Course Contents
In the course Medical Device Design students develop and produce a sound solution to a problem in the medical field in collaboration with their supervisor, clinicians, instrument makers and production companies. The course offers students to work on a design assignment that encompasses the complete design cycle from problem analysis to actual production of the prototype. Each group has a budget of 3000 Euro for production of the prototype. The course is a logical follow-up of the course Biomedical design engineering WB2308.

Students will select a design assignment from a number of options proposed by clinicians (e.g. surgeons, rehabilitation doctors). A conceptual design previously developed in WB2308 could also serve as a base for the development of a physical prototype. The students work in groups of two under close supervision of an instructor on the assignment, to end up with a working prototype. The course is finalized with a public presentation for clinicians and companies and a report.

In weekly meetings of the instructors with all participating groups students are expected to present and discuss the progress in their project in an informal setting.
Study Goals
The student must be able to:
1. Employ a design task with a multidisciplinary team to solve a real technical problem in a medical environment:
translate the clinical problem as presented in the assignment into a practical, technical solution, i.e. do a problem analysis, specify design requirements, come up with a conceptual design, create a cardboard model;
obtain feedback on the clinical feasibility of the concept from the medical assignor to further detail the design.
2. Realize the fabrication of a prototype medical device in collaboration with instrument makers and production companies:
define economical demands;
create detailed drawings, CAD model;
formulate a production plan.
3. Evaluate the performance of the new prototype:
test the technical functionality of the device and/or the clinical applicability of the device in a medical setting;
reflect on previously made design choices based on the performance of the prototype.
4. Present the design to a multidisciplinary audience of technicians, clinicians and (medical) companies.
