Publication number: 20240122705Abstract: A prosthetic cardiac valve comprises an anchor having an atrial skirt, an annular region, and a ventricular skirt. The prosthetic valve also has a plurality of prosthetic valve leaflets each having a first end and a free end. The first end is coupled with the anchor and the free end is opposite the first end. The prosthetic cardiac valve has an open configuration in which the free ends of the prosthetic valve leaflets are disposed away from one another to allow antegrade blood flow therepast, and a closed configuration in which the free ends of the prosthetic valve leaflets engage one another and substantially prevent retrograde blood flow therepast. The anchor has a collapsed configuration for delivery to the heart and an expanded configuration for anchoring the prosthetic cardiac valve to a patient's heart.Type: ApplicationFiled: December 20, 2023Publication date: April 18, 2024Applicants: Neovasc Tiara Inc., Neovasc Inc.Inventors: Matthew Randy Lane, Colin A. Nyuli, Jeremy Brent Ratz, Arshad Quadri

Patent number: 11633279Abstract: Methods for delivering a replacement heart valve include advancing a delivery system through a femoral vein and into the atrium of a heart, wherein the delivery system includes an outer sheath assembly, a mid shaft assembly and an inner assembly. The outer sheath assembly and the mid shaft assembly are adapted to retain the replacement heart valve in a radially compacted state over the inner assembly. The outer sheath assembly is retracted to allow a plurality of distal anchors to self-expand while a portion of the replacement heart valve remains retained in a compacted state by the mid shaft assembly. The distal anchors are positioned to engage one or more native leaflets and the retained portion of the replacement heart valve is then released and allowed to fully expand for implanting the replacement heart valve within the native valve.Type: GrantFiled: March 19, 2021Date of Patent: April 25, 2023Assignee: Edwards Lifesciences CardiAQ LLCInventors: Glen T.

Publication number: 20160143733Abstract: A replacement heart valve has an expandable frame configured to engage a native valve annulus and a valve body mounted to the expandable frame. The valve body can have a plurality of valve leaflets configured to open to allow flow in a first direction and engage one another so as to close and prevent flow in a second direction, the second direction being opposite the first direction.Type: ApplicationFiled: January 29, 2016Publication date: May 26, 2016Inventors: Arshad Quadri, Jeremy Brent Ratz, Robrecht Michiels
