Patent number: 9333077Abstract: Devices and methods for preparing a transcatheter heart valve system. The device includes a housing, sealing apparatuses and a port. The housing forms a chamber sized to receive a prosthetic valve and a portion of a delivery device. During use, the prosthesis is seated in the chamber, and the sealing apparatuses operated to seal the chamber about the delivery device. Air bubbles in a liquid delivered through the delivery device and to the chamber are removed from the system via the port, thereby flushing the system. Further, the device is manipulated to permit loading of the prosthesis into the delivery device in an air bubble-free environment.Type: GrantFiled: March 12, 2013Date of Patent: May 10, 2016Assignee: Medtronic Vascular Galway LimitedInventor: Stephen Peter

Patent number: 9232994Abstract: A stented prosthetic heart valve including a stent, a plurality of leaflets, and a coupling apparatus. The stent includes a plurality of struts combining to define a generally tubular body, with the struts forming strut segments. The leaflets are mounted to the stent, and include a leaflet provided as part of a first leaflet layer that further forms a tab region. The coupling apparatus is configured for connecting the first leaflet layer to the stent, and includes a backing layer, a guide plate, and a pin. The guide plate and the pin are formed apart from the stent. In this regard, a portion of the backing layer and the tab region are secured between the guide plate and the pin. Further, another portion of the backing layer is attached to at least one of the strut segments to mount the leaflet of the first leaflet layer to the stent.Type: GrantFiled: March 15, 2013Date of Patent: January 12, 2016Assignee: Medtronic Vascular Galway LimitedInventor: Noam Miller

Patent number: 9144493Abstract: The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions.Type: GrantFiled: November 14, 2012Date of Patent: September 29, 2015Assignee: Medtronic Vascular Galway LimitedInventors: Damian Carr, Kate Corish, Niall Duffy, Ronan Rogers, Yossi Tuval, Frank White, Declan Costello, John Gallagher, James Kearns, Edmond Sheahan, Matthew Rust

Patent number: 9023080Abstract: Medical devices and methods for closing an anatomical aperture in a tissue are disclosed. The medical devices can include distal and proximal support structures, which can include a plurality of anchor members. A connection element can connect the distal and proximal support structures, and be configured to twist to create a seal within the medical device. In certain embodiments, a sheath about the medical device can be retracted to expose the distal support structure, which can allow it to revert to an anchoring configuration from a delivery configuration, such that the anchor members can engage an interior surface of the tissue. After twisting the connection element to form a seal, the sheath can be further retracted to expose the proximal support structure, which can allow it to revert to an anchoring configuration from a delivery configuration, such that the anchor members can engage an exterior surface of the tissue.Type: GrantFiled: October 23, 2012Date of Patent: May 5, 2015Assignee: Medtronic Vascular Galway LimitedInventors: Constantin Ciobanu, Evin Donnelly, Frank Harewood, Padraig Savage

Patent number: 8926694Abstract: A dual valve prosthesis having first and second prosthetic valve sections is disclosed. The first prosthetic valve section includes a stent structure with a first prosthetic valve secured therein and the second prosthetic valve section includes an annular frame with a second prosthetic valve secured therein. When the dual valve prosthesis is in an expanded configuration, the annular frame extends from the stent structure such that the first and second prosthetic valves are laterally offset from each other. In a method in accordance herewith, the first and second prosthetic valve sections include prosthetic aortic and mitral valves, respectively, and the dual heart valve prosthesis is configured to replace both the native aortic and mitral valves of the heart in a single transcatheter heart valve implantation procedure.Type: GrantFiled: March 28, 2012Date of Patent: January 6, 2015Assignee: Medtronic Vascular Galway LimitedInventor: Declan Costello
