AI Technical Summary
Technical Problem
Current treatment options are lacking for heart failure with preserved ejection fraction (HFpEF) patients, particularly in addressing excessive pericardial constraint that leads to dyspnea on exertion.
Method used
A medical device and method for forming longitudinal incisions in the pericardium using a flexible catheter with an incision device assembly, which reduces pericardial pressure and improves cardiac function.
Benefits of technology
The solution effectively alleviates pericardial constraint, improving cardiac function and reducing symptoms such as dyspnea on exertion in HFpEF patients.

Abstract
A medical device (500) is described and disclosed that includes an incision assembly coupled to the distal end of a catheter (129) and an introducer coupled to and projecting from the incision assembly. Also described and disclosed is a method for improving cardiac function in a subject having cardiac dysfunction, the method including forming at least one incision length through the pericardium and reducing the pressure exerted by the pericardium on the heart.
