Work and damage to the blood vessel. COF measurement is a simple method to test raw materials. 3). A polytetrafluoroethylene (PTFE) tube is commonly used to simulate a blood vessel and is placed in a temperature-controlled water bath. The test sample (guide wire/catheter) is inserted into the PTFE tube by a proximal roller assembly. The pushing force versus advancement distance is measured and plotted to show the trackability of the sample. 2 Contact angle When a drop of liquid is sitting on a flat, horizontal solid surface, the CA is defined as the angle formed by the intersection of the liquid–solid interface and liquid–gas interface.
Particularly, one lot of Biomer® had both antioxidant 4,4′-butylidene-bis-(t-butyl-m-cresol) (BBBC) and UV stabilizer poly(diisopropylaminoethyl methacrylate) (DPA-EMA) while the other lot only had BBBC. FTIR showed almost identical spectra on both polyurethanes. XPS did show different spectra on two lots of polyurethanes but failed to reveal the identity of the chemicals on the surface. 15). 16). Researchers have also used SIMS to investigate the protein adsorption on different materials [57,62–64].
