摘要: A delivery apparatus for implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart includes a handle portion and a balloon catheter assembly comprising an elongated balloon catheter shaft extending from the handle portion. The balloon catheter shaft includes a proximal end portion coupled to the handle portion and a distal end portion. The balloon catheter assembly further includes a balloon coupled to the distal end portion and configured to mount a prosthetic heart valve in a radially compressed state. A protective cover encapsulates the balloon, the cover defining a cavity shaped to accommodate the balloon.

摘要: Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

摘要: Methods and systems for attaching a radiopaque marker to a prosthetic heart valve to indicate a location of a commissure of the prosthetic heart valve are disclosed. As one embodiment, a prosthetic heart valve can include a frame including a plurality of struts forming a plurality of cells of the frame arranged between an inflow end and an outflow end of the frame, a plurality of leaflets arranged within the frame, at least one commissure comprising an attachment member arranged across a selected cell of the plurality of cells of the frame and attached to struts of the frame forming the selected cell, and commissure tabs of two adjacent leaflets coupled to the attachment member, and a radiopaque marker arranged on the attachment member of the commissure. The marker is configured to indicate a location of the commissure of the prosthetic heart valve.

摘要: A delivery apparatus for implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart includes a handle portion and an elongated shaft extending from and movable relative to the handle portion. The shaft includes a proximal end portion coupled to the handle portion and a distal end portion configured to mount a prosthetic heart valve in a radially compressed state. The handle portion includes a control member movable longitudinally with respect to the handle portion, the control member engaging a gear assembly operable to convert longitudinal motion of the control member to rotational motion of the gear assembly. The gear assembly engages the elongated shaft such that rotational motion of the gear assembly causes corresponding longitudinal motion of the elongated shaft relative to the handle portion.

摘要: An introducer sheath has a radially unexpanded and a radially expanded configuration, where the sheath locally expands from the unexpanded configuration to the expanded configuration when a device is advanced through a lumen thereof, and locally contracts back to the unexpanded configuration after the device advances past that location. Embodiments of the introducer sheath include an outer tubular layer comprising a longitudinal cut therethrough, and an inner tubular layer comprising at least one pleat extending through the longitudinal cut to an outside surface of the outer tubular layer. Embodiments of the inner tubular layer are adhered to an inner surface of the outer tubular layer, with the pleat not adhered to an outer surface of the outer tubular layer.

摘要: Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. In some examples, a method can include advancing a distal end portion of an assembly toward a native heart valve, the assembly comprising a delivery apparatus and a prosthetic heart valve, and including one or more radiopaque markers, where one radiopaque marker is suspended within a cell of a frame of the prosthetic heart valve and aligned with a commissure of the prosthetic heart valve. The method further includes receiving a fluoroscopic image in a selected imaging view of the prosthetic heart valve on the delivery apparatus, determining, based on the fluoroscopic image and the one or more radiopaque markers, whether the prosthetic heart valve is in a desired rotational orientation, and rotating the assembly until the prosthetic heart valve is in the desired rotational orientation.
