The Prototyping Center is a fee-for-service laboratory providing early stage design and manufacturing of biomedical devices made from advanced materials such as Nitinol, Elgiloy, CoCr, MP35N, and 316LSS.
Nitinol is a relatively new alloy that is being incorporated into commercial and medical applications because of its extraordinary shape memory and superelastic properties. So why is there so much interest in Nitinol?
Nitinol Surgical Devices
- Biocompatibility, Corrosion Resistance
- Super-elasticity (Pseudo-elasticity)
- Shape Memory Effect
- Kink Resistance
- Constant Restoration Stresses
- Physiological Compatibility
Currently, Nitinol is used in the following biomedical applications: cardiovascular stents, kink resistant guidewires, minimally invasive surgical tools, and self-locking orthopedic devices. Key aspects of the advances when using Nitinol are smaller devices for minimally invasive surgical techniques. Other elements of nitinol used for stent applications include RRF (radial resistive force) and COF(constant outward force).
Recent projects include:
- Peripheral vascular stents
- Biodegradable polymer stents
- Heart valve support frames
- Ablation stents
- Aortic stent grafts
- Orthopedic attachments
- Sutureless clip
The center will focus on delivering rapid turn around time for prototype medical devices. The manufacturing capabilities include lasercutting, shape setting, and heat treatment. The state of the art laboratory has an athermal precision laser system, which is able to maintain sub-picosecond pusles that ionize the target material.
