MEGA 7.5Fr. & 8Fr. IAB Catheters

The MEGA IAB family offers greater hemodynamic support and higher efficacy for every patient, at any height.

Why are the new sizes better for my patient?

Adding the new 30cc and 40cc MEGA IAB, the benefits of a larger volume IAB are now also available for patients smaller than 5'4" (< 162cm).

Larger volume balloons like MEGA displace more blood in the aorta during diastole, resulting in improved augmentation and unloading. With these new sizing guidelines, a larger patient population can benefit from greater hemodynamic support than ever before. Thus, why not consider using a higher efficacy IAB as your FIRST choice when hemodynamic support is needed?


As the leader in counterpulsation therapy, Maquet is committed to developing IABs that deliver greater hemodynamic support.

 That's why we've built on the exceptional track record of the MEGA 8 Fr. 50 cc IAB to create an expanded MEGA family. With the addition of the larger volume MEGA 7.5 Fr. 30 cc and 40 cc IAB, there's now a balloon that delivers superior blood volume displacement for everyone, at any height.

MEGA: Greater hemodynamic support and higher efficacy for every patient.

Greater hemodynamic support

Larger volume balloons like MEGA displace more blood in the aorta during diastole, resulting in improved augmentation and unloading.*

  • More blood volume displacement
  • More diastolic augmentation 
  • More systolic unloading

STATLOCK® IAB Stabilization Device

All MEGA IABs include two complete and ready-to-use STATLOCK® IAB Stabilization Devices for sutureless securement of IAB catheters, delivering safety and comfort to you and your patients.

  • Eliminates suture-securement needle sticks and suture-wound complications
  • Patient comfort and safety
  • Quick and easy application and removal

Proprietary IAB Membrane

Maquet's patented blow-molded polyurethane material has been developed to withstand the constant abrasion of even the most calcified aortas.

  • 43% more abrasion resistance
  • Reduced insertion force
  • Immediate inflation at start-up

Advanced IAB Design

Additional benefits include:

  • No step-down due to unique balloon wrap
  • Co-lumen design for optimal gas passage
  • Large 0.027" inner lumen for a reliable pressure transducer signal

Case Studies

Enhanced Augmentation of Cardiac Output for Different Counterpulsation Modes Using a New Intra-Aortic Balloon and Catheter

Catalin Boiangiu, MD, Fellow, Division of Cardiology, Newark Beth Israel Medical Center, Newark, NJ; and Marc Cohen, MD, Chief, Division of Cardiology; Director, Cardiol- ogy Fellowship, Newark Beth Israel Medical Center, Newark, New Jersey and Professor of Medicine, Mount Sinai School of Medicine, New York, New York.


We report the enhanced augmentation of cardiac output in a 60-year-old man who underwent percutaneous coronary intervention with drug-eluting stent implantation for a large anteroseptal ST-segment-elevation myocardial infarction. Because of persistent systemic hypotension during the procedure, a 50 cc, 8 Fr. MEGA® intra-aortic balloon was inserted, used for 24 hours, and removed without complications. The use of this new balloon — with larger blood volume displacement but smaller caliber at the insertion site — significantly increased cardiac output in 1:1, 1:2, and 1:3 assist modes, by more than 15%, 9%, and 4%, respectively. These findings exceed the average augmentations reported for smaller-volume balloon catheters.

Improvement in Hemodynamics with a New Larger Volume 50cc IAB for High Risk PCI Study

Pradeep K. Nair, MD, Sun Scolieri, MD, Ashley B. Lee, MD


A primary cause of adverse outcomes among high-risk patients undergoing percutaneous coronary intervention (PCI) may be a diminished capacity to tolerate the hemodynamic and ischemic insults that can occur during the procedure. A common means of mechanical support during PCI has been the intra-aortic balloon pump (IABP). We describe successful periprocedural mechanical support with a new, 50 cc IABP in a patient with both severe left ventricular dysfunction and extensive coronary arteriosclerosis, for whom PCI with stenting was indicated. The prophylactic use of this 50 cc IABP, which traditionally would be contraindicated because of the patient's height (162.6 cm), markedly increased the diastolic aortic pressure (by ~110 mmHg) over the baseline level, while promptly reducing left-sided heart pressures. This finding appears to exceed the average diastolic augmentation reported for smaller-volume balloons. Although the role of the IABP in high-risk PCI remains controversial, further research is warranted to clarify and compare this new 50 cc IABP to smaller-volume balloons, and ascertain whether the observed hemodynamic benefits can translate into improved clinical outcomes among patients requiring mechanical support during PCI.
