Publication number: 20200229919Abstract: A prosthetic device includes a main body, a first anchor, a second anchor, a first anchor spreader, and a second anchor spreader. The first anchor is coupled to the main body such that a spring force of the first anchor biases the first anchor toward the main body. The second anchor is coupled to the main body such that a spring force of the second anchor biases the second anchor against the main body. The first anchor spreader is coupled to the first anchor such that applying a force to the first anchor spreader moves the first anchor away from the main body against the spring force of the first anchor. The second anchor spreader is coupled to the second anchor such that applying a force to the second anchor spreader moves the second anchor away from the main body against the spring force of the second anchor.Type: ApplicationFiled: April 8, 2020Publication date: July 23, 2020Inventors: Stephen C. Geist, Robert C. Taft, Travis Oba, Sam Sok, Matthew A. Peterson, Kevin M. Golemo, Mark Chau, Seung-Beom Yi

Patent number: 10426606Abstract: A color-coded bioprosthetic valve system having a valve with an annular sewing ring, and a valve holder system with a holder sutured to the ring of the valve, a post operatively connected to the holder, and an adapter sutured to the post and having a color associated with the valve model and/or size. For example, the adapter may be blue to indicate that the valve of the system is a mitral valve of a particular type and/or size. The system may also include a flex handle that is configured to engage with the adapter. The handle has a color associated with the adapter such that a user is able to visually determine that the handle color matches the valve model. For example, the handle may have a grip that is colored blue to match the blue color of the adapter. Accordingly, the color-coded system enables users to confirm easily that the correct accessories such as the sizer or flex handle are being used with the correct valve.Type: GrantFiled: August 23, 2011Date of Patent: October 1, 2019Assignee: Edwards Lifesciences CorporationInventors: Jackie Lau, John Peterson, Grace Kim, John F.

Publication number: 20190167421Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. A preferred embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve portion. The prosthetic valve further comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body. A space is provided between an outer surface of the main body and the ventricular anchor for receiving a native mitral valve leaflet. The prosthetic valve preferably includes an atrial sealing member adapted for placement above the annulus of the mitral valve.

Patent number: 9931207Abstract: 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: GrantFiled: January 19, 2016Date of Patent: April 3, 2018Assignee: Edwards Lifesciences CorporationInventors: Travis Oba, Rafael Pintor, Louis A.

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.

Patent number: 9561100Abstract: 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: GrantFiled: April 10, 2015Date of Patent: February 7, 2017Assignee: Edwards Lifesciences CorporationInventors: Rafael Pintor, Mark Chau, Travis Oba, August R.

Patent number: 9295539Abstract: 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: February 23, 2012Date of Patent: March 29, 2016Assignee: Edwards Lifesciences CorporationInventors: Fred Hodshon, Rafael Pintor, August Yambao, Abhishek Gautam, Louis A.
