  • Publication number: 20190328527
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Publication number: 20190328529
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. A helical ventricular anchor subassembly is advanceable through the catheter, having a ventricular suture extending proximally through the catheter. A leaflet anchor subassembly is advanceable through the catheter, having a leaflet suture extending proximally through the catheter. From an atrium side, the leaflet anchor subassembly can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to the leaflet suture. The ventricular anchor subassembly secures the ventricular anchor to a ventricular wall. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Publication number: 20190328502
    Abstract: Disclosed are methods and devices for isolating all three of the left subclavian, left common carotid and brachiocephalic arteries from embolic debris that might flow through the aortic arch, via a single access point. A system may include an elongate flexible tubular sheath, having a proximal end and a distal end, and an inner member extending through the sheath and moveable relative to the sheath. A left subclavian element may be supported by the inner member. A filter membrane may be configured to isolate the aorta from the brachiocephalic, left common carotid and left subclavian arteries when the left subclavian element is expanded within the left subclavian artery and the sheath is retracted to expose the membrane. The left subclavian element may include a self expandable frame, which may carry a left subclavian filter.

  • Publication number: 20190328528
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium to attach a leaflet anchor having a leaflet suture to a mitral valve leaflet. A ventricular anchor has a hub with a helical anchor and a core wire extending through the helical anchor. A radiopaque marker may be axially movably carried on the core wire, and a spring biases the marker in a distal direction. The marker is advanced proximally on the tissue surface relative to the helical anchor as the helical anchor is advanced distally into tissue to secure a ventricular suture to the ventricular wall. A leaflet suture and the ventricular suture may be tensioned and connected by a suture lock to form an artificial chordae.

  • Publication number: 20190328530
    Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet anchor having a leaflet suture is secured to the mitral valve leaflet. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae. The suture lock has a body with a suture path extending therethrough. A wall in the housing is movable to reduce the cross section of the suture path. A drive mechanism advances the movable wall to clamp sutures extending through the suture path, in response to rotation of a coupling on the housing.

  • Patent number: 10449028
    Abstract: Vascular filters and deflectors and methods for filtering bodily fluids. A blood filtering assembly can capture embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature. A blood deflecting assembly can deflect embolic material dislodged or generated during an endovascular procedure to inhibit or prevent the material from entering the cerebral vasculature.
