Abstract: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.

Abstract: Stent device has a stent cover bonding to the stent wires forming the stent body at a plurality of bonding portions that are remote from the cross over points of the stent wire. By allocating the bonding portions to the stent wires in between the cross over portions, the axial flexibility of the stent device is maintained. The stent cover bonded by the disclosed bonding portions contributes to preventing lumen tissues to penetrate into the stent body and clogging the stent while placement of the bonding portions bonding the stent cover to the stent device provides variations of positive effects to the cover stent device and to the patient in which the stent device is placed.

Abstract: Endovascular prostheses used to treat diseased blood vessels, such as arteries, are disclosed. In some embodiments, an endovascular prosthesis is configured to be implanted within a diseased blood vessel adjacent a diseased section. The endovascular prosthesis may include a fenestration tube through which a guidewire extends in a sealed configuration. The fenestration tube can be selectively openable and configured to sealingly receive an expandable endovascular prosthesis that extends into a side branch vessel of the diseased blood vessel.

Abstract: The present invention relates generally to an apparatus for placing a stent at a desired location within the human body. In particular, but not exclusively, the apparatus is configured to place a stent within the ureter or other passage or space within the human body. The invention may be embodied as an apparatus for inserting a stent into a bodily structure of a subject, the apparatus comprising: a stent guide wire, a first moving means configured to move the stent guide wire toward a bodily structure of a subject, a stent pusher disposed about the stent guide wire, and a second moving means configured to move the stent pusher independently of and relative to the stent guide wire.

Abstract: 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 example, a prosthetic heart valve can include a frame, a plurality of leaflets arranged within the frame, and at least one commissure comprising an attachment member comprising a central portion and a flap extending outward from the central portion, the flap folded over a radially outward facing side of the central portion, and the attachment member arranged across a selected cell of the frame. The commissure further comprises commissure tabs of two adjacent leaflets coupled to a radially inward facing side of the central portion, and a radiopaque marker arranged on the flap of the attachment member, between the flap and the radially outward facing side of the central portion.

Abstract: A delivery device for percutaneously delivering a stented prosthetic heart includes a sheath, a handle, and adjustment device including a fine adjustment mechanism, and an outer stability shaft. The sheath defines a lumen and is configured to compressively constrain the stented prosthetic heart valve. The handle is coupled to the proximal portion of the sheath and includes an actuator mechanism coupled to a proximal portion of the sheath that is configured to selectively move the sheath relative to the housing to release the stented prosthetic heat valve. The adjustment device is coupled to the handle and includes an adjustment lumen through which the sheath and the handle slidably extend. The outer stability shaft is coupled to the adjustment device. The fine adjustment mechanism is configured to selectively move the handle and the sheath relative to the adjustment device and the outer stability shaft.
