Vascular Catheters have stood the test of time because they are affordable and they work!
These catheters, modified from the original design of Tinsley (1983), are fabricated with medical grade polyethylene (PE) tubing and silicone rubber tubing (RenaSil™). Sealed with a stainless steel plug, when filled with a viscous catheter lock solution they maintain a very high rate of patency* for several weeks.
*Patency, especially for blood sampling, is highly dependent on the location of the intravascular tip.
