  • Publication number: 20180353297
    Abstract: An expandable tissue anchor is provided that includes an elongate tissue-coupling portion configured to be delivered through a cardiac tissue wall, and a flexible elongate tension member, which is coupled to a portion of the tissue-coupling portion such that a tensile force can be applied to the tissue-coupling portion after it has been expanded. A portion of the tension member is slidably disposed through a passage defined by the anchor. A sleeve encloses a portion of the tension member between the tissue-coupling portion and a distal opening of the passage. The sleeve and the passage are sized and shaped such that the size and shape of the passage prevent proximal movement of the sleeve past the passage upon application of the tensile force to the tension member, thereby limiting compression and deformation of the expanded tissue-coupling portion by the tension member. Other embodiments are also described.

  • Publication number: 20180311040
    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.

  • Publication number: 20180303609
    Abstract: A catheter-based delivery device is disclosed for delivering and deploying a prosthesis at a treatment site. The delivery device includes a sheath having a segment with a plurality of ribs, a plurality of slots and a helical spine that extends along the segment. The helical spine has a non-uniform width that provides torsional stiffness that varies along a length of the segment, wherein the torsional stiffness permits a rotational force or torque to be transferred from a proximal end to a distal end of the segment. A prosthesis may be disposed in a delivery state within the segment and may be radially aligned with a treatment site by rotating the sheath about a longitudinal axis thereof, such that torque applied to the sheath is transferred through the segment to permit the segment, and the prosthesis disposed therein, to be rotated substantially in unison with a remainder of the sheath.

  • Publication number: 20180280171
    Abstract: The present disclosure relates to delivery devices for transcatheter stented prosthesis loading, delivery and implantation. The delivery devices provide a loaded delivery state in which the stented prosthesis is loaded and compressed over the delivery device. The compression of the stented prosthesis can be adjusted with one or more elongate tension members, which extend around the stented prosthesis and proximately to an actuation and release assembly that can be provided as part of a handle assembly. The delivery device can be manipulated to adjust tension in the tension members to permit the stented prosthesis to compress, self-expand, and ultimately release from the shaft assembly. In some embodiments, the tension in one or more tension members is adjusted with one or more actuation and release assemblies.

  • Patent number: 10034680
    Abstract: A clot retrieval device (9501) for removing clot from a blood vessel comprises an inner elongate body (9503) and an outer elongate body (9504) at least partially overlying the inner elongate body (9503). The device also comprises an elongate member or shaft (9502) having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (9502). The outer elongate body (9504) and the inner elongate body (9503) are connected to the distal end of the shaft (9502) and are expandable relative to the shaft (9502) from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body (9504) is expandable relative to the inner elongate body (9503) to a radial extent which is greater than the radial extent of the inner body (9503) in the deployed configuration.

  • Publication number: 20180206989
    Abstract: Transcatheter delivery systems, delivery catheters and associated methods for percutaneous delivery of prosthetic mitral valves using a retrograde approach are disclosed herein. A heart valve delivery system configured in accordance herewith includes a delivery catheter having an elongated tubular component and an articulation assembly at a distal end thereof. The articulation assembly includes an arm portion coupled to the tubular component by an elbow or hinge portion. In a closed, delivery state, the elbow portion positions the arm portion generally parallel to the tubular component for delivery of the delivery catheter through the vasculature. In an open, deployed state, the elbow portion positions the arm portion in a non-axial direction with respect to a longitudinal axis of the tubular component for orienting and positioning a prosthetic valve device carried by the arm portion, e.g., within the native mitral valve region.

  • Publication number: 20180200058
    Abstract: A heart valve therapy system including a delivery device and a stented valve. The delivery device includes an outer sheath, an inner shaft, an optional hub assembly, and a plurality of tethers. In a delivery state, a stent frame of the prosthesis is crimped over the inner shaft and maintained in a compressed condition by the outer sheath. The tethers are connected to the stent frame. In a partial deployment state, the outer sheath is at least partially withdrawn, allowing the stent frame to self-expand. Tension in the tethers prevents the stent frame from rapidly expanding and optionally allowing recapture. Upon completion of the stent frame expansion, the tethers are withdrawn.

  • Publication number: 20180153695
    Abstract: A delivery device for implanting a prosthetic heart valve. The device includes an inner shaft assembly, an outer sheath and a connector assembly. The inner shaft assembly defines a guide wire lumen. The outer sheath is slidably received over the inner shaft assembly, and forms an exit port proximate a distal end thereof. The connector assembly establishes a guide wire passageway between the guide wire lumen and the exit port. The connector assembly is configured to permit sliding movement of the outer sheath relative to the inner shaft assembly when deploying the prosthetic heart valve. The connector assembly can include first and second tubes that are slidable relative to one another in facilitating movement of the outer sheath relative to the inner shaft assembly.

  • Publication number: 20180126127
    Abstract: Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.
