  • Patent number: 10857015
    Abstract: A sheath of a delivery system is retracted by winding in cords coupled to the sheath. More particularly, a helical reel is rotated to wind the cords into a helical cord groove and retract the sheath. Rotation of the helical reel simultaneously causes a cord feed ring to slide ensuring that that the cords are correctly fed into the helical cord groove through cord feedthrough apertures of the cord feed ring. Initially, due to a minimal diameter of the helical cord groove, the cords are retracted slowly and with a high amount of torque, e.g., a high mechanical advantage. After retraction of the sheath has begun, the speed of retraction of the sheath is increased with reduced torque as the cords are wound around the increasing diameter of the helical cord groove.

  • Patent number: 10813755
    Abstract: The disclosure relates to transcatheter stented prosthesis delivery devices including transition elements that route, constrain, support and reduce damage to tension member wear as tension in the tension members is varied to adjust the compression of a stented prosthesis loaded onto the delivery device. Various disclosed tension elements include inserts, edge treatments and guides proximate a distal portion of the delivery device upon which the stented prosthesis is loaded. In some embodiments, the transition feature is positioned proximate a location where at least one tension member transitions from a first orientation that is not parallel to the distal portion to a second orientation that is generally parallel to the distal portion. Further embodiments disclose configurations and methods of selectively locking and unlocking a longitudinal and/or rotational position of the stent frame with respect to the distal portion of the delivery device.

  • Patent number: 10813778
    Abstract: The present disclosure relates to stents and methods of delivering and deploying the same. The stents include fasteners about their periphery and when the stent is radially compressed, the fasteners come into alignment such that a device may be placed through openings in the fasteners to hold the stent in the radially compressed configuration. When the device is removed from the openings, the stent may expand.

  • Patent number: 10806613
    Abstract: A stent and a securely-installed artificial valve replacement device having the same, the stent being of a cylindrical structure; the top of the stent is provided with a fixed ear (60); the fixed ear (60) has a neck portion (601) connected to the top of the stent, and a head portion (602) engaged with the fixed head of the stent; the head portion (602) has a bending structure for improving the overall radial thickness; and the artificial valve replacement device is comprised of a stent and a prosthetic valve fixed on the stent. The stent with a bending structure overcomes the problem of easily disengaging from the fixed head of the stent, while not affecting the release of the stent.

  • Patent number: 10786351
    Abstract: Apparatus and methods are described herein for use in the transvascular delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when the valve is in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The distal end portion of the delivery sheath is inserted into a left atrium of a heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. In some embodiments, actuation wires are used to assist in the reversion of the outer frame. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

  • Patent number: 10758386
    Abstract: Some implementations of an endovascular device include a stent graft with an expandable tubular metallic frame and a covering material disposed on at least a portion of the metallic frame. The stent graft defines a lumen therethrough. In a particular embodiment, a first balloon is disposed around an outer periphery of the stent graft, a second balloon is disposed around the outer periphery of the stent graft and spaced apart from the first balloon, and a third balloon is disposed within the stent graft lumen between the first balloon and the second balloon. The third balloon can be inflated to fully or partially occlude the lumen. The first and second balloons can be individually inflated to fully or partially shunt blood flow from a blood vessel through the stent graft. In some embodiments, sensors and an automated control unit are included to automate the operations of the endovascular device.
