Manufacturing defects in polymeric medical devices

P.R. Lewis,     The Open University, UK

Abstract:

Injection Moulding, extrusion and other processes for manufacturing polymer components are discussed. Several case studies are presented where manufacture of polymer components is crucial to product performance, such as injection-moulded polycarbonate connectors in a catheter, cylinder guard fractures, sight tubes, a crutch failure, and ozone cracking of tubing and a condom.
