Patent number: 9060889Abstract: A stent includes a continuous wave form having a plurality of struts and a plurality of crowns throughout the wave form. Each crown connects two adjacent struts. The wave form is wrapped around a longitudinal axis to define a central portion and two end portions located on opposite sides the central portion. The central portion includes a plurality of turns wrapped around the longitudinal axis and oriented at a first pitch angle relative to the longitudinal axis. The end portions each include a plurality of turns wrapped around the longitudinal axis and oriented at different pitch angles, and an end turn oriented at an angle relative to the longitudinal axis. The different pitch angles of the end portions are between the first pitch angle and the angle of the end turn relative to the longitudinal axis.Type: GrantFiled: January 26, 2010Date of Patent: June 23, 2015Assignee: Medtronic Vascular, Inc.Inventors: Richard Bliss, Justin Goshgarian, Rui Lam, Padraig Savage, Erik Griswold, Gianfranco Pellegrini, Matthew Baldwin, Lance Ensign

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: 8986372Abstract: A delivery device for percutaneously deploying a stented prosthetic heart valve. The device includes a delivery capsule and a recapture sheath. The capsule is configured to compressively retain the prosthesis. The recapture sheath includes a funnel segment having a plurality of circumferentially spaced runners and a polymer overlay. The runners are attached to a shaft and terminate at a distal tip. The overlay surrounds the runners, and is bonded to the shaft but not to at least the tips. The funnel segment is transitionable from a normal condition to an expanded condition forming a funnel shape with a distally increasing diameter, and self-transitionable back toward the normal condition. The funnel segment facilitates sliding of the capsule over a partially deployed region of the prosthesis as part of a recapturing operation. The runners provide columnar strength, with the overlay controlling a shape of the funnel segment.Type: GrantFiled: August 19, 2013Date of Patent: March 24, 2015Assignee: Medtronic, Inc.Inventors: Robert Murry, III, Susheel Deshmukh, Padraig Savage, Matthew Rust

Patent number: 8986375Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the stent which includes a plurality of self-expanding struts and an annular sealing membrane. Each strut has a first end coupled to a distal end of the stent and a second end not coupled to the stent. Each anti-paravalvular leakage component is moveable between a compressed configuration and a deployed configuration. In the compressed configuration, each strut extends distally away from the distal end of the stent. In the deployed configuration, each strut extends proximally away from the distal end of the stent. In an embodiment hereof, the deployed strut has a C-shape and is twisted such that the C-shape lies in a plane substantially along or tangential with the outer surface of the stent. In another embodiment hereof, the deployed strut is rolled-up and extends radially away from the outer surface of the stent.Type: GrantFiled: March 12, 2013Date of Patent: March 24, 2015Assignee: Medtronic, Inc.Inventors: Kshitija Garde, Philip Haarstad, Igor Kovalsky, Stephen Nash, Gianfranco Pellegrini, Finn Rinne, Matthew Rust, Jeffrey Sandstrom, Padraig Savage, William Steinberg

Publication number: 20110071620Abstract: A method of manufacturing a stent includes forming a wave form having a plurality of struts and a plurality of crowns. Each crown connects two adjacent struts. The wave form has a central portion and two end portions located on opposite sides the central portion. Some of the struts located in the end portions have lengths longer and/or shorter than an average length of all of the struts of the wave form. The method includes wrapping the wave form about a longitudinal axis to define a plurality of turns so that an end turn is oriented at an angle relative to the longitudinal axis, a second turn is at a first pitch angle that is less than the angle that the end turn is disposed relative to the longitudinal axis, a third turn is at a second pitch angle that is less than the first pitch angle, and a fourth turn is at a third pitch angle that is less than the second pitch angle.Type: ApplicationFiled: January 26, 2010Publication date: March 24, 2011Applicant: Medtronic Vascular, Inc.Inventors: Richard Bliss, Justin Goshgarian, Rui Lam, Padraig Savage, Erik Griswold, Gianfranco Pellegrini, Matthew Baldwin, Lance Ensign
