Novel Cardiology Access Tool for Single Incision Percutaneous Procedures


Novel cardiology tool
Novel cardiology access tool
Researchers at Children's National Hospital have developed a novel surgical tool for implanting cardiac therapy devices, obviating the need for invasive open chest surgery procedures.



Each year, nearly 7,200 infants in the United States are born with complex congenital heart disease that requires surgical intervention. To deliver cardiac therapy, children currently undergo a sternotomy or thoracotomy to expose the epicardial surface of the heart. This open chest surgery is highly invasive, and typically includes stays in the intensive care unit. Our novel access tool converts an open chest surgery to a minimally invasive, single incision, percutaneous procedure. This brings the following advantages to the cardiac therapy device field:

  1. Reduces collateral tissue damage, minimizes post procedure pain and shortens recovery time.
  2. Patient safety: our tool provides direct visualization of the heart so the operator avoids damage to coronary arteries and other key epicardial structures.
  3. No fluoroscopy; a radiation-free procedure.
  4. Ease of use will lead to quick adoption by healthcare providers.


  • Various adult markets, including accessing new pacing sites
  • Pediatric patients with arrhythmias
  • Deliver ablation therapy to the epicardial surface, directly visualize the ablated region
  • Deliver stem cell or injectable therapies to the pericardial space under direct visualization

Stage of Development

  • Animal studies performed. Preclinical studies ongoing.

Intellectual Property Status

  • Patent applications “Delivery Tool and Method for Devices in the Pericardial Space” filed in U.S., Europe, Canada, Australia
