About project

Our mission is to provide interventional cardiologists with specialized equipment to accurately assess coronary artery lesions.

The company received support as part of the AlfaBRIdge project implemented by the National Center for Research and Development with the participation of the Medi Ventures investment fund.

Innovation in interventional cardiac surgery

The Opti-G guidewire is a diagnostic device that allows precise diagnosis of the nature of the occlusion - neither angiography, which is an X-ray device that shows the course of the vessels after contrast is injected into the arterial lumen, nor cardiac CT or, even less, MRI give any feedback on the nature of the occlusion. Direct assessment is the way to simplify the procedure, shorten its duration and reduce the complications associated with the operators' learning curve. The Opti-G guidewire is primarily intended for use during interventional procedures for coronary artery disease



An effective analysis of the nature of the occlusion causing the blockage in the coronary artery will allow a crucial decision to be made on the choice of the procedure, the appropriate devices and the need for any revascularization. This is crucial because of the adequate patency of the vessel and the subsequent life of the patient. Coronary CTO is still the last barrier to complete percutaneous revascularization of patients with coronary artery disease, mostly due to technical considerations. Difficulty and complexity of recanalizing CTOs with percutaneous techniques results from a lack of information on the characteristics of the occlusion

Background Of Idea

According to WHO reports cardiovascular diseases are the most distributed cause of death worldwide. Coronary Chronic Total Occlusions (CTOs) are commonly findings during routine coronary angiography with a prevelence betweenen 18% and 52%. Percutaneous angioplasty intervention of CTO has the potential to offer patients several benefits including symptom relief, improvement in left ventricular function and better long term survival
