Looking for angiography producers

It is about 8 years we have been working in the field of cardiovascular and interventional products and we have been successful too. In this part we have been worked with Calmed in USA in coronary cannula , with Eurosets in Italy in arterial filters and oxygenators and Infomed company with hemofilters , with Dispomed in disposable products
We have been working with Ansamed in interventional part and purchase them annually about 80,000 catheters, but since this company products are not complete
