IVAM Product Market “High-tech for Medical Devices” at COMPAMED/MEDICA

The focal themes include advanced materials, sensor technologies, systems integration and quality assurance. Another highlight will be the special exhibition on “Electronic Manufacturing Services” (EMS). The Product Market and the forum are organized by the IVAM Microtechnology Network.

Quality management for medical technology products

The measurement of surface texture, finish, roughness, waviness, curvature, and slope of large samples with sub-nanometer accuracy succeeds with the new NPFLEX 3D-metrology system from Veeco Instruments that is based on non-contact, non-destructive white-light interferometric technology. Designed to investigate large and bulky objects, the system utilizes an open gantry that provides full access and allows custom fixing and mounting. The “ContourGT” Product Family is Veecos 10th generation of non-contact, 3D-optical surface profilers and delivers up to 10 times more capacity and throughput improvements in comparison with other systems.

InfiniteFocus, from Alicona Imaging GmbH, is a high resolution optical 3D-measurement system for quality assurance in the lab and in production. In medical device development, the system is commonly used for the measurement of dental implants. In particular, full roughness measurement is of major importance as the implants´ roughness is a decisive factor for its successful, and permanent, adhesion with the jaw bone. This means that also the root of the thread needs to be measured. In contrast to conventional techniques, InfiniteFocus yields repeatable and traceable measurements even at steep flanks, and, consequently, at the root of threads. With the use of focus-variation and the technical principle of the system, the user achieves real based measurements in a vertical resolution of up to 10 nm.

NanoFocus AG presents its flexible and reliable 3D-surface measurement systems for applications in medical technology. The product lines µsurf, µscan and µsprint deliver non-contact measurements in the micro and nanometer ranges as well as analyses according to latest DIN EN ISO parameters. The high precision surface metrology systems are applicable for the measurement of roughness, micro-geometry, topography and layer thickness – from R&D to inline production control. The new µsurf basic confocal microscope will be the center of the exhibitors’ presentation. It is perfectly suited for measurement tasks in support of medical device research, such as wear analyses of dental replica, measuring roughness and surface geometry of dental implant threads, in laser surgery and microfluidics.

Fries Research & Technology GmbH (FRT) offers a comprehensive range of metrological surface measuring systems for the non-destructive investigation of topography, thickness, roughness, abrasion, and many other properties.

Furthermore, interference screws made from a novel calcium phosphate-PLA composite will be displayed. Also, IFAM shows components made from biomimetic modified, hardened biopolymers. All materials can be processed by injection moulding and extrusion processes and 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 2010. 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. SCS’ medical market specialist Lonny Wolgemuth comments: “In addition to parylene coatings, we will also be discussing our new adhesion promotion technologies with visitors.”

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.

Bartels Mikrotechnik GmbH will present micro pumps for infusion therapy at COMPAMED 2010.
In medical applications, such as infusion therapy, micro pumps can be an attractive alternative to standard pumps due to their size, weight and low energy demand. The micro pump “mp6-psense” with its double actuator configuration offers the possibility of an intrinsic flow control. Therefore it can fulfil higher requirements on safety and accuracy under varying conditions as the standard pump mp6. By the controlled loop function the flow can run constantly under varying conditions as pressure, viscosity or temperature changes. The “mp6-psense” will be demonstrated at this years’ exhibition in hall 8a, booth H19.2.

The panel discussion within the forum will focus on key development and integration areas to deliver an integrated health-tech solution: sensor technologies or molecular diagnostics, microfluidics, ICT-enabled instruments and health-record integration. Speakers at the Forum will come from a full range of CD-MEDICS activities, from the lab to healthcare informatics. Prof Ciara O’Sullivan, CD-MEDICS Coordinator, says: "IVAM have provided the opportunity, with the ideal audience, at the right stage in the project lifetime to showcase the next generation of smart diagnostic systems fully integrated into healthcare systems in Europe".

A new development at business unit MICROrun of PARItec GmbH concentrates on micro dosing. The application is a novel method to facilitate early diagnosis of colon cancer. Via an endoscope a few µ litre of a novel optical label are injected in vivo into the tumour. The injection system has to overcome a 200 cm long tube maintaining the precision. The concept, feasibility and the development of this novel micro dosing system are carried out by MICROrun. First tests with functional models were very promising. Besides several versions of micro pump O-run BU MICROrun offers development of customized micro fluidic components and complete systems.
