Publication number: 20190021858Abstract: The disclosure relates to transcatheter stented prosthesis delivery devices including a handle assembly connected to a shaft assembly on which a stented prosthesis is loaded and compressively retained with a plurality of elongate tension members. The delivery devices include a cutting assembly that can sever the elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient. Certain embodiments position the cutting assembly at least within the shaft assembly and others position the cutting assembly over the shaft assembly. Various disclosed cutting assemblies are actuated with the handle assembly or the like, which draw the tension members across the blade or vice versa.Type: ApplicationFiled: July 18, 2018Publication date: January 24, 2019Applicant: Medtronic Vascular, Inc.Inventors: Alan McGuinn, Paul Devereux, Brendan Vaughan, David O'Toole, Padraigh Jennings, Michael Walsh, Stephen Montgomery, Ronja Pfeiffer

Publication number: 20180318060Abstract: A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.Type: ApplicationFiled: May 2, 2018Publication date: November 8, 2018Inventors: Raymond Ryan, David Clarke, Kshitija Garde, Ya Guo, Benjamin Wong, Yogesh Darekar, Luke Lehmann, Wei Wang, Laura McKinley, Paul Devereux, Joshua Dudney, Tracey Tien, Karl Olney

Publication number: 20180318061Abstract: Aspects of the disclosure relate to “wet” transcatheter prosthetic heart valve or other implant packaging and assemblies in which a prosthetic heart valve or other implant is loaded into a first portion of a delivery device and positioned within a container in which sterilizing fluid is retained to sterilize interior portions of the container as well as provide moisture to prevent the implant from drying out. The disclosure also relates to methods of sterilizing the disclosed assemblies. Some disclosed methods include at least two sterilizing steps and adjustment of a mechanical seal member or formation of multiple seals so that areas proximate the seals are also sterilized during the sterilization process.Type: ApplicationFiled: May 2, 2018Publication date: November 8, 2018Inventors: David Clarke, Karina Doyle, Paul Devereux, Gerry Kearns, Padraigh Jennings, Constantino Fiuza, Stephen Montgomery

Publication number: 20180126127Abstract: Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.Type: ApplicationFiled: November 9, 2016Publication date: May 10, 2018Inventors: Paul Devereux, Paraic Frisby, Frank White, Tomas Kitt, Marc Anderson, Grainne Carroll, Ciaran McGuinness, Tim Jones, Patrick Griffin

Patent number: 8955520Abstract: A dual lumen catheter may be provided with one or more stents in a stent-deployment lumen and a wire guide disposed through a wire guide lumen. The wire guide may be directed to a target site in a patient body such as a biliary stricture. The catheter may be directed along the wire guide until it is in or adjacent the target site. A distalmost stent may be advanced out a distal side-facing aperture of the stent-deployment lumen into the target site by a pusher member that advances the stent or that holds the stent in place while the catheter is proximally withdrawn from around the stent. With the wire guide remaining substantially in place, the stent-deployment lumen can be reoriented and the steps repeated to place a second (and, if desired, subsequent) stent(s) next to—and generally parallel with—the first stent.Type: GrantFiled: July 19, 2012Date of Patent: February 17, 2015Assignee: Cook Medical Technologies LLCInventors: Paul Devereux, Ciarán Toomey, Sharon White
