  • Patent number: 10842620
    Abstract: A method of implanting a prosthetic heart valve includes advancing a prosthetic heart valve to an implantation location within a patient's body, positioning the prosthetic heart valve within a native heart valve annulus, expanding a frame of the prosthetic heart valve from a first contracted configuration to a first expanded configuration, and then contracting the frame to a second contracted configuration. The prosthetic heart valve may be repositioned and then re-expanded from the second contracted configuration to a second expanded configuration. The prosthetic heart valve is preferably released from the delivery apparatus while in the second expanded configuration. Releasing the prosthetic heart valve from the delivery apparatus may result in radial expansion of a flange portion of the prosthetic heart valve.

  • Patent number: 10828184
    Abstract: A vascular stent may be used to maintain or enhance patency of a blood vessel. By using multiple, separate stent elements that are balloon expandable, the multi-element stent may be stronger than a traditional self-expanding stent but may also be more flexible, due to its multiple-element configuration, than a traditional balloon-expandable stent. The stent elements are formed from a bioresorbable polymer material. The radial rigidity of the stent is configured to decrease after implantation in a vessel as the polymer is absorbed. The thickness of the stent, cell shape, polymer material, and/or treatment of the polymer material may be configured to provide a high initial radial rigidity to the vessel upon implantation and a decrease in the radial rigidity of the vessel over time.

  • Patent number: 10779969
    Abstract: A plaque tack can be used for holding plaque against blood vessel walls such as in treating atherosclerotic occlusive disease. The plaque tack can be formed as a thin, annular band for holding loose plaque under a spring or other expansion force against a blood vessel wall. Focal elevating elements and/or other features, such as anchors, can be used to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the endoluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

  • Patent number: 10624621
    Abstract: A device (10) for treating heart failure in a patient. The device (10) comprising a body (12), at least one passage (18) through the body (12), at least one one way valve (20) in the passage (18) and a mounting means (14) adapted for mounting the body (12) in an opening provided in the patient's atrial septum. In use, the device (10) is oriented such that, when the patient's left atrial pressure exceeds the patient's right atrial pressure by a predetermined amount, the one way valve(s) (20) opens to allow blood flow through the passage(s) from the left atrium to the right atrium to thereby reduce the left atrial pressure.

  • Patent number: 10617540
    Abstract: Stents formed from dissimilar materials configured to control tissue growth. A stent may be formed from a composite wire helically wound into a stent having a tubular configuration. The composite wire includes a first wire and a second wire coupled together, the first and second wires being formed from dissimilar metals such that a potential difference is formed when the dissimilar metals are exposed to bodily fluids. The potential difference is configured to inhibit cell proliferation and thereby control tissue growth around the stent after implantation. A stent may be formed from a hollow composite wire including an inner member that includes first and second longitudinal strips formed from dissimilar metals. A stent may be formed from a composite wire having a plurality of windows along a length of the composite wire. An insert formed from a dissimilar metal is disposed within each window of the plurality of windows.

  • Patent number: 10617541
    Abstract: A strand made of a platinum alloy material is prevented from protruding from both ends of a stent when some strands of the stent are disposed using the strand made of the platinum alloy material. In a stent (10) which is formed by helicoidally braiding a plurality of strands, some strands among the plurality of strands are disposed using a strand made of a platinum alloy material, and a length of the strand made of the platinum alloy material is made shorter than lengths of other strands by a length of the strand made of the platinum alloy material which is estimated to protrude from the stent.

  • Patent number: 10617514
    Abstract: An endoluminal device can comprise a flexible tubular wall and a frame member. The frame member can be comprised of a shape-memory material having sides with protrusions which are partially or substantially flattened when formed together with the flexible tubular wall to thereby create a bias in the side wall of the endoluminal device that resists deformation from a desired device profile during crush loading and is thereby resistant to invaginations when deployed.

  • Patent number: 10610231
    Abstract: Methods for treatment of a cerebral aneurysm within a cerebral vasculature of a patient are described. A microcatheter and a device for treatment of the aneurysm are provided. The device is a self-expanding resilient permeable shell having a plurality of elongate resilient filaments with a woven structure. The plurality of filaments includes small and large filaments. The filaments are bundled and secured to each other at a proximal end. A ratio of the total cross-sectional area of small filaments to the total cross-sectional area of large filaments may be between 0.56 and 1.89. The distal end of the microcatheter is advanced to a region of interest within a cerebral artery. The device is advanced through the lumen and out of the distal end of the microcatheter such that the permeable shell deploys and expands within the cerebral aneurysm. The microcatheter is then withdrawn from the cerebral artery.

  • Patent number: 10595992
    Abstract: A device for providing cardiac treatment at the left atrium of a patient's heart. The device includes a retention body and a prosthetic valve. The retention body has a shape that can be manipulated between a collapsed state and a normal or expanded state. First and second openings are defined at one side of the retention body, and a lower opening is defined at an opposite side. The prosthetic valve is carried by the retention body at the lower opening. The retention body is configured to engage a substantial portion of an interior surface of the left atrium, securing the prosthetic valve at a desired location relative to a native mitral valve (e.g., within the mitral valve or slightly spaced from the mitral valve). The first and second openings are sized and shaped so as to permit blood flow from the pulmonary veins into the interior region.

  • Patent number: 10583000
    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.
