The Division of Applied Mechanics (DAM) participates in the Center's mission of protecting and promoting public health by identifying and using applied mechanics to investigate interactions between medical devices and the human body. The division accomplishes this through activities supporting the OSEL mission.
Some examples of research by DAM include determining whether an implanted device will damage blood or create cell damage; conducting tests on the integrity of stents, heart valves, and artificial joints; and devising theoretical, experimental, and computational techniques for dosimetry for high intensity therapeutic ultrasound (HITU). These serve the Center’s mission of advancing regulatory science, facilitating consistent and efficient regulatory pathways, and assuring continued access to safe, effective, and high-quality medical devices.
Specifically, DAM focuses on device issues that involve:
- additive manufacturing (i.e., 3-D printing);
- biologically relevant parameters for devices and materials;
- blood damage;
- computational modeling;
- device and material mechanical integrity;
- device-fluid interactions;
- materials durability;
- transport of heat, drugs, and biological pathogens; and
- ultrasound power measurements, phantoms and dosimetry.
DAM has expertise in the areas of fluid dynamics, solid mechanics and materials, acoustics and ultrasonics, computational modeling, and interventional radiology. Division staff investigate device and material mechanical integrity and durability; blood–device interactions; and develop standard test methods and analytic procedures to evaluate devices, device materials, and products in support of the Center's pre-market and post-market activities.
The DAM staff evaluates interactions of ultrasound with tissue and the implications of these interactions on the safety and effectiveness of devices. In support of their evaluations, they also develop new measurement methods for ultrasound-tissue interactions. Division staff also evaluates the performance of intravascular devices, tissue-device interactions, and emerging technologies in vivo using interventional radiology.
The technical disciplines of the DAM staff include mechanical engineering, materials science, biomedical engineering, general engineering, medical radiology, and physics.
The following represent four division areas in DAM, each containing research programs:
