Patent number: 9066785Abstract: A packaging system is disclosed for shipping a prosthetic tissue valve in a storage solution and preparing and loading of the bioprosthetic valve onto a catheter-based delivery system. The packaging system includes a fluid tight container filled with the storage solution attached to a delivery catheter, wherein the container surrounds the prosthetic tissue valve that is in a pre-loaded position on the delivery catheter during shipment and storage. The prosthetic tissue valve may include an attachment mechanism that attaches to the delivery catheter to properly position the tissue valve for loading within the delivery catheter. In another embodiment where the prosthetic tissue valve is not attached to the delivery catheter during shipment, the attachment mechanism may interact with the prosthetic tissue valve shipping container to prevent the bioprosthetic valve from moving during shipment.Type: GrantFiled: April 6, 2009Date of Patent: June 30, 2015Assignee: Medtronic Vascular, Inc.Inventors: Don Tran, Timothy Ryan, Jeffrey Allen, Melissa Denton, Adam Podbelski

Patent number: 8808370Abstract: A valve loading apparatus is provided for loading a crimped prosthetic valve into a lumen of a delivery system. The valve recoil adapter can counteract recoil of a compressed prosthetic valve, and maintain the valve at its desired crimp diameter. An integrated bioprosthesis/delivery system is provided for delivering a bioprosthesis to a target area within a body lumen is provided. The delivery system includes a valve covering member and a compressing member, which compresses the valve covering member to surround, hold, and/or compress the valve during delivery to the target area.Type: GrantFiled: June 4, 2013Date of Patent: August 19, 2014Assignee: Edwards Lifesciences CorporationInventors: Yaacov Nitzan, Benjamin Spenser, Yaron Keidar, Tamir S. Levi, Melissa Denton Young

Patent number: 7318278Abstract: Methods for forming a support frame for flexible leaflet heart valves from a starting blank include converting a two-dimensional starting blank into the three-dimensional support frame. The material may be superelastic, such as NITINOL, and the method may include bending the 2-D blank into the 3-D form and shape setting it. A merely elastic material such as ELGILOY may be used and plastically deformed in stages, possibly accompanied by annealing, to obtain the 3-D shape. Alternatively, a tubular blank could be formed to define a non-tubular shape, typically conical. A method for calculating the precise 2-D blank shape is also disclosed. A mandrel assembly includes a mandrel and ring elements for pressing the blank against the external surface of the mandrel prior to shape setting.Type: GrantFiled: January 3, 2005Date of Patent: January 15, 2008Assignee: Edwards Lifesciences CorporationInventors: Xiangyang Zhang, Melissa Denton, Sanjay Shrivastava, Pranav Desai
