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

Tech ID: sie000289



Pericardiocentesis is a procedure wherein the 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. In instances wherein long term drainage is necessary, a cardiothoracic surgeon will create a pericardial window, in which an opening is made in the pericardium to drain the fluid. The procedure is known as a pericardiotomy or pericardiostomy. Percutaneous balloon pericardiotomy is a percutaneous procedure using a balloon catheter to produce a pericardial window, in effect, by tearing the pericardium in patients 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 and is performed under fluoroscopic guidance to ensure that the balloon spans across the pericardium and that a pericardial window is created. There exists a need in the art for a device and a method for percutaneous pericardiotomy that does not require the fluoroscopic guidance and that may be simpler to perform.


Technology Description

Dr. Siegel from Cedars-Sinai Medical Center developed an apparatus, comprising a catheter, and an inflatable tulip-shaped balloon attached to the catheter, wherein the inflatable tulip-shaped balloon has an axis and comprises a first section proximal to the user being generally conical along the axis, and a second section distal to the user being generally half-spherical along the axis.



Stage of Development




As such, a pericardial window can be created without the need for surgery, or the use of fluoroscopy to determine the location of the catheter or the balloon or to determine whether a sufficient size hole in the pericardium is made. This can be simply done without the need for special expertise.

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

Finally, the catheter may be a braided catheter which present many benefits.
