Pull-out and embolism performance of patient-specific (PS) versus spherical occluders. a) P-S and spherical occluders filled with Ecoflex 00–30 up to Vinflation ≈ 200%. b) 3D-printed pull-out test jig attached to Zwick tensile tester (left). Force needed to pull occluder out of LAA when inflated by increasing amounts (n = 5, mean ± s.d.). c) Schematic of embolism test setup. P-S or spherical occluder was implanted into the silicone LAA for 48 h to see if occluder would embolize (left). Physiological pressure drops (ΔPleft heart ≈ 15 kPa) and frequencies (f ≈ 1 Hz) were maintained throughout the 48 h.
