Abstract: A stent includes a plurality of unit cells. Within each unit cell, a first set of struts define a first plurality of apices and a second set of struts define a second plurality of apices, wherein a first strut and a second strut of the first set of struts define a first apex with a first apex angle, and the second strut and a third strut of the first set of struts define a second apex with a second, different apex angle. Within each unit cell, a fourth strut and a fifth strut of the second set of struts define a third apex with the first apex angle, and the fifth strut and the sixth strut define a fourth apex with the second apex angle. Each apex of the first plurality of apices is circumferentially offset from another apex of the second plurality of apices.

Abstract: An online voltage control method for coordinating multi-type reactive power resources is provided. First, a linearized power flow equation of branch reactive power is established, and an online voltage control model of multi-type reactive power resources including an objective function and constraint conditions is constructed. The constraint conditions includes generator reactive power constraints, reactive power compensator constraints, transformer tap position constraints, a nodal reactive power balance constraint, and slack contained nodal voltage constraints. Then, an optimization result of voltage control is obtained by solving the model.

Abstract: A delivery guidewire (100), comprising: a core wire (110) comprising a first segment (111), a second segment (112) and a third segment (113), which are arranged in sequence and have diameters decreasing in the direction from a distal end to a proximal end of the delivery guidewire (100); a metal ring (130) at least partially disposed at a proximal end of the first segment (111); and a spring (120) at least partially disposed over the outer side of the second segment (112). A distal end of the spring (120) abuts against a proximal end of the metal ring (130), and a distal section of the spring (120) has a diameter smaller than a diameter of a proximal section thereof. The diameter of the distal section of the spring (120) that is smaller than the diameter of the proximal section of the spring (120) results in a smaller clearance between the distal section of the spring (120) and the core wire (110), which enables greater concentricity of the distal section of the spring (120) with the core wire (110).

Abstract: A multifunctional lamp mounting box includes a mounting plate defining a plurality of mounting holes; a connecting member, wherein one end of the connecting member is connected to the mounting holes, and the other end of the connecting member is connected to a mounting base; a housing, wherein an upper part of the housing is detachably connected to the mounting plate, and a lower part of the housing defines an accommodating cavity; and a lamp holder detachably mounted in the accommodating cavity and configured to connect a lamp.

Abstract: A vascular implant and a medical device. The vascular implant includes a tubular implant main segment (100, 400) braided from two or more interlaced wires (130, 132, 134, 136, 138) and having a first end (120, 420) and a second end (110, 410), which are located at two ends of g an axis of the implant main segment. The first end (120, 420) includes a plurality of looped-back rings (122, 124, 422, 424). The second end (110) includes a plurality of first joint portions (112), each of which is a non-invasive joint portion formed by joining at least two of the wires (130, 132, 134, 136, 138). At least one of the two or more wires (130, 132, 134, 136, 138) includes core and a jacket surrounding the core. The ends of the vascular implant will cause less damage to the wall of a blood vessel, and the implant provides improved stability and radiopacity.

Abstract: A lamp includes a mounting part configured to be capable of being mounted on a fixture, a lamp part, and two locking parts arranged on the lamp part. The mounting part includes two locking portions and each of the two locking portions have two first fastening elements arranged on two opposite ends thereof. Each of the locking part defines two slot assemblies corresponding to the first fastening elements.
