Patent number: 10449042Abstract: 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: GrantFiled: August 22, 2017Date of Patent: October 22, 2019Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Colin A.

Patent number: 10433952Abstract: A prosthetic mitral valve may be anchored in a native mitral valve. The prosthetic mitral valve preferably has a large anterior prosthetic leaflet that spans the entire width of the native anterior leaflet and the anterior prosthetic leaflet moves away from left ventricular outflow tract during systole to create a clear unobstructed outflow path.Type: GrantFiled: January 27, 2017Date of Patent: October 8, 2019Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Karen Tsoek-Ji Wong, Ian Fraser Kerr, Mark Segal

Patent number: 10383728Abstract: A method for delivering a prosthetic valve to a patient's heart having a native valve with a plurality of valve leaflets includes providing a delivery device with a prosthetic valve, advancing the delivery device toward the native valve, and expanding a portion of the prosthetic valve to form a flanged region that is upstream of the valve leaflets. One or more tabs on the prosthetic valve are released so that they expand outward to a position that is transverse to the longitudinal axis of the prosthetic valve. The position of the prosthetic valve is adjusted relative to the valve leaflets and rapid pacing is applied to the patient's heart so that the valve leaflets move inward toward the prosthetic valve or the delivery device. The tabs are further released to allow the tabs to move into their final positions.Type: GrantFiled: January 11, 2017Date of Patent: August 20, 2019Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Alexei J. Marko, Colin A. Nyuli, Krista L. Neale

Publication number: 20190060071Abstract: A sequentially deployed prosthetic cardiac valve includes a self-expanding frame having an atrial skirt, a ventricular skirt, and an annular region disposed therebetween. A first anterior tab is disposed on an anterior portion of the frame. A posterior tab is on a posterior portion of the self-expanding frame. The frame may be designed so that any portion may expand sequentially in any desired order. For example, a portion of the first anterior tab and a portion of the posterior tab may partially self-expand first. Next, the first anterior tab may fully self-expand before the posterior tab fully self-expands. The posterior tab may fully self-expand next followed by the ventricular skirt, or the ventricular skirt may self-expand next followed by full expansion of the posterior tab.Type: ApplicationFiled: August 24, 2018Publication date: February 28, 2019Applicant: Neovasc Tiara Inc.Inventors: Randy Matthew LANE, Colin A.

Patent number: 9554897Abstract: A prosthetic valve comprises a self-expanding frame which includes a self-expanding atrial skirt that forms a flanged region, a self-expanding ventricular skirt, and a first self-expanding tab coupled with the ventricular skirt. A receptacle for receiving a valve leaflet is formed by the area bounded by an outer surface of the atrial skirt, an outer surface of the ventricular skirt, and an inner surface of the first tab. The receptacle has a window for receiving the valve leaflet that is defined by a gap between an edge of the flange and a tip of the first tab. The gap is maximized when the tip of the first tab is unconstrained and a base of the first tab is at least partially constrained. The gap is minimized when the tip of the first tab and its base are unconstrained.Type: GrantFiled: February 8, 2013Date of Patent: January 31, 2017Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Colin A.

Publication number: 20140257467Abstract: A prosthetic valve for implanting in a patient's native valve has a self-expanding frame that comprises a first end, a second end opposite the first end, an anterior portion, and a posterior portion. The self-expanding frame has an expanded configuration adapted to engage tissue at a treatment site, and a collapsed configuration adapted to be delivered to the treatment site. The expandable frame also comprises a self-expanding atrial skirt near the second end, a self-expanding ventricular skirt near the first end, a self-expanding annular region disposed between first and second ends, a first self-expanding anterior tab disposed on the anterior portion, and a self-expanding foot coupled to the posterior portion and extending radially outward. The foot has an outer surface for engaging the tissue thereby facilitating anchoring of the prosthetic valve and minimizing or preventing rotation of the prosthetic valve.Type: ApplicationFiled: March 3, 2014Publication date: September 11, 2014Applicant: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Colin A.
