A prosthetic valve for placement within a body passage includes at least two valve leaflets made from a first layer of either peritoneal fascia tissue or pleural tissue. The securing block defines a step hole and a cutout. The exhaust chamber has an air inlet connected to the process area receiving air exhaust from the process area, and an air outlet venting the air exhaust. The patient support includes a body support rotatably coupled with right and left leg supports disengageable at the outboard ends, that can be tilted, rotated and locked in place. The tubular body is compressed between the workpiece and bushing as the bushing is displaced radially causing corresponding radial displacement of the tubular body.
