There are a wide range of plastics that can be used in medical devices.  Plastic selection depends on application as well as cost and manufacturability. 

Just some of the many plastics typically used in medical devices include polycarbonate, PMMA (acrylic), (PA) nylon, PVC (polyvinyl chloride), polypropylene, polyethylene, PTFE (Teflon), and ABS.  Here we will give a brief overview and talk about some applications for each.

For more information on plastics in medical devices, a well-detailed plastic selection guide comparing cost, mechanical properties, electrical insulating properties, temperature resistance, and chemical resistance can be found here: https://www.curbellplastics.com/Research-Solutions/Technical-Resources/Technical-Resources/Plastic-Material-Selection-Guide
 
Additionally, a good summary and comparison of material properties can be found here: https://saliterman.umn.edu/sites/saliterman.dl.umn.edu/files/general/medical_device_polymers.pdf
