Thank you for the questions! I can answer both your questions at once. We are limited to polymer materials. HOWEVER, certain plastics have reactions that MAY have toxin issues. PVC catheters were phased out because new materials were developed that have better bio-compatibility. We can texture the PVC catheters and achieve similar results as what we've already seen. *Polyethelene is a common material for catheters, and while we can texture it the material forces us to add heat to the equation. Removing heat is a critical step that we removed cause it's time intensive. WORST case scenario, our method with heat is still cheaper and faster then current nanotexturing methods.
