摘要： 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.

摘要： A jointed system for delivering a medical device to a target location within a human anatomy, comprising: a first segment that is a hollow cylinder, wherein a first flange and a second flange are attached to the distal end and extend distally away from the first segment; a second segment that is a hollow cylinder and has a proximal end and a distal end, wherein a third flange and a fourth flange are attached to the proximal end and extend proximally away from the second segment; a connector element having four cylindrical lugs extending radially away from a central point, wherein each lug passes, respectively, through a circular hole, and further wherein the connector element defines at least two separate openings extending in a direction from the distal end of the first segment to the proximal end of the second segment.

摘要： A stent or scaffold has a tapered end or ends. The scaffold is made using an additive manufacturing technique such as stereolithography (SLA). The scaffold may take the shape of a frustum, or a scaffold having one or both of its ends flared. The scaffold has varying mechanical properties over its length, such as a varying ring stiffness, porosity or elasticity modulus. In one embodiment the strut and link widths change linearly from the distal to proximal ends.

摘要： A method of stimulating a renal nerve in a human patient comprising, selecting a span of renal artery in the patient for implantation of a self-expanding stent, the artery having a first internal diameter, an artery wall, and being surrounded by peri-adventitial space through which at least one renal nerve extends; measuring the first internal diameter; selecting a self-expanding stent configured to be capable of expanding to have a second diameter that, in an expanded condition once implanted within the artery, is between 2 mm and 4 mm larger than the first diameter; implanting the stent in the span of the renal artery, whereby the stent eventually expands to the second diameter and thereby passes through the artery wall to become embedded in peri-advential space; and at least partially blocking the renal nerve or modulating a function of the nerve.

摘要： 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.

摘要： 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.
