Patent number: 12376963Abstract: 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 valves are implanted using catheter-based deployment systems that include multiple control wires. In particular implementations, the deployment systems can include a retrieval catheter that can be used to recapture the prosthetic heart valve back into a delivery sheath after being expressed from the delivery sheath. The prosthetic heart valves can include a plurality of optional suture knots to enhance migration resistance. Some delivery catheter systems can include a controllably bendable control catheter and/or a deflectable 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: GrantFiled: May 9, 2025Date of Patent: August 5, 2025Assignee: Laplace Interventional Inc.Inventors: Rachel Jean Anderson, Lucas Tradd Schneider, Gunnar Paul Askegaard, Daniel Oliver, Ramji Iyer

Publication number: 20250073021Abstract: 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: November 15, 2024Publication date: March 6, 2025Inventors: Gunnar Paul Askegaard, Lucas Tradd Schneider, Ramji Iyer
