The basic pin-on-disk setup remains the same, but the dynamic partner is reciprocated rather than rotated, as shown in Fig. 13...

For example, tensile properties measured at room temperature rather than body temperature may be incorrect by 75 to 80 MPa (11 to 12 ksi), and a stent constrained in a catheter exposed to 60 °C (140 °F) will increase pressure against the polymer...
