Figure 2: Representative BTC2000™ data showing pressure- time curves on the first row, deformation- time curves on the second row, and stress-strain curves on the third row. The modulus was calculated between the values obtained at 150 mmHg and 75 mmHg (arrows in stress-strain curve). The energy absorption was obtained from the area under the stress-strain curve. The negative pressurization and relaxation collection times are 6 and 2 seconds, respectively.
