Publication number: 20240173125Abstract: Some embodiments described herein include a heart valve replacement system that may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, a prosthetic heart valve of the system includes structural features that securely anchor the prosthetic heart valve to the site of the native heart valve. Such structural features can provide robust migration resistance. In particular implementations, the prosthetic heart valves occupy a smaller delivery profile, thereby facilitating a smaller delivery catheter for advancement to the heart.Type: ApplicationFiled: January 31, 2024Publication date: May 30, 2024Inventors: Ramji Iyer, Lucas Tradd Schneider, Gunnar Paul Askegaard

Publication number: 20240173120Abstract: Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile, thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment of the prosthetic heart valve to a native tricuspid valve site via a superior vena cava or inferior vena cava.Type: ApplicationFiled: February 2, 2024Publication date: May 30, 2024Inventors: Gunnar Paul Askegaard, Lucas Tradd Schneider, Ramji Iyer

Patent number: 11969188Abstract: Devices used to deploy transvascular medical device systems and methods for using such devices are described in this document. For example, this document describes dilating introducer devices used for the percutaneous vascular deployment of catheter-based medical devices such as structural heart medical devices. Such dilating introducer devices can facilitate the percutaneous vascular deployment of catheter-based medical devices without an additional introducer sheath.Type: GrantFiled: September 18, 2023Date of Patent: April 30, 2024Assignee: Laplace Interventional Inc.Inventors: Nathaniel Thomas Smith, Gunnar Paul Askegaard, Lucas Tradd Schneider, Ramji Iyer
