  • Patent number: 10201441
    Abstract: A ureteral stent includes an elongated member, which has a tubular shape, and a distal retention structure. The elongated member includes a sidewall that defines a lumen and has a spiral-shaped opening with at least two rotations. The sidewall has an inner surface and an outer surface. The sidewall between the inner surface and the outer surface is devoid of another lumen. The elongated member is configured to move between a retracted configuration and an expanded configuration along a longitudinal axis of the lumen. The distal retention structure is disposed at a distal end of the elongated member for retention in a kidney. The distal retention structure defines a lumen in fluid communication with the lumen defined by the sidewall of the elongated member.

  • Patent number: 10195081
    Abstract: A method of preventing capsular opacification and fibrosis after cataract extraction and and/or preventing fibrosis around a shunt or stent after glaucoma surgery is disclosed herein. In the cataract procedure, after the cortex and nucleus of the natural lens with the cataract has been removed, a photosensitizer is applied inside the lens capsule, a posterior portion of the lens capsule is irradiated so as to activate cross-linkers and prevent capsular opacification and fibrosis, and an intraocular lens is inserted into the lens capsule. In the glaucoma procedure, a fluid drainage opening is formed and/or a stent is inserted into the eye, a photosensitizer is applied inside an anterior chamber of the eye so that a diffused stream of the photosensitizer travels through the fluid drainage opening or the stent, and the tissue surrounding the fluid drainage opening or the stent is irradiated so as to activate cross-linkers and prevent fibrosis.

  • Patent number: 10064626
    Abstract: Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. A damping device configured in accordance with embodiments of the present technology can include an anchoring member coupled to a flexible, compliant damping member including a generally tubular sidewall having an outer surface, an inner surface defining a lumen configured to direct blood flow, a first end portion and a second end portion, and a damping region between the first and second end portions. The inner and outer surfaces of the damping member can be spaced apart by a distance greater at the damping region than at the first or second end portions. When blood flows through the damping member during systole, the damping member absorbs a portion of the pulsatile energy of the blood, thereby reducing a magnitude of the pulse pressure transmitted to a portion of the blood vessel distal to the damping device.
