Acute Percutaneous Ventricular Assist Device

Leveraging our deep expertise in VADs, Minnetronix has developed an innovative percutaneous ventricular assist device (pVAD) concept that addresses the current market gap for a high flow, easily deployed device.

The Challenge

In the United States today, more than 100,000 critically ill patients need temporary circulatory support due to various cardiac conditions, such as acute myocardial infarction, cardiogenic shock, heart failure, or high-risk cardiac interventions. Many of these patients receive support through an intra-aortic balloon pump (IABP), which can be quickly deployed to help increase cardiac output. However, IABPs do not provide enough blood flow for many critically ill patients. Other percutaneous ventricular assist devices (pVADs) exist that supply higher rates of blood flow, but such devices are often complex and time-consuming to deploy. As a result, physicians have identified a critical need for an acute mechanical circulatory support device that can provide higher flow rates yet is rapid and straightforward to deploy.

Minnetronix’ history in mechanical circulatory support officially dates back to our inception and our very first program in 1996. Since then, we have developed a deep body of knowledge and understanding of unmet clinical needs in the field of circulatory support. This work and expertise led our engineering team to the development of our own proprietary concept for an acute percutaneous ventricular assist device.

The Solution

Minnetronix' pVAD Technology in Situ

Minnetronix has developed a high-quality, affordable, and relevant pVAD solution. Our proprietary concept consists of a collapsible catheter and impeller that is expanded post-deployment. Once deployed, the impeller has a comparatively large surface area, which allows the device to take in more blood and provide a higher flow rate. Our device is designed to provide a high flow rate at low impeller revolutions per minute.

Minnetronix' pVAD Catheter and Impeller

Minnetronix owns issued patents that protect our expanding/collapsing catheter concepts, including:

  • US 8,734,331 B2: Expandable blood pumps and methods of their deployment and use
  • US 8,849,398 B2: Expandable blood pump for cardiac support

The Result

Minnetronix’ pVAD technology is designed to address the current gap in the market for a high flow, easily deployed device. Physicians are excited about our proposed device as it is intended to provide sustained cardiac output (>5 liters/min), direct ventricular unloading, and reduced complications. Other potential advantages include:

  • Small catheter size
  • Ease of insertion
  • Traditional femoral access
  • Price point to enable wide adoption
