  • Patent number: 11191631
    Abstract: A removable dual endovascular filter that may be introduced into arteries of the heart during surgery to allow sufficient blood flow to a cerebral vascular system while minimizing or preventing embolic material from traveling throughout a body circulatory system. The removable dual endovascular filter reduces the risk of stroke while minimizing obstruction of the patient's aorta.

  • Publication number: 20210369284
    Abstract: Disclosed are embodiments of a method for occluding a left atrial appendage (LAA) and other cavities or openings within a body. Some embodiments of the method can include an implant configured to be deployed within the LAA or other cavity, configured to be expanded or moved against a wall portion of the LAA or other cavity, and configured to twist at least a portion of the LAA or other cavity when the implant is rotated. Thereafter, one or more securing elements, staples, sutures, or other fasteners can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the LAA or other cavity. In some embodiments, the opening of the LAA or other cavity can be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.

  • Patent number: 11141258
    Abstract: Single filter and multi-filter endolumenal methods and systems for filtering fluids within the body. In some embodiments a blood filtering system captures and removes particulates dislodged or generated during a surgical procedure and circulating in a patient's vasculature. In some embodiments a filter system protects the cerebral vasculature during a cardiac valve repair or replacement procedure.

  • Publication number: 20210298728
    Abstract: Disclosed are embodiments of a device for closing or occluding a cavity or opening within a body. Some embodiments of the device can include an implant configured to be deployed within the cavity, configured to be expanded or moved against a wall portion of the cavity, and configured to twist at least a portion of the cavity when the implant is rotated. Thereafter, a securing element, staple, suture, or other fastener can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the cavity. The implant can remain in the cavity or be removed.

  • Publication number: 20210186699
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium, through the mitral valve, and into the left ventricle. A ventricular anchor is deployed from the catheter and into a wall of the left ventricle, leaving a ventricular suture attached to the ventricular anchor and extending proximally through the catheter. A leaflet anchor is deployed to secure a mitral valve leaflet to a leaflet suture, with the leaflet suture extending proximally through the catheter. The leaflet suture is secured to the ventricular suture to limit a range of travel of the leaflet in the direction of the left atrium. Also disclosed is an assembled in situ mitral valve leaflet restraint, having a neo papillary muscle and a neo chordae tendinea.

  • Publication number: 20200015967
    Abstract: An implantable prosthetic valve for a human heart is disclosed. The prosthetic valve has an inflatable tubular annular support structure and at least one moveable occluder that controls the flow of blood through the support structure. The support structure has a flow control valve configured for coupling to an inflation lumen for inflating the support structure with an inflation media. The flow control valve seals after decoupling from the inflation lumen and prevents the inflation media from escaping.

  • Publication number: 20200000582
    Abstract: An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.

  • Publication number: 20190321608
    Abstract: A method of treating a patient with a calcified aortic valve includes introducing a guide wire into a blood vessel. The guide wire is advanced through the aorta to the aortic valve and then through the aortic valve. A balloon dilatation catheter is introduced into the blood vessel over the guide wire. The balloon dilatation catheter includes an elongate body, a distal portion, a guide wire lumen, an inflation lumen, and a dilatation balloon. The balloon dilatation catheter further includes at least one deflection wire lumen, and at least one deflection wire residing in the at least one deflection wire lumen and having a distal end attached to the distal portion. The balloon dilatation catheter is advanced over the guide wire through the aorta, through the aortic valve, and the dilatation balloon is inflated.
