摘要： Balloon covers for a delivery apparatus for a prosthetic valve are disclosed. As one embodiment, a balloon cover includes first and second shell members that are configured to matingly engage with each other, each of the first and second shell members including a first portion and a second portion, the second portion having a larger width than the first portion. The first portions of the first and second shell members define a first cavity configured to receive a distal end portion of the delivery apparatus and at least a portion of an inflatable balloon mounted on the distal end portion of the delivery apparatus. The second portions of the first and second shell members define a second cavity configured to receive a positioning device mounted on the distal end portion of the delivery apparatus, proximal to a valve mounting portion of the distal end portion of the delivery apparatus.

摘要： Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. As one embodiment, a delivery apparatus can include a first shaft that is configured to rotate around a central longitudinal axis of the delivery apparatus; a second shaft extending through the first shaft and having a distal end portion extending distally beyond a distal end portion of the first shaft; an inflatable balloon coupled to the distal end portion of the first shaft; and a shoulder arranged within the balloon and a radiopaque marker mounted on or embedded within the shoulder at a location spaced radially outward from an outer surface of the distal end portion of the second shaft. The marker can be reflection asymmetric along an axis that is parallel to the central longitudinal axis.

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.
