Tulip-Shaped Balloon Catheter for Simple Pericardiocentesis and Percutaneous Pericardiotomy without Fluoroscopy Guidance

Tech ID: sie000289



Pericardiocentesis is a procedure wherein fluid in the pericardium is aspirated. Fluid aspiration is necessary to relieve the pressure on the heart or to analyze the fluid surrounding the heart. When long term drainage is necessary, a cardiothoracic surgeon will create an opening in the pericardium, called a pericardial window, to drain the fluid. The procedure is known as a pericardiotomy or pericardiostomy. A percutaneous balloon pericardiotomy is a percutaneous procedure using a balloon catheter to produce a pericardial window, in effect, by tearing the pericardium with pericardial effusion. The procedure is typically an alternative to conventional pericardiotomy to avoid surgery in patients with a poor prognosis. Generally, the procedure involves having the balloon span across the pericardium and quickly inflating the balloon to create the pericardial window. The procedure is typically performed under fluoroscopic guidance. There exists a need in the art for a device and method for percutaneous pericardiotomy that does not require fluoroscopic guidance and is simpler to perform.


Technology Description

Dr. Robert Siegel from the Cedars-Sinai Medical Center has developed an apparatus to create a pericardial window that comprises a catheter and an inflatable tulip-shaped balloon attached to the catheter. The inflatable tulip-shaped balloon has an axis, a first section that is proximal to the user along the axis, and a second section distal to the user along the axis.



Stage of Development




• Create a pericardial window without the need for surgery or the use of fluoroscopy

• Reduce the level of expertise required to complete procedure

• The catheter may also remain in the pericardium after balloon dilatation for further drainage of fluid from the pericardial space

• Additionally, the catheter may be a braided catheter for additional benefits
