Publication number: 20250205048Abstract: A method of implanting a prosthetic heart valve may include inserting a delivery catheter into a patient's vasculature while the prosthetic heart valve is in a crimped condition on the delivery catheter. The delivery catheter may be advanced through the patient's vasculature until the crimped prosthetic heart valve is positioned within a native valve annulus. While the prosthetic heart valve is within the native valve annulus, a first stage of deployment may be performed in which the balloon is inflated at a first rate of inflation to begin expanding the prosthetic heart valve. After performing the first stage of deployment, a second stage of deployment may be performed in which the balloon is inflated at a second rate of inflation that is greater than the first rate of inflation. After performing the second stage of deployment, the prosthetic heart valve may be anchored within the native valve annulus.Type: ApplicationFiled: November 21, 2024Publication date: June 26, 2025Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Michael Shane Morrissey, Robert Schulzetenberg, Neil Theisen, Abhijeet Joshi, Peter J.
