Documents / Official release
This Defense Intelligence Reference Document, dated 7 January 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office. It is one of a series of advanced technology reports produced in FY 2009 under the Advanced Aerospace Weapon System Applications program. The report reviews biomaterials used in medicine, including silicones, Teflon, biodegradable polymers, hydrogels, titanium, ceramics and tissue constructs, and applications such as stents, joints, contact lenses, drug delivery and dialysis. It concludes that most innovation lies in new ways to apply existing materials.
From the source: Release of 2026-09-18 Incident: 1/7/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD is a broad survey of biomaterials, including metals, polymers, ceramics, glasses, and composites designed to interact with living tissue, and argues that their value depends mainly on biocompatibility, reliability, and careful matching of material properties to specific medical uses. The report reviews major application areas including biosensors, implants, cardiovascular devices, contact lenses, drug delivery systems, tissue constructs, titanium devices, and dialysis membranes, emphasizing that no single biomaterial works best in every setting. Its overall conclusion is that biomaterials are already foundational to a large medical-device industry and save or improve millions of lives, but that progress tends to be slow because safety testing is stringent; as a result, most advances come from improved ways of applying established materials such as silicone, Teflon, biodegradable polymers, ceramics, and titanium in new devices and clinical settings rather than from radically new substances.

OHLY Biomaterials Introduction Biomaterials are metals, ceramics, polymers, glasses, carbons, and composite materials intended to interface with biological systems. They are often used to treat, augment, or replace bodily tissues, organs, or functions. Such materials are used in various forms, including molded or machined parts, coatings, fibers, films, foams, and fabrics. Biomaterials are usually nonliving, but recent definitions also include living skin and tissues produced in culture. A biocompatible material is different from a biological material produced by a biological system, such as bone. Artificial hips, vascular stents, artificial pacemakers, and catheters are all made of biocompatible materials that typically have a synthetic origin. An extraordinarily wide range of medical devices are made from biomaterials. Figure 1 shows some representative examples of medical devices that use biomaterials.

Biomaterial Applications in Medical Devices Encompassing elements of medicine, biology, chemistry, and materials science, biomaterials science has experienced steady and strong growth over its approximately half-century history. Although biomaterials are used primarily for medical applications, they are also used to grow cells in culture, to assay for blood proteins in the clinical UNCLASSIFIED/ /FOR OFFICIAL USE ONLY vi
