  • Publication number: 20230414101
    Abstract: An apparatus to treat, inhibit, or prevent an eye condition in a patient can include a cover, sized and shaped to fit over an eye of a patient to define a cavity between the cover and an anterior surface of the eye when the cover is located over the patient eye. The apparatus can include a pressure source, in communication with the cavity, capable of applying non-ambient pressure in the cavity. The apparatus can include control circuitry, in communication with the pressure source, configured to vary non-ambient pressure applied to the cavity to affect a targeted pressure relationship between an indication of a first physiological pressure level and a second physiological pressure level associated with the eye of the patient.

  • Patent number: 10285833
    Abstract: Stent delivery systems and associated methods for delivering stents are disclosed herein. In several embodiments, a handle assembly for delivering a stent from a tubular enclosure can include a first lead screw having a first lead thread of a first pitch and first handedness, a second lead screw having a second lead thread of a second pitch and second handedness different from the first handedness, and a housing defining threads of the first and second pitches. The first lead screw can be in mechanical communication with the tubular enclosure, and the second lead screw can be in mechanical communication with the stent. Upon rotation of a portion of the housing, the housing threads can engage the lead screws so as to induce simultaneous translations of the lead screws in opposite directions. The simultaneous translations are configured to deploy the stent from the tubular enclosure.

  • Publication number: 20180209596
    Abstract: A cloak-shaped net mesh lighting string is in a state of being spread out on a plane and includes multiple first strings and multiple second strings. Each first string has a top end and a bottom end opposite to the top end, and the bottom ends of the first string are spaced apart from each other. The multiple second strings are spaced apart from each other and are tied to each first string to constitute the form of a net mesh. Each second string has multiple bulbs connected thereto and a resistor kit connected thereto and mounted next to one of the bulbs. At least one of the multiple first strings is an electrical wire for transmitting power to each second string. The remaining first strings are tied to the multiple second strings to keep each adjacent two of the multiple second strings to be spaced apart.

  • Publication number: 20180206663
    Abstract: An artificial Christmas tree includes a foot stand, a trunk, multiple branches and multiple leaves. One end of the trunk is connected with the foot stand. The trunk has multiple branch holders. Each branch is formed by sheathing plastic around an iron wire and is flexible and bendable. One end of each branch is connected with a corresponding branch holder of the trunk and each branch has multiple leafstalk seats formed around a periphery of the branch for corresponding leaves to be mounted on the leafstalk seats. Each leaf has a resilient metal wire sheathed by plastic and has multiple leaflets formed on the sheathed metal wire. As the leaves can be short or long and can be sequentially spread out after mounted on corresponding branches, a Christmas tree structure with simple and easy assembly and three-dimensional spatial perception to viewers can be attained.
