IVAM Product Market "High-tech for Medical Devices" at COMPAMED 2011

The medical device industry continues to be in a primary uptrend, due to a fast growing world population and the demographic transition. COMPAMED, the international leading trade fair for the supplier market of medical manufacturing, opens its doors in the scope of MEDICA from November 16 to 18, 2011 in Düsseldorf, Germany. Experts of the medical technology industry show new developments at the IVAM Product Market and the forum "High-tech for Medical Devices". The focal themes include precision and quality assurance. Product Market and forum are organized by the IVAM Microtechnology Network.

Functional surfaces and advanced materials

The area of Biomaterials Technology at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM shows its expertise in the field of materials and process development for biomaterials at COMPAMED 2011. For example, products with functionalized titanium surface for improved ingrowths of implants will be presented. Furthermore, interference screws made from a novel calcium phosphate-PLA composite will be displayed. Also, IFAM shows components made of bio mimetic modified, hardened biopolymers. All materials can be processed by injection moulding and extrusion processes and can be processed in series with complex geometries. Particular attention is paid to special technologies such as powder injection moulding and manufacturing of micro parts and defined structured surfaces.

Specialty Coating Systems (SCS) will be exhibiting their parylene conformal coating services at COMPAMED 2011. SCS parylene coatings are biocompatible and biostable and offer excellent moisture, chemical and dielectric barrier properties to many medical devices including stents, catheters, pacemakers, needles, mandrels, and elastomeric seals, to name a few. Ultra-thin and perfectly conformal, parylene coatings are ideal for advancing medical technologies.

Chemviron Carbon manufactures Zorflex Activated Carbon Cloth mainly used in wound dressings amongst other medical devices. Zorflex can be impregnated with silver. Recent testing was carried out in an attempt to compare the amount and type of silver leached from 3 different types of silver containing wound dressings. Test results confirmed that the Zorflex containing dressing leached the lowest level of silver compared with the other two dressings. Up to a 91% reduction in the level of leached silver was measured. There was strong evidence to suggest that leached silver from the Zorflex containing wound dressing was nano-particulate and not ionic as per the other two dressings. Alleged cytotoxic effects of silver are associated with entry to the body via silver released into a wound.
