iVascular is a fast growing company founded in 2010 in Barcelona (SPA) with the aim of developing advanced medical devices and therapies for the treatment of disorders of the cardiovascular system. The team that started iVascular owns more than 20 years of experience in the field of cardiovascular devices, being responsible of achieving one of the first CE marks for a drug eluting stent more than 12 years ago.
iVascular was born to become a reference in the cardiovascular field by empowering the value of technology. Our staff provides extensive knowledge in biopolymers, coatings, drug delivery, mechanical engineering, medicine and pharmacy. They bring together recognized experience in the development of medical devices and implants.
The purpose of iVascular is to develop innovative advanced medical devices and therapies for the treatment of disorders…www.ivascular.global
How is a stent implanted?
The patient is taken to the Hemodynamic laboratory and a cardiac catheterization and coronary artery. Once the catheter is in the coronary arteries, contrast is injected and the places where the arteries are narrowed are seen. Then, angioplasty of the coronary artery is performed: a balloon is inserted into the femoral artery through a puncture in the groin and taken to the heart (x-ray guided). When the balloon is inflated into the coronary artery, the narrowed area is dilated and blood flows normally. After balloon inflation, the coronary stent is placed so that the artery remains permanently open. In most cases, the patient is discharged between 24 and 48 hours after the procedure.
Types of stents
Conventional stent, usually steel or chrome-cobalt.
Drug-coated stent or drug releasers (pharmaco-active stent). It provides the same structural support as conventional stents, but is also designed to slowly release the exact dosage of the drug and thus help prevent restenosis (the reproduction of narrowing of the artery). After the implantation of this type of stent, it will be necessary to carry two antiaggregating drugs (to make the blood more fluid) — acetylsalicylic acid (aspirin) and clopidogrel — for at least 1 year.
Bioabsorbable pharmacoactive stents. Same as above, but over time they are able to reabsorb part of their structure or disappear completely (including metal). Their advantage is based on the probability that by “dissolving” they would allow a complete restoration of all functions of the artery wall, avoid late mechanical problems and facilitate visualization and non-invasive assessment during follow-up of the treated coronary segments.
The choice of one type of stent or another depends on the patient’s characteristics (such as the risk of bleeding), type of coronary lesions, etc. The stent implant physician (hemodynamic cardiologist) will consider the patient’s characteristics and decide what type of stent to put on the patient.
