A method for deploying a stent device having a main body, a proximal coupling, and a distal coupling. The method includes extending a first guidewire in an aorta, extending a second guidewire in a brachiocephalic artery, and extending a third guidewire in an aortic branch vessel. The method further includes tracking the stent device along the first, second, and third guidewires. During the tracking step, the first guidewire extends through the main body, the second guidewire extends through the proximal coupling, and the third guidewire extends through the distal coupling. The method also includes deploying the main body within the aorta with the proximal coupling aligning with the brachiocephalic artery and the distal coupling aligning with the aortic branch vessel.

The present disclosure relates generally to stents, systems, and methods for gastrointestinal treatment. In some embodiments, a stent may include a tubular scaffold having a first end opposite a second end, wherein a lumen extends between the first and second ends. The tubular scaffold may include a flared section and a medial section extending from the flared section, wherein a first diameter of the flared section is greater than a second diameter of the medial section. The stent may further include a liner extending partially along a surface of the tubular scaffold, wherein the liner is spaced from an anchoring region of the flared section to promote tissue ingrowth with the flared section.

A medical device includes a polymer stent (or scaffold) crimped to a catheter balloon. The stent, after being expanded from a crimped state by the balloon, provides a crush recovery of about 90% of its expanded diameter after being pinched or crushed by an amount equal to about 50% of the expanded diameter. The stent has a pattern including a W-shaped or W-V shaped closed cell and links connecting the closed cells.

An annuloplasty device is disclosed comprising first and second support rings having a coiled configuration, and respective first and second retention units, the first support ring transitions to the second support ring over a transition section, the transition section is adapted to be arranged at a commissure of the heart valve leaflets, a first posterior bow of the first support ring and a second posterior bow of the second support ring extend in respective first and second coil planes being essentially perpendicular to the central axis, the transition section bends at least partly along the central axis so that the first coil plane is separated a distance from the second coil plane along the central axis at the transition section.

An implantable device comprising a main endoprosthesis configured for implantation in a vessel, the main endoprosthesis including at least one side portal, a first side-branch endoprosthesis configured to be deployed within the main endoprosthesis and direct flow through a first side-branch vessel via the at least one side portal, a second side-branch endoprosthesis configured to be deployed within the main endoprosthesis and direct flow through a second branch vessel via the at least one side portal, and wherein when not containing a side-branch endoprosthesis the at least one side portal comprises a side channel without fluid separation.

A luminal endoprosthesis (1) at least partially delimits a prosthesis lumen (2), for implantation in an anatomical structure (3) that at least partially defines at least one cavity (4) and includes a pathological portion (13). The luminal endoprosthesis (1) includes two or more layers (5, 6, 7), at least one layer (5, 6, 7) having at least one threadlike element (8) forming an armor (9). The luminal endoprosthesis (1) includes an anchoring portion (10), for anchoring to an anatomical portion (11) of the walls of the cavity (4) of the anatomical structure (3). A working portion (12) faces the pathological portion (13) of the anatomical structure (3). The two or more layers (5, 6, 7) are separated from each other at least in the working portion (12) of the luminal endoprosthesis (1), avoiding connecting elements between one layer (5, 6, 7) and at least one adjacent layer.

Certain examples of the disclosure concern a docking device for securing a prosthetic valve at a native valve. The docking device includes a coil having a plurality of helical turns when deployed at the native valve, an expandable member extending radially outwardly from the coil and being movable between a radially-compressed/axially-elongated state and a radially-expanded/axially-foreshortened state, and a cover member surrounding an outer surface of the expandable member. A distal end portion of the cover member and a distal end portion of the expandable member are fixedly coupled to the coil via a distal suture including a plurality of knots and a plurality of wraps. A proximal end portion of the expandable member is fixedly coupled to a proximal end portion of the cover member. The proximal end portion of the expandable member and the proximal end portion of the cover member are axially movable relative to the coil.

The techniques of this disclosure generally relate to an assembly including a docking graft. The docking graft includes a main graft defining a main lumen, a first internal lumen within the main lumen, a second internal lumen within the main lumen, and a main docking lumen within the main lumen. The first and second internal lumens are configured to receive first and second bridging stent graft therein. The main docking lumen is configured to receive a tube graft therein. The first internal lumen, the second internal lumen, and the main docking lumen being parallel to one another and extending an entire length of the docking graft when the docking graft is in a relaxed configuration. The docking graft forms the foundation, or anchor device, for attachment of the first bridging stent graft, the second bridging stent graft, and the tube graft within the aorta.

An implantable prosthetic device such as might be used to treat poor function of a diseased heart valve in a medical patient includes a body portion and an anchor portion including a plurality of paddles. Clasps attached to the paddles include fixed arms and moveable arms operable to secure the device to the patient's native valve leaflets.

The present disclosure describes devices, systems, and methods for loading, delivering, positioning, and deploying an artificial heart valve device at the mitral annulus. A delivery system includes a delivery member coupled to a handle assembly and extending distally from the handle assembly. The valve device is attached at the distal end of the delivery member, and is constrained within a valve cover of an outer sheath. A delivery catheter is configured to advance the valve relative to the outer sheath, and a suture catheter includes sutures/tethers which maintain proximal tension on the valve prior to deployment.
