Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The method comprises requesting the state of a replica system. Each sidewall extends from a front mounting structure to a rear mounting structure and carries a track that typically extends the almost entire length of the sidewall for supporting the carriage of the sootblower within the canopy. The front panel is secured to the sides, using modified pop rivets, enabling the front panel and sides to be adjustably secured to one another to adjust the overall girth of the device and to differentially adjust the girth along upper and lower portions of the device to accommodate individuals of different waist and hip sizes. The stick driver circuit on the data line side, which is composed of a shift register circuit, a latch circuit, a level shifter circuit, and a DA converter circuit, is driven at a high frequency, and hence its shift register circuit and latch circuit have thin gate insulating films and the channel length thereof is shorter than that of the TFT of the buffer circuit.
