Maquet Cardiovascular has launched a new Vasoshield Pressure Controlling Syringe for use during coronary artery bypass graft (CABG) surgery in the US. The Vasoshield syringe limits internal 'flushing' pressure and controls vessel distension when harvested grafts are irrigated in preparation for use in bypass surgery.

The Vasoshield Syringe allows the user to select one of three settings 150, 250 or 350 mm Hg so that flushing pressure is adjusted in pre-set increments and uninterrupted flow is delivered during vein preparation. It has been clinically shown that vessels flushed at controlled, lower pressures more effectively overcome spasm, maintain their endothelial and medial layers, and are more likely to provide a high-quality conduit for bypass surgery.

The Vasoshield Pressure Controlling Syringe is part of the Vasoview family of products from Maquet Cardiovascular, which include a range of EVH technology options to perform minimally invasive vessel harvesting procedures.

Patrick Walsh, president of the cardiac surgery business unit at Maquet Cardiovascular, said: “As a leader in the field, Maquet continues to advance cardiac bypass surgery techniques by investing in technologies that help improve patient outcomes and enhance quality of life. The new Vasoshield syringe is yet another example of our commitment to supporting physicians with tools that optimize graft quality and improve standards of care.”

Michael Mack, research director of The Heart Hospital Baylor Plano, is an investigator for the Option (Optimal Improvement of Vein Graft Patency Long Term by the Implementation Of Novel Endoscopic Harvesting Techniques) study. The clinical trial is designed to evaluate the equivalence of Endoscopic Vessel Harvesting (EVH) in CABG surgery compared with historical data for open vein harvesting.

Dr Mack said: “Accurately assessing and controlling pressure in grafts with a standard syringe can be difficult. We look forward to using the Vasoshield syringe because we expect it to assist us in the meticulous handling and preservation of vein grafts, which is vitally important to graft patency and positive patient outcomes.”
