Publication number: 20230149167Abstract: The present disclosure includes a device for reshaping a heart valve. The device may include a central ring about a central axis and a plurality of arms coupled to the central ring, each of the arms coupled to the central ring at a pivot point at a first end of the arm, the arm comprising an attachment feature at a second point along the arm, the pivot point configured to allow movement of the arm about the pivot point through a plane extending radially from the central axis through the arm. Additionally, the plurality of arms may be contractable and may be extendable such that the hooks extend beyond a dilated heart valve.

Publication number: 20200323616Abstract: Excessive dilation of the annulus of a mitral valve may lead to regurgitation of blood during ventricular contraction. This regurgitation may lead to a reduction in cardiac output. Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The implant may then contract to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the mitral valve and lessening any of the associated symptoms including mitral regurgitation.Type: ApplicationFiled: May 26, 2020Publication date: October 15, 2020Inventors: Randall Lashinski, Matthew Rust, Patrick Macaulay, Terry Wayne Daniels, Kris Kristoffersen

Patent number: 10136985Abstract: Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal or transapical navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The size and/or shape of the implant may then be adjusted, pulling mitral annulus tissue radially inwardly, and restrained in the adjusted configuration to improve mitral valve function.Type: GrantFiled: September 30, 2015Date of Patent: November 27, 2018Assignee: Millipede, Inc.Inventors: Randall Lashinski, Matthew Rust, Patrick Macaulay, Terry Wayne Daniels, Kris Kristoffersen

Patent number: 9622862Abstract: Disclosed is an implantable mitral valve having an adjustable support. The support comprises a plurality of pairs of adjacent struts joined at apexes and a plurality of anchors for tissue engagement. The implant is adjustable to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter for the step of embedding the anchors into tissue surrounding and/or including the mitral valve. The implant may then be adjusted to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the native mitral valve annulus and supporting the prosthetic mitral valve.Type: GrantFiled: September 28, 2015Date of Patent: April 18, 2017Assignee: Millipede, Inc.Inventors: Randall Lashinski, Matthew Rust, Patrick Macaulay, Terry Wayne Daniels, Kris Kristoffersen

Publication number: 20140074148Abstract: A device temporarily positionable within an aortic arch for deflecting embolic particles released during a therapeutic or diagnostic procedure comprises a resilient frame defining an opening and a barrier disposed in the opening. The barrier has a plurality of openings, which may be pores, proportioned to allow passage of blood therethrough but to prevent passage of embolic particles. The barrier has a concave shape having a convex surface positionable in contact with a wall of an aorta to cover at least a brachiocephalic ostium. The frame may include an upstream end including a pair of lobes and an apex between the lobes, and has a generally tapered downstream end.Type: ApplicationFiled: February 21, 2013Publication date: March 13, 2014Applicant: Synecor LLCInventors: Richard A.

Patent number: 7356903Abstract: The present invention is a device for delivering a self-expanding stent. The device has an inner shaft and an outer shaft moveable with respect to the inner shaft. The self expanding stent is received on the inner shaft adjacent its distal end. A tapered tip is located on the inner shaft distal end and it forms a smooth transition from the delivery device to the guide wire extending therethrough. A handle allows the practitioner to deploy the stent single handedly. The stent may have its segments in a first radial configuration for deliver of the stent or the stent may have a plurality of segments in a first radial configuration and a plurality of second segments in a second radial position.Type: GrantFiled: July 30, 2004Date of Patent: April 15, 2008Assignee: Medtronic Vascular, Inc.Inventors: Mike Krivoruchko, William Berthiaume, Don Tran, Kris Kristoffersen, Erik Griswold, Vance Swanson, Somboune Singkeo, Fertac Bilge, Sean Miller
