Patent number: 11571302Abstract: The disclosure relates to transcatheter stented prosthesis delivery devices including transition elements that route, constrain, support and reduce damage to tension member wear as tension in the tension members is varied to adjust the compression of a stented prosthesis loaded onto the delivery device. Various disclosed tension elements include inserts, edge treatments and guides proximate a distal portion of the delivery device upon which the stented prosthesis is loaded. In some embodiments, the transition feature is positioned proximate a location where at least one tension member transitions from a first orientation that is not parallel to the distal portion to a second orientation that is generally parallel to the distal portion. Further embodiments disclose configurations and methods of selectively locking and unlocking a longitudinal and/or rotational position of the stent frame with respect to the distal portion of the delivery device.Type: GrantFiled: June 25, 2020Date of Patent: February 7, 2023Assignee: MEDTRONIC, INC.Inventors: Michael Gloss, Patrick Griffin, Paul Rothstein, Jeffrey Sandstrom, Brendan Vaughan, Stephen Montgomery, Alan McGuinn

Publication number: 20210177593Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.Type: ApplicationFiled: February 5, 2021Publication date: June 17, 2021Applicant: Medtronic, Inc.Inventors: Joel Racchini, Paul Rothstein, Jeffrey Sandstrom

Publication number: 20210077258Abstract: A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.Type: ApplicationFiled: December 1, 2020Publication date: March 18, 2021Applicant: Medtronic Vascular GalwayInventors: Marian Creaven, Marc Anderson, Kate Corish, Declan Costello, Niall Duffy, Joshua Dwork, John Gallagher, Patrick Griffin, Gavin Kenny, Deirdre McGowan Smyth, John Milroy, Jason Quill, Herinaina Rabarimanantsoa Jamous, Paul Rothstein, Jeffrey Sandstrom, Edmond Sheahan, Frank White
