These are IV catheters that have a Urethane based catheter in place of the typical PTFE (or Teflon®) catheter. The Urethane catheters exhibit qualities that make them superior to the PTFE catheters in this application. They are much more Softer and more Flexible which minimizes the trauma to the animals who in most cases will be debilitated.
