Publication number: 20230390062Abstract: Embodiments hereof relate to a delivery system for a transcatheter valve prosthesis, the delivery system having an integral centering mechanism to circumferentially center both the delivery system and the valve prosthesis within a vessel at the target implantation site. The centering mechanism may include expandable wings that may be selectively aligned with openings formed through a sidewall of an outer shaft of the delivery system, a coiled wing that may be selectively exposed through an opening formed through a sidewall of an outer shaft of the delivery system, a plurality of elongated filaments extending through a plurality of lumens of an outermost shaft of the delivery system that may be selectively deployed or expanded, an outer shaft that includes at least one pre-formed deflection segment formed thereon, a tool having a deployable lever arm, and/or a plurality of loops deployable via simultaneous longitudinal and rotational movement.Type: ApplicationFiled: August 18, 2023Publication date: December 7, 2023Inventors: Sarah AHLBERG, Marc ANDERSON, Donna BARRETT, Evelyn BIRMINGHAM, Constantin CIOBANU, Kieran CUNNINGHAM, Paul DEVEREUX, Niall DUFFY, John GALLAGHER, Patrick GRIFFIN, Frank HAREWOOD, Gerry MCCAFFREY, DEIRDRE MCGOWAN SMYTH, Bernard MULVIHILL, Herinaina Rabarimanantsoa JAMOUS, Joel RACCHINI, Jeffrey SANDSTROM, Frank WHITE

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 In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand.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 Upon completion of the stent frame expansion, the tethers are withdrawn.Type: ApplicationFiled: December 1, 2020Publication date: March 18, 2021Applicant: Medtronic Vascular GalwayInventors: Marian Creaven, Marc Anderson, Kate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

Patent number: 8486014Abstract: A balloon dilatation catheter for use in a valvuloplasty procedure includes a catheter shaft and a spiral perfusion balloon mounted thereon. The perfusion balloon is formed from an inflatable tube that is in fluid communication with a catheter shaft inflation lumen. The inflatable tube is coiled into a series of windings that in an inflated configuration form a cylindrical or hourglass profile. In the inflated configuration, inner surfaces of the coiled windings of the inflatable tube define a perfusion lumen to allow blood flow through the perfusion balloon. Adjacent windings may be secured together with a flexible adhesive and/or a support weave formed from one or more filaments of material that criss-crosses between the adjacent windings along substantially the entire length of the spiral perfusion balloon.Type: GrantFiled: March 26, 2011Date of Patent: July 16, 2013Assignee: Medtronic Vascular, Inc.Inventors: John Kelly, Brian Kelly, Herinaina Rabarimanantsoa-Jamous
