The present invention provides an aberration correction device. The device separates the valve and the surrounding area from the rest of the vascular system so the operation procedure can be carried out while the heart is beating during the entire course of the procedure. The hologram plate 42 is a multilayer structure made up of a first transparent substrate 31, a hologram layer 32, an adhesive layer 33 and a second transparent substrate 41. In a telecommunication system, this substantially simultaneous transmission of the first and second data using a similar carrier frequency in a radio frequency communication over a wireless local area network may increase throughput of a downlink, for example, by a factor nominally equal to the number of antennas at an access point. A rear part of an upper edge of a carrier basket is connected to the basket-holding rods.
