Tartalmi leírás:
Revascularisation by endovascular implant (stent) has great importance in the treatment
of coronary artery diseases. Stents are high-technology implants that are the creation of the
knowledge of health sciences, physics, chemistry, material science and engineering. Its
development can be carried out only by the involvement of these areas of knowledge. Hungary has
a stent production since 1995, which is the only one in the new EU member countries. The aim of
the project that has been started within the frameworks of the National Research and Development
Program, is the development of a new stent family based on the results of the material science
researches have started for 10 years and the clinical and production experiences of experts, which
could result an equivalent Hungarian product to the market leader products in case of several product
lines. The original wire-mesh cut for those replaced welded stents made of wire later from tubes
laser cutted ones. The stents are made of biocompatible materials: 316LVM stainless steel, Co-Cr
alloys and nitinol. Stents made from wires are produced by weaving, or reeling and resistance projection
welding. Nowadays, stents are produced mostly by high-precision laser cutting. These were
large steps forward in the development of production technology, following the appearance of
balloon catheters. Independently of what kind of manufacturing process is used, it has to be very
precise because a connecting goal of the development is to increase the biocompatibility of the
stents with surface treatment and to create a coating that is able to carry drug on the smooth surface.
The paper presents the antecedents, achievements and main future objectives in micro
manufacturing speciality of that special medical device, that is just before the surface treatment and
coating process of the stent.
