There is provided a method to modify biodegradable polymers using the direct reaction of a biodegradable polymer in a vinyl monomer and may take place in the presence of initiators. As a computer detects a change in the network to which it is connected, the computer obtains configuration information associated with the newly detected network. Logic is further arranged to transmit error free application data back to the host application process prior to performing error correction; and store in memory only application data in which errors are detected. With the driving roller rotating at the set rotating speed, a printing process is performed so that a transfer belt turns at a constant running speed. Accordingly, in the device 10 the method, and the antenna one or both of the center frequencies can be changed to permit operation at more than two frequencies. In an additional embodiment, the methods are useful for performing an edge to edge bow-tie repair on cardiac valve tissues.
