CTSO Overview

Cytosorbents Corporation specializes in creating and bringing to market innovative medical devices. Their core expertise lies in a unique blood purification platform, built upon a proprietary adsorbent and porous polymer technology. The company's leading product, CytoSorb, is an extracorporeal filter designed to remove cytokines from the blood. It serves as a complementary treatment in various critical care scenarios, including sepsis, managing complications during and after heart bypass surgery, and improving the viability of donor organs for transplantation. Beyond CytoSorb, Cytosorbents offers a portfolio of specialized devices. These include VetResQ, used to assist in treating critical conditions like sepsis and pancreatitis in animals; CytoSorb-XL, another device targeting sepsis and other severe illnesses; HemoDefend, a platform for purifying blood supplies by removing contaminants that cause transfusion reactions and diseases, as well as anti-A and anti-B antibodies from blood products; K+ontrol, designed for patients with severe, life-threatening hyperkalemia; and ContrastSorb, which extracts intravenous contrast agents following imaging procedures (like CT scans, angiograms, or interventional radiology) to mitigate the risk of contrast-induced kidney damage. The company is also actively developing several new solutions: BetaSorb, aimed at preventing and treating complications from metabolic toxin buildup in chronic kidney disease patients; DrugSorb, which focuses on eliminating harmful chemicals from the bloodstream; and DrugSorb-ATR, an innovative system for removing antithrombotic agents. Originally established as MedaSorb Technologies Corporation in 1997, the company adopted its current name, Cytosorbents Corporation, in May 2010. Its corporate headquarters are situated in Princeton, New Jersey.
