  • Publication number: 20260130763
    Abstract: A catheter assembly includes a handle assembly, a steerable catheter, and an actuation element. The handle assembly includes a handle housing, a guide member, a follower, and a driver. The driver engages the follower to cause the follower to move relative to the guide member. The actuation element is connected to the follower and the steerable catheter. Movement of the follower relative to the guide member causes the actuation element to engage the steerable catheter to move the steerable catheter between the flexed configuration and the unflexed configuration.

  • Publication number: 20260114993
    Abstract: Disclosed are embodiments of replacement heart valves. Embodiments may include a collapsible and expandable frame comprising rows of cells. The frame may include a plurality of axial connection portions extending between top ends and bottom ends of the cells, wherein each axial connecting portion is shaped to bend for accommodating temporary changes in cell height during non-uniform compression of the replacement heart valve. Frames having these features are advantageous when advancing a replacement heart valve through a funnel-shaped compression tool. The axial connection portions are sufficiently flexible to accommodate changes in frame shapes during compression while also being sufficiently resilient for enhancing the structural integrity of the frame in the fully deployed state. The replacement heart valves are preferably dual-frame heart valves, wherein the axial connection portions form a portion of an inner frame and wherein an outer frame is provided for engaging tissue and forming a seal.

  • Publication number: 20250312150
    Abstract: A prosthetic heart valve includes a self-expanding frame and a plurality of prosthetic valve leaflets positioned within an interior of the frame. Ventricular anchors extend from a downstream portion of the frame and are shaped for capturing native leaflets. Barbs are preferably provided along an outer surface of the frame for enhanced fixation. The self-expanding frame may include an inner frame for supporting the prosthetic valve leaflets and an outer frame for sealing against the tissue of the native heart valve. The inner and outer frames may be attached via a flexible intermediate component for allowing the inner frame to move relative to the outer frame. The outer frame may be more conformable than the inner frame and the outer frame may include axial recesses for receiving the ventricular anchors and thereby reducing profile after implantation. The prosthetic heart valve is preferably sized to replace a native tricuspid valve.

  • Patent number: 12396850
    Abstract: Catheterization methods and apparatuses allow sensing of pressures inside the heart and for removing air from catheters. A delivery system can use the same components that are used to deliver a valve repair or replacement device to measure the pressure in the atrium or other heart chamber. A pressure sensor can be included in one of the catheters of the delivery system or pressure can be sensed through the same port that is used to flush a catheter. The delivery system can be inserted into the heart, delivering the valve repair or replacement device to the native valve, such as the mitral valve, the tricuspid valve, the aortic valve, or the pulmonary valve.

  • Publication number: 20250152359
    Abstract: In a method of treating an atrioventricular valve, a sealing element is deployed in a native atrioventricular valve of a heart at a position between native atrioventricular valve leaflets to contact the native atrioventricular valve leaflets. The sealing element is controlled by user input to both radially expand and radially reduce the sealing element while at the position between the native atrioventricular valve leaflets. At least one of the native atrioventricular leaflets is secured between an inner anchor member and an outer anchor member to support the sealing element at a desired position between the native atrioventricular valve leaflets.
