Abstract: An intravascular stent is provided to be implanted in coronary arteries and other body lumens. The transverse cross-section of at least some of the stent struts have a ratio of polar and bending moments of inertia, which results in optimal resistance to stent twisting. This resistance to twisting ratio for the stent struts minimizes out of plane twisting of the struts or projecting edges of the struts when the stent is expanded from a compressed diameter to an expanded diameter in a coronary artery.

Abstract: A method for treating a patient diagnosed with a cardio-renal disease or disorder, the method comprising selecting a span of a renal artery having a first internal diameter, an artery wall; selecting a self-expanding stent having a cylindrical outer surface, the stent being configured to have a first external diameter in an unexpanded condition and being capable of expanding to have a second external diameter; implanting the stent in the span of the renal artery, and applying pressure to the at least one renal nerve with the stent, thereby at least partially modulating a function of the at least one renal nerve; then, reducing an elastic modulus of the stent when the stent has the second external diameter.

Abstract: A catheter apparatus for treatment of a human patient is described, the catheter apparatus having a central axis and comprising a shaping structure moveable between a delivery state having a first helical shape, and a deployed state having a second helical shape. The shaping structure is configured to have a reverse taper with a structural diameter that varies over the length of the shaping structure such that the structural diameter of the shaping structure at the proximal end is smaller than the structural diameter of the shaping structure at the distal end.

Abstract: A stent has one or more redundant crests for a ring. The redundant crest is located at a Y-crown for a peak-to-valley type stent pattern in one example. The stent may also have frangible bridges for connecting links. The stent's radial stiffness decreases when a redundant crest fractures and its axial and bending stiffness decreases when a frangible bridge breaks.

Abstract: The invention provides medical devices, systems and methods for tissue approximation and repair and in particular to reduce mitral regurgitation by means of improved coaptation. The devices, systems and methods of the invention will find use in a variety of therapeutic procedures, including endovascular, minimally-invasive, and open surgical procedures, and can be used in various anatomical regions, including the cardiovascular system, heart, other organs, vessels, and tissues. The invention is particularly useful in those procedures requiring minimally-invasive or endovascular access to remote tissue locations, where the instruments utilized must negotiate long, narrow, and tortuous pathways to the treatment site.

Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.

Abstract: A thin-walled scaffold includes a radiopaque marker connected to a link. In a first example, the marker is retained on the strut by a head at one or both ends by swaging. In a second example of a thin-walled scaffold the link is modified to avoid interference during crimping. In a third example a distal end of the thin-walled scaffold is modified to improve deliverability of the thin-walled scaffold. These features are combined in a fourth example.
