The alloys used in electrophysiology catheters contain the precious metal platinum. This platinum can be separated from the other metals and plastic in the catheter, and be recycled to be used again in other industries. The price that we pay for your catheter is determined by the amount of platinum that we are able to recover from that particular catheter. This amount varies from one manufacturer to the next, and between the different sizes and types of catheters. As we determine ways to improve our recovery efficiency and reduce our costs, your returns will increase. We are proud to give you the best prices we know of, and the best service!
