摘要：
A hydrogel coupling device for the transmission of ultrasound therethrough having a predetermined shape and comprising a hydrogen bonded composition comprising PVA, one or both of PVP and PEG, and the balance water. The predetermined shapes are formed and are then exposed to (a) one or more freeze/thaw cycles, (b) one or more dehydration/re-hydration cycles, or (c) one or more freeze/thaw cycles and one or more dehydration/re-hydration cycles. The shapes may further be irradiated with high energy radiation followed by heat treating.
