I seriously doubt any critical medical part can be made for $1. If that part fails, there are likely serious consequences for the patient. Sure the plastic is cheap, but the manufacturer will likely do several expensive steps to reduce the failure rate: Each part is traceable from all raw materials to finished product Each part is manually tested/calibrated Each part may be tested with non-destructive testing (x-ray, ultrasound, dye crack inspection etc) For every lot of parts, several parts will be tested destructively Each part comes with liability, so the manufacturer will likely purchase liability insurance Also, the regulatory costs are paid years in advance of a single unit being sold. Once the device is approved (that is, if it's approved at all), the units are sold slowly over years. So the regulatory costs must be financed.
