SESM6036 Biomedical Implants and Devices
This module provides an introduction to the ways in which engineering methods are used in the design of a wide range of biomedical implants and devices for the treatment of various human diseases. In particular, you will learn about the design and function of auditory implants, cardiovascular implants and devices, prosthetic limbs and how regenerative medicine and tissue engineering are influencing the development of biomedical implants. The relevant background to anatomy, disease, injury and the mechanical properties of biological materials will be covered such that engineering solutions can be presented with respect to the associated clinical needs. In addition to lectures, you will have hands-on lab-based tasks and talks by specialist clinicians.
Aims and Objectives
• To understand the mechanical behaviour of biological cells, tissues and materials, both healthy and diseased; • Relate diseased tissue to the needs of clinical treatment; • Learn how engineering methods are applied to the design of biomedical devices and implants for the treatment of a range of human diseases and disabilities.
Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- Human anatomy, physiology and pathology relevant to the implants studied herein;
- A range of transferrable skills linked to different engineering disciplines but also across the boundaries between engineering and medicine;
- The high standards demanded of devices with respect to production, storage and performance, all related to approval from government agencies
- Issues related to intellectual property and the protection of ideas;
- Creative solutions to challenging biomedical design problems.
- Mechanical properties of biological tissue;
- The clinical needs for implants across a range of human diseases;
- The role of engineering in providing solutions to these particular clinical needs;
- Auditory implants (including cochlear implants);
- Cardiovascular implants and devices (including stents and heart valves);
- Prosthetic limbs
- Stem cells in regenerative medicine;
- How to apply and integrate knowledge, understanding and application of engineering methods from other disciplines in a multi-disciplinary arena (e.g., the use of CAD, FEA and CFD applied to the design of biomedical devices);
