Publication number: 20240004959Abstract: Systems of quickly and easily implanting a quick-connect heart valve prosthesis during a surgical procedure are provided. The heart valve may include a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A system and method for deployment includes an integrated handle shaft and balloon catheter. A safety member disposed between the balloon catheter and handle shaft prevents premature catheter advancement prior to heart valve placement at the annulus, and also may prevent premature balloon inflation prior to full catheter advancement.Type: ApplicationFiled: September 14, 2023Publication date: January 4, 2024Inventors: Andrew Phung, August R. Yambao, Faisal Kalam, William C. Brunnett, Rafael Pintor, Michael J. Scott

Publication number: 20230084393Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.Type: ApplicationFiled: November 17, 2022Publication date: March 16, 2023Inventors: Rafael Pintor, Mark Chau, Travis Zenyo Oba, August R. Yambao, Louis A. Campbell, Tammy Huntley, Qinggang Zeng, Carey L. Cristea, Faisal Kalam

Publication number: 20230072121Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.Type: ApplicationFiled: October 13, 2022Publication date: March 9, 2023Inventors: Rafael Pintor, Michael J. Scott, Thomas Chien, Harvey H. Chen, August R. Yambao, Lawrence J. Farhat, Andrew Phung, William C. Brunnett, Carey L. Cristea, Sara M. Walls, Kevin W. Zheng, Faisal Kalam, Qinggang Zeng

Patent number: 11311378Abstract: Packaging for prosthetic heart valves including an assembly for securely retaining a heart valve within a jar and facilitating retrieval therefrom. The assembly includes a packaging sleeve that fits closely within the jar and has a clip structure for securing a valve holder. Contrary to previous designs, in one embodiment the valve holder is directed downward into the jar, and the valve is retained with an inflow end upward. The valve may have flexible leaflets, and a leaflet parting member on the end of the shaft extends through the leaflets and couples with the valve holder. The assembly of the packaging sleeve, valve, and holder can then be removed from the jar and a valve delivery tube connected with the holder, or to the leaflet parting member. The packaging sleeve may be bifurcated into two halves connected at a living hinge to facilitate removal from around the valve/holder subassembly.Type: GrantFiled: June 22, 2020Date of Patent: April 26, 2022Assignee: Edwards Lifesciences CorporationInventors: Frederic B. Hodshon, Rafael Pintor, August R. Yambao, Abhishek Gautam, Louis A. Campbell, Lawrence J. Farhat, Tammy Huntley, Faisal Kalam, Travis Zenyo Oba, Qinggang Zeng

Publication number: 20210353408Abstract: A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.Type: ApplicationFiled: July 30, 2021Publication date: November 18, 2021Inventors: Harvey H.
