Patent number: 9901448Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable coupling stent, 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 coupling stent attached thereto. The coupling stent 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 a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.Type: GrantFiled: April 13, 2015Date of Patent: February 27, 2018Assignee: Edwards Lifesciences CorporationInventors: Rafael Pintor, Mark Chau, Travis Oba, August R. Yambao, Louis A. Campbell, Tammy Huntley, Qinggang Zeng, Carey L. Cristea, Faisal Kalam

Patent number: 9877831Abstract: A system for expanding a device in a conduit or orifice of a human body includes a balloon member that is movable from a first configuration to a second configuration. External surfaces of the balloon member can collectively have a non-cylindrical cross-section relative to a main axis of the balloon member, such that the external surfaces of the balloon member generally conform to the anatomical shape of the conduit or orifice when the balloon member is in the second configuration.Type: GrantFiled: April 12, 2016Date of Patent: January 30, 2018Assignee: Edwards Lifesciences CorporationInventors: Mark Chau, Travis Zenyo Oba, Tammy Huntley, Qinggang Zeng, August R.

Publication number: 20170296336Abstract: 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: February 2, 2017Publication date: October 19, 2017Applicant: Edwards Lifesciences CorporationInventors: Rafael Pintor, Mark Chau, Travis Zenyo Oba, August R.

Publication number: 20170224484Abstract: 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: November 23, 2016Publication date: August 10, 2017Inventors: Rafael Pintor, Michael J.

Publication number: 20160262882Abstract: 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: ApplicationFiled: March 11, 2016Publication date: September 15, 2016Inventors: Fred Hodshon, Rafael Pintor, August R.

Publication number: 20160128829Abstract: An exemplary two-stage prosthetic heart valve system has a radially expandable base stent implanted within a native valve annulus. The two-stage heart valve system also has a valve component that is delivered to and mounted within the base stent in a separate or sequential operation after the base stent has been anchored within the annulus. The valve component in certain embodiments comprises a hybrid valve component that includes a conventional, non-expandable surgical valve that is modified to include an expandable coupling stent that can be expanded to engage the inner surface of the base stent, thereby anchoring the valve component to the base stent. In its expanded configuration, the outflow end portion base stent has tri-lobular shape that closely conforms to the shape of the aortic root and a support ring of the prosthetic valve that is mounted within the base stent.Type: ApplicationFiled: January 19, 2016Publication date: May 12, 2016Inventors: Travis Oba, Rafael Pintor, Louis A.
