Become and remain OP(E)N minded!

After more than 10 years available on the market and with more than 60'000 calcified coronary arteries successfully treated (approx. 20'000 within the last 12 months), which means: optimal lesion preparation prior stenting achieved, residual stenosis eliminated, so called undilatable lesions dilated, ISR successfully treated and more; the OPN NC Super High Pressure Balloon has widely proven it`s great effectiveness and safety and it`s large potential for the future for the treatment of complex and calcified lesions. The increasing demand for this product is showing that the convinced community of users is growing fast.

Still, the OPN NC is mainly spelled like O – P – N , this is not the idea! Simply spell it OP(E)N because this is all the meaning in short! " TO OPEN " narrowed arteries to achieve best lesion preparation or postdilatation of suboptimal implanted stents with residual stenosis, treat successfully ISR and more. In order to provide your patients with the best lumen and blood flow for a potentially long lasting and event free result. A very rewarding achievement for your patients, yourself as the responsible operator and for us as developer, producer and marketer of this extraordinary device.

Therefore: "Become and remain OP(E)N minded!"

Thank you for your great work and support!

Yours sincerely

The OPN NC Super High Pressure Balloon (RBP 35bar) success story is continuing

Initially recommended and used for the treatment of so called ''undilatable coronary lesions'' after all other NC balloons have failed (very high pressure dilation for undilatable coronary lesions, Gioel Gabriel Secco) and for post dilatation of stent in highly calcified lesions, it has became an important tool in the armamentarium of the Interventional Cardiologist.

In combination with rotablation in highly calcified lesions (see video sequences below, courtesy of Kambis Mashayekhi, MD, Bad Krotzingen).

Case 1: CTO of LCX

Rotablator wire: 1.5mm burr

Wire exchange to ConfiancaPro and stenting of LCX


DES implantation after rotablation:

Stent not fully expanded

Post dilatation with OPN NC at 50atm

Final result



Case 2:

Note: SIS Medical does not recommend to inflate the OPN NC higher then 35 RBP. The use of extended pressures remains in responsibility of each operator.
