Biomaterials Graduate
Project:
Purpose
To apply knowledge of biomaterial properties to a material selection/
biomedical device design problem. This project will be carried out only
by those registered for BIOEN 6900.
Suggested Process
- Select a Class III biomedical device that has or is being developed
for commercial use.
- Identify the various major parts of the device or implant, provide
a drawing or illustration and list the biomaterials used. This may
involve contacting the manufacturer and/or locating the appropriate
information within the patent literature. (Try www.patents.ibm.com
and www.uspto.gov)
- Justify the selection of the materials used with regards to similar
successful applications, physical characteristics, suitability for
processing/ manufacture, cost, and favorable federal regulations.
- Provide an alternative biomaterial solution to at least one of the
key components used in the device and justify your selection based
upon relevant biological principals. List benefits and drawbacks of
the existing components and those of the proposed alternative.
Project requirements
- Project proposal due Feb 3rd, half to one-page maximum. It should
describe the selected device and propose ideas for completing the
project. This will enable the instructor/TA to provide feedback on
the project topic.
- Final report due April 11nd, 15 pages maximum Times New Roman 12
point.
- Oral project presentations of 10 minutes followed by 2 minutes for
questions each during final three lecture periods.
Grading Policy
- The project is worth 20% of your final grade, and includes evaluation
of the preliminary report, final document and the oral project presentation.
- Grading will favor reports that are complete, neat and provide reasonable
rationale for the material selections.
Notes
Classification of medical devices is based on the duration of the device
use, invasiveness and risk to the user.
- Class I devices: crutches, bedpans, tongue depressors, adhesive
bandages etc. These are short-term items, and do not internally contact
the user.
- Class II devices: hearing aids, blood pumps, catheters, contacts,
electrodes etc. These are minorly invasive, but still external and
relatively short-term. But the risk to user is greater.
- Class III devices: cardiac pacemakers, intrauterine devices, intraocular
lenses, heart valves, orthopedic implants, etc. These are long-term,
considerably invasive and can pose immense risk to the user
