Percutaneous transluminal coronary angioplasty (PTCA) is a method used to dilate occluded coronary blood vessels, stents are often used in addition to prevent sudden early vessel closure and to reduce the possibility of restenosis (re occlusion of the vessel. Problems are faced in the reliability of the stents used. Current type stents have some design and material problem which make theme hard to place and often need additional treatment to keep them in place or even remove theme again. Problems are also on the expenses budget. Hospitals use usually more then 1 catheter per patient. Due to treating more diseased vessels or placing a stent after dilation. The current balloons types do not refold enough to be used more then once. Since budgets are under pressure in Europe there is not sufficient funding to do all needed treatment. Therefore Occam has conceptualised a balloon catheter system which consists of three parts: a re usable shaft (the proximal patt). a disposable balloon section (distal part) and a new t,spe of stent. Balloon catheters are predominantly single use products. In Occam?s concept, the shaft is a tool to deliver the balloon to the stenosed arca. Since the shaft will be made of metal it can be re sterilised and re used many limes while the balloons themselves can be disposed of after each procedure. The balloon and the shaft will be kept together with a connector. The balloon needs to have better refolding characteristics without loosing the current market standards demands, so it can be used more than once on the same patient. The concept of the stent is to use a design which is easy to place and keeps it strongly fit into the vessel.
