The aim of this work was to develop a new and versatile method for welding
thermoplastics using microwave energy. A multimode cavity applicator was de
veloped including features designed to deliver an even energy density and t
o apply weld pressure. A review of possible microwave susceptible implant m
aterials was undertaken and results of welding trials using several candida
te materials showed that this is a feasible welding technique. (C) 2001 Klu
