HeartMate II

Left Ventricular Assist Device


Proven Results for Long Term Support

The HeartMate II™ Left Ventricular Assist Device (LVAD) provides short or long-term circulatory support for intermediate-to-advanced heart failure patients. This small, quiet pump features a simple design — with only one moving part — and can provide blood flow equivalent to that of a healthy heart.

Over 27,000 patients implanted with the HeartMate II LVAD1

Unparalleled real-world experience

The HeartMate II LVAD is indicated for both destination therapy and bridge-to-transplantation in the United States. Additionally, HeartMate II LVAD is backed by more than 10 years of clinical experience.2

To date, more than 27,000 heart failure patients have received the HeartMate II LVAD.1 Many have passed the 5-year milestone on therapy, with some still on therapy after 15-plus years.1 These figures offer more than a decade of living proof that HeartMate II LVAD delivers predictable surgical and clinical performance for improved outcomes.3-8

Many patients have lived more than 15 years with HeartMate II LVAD1

Proven Long-Term Patient Outcomes

Research has shown the HeartMate II LVAD:

  • Reverses and sustains reduction of heart failure symptoms8
  • Increases patients’ survival rates and quality of life compared with medical management alone9

Predictable Performance for Improved Outcomes

Outstanding Two-Year Survival

HeartMate II LVAD has shown a 76% 2 year survival rate

Significant Improvement in NYHA Class

77% improvement to NYHA 1 or 2 from NYHA 3 or 4 at 6 months with improvements sustained through 24 months.

Significant Increase in 6-Minute Walk Distance

At baseline, patients who were tested completed the 6-minute walk test at an average of 129 meters. At 2 years after HeartMate II LVAD implant, patients completed the test at an average of 361 meters. That's two and a half times as far, for a 150% improvement in distance.8

Reduction in Thrombus with Adherence to PREVENT Guidelines

PREVENT Guidelines are a set of clinical and surgical recommendations that are aimed at maximizing flow through the LVAD, reducing risk of cannula malposition, and ensuring that the patients are adequately anti-coagulated while on LVAD support.

4.8% confirmed pump thrombosis events at 6 months for the HeartMate II LVAD

Patient-Centric Features

The HeartMate II LVAD is designed for patient comfort and convenience. With its wearable design and several carrying options, the HeartMate II LVAD supports your patients’ lifestyles.

Other features and benefits:

  • Mean blood flow of up to 10 L/min—equal to that of a healthy heart
  • Low-dose anticoagulation regimen
  • Safe for air travel*

Safety by Design

The HeartMate II LVAD comes with a lightweight, pocket-sized controller that interfaces with the implanted pump.

Its features are designed for safety:

  • Backup battery provides at least 15 minutes of full power in an emergency situation
  • Prioritized visual alarms provide clear, actionable instructions
  • On-screen instructions eliminate the need for guesswork
  • Driveline diagnostic checks verify that driveline wires are intact and functional
