A medical device for treating a heart valve insufficiency, with an endoprosthesis which can be introduced into a patient’s body and expanded to secure a heart valve prosthesis in the patient’s aorta with a catheter. The management information writing unit is configured to update, when the storage position of data is changed in the nonvolatile memory, the management information stored in the volatile memory. The system has a microprocessor based controller and can kill Clostridium difficile and other pathogens to thereby decontaminate items in 30 seconds or less. In one version the first and second legs and the strip are all on the third surface. This epoxy resin composition in this invention can achieve the peeling strength>10 lbfinch, glass transition temperature>155, water absorption<0. The float arm pivots upon the valve body about an integral trunnion bar to permit selective engagement of the valve seal with the valve seat.
