength necessitated advancements, demonstrating that the longevity and success of medical devices are intrinsically linked to the material's ability to withstand biological environments and mechanical stresses over time. This principle is vital when designing any product intended for prolonged human interaction or internal use.
