Patent number: 12201524Abstract: Methods for the rapid retraction of trans-catheter heart valve delivery systems are provided. A rapid retraction trans-catheter heart valve delivery system comprises a catheter based delivery system. The delivery system has internal mechanisms that allow for the controlled deployment of a heart valve prosthesis, as well as mechanisms that allow for quickly closing the catheter once the heart valve prosthesis has been implanted. This rapid retraction ability allows for reduced procedural durations and thus reduced risk to the patient.Type: GrantFiled: September 2, 2022Date of Patent: January 21, 2025Assignee: Neovasc Tiara Inc.Inventors: Ian Fraser Kerr, Karen Tsoek-Ji Wong, Colin Alexander Nyuli, Randy Matthew Lane

Patent number: 12193932Abstract: 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: May 9, 2022Date of Patent: January 14, 2025Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Karen Tsoek-Ji Wong, Ian Fraser Kerr, Mark Segal

Patent number: 12138159Abstract: 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: October 13, 2022Date of Patent: November 12, 2024Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Colin A. Nyuli, Alexei J. Marko

Patent number: 12109111Abstract: A delivery system includes a delivery catheter with a capsule configured to carry a prosthesis and a steering catheter for steering the delivery catheter. The delivery catheter can be advanced through a patient's vasculature to a target treatment area. The capsule can be opened and the prosthesis can be deployed into the target treatment area. Additionally, a method for delivering a prosthesis to a target treatment area includes advancing a delivery catheter through a patient's vasculature to the target treatment area, steering the delivery catheter toward the target treatment area, opening a capsule on the delivery catheter, and deploying the prosthesis into the target treatment area.Type: GrantFiled: March 9, 2020Date of Patent: October 8, 2024Assignee: Neovasc Tiara Inc.Inventors: Colin A. Nyuli, Randy Matthew Lane, Karen Tsoek-Ji Wong

Publication number: 20240293226Abstract: A system comprised of a prosthetic heart valve device (535, 555, 900, 1108, 1230, 1260, 1400, 1535), and a delivery system (1100, 1105, 1110, 1300, 1500). The prosthetic heart valve device (535, 555, 900, 1108, 1230, 1260, 1400, 1535) comprises a differentially deformable anchoring structure concentrically aligned with, radially adjacent to, and in direct connection with a valve frame (700). The atrial region (805, 1005, 1410, 1805, 1850) of the differentially deformable anchoring structure (800, 1229, 1259) comprises a plurality of alignment structures intended to aid in rotational orientation. This atrial region (805, 1005, 1410, 1805, 1850) is in direct connection with the valve frame through inflow region connection elements. The annular region of the differentially deformable anchoring structure comprises anchoring elements and an architecture having a radial stiffness suitable for deformation and conformation to the native anatomy; this region is void of connection to the valve frame.Type: ApplicationFiled: June 2, 2023Publication date: September 5, 2024Inventors: Randy Matthew Lane, Colin Alexander Nyuli, Zhibin Fu

Patent number: 12053369Abstract: 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: GrantFiled: July 8, 2022Date of Patent: August 6, 2024Assignee: Neovasc Tiara Inc.Inventors: Randy Matthew Lane, Colin A. Nyuli, Alexei J. Marko, Krista L. Neale

Publication number: 20230310149Abstract: A system comprised of a prosthetic heart valve device, and a delivery system. The prosthetic heart valve device comprises a differentially deformable anchoring structure concentrically aligned with, radially adjacent to, and in direct connection with a valve frame. The delivery system is comprised of a proximal control assembly connected to a first elongate, bendable catheter comprising a primary inner lumen, one or more secondary lumens adjacent to the primary lumen, one or more tethers releasably connected to the atrial portion of the prosthetic heart valve device, and a second elongate, bendable catheter with connection elements that are releasably connected to the ventricular portion of the prosthetic heart valve device.Type: ApplicationFiled: December 4, 2020Publication date: October 5, 2023Inventors: Randy Matthew LANE, Colin Alexander NYULI, Zhibin FU

Publication number: 20230149163Abstract: 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: July 21, 2022Publication date: May 18, 2023Inventors: Randy Matthew Lane, Colin A.
