Joining two plastics components of a medical device - - using intermediate metal part between components and then melt form

摘要

Process for joining two separate components of a medical device (e.g. a catheter) consisting of similar plastics material, is characterised by shaping the components to be joined in such a way that they fit in to each other; placing a metal part between the fitted components; placing the whole into an induction heating device; applying heat of induction to the ends of the components and the metal part so as to heat same and soften the overlapping ends; removing the components from the heating device; and cooling so as to effect a medically acceptable joint.
