Publication number: 20250009508Abstract: A heart valve therapy system includes 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 In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand.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 Upon completion of the stent frame expansion, the tethers are withdrawn.Type: ApplicationFiled: September 16, 2024Publication date: January 9, 2025Applicant: Medtronic Vascular GalwayInventors: Marian Creaven, Marc Anderson, Kate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

Patent number: 11801137Abstract: Methods of deploying and securing a heart valve prosthesis are disclosed. A heart valve prosthesis having a plurality of anchor guides is loaded within a catheter-based delivery device, wherein each of the anchor guides is releasably engaged by a respective elongate member and wherein tensioning of the elongate members aids in collapsing the prosthesis during loading. The delivery device is advanced via a transcatheter procedure to position the heart valve prosthesis at an implantation site. The heart valve prosthesis undergoes controlled deployment by controlling the release of tension on the elongate members. After deployment of the heart valve prosthesis, an anchor tool is advanced along at least one elongate guide member to the anchor guide associated therewith and positioned at a securement site. When the securement site is reached, an anchor clip is released from the anchor tool to secure the prosthesis to the heart.Type: GrantFiled: February 7, 2020Date of Patent: October 31, 2023Assignee: Medtronic Vascular, Inc.Inventors: Niall Duffy, Joshua Dwork

Patent number: 11786370Abstract: Systems for delivering prosthetic heart valve devices can include, for example, an elongated catheter body, a deliver capsule carried by the catheter body, and an expandable atraumatic member. The delivery capsule includes a platform and a housing having an outer wall and a proximal rim, and the platform is configured to be releasably coupled to a prosthetic heart valve device. The housing is configured to slide along the platform from a containment configuration to a deployment configuration. The expandable atraumatic member has an atraumatic surface and a peripheral portion. The atraumatic member has a compacted configuration and an expanded configuration in which the peripheral portion extends laterally outward over the proximal rim of the housing to protect tissue of the heart and the vasculature from potentially being damaged by the proximal rim of the housing as the delivery system is withdrawn in a proximal direction through the patient.Type: GrantFiled: October 5, 2020Date of Patent: October 17, 2023Assignee: Twelve, Inc.Inventors: Kevin Mauch, Joshua Dwork, Finn Rinne, Siyan Som, Estella Wong
