Figure Lengend Snippet: Evolution of Pulsta valve. From animal study to human clinical trial, Pulsta valve design changed several times to increase radial force and not to be folded in longitudinal axis. Inside of stent wall is covered by treated porcine pericardium with 25 mm height. The outer diameter ranges from 18 to 32 mm. Both ends of the valve are flared 4 mm wider than the outer diameter. The maximum total length of the Pulsta valve is 28, 31, 34 and 38 mm according to the outer diameter.

Article Snippet: Therefore, we need a larger Pulsta valve greater than 32 mm to expand the indication of Pulsta valve and TaeWoong medical company is trying to make bigger Pulsta valve for future candidate patients with large main PA which cannot accommodate 32 mm Pulsta valve.

Figure Lengend Snippet: Hook attachment mechanism. If the hook and proximal strut of Pulsta valve are in the same plane from the fluoroscopy, one of the hooks still might be in caught with the valve proximal strut (A and C, black arrows). Depending on the wire position, hook can be caught in the right anterior side proximal strut (B, black arrow) or the left anterior side proximal strut (D, black arrow).

Figure Lengend Snippet: The Module-Fluidic generates the desired concentration profile that enables downstream microfluidic devices’ function.

Article Snippet: All the valves are controlled by a microfluidic valve control matrix (MUX QUAKE VALVE, Elveflow) with sixteen independent pressure outlets that can provide a constant pressure input when they are switched on.

Figure Lengend Snippet: Structures of the Spatio-Temporal Concentration Controller. ( A ) 3D structure of Signal generator (Oscillator) and Module Connector (Integrator), the Oscillator consists of three layers, the PDMS structure layer has flow channels patterned. The channel is molded using positive photo resist which produces a semi-cylindrical cross-section for complete sealing of the micro valve. The second layer is a thin PDMS membrane with controlling valves when the air pressure (∼20 psi) is applied, valve will seal the channel. The third layer is glass slide to support the entire structure. All layers are bounded to each other using plasma bonding. The Integrator is a single microfluidic channel with depth 25 µm. The PDMS layer is also bounded to a glass slide; ( B ) Drawings of the oscillator and integrator ( C ) Concentration signal generation achieved by combination of valve status; ( D ) Function generated by the oscillator.
