New Closure Device for Large Bore Access Procedures

A novel vascular closure device address the complexities of closing the large access punctures required in many advanced cardiovascular interventions.

The MANTA Large Bore Vascular Closure Device is designed to close punctures ranging from 10F to 24F at femoral arterial access sites used during transcatheter aortic valve replacement (TAVR), endovascular treatment of abdominal aortic aneurysms (EVAR), implantation of a ventricular assist device (VAD), and balloon aortic valvuloplasty (BAV). The vascular closure device can be deployed in less than 60 seconds and utilizes an absorbable biomaterial sealing components to plug the access puncture.

Features of the closure device include a rapid fail-safe deployment with immediate hemostasis in order to reduce complications associated with large bore closure, x-ray visibility, and improved control during the deployment procedure. The MANTA Large Bore Vascular Closure Device is a product of Essential Medical (Malvern, PA, USA), and has received the European Community CE mark of approval.

“The MANTA vascular closure device revolutionizes any catheter based transfemoral procedure that requires large-bore arterial access. Access management becomes faster, safer, and reproducible in the hands of many more operators,” said Nicolas Van Mieghem, MD, PhD, medical director of the department of interventional cardiology at the Erasmus Medical Center (EMC; Rotterdam; The Netherlands) Thoraxcenter.

“MANTA should become a mantra when performing TAVI,” said Jan van der Heyden, MD, PhD, of St. Antonius Ziekenhuis (Niewegein, The Netherlands). The Manta is very intuitive to use and provides instant hemostasis. It's a great asset in the lab and will make TAVR cases even more successful going forward.”

Closure of large bore femoral access sites has been associated with significant morbidity, including longer hemostasis times, extended procedure time, the need for a vascular surgeon in the catheterization lab, delayed ambulation, a higher rate of complications, and a higher total cost of care.
