Patent number: 10500377Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.Type: GrantFiled: October 2, 2018Date of Patent: December 10, 2019Assignee: Edwards Lifesciences CorporationInventors: Pu Zhou, Erik Bulman, Timothy A. Geiser, Michael G. Valdez, Yidong M. Zhu, Baigui Bian, Sonny Tran, Richard D. White, Thanh Huy Le, Tung T. Le, Alpana K. Gowdar, Yong Gao, David D. Williams

Publication number: 20190029820Abstract: An expandable introducer sheath for passage of implant delivery catheters, such as catheters for delivery of prosthetic heart valves. The expandable sheath balances the amounts, shapes and positions of various stiff and elastic structures in the sheath to selectively program the expandability and buckling stiffness of the sheath. The expandable sheath can include, for example, an expandable tubular layer that includes alternating stiff and elastic wall portions of a single radial thickness. The combination of stiff and elastic wall portions allow for torque and push strength to advance the expandable sheath while at the same time accommodating temporary expansion. The expandable sheath can also be reinforced with a tubular layer of braided fibers or a stent structure for additional strength. Other embodiments include selective use of slots or gaps at the distal end of a stiff wall portion to enhance expandability and distribute strain.Type: ApplicationFiled: October 2, 2018Publication date: January 31, 2019Inventors: Pu ZHOU, Yong GAO, Erik BULMAN, Baigui BIAN, Yidong M.

Publication number: 20180177591Abstract: Prosthetic valve embodiments are described herein that include a frame and a valve member mounted within the frame. The valve members can have a plurality of leaflets that are affixed to one another along their inflow edges, with articulating edges projecting from the inflow edges in the outflow direction. In an open configuration, the articulating edges can be collapsed radially inward by the forward flow of blood through the prosthetic valve, thereby creating a plurality of discrete flow areas between the frame and the inflow edges of the leaflets. In a closed configuration, the leaflets can be pushed radially outward by the reverse flow of blood, thereby closing the plurality of discrete flow areas.Type: ApplicationFiled: February 26, 2018Publication date: June 28, 2018Applicant: Edwards Lifesciences CorporationInventors: Michael G. Valdez, Tram Ngoc Nguyen

Patent number: 9675452Abstract: Implantable prosthetic valves are disclosed, methods of their use, and related fabrication techniques are disclosed. In some cases, the prosthetic valves disclosed herein can include frame, skirt, and valve components. The frame component can have an overall, generally scalloped shape comprising fewer struts and fabricated from less raw material than known frames. In some cases, the prosthetic valves disclosed herein can be crimped to a smaller diameter than can other known valves.Type: GrantFiled: October 23, 2015Date of Patent: June 13, 2017Assignee: Edwards Lifesciences CorporationInventors: Michael G. Valdez, Tram Ngoc Nguyen

Publication number: 20160296730Abstract: A delivery sheath includes an elastic outer tubular layer and an inner tubular layer having a thick wall portion integrally connected to a thin wall portion. The inner tubular layer can have a compressed or folded condition wherein the thin wall portion folds onto an outer surface of the thick wall portion under urging of the elastic outer tubular layer. When an implant passes therethrough, the outer tubular layer stretches and the inner tubular layer unfolds into an expanded lumen diameter. Once the implant passes, the outer tubular layer again urges the inner tubular layer into the compressed condition with the sheath reassuming its smaller profile. The sheath may also include selectively placed longitudinal rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion and collapse, thereby reducing the push force needed to advance the implant through the sheath's lumen.Type: ApplicationFiled: October 9, 2015Publication date: October 13, 2016Inventors: Pu Zhou, Erik Bulman, Timothy A. Geiser, Michael G. Valdez, Yidong M. Zhu, Baigui Bian, Sonny Tran, Richard D. White, Thanh Huy Le, Tung T. Le, Alpana K. Gowdar
