  • Patent number: 12285330
    Abstract: A prosthesis can comprise an expandable frame, a plurality of distal anchors and a plurality of proximal anchors. The anchors can extend outwardly from the frame. The frame can be configured to radially expand and contract for deployment within a body cavity. The frame and anchors can have one of many different shapes and configurations. For example, when the frame is in an expanded configuration, the frame can have a larger cross-sectional dimension in a middle portion of the frame and a smaller cross-sectional dimension in a proximal portion and a distal portion of the frame, wherein the middle portion is between the proximal and distal portions. As another example, the anchors can have looped ends, the entire anchor may loop out from the frame.

  • Patent number: 12150853
    Abstract: A prosthetic heart valve (e.g., a prosthetic aortic valve) is designed to be somewhat circumferentially collapsible and then re-expandable. The collapsed condition may be used for less invasive delivery of the valve into a patient. When the valve reaches the implant site in the patient, it re-expands to normal operating size, and also to engage surrounding tissue of the patient. The valve includes a stent portion and a ring portion that is substantially concentric with the stent portion but downstream from the stent portion in the direction of blood flow through the implanted valve. When the valve is implanted, the stent portion engages the patient's tissue at or near the native valve annulus, while the ring portion engages tissue downstream from the native valve site (e.g., the aorta).

  • Patent number: 12144731
    Abstract: A side-deliverable prosthetic heart valve includes an outer frame and a flow control component. The outer frame defines a central channel that extends along a central axis. The flow control component is disposed within the central channel and coupled to the outer frame. The flow control component has a set of leaflets mounted within an inner frame. The prosthetic valve is configured to be folded along a longitudinal axis and compressed along the central axis to place the prosthetic valve in a compressed configuration for delivery via a delivery catheter. The longitudinal axis is substantially parallel to a lengthwise axis of the delivery catheter when disposed therein. The prosthetic valve transitions to an expanded configuration when released from the delivery catheter. The flow control component elastically deforms from a substantially cylindrical configuration to a substantially flattened configuration when the prosthetic valve is placed in the compressed configuration.

  • Patent number: 12138161
    Abstract: A prosthetic heart valve is designed to be circumferentially collapsible for less invasive delivery into the patient. At the implant site the valve re-expands to a larger circumferential size, i.e., the size that it has for operation as a replacement for one of the patient's native heart valves. The valve includes structures that, at the implant site, extend radially outwardly to engage tissue structures above and below the native heart valve annulus. These radially outwardly extending structures clamp the native tissue between them and thereby help to anchor the prosthetic valve at the desired location in the patient.

  • Patent number: 12127940
    Abstract: A patch for interposing between an implantable device and a treatment site, such as to inhibit migration (e.g., lateral shifting) of the implantable device with respect to the treatment site without interfering with contact of the implantable device with the treatment site, and/or to reduce (and preferably inhibit or prevent) damage to tissue at the treatment site and/or movement of the anchor element (used to anchor the implantable device) with respect to the treatment site. The patch may extend continuously around the perimeter of the device, or discontinuously as more than one patch. The patch may be delivered on the implantable device to the treatment site, or separately delivered and deployed before the implantable device is delivered and deployed, the implantable device being implanted over the patch and the treatment site.

  • Patent number: 12121436
    Abstract: A prosthetic heart valve is disclosed that is deformable between collapsed, radially uncompressed, and target conditions. The prosthetic heart valve includes an inner frame, at least one leaflet, and a braided wire mesh arranged outside and coupled to the inner frame by a coupling portion. The braided wire mesh includes a body portion between the coupling portion and a flared portion. In the radially uncompressed condition, the prosthetic heart valve forms a cavity surrounded by the braided wire mesh and the inner frame. In the target condition, only a part of the length of the body portion is radially compressed along an axis extending from an upstream side to a downstream side. In the collapsed condition, the inner frame and braided wire mesh are radially collapsed over their entire length. In the radially uncompressed condition, the body portion is tubular and the braided wire mesh has a rotationally symmetric circumference.

  • Patent number: 12115065
    Abstract: A prosthetic heart valve assembly includes a self-expandable stent having a flared upper portion, a lower portion, and an intermediate portion extending from the upper portion to the lower portion. The stent includes upwardly bent hooks extending from an outer surface of the stent, which are adapted to engage native leaflet tissue. The stent further includes an elongate anchoring member extending from the lower portion of the stent, which is adapted to be secured to a ventricle wall via a prong portion. When deployed within the native heart valve, the flared upper portion contacts a supra-annular surface of the native heart valve for preventing downward migration of the prosthetic heart valve assembly toward the ventricle and the upwardly bent hooks and the elongate anchoring member prevent upward migration of the prosthetic heart valve assembly toward an atrium.
