  • Patent number: 11911224
    Abstract: A tissue expander is disclosed herein. The tissue expander may comprise a shell defining a chamber, and having a flexible wall and a port disposed through the flexible wall. The shell may also include a channel disposed through the flexible wall. A first syringe containing a first volume of a liquid may be connected to the chamber of the tissue expander via the channel. A second syringe containing a second volume of the liquid may be connected to the chamber via the port at least approximately one week after the first volume of liquid is injected. The first volume of liquid may be injected more quickly than the second volume of liquid.

  • Patent number: 9839738
    Abstract: In various embodiments, a cannula device includes an irrigation handpiece portion (with a first aspiration tip for aspiration and an irrigation fluid outlet for irrigation) and an aspiration handpiece portion (configured to aspirate fluid into a second aspiration tip that extends from a distal end of the aspiration handpiece portion). The cannula device is transformable between: (a) a coaxial mode in which the aspiration handpiece portion is coupled to the irrigation handpiece portion such that fluid is aspirated through the first aspiration tip and then the second aspiration tip in series and irrigation fluid is provided through the irrigation fluid outlet, and (b) a bimanual mode in which the aspiration handpiece portion is separated from the irrigation handpiece portion to provide aspiration through the second aspiration tip while the irrigation handpiece portion continues to provide irrigation fluid through the irrigation fluid outlet.

  • Publication number: 20080125712
    Abstract: An ophthalmic injection system is disclosed. The system has a dispensing member, a plunger, an actuation chamber, a lock mechanism, a lock stop, a port, a source of pressurized gas, and a shaft. The lock mechanism travels in the actuation chamber in an axial direction toward and away from a distal end of the dispensing member. The lock stop is located on the inner surface of the actuation chamber. The lock stop is engageable with the lock mechanism such that when the lock mechanism travels in the axial direction toward the distal end of the dispensing member to a first position located on a distal side of the lock stop, the lock mechanism cannot travel in a reverse direction away from the distal end of the dispensing member to a location on a proximal side of the lock stop.

  • Publication number: 20080097379
    Abstract: A method is disclosed for delivering a quantity of a substance into an eye. By applying compressed gas into an actuation chamber, a separating member connected to a lock mechanism and a plunger is displaced. The plunger displaces the quantity of the substance from a dispensing member and into an eye. The plunger is retained in an extended position so that the quantity of the substance is not retracted back into the dispensing member when the dispensing member is removed from the eye.

  • Patent number: 6661647
    Abstract: An apparatus (26) for mounting a display screen (28) to a printed circuit board (32). The display screen (28) has four edges. The apparatus (26) includes a top member (34) opposed to a bottom member (36), and first and second snap-fit members (40). The top member (34) and the bottom member (36) each form an overhang (38), wherein each overhang (38) is adapted to receive an edge (30) of the display screen (28). The first snap-fit member (40) is connected with and extended outwards from the top member (34). The second snap-fit member (40) is also connected with and extended outwards from the bottom member (36). Both the first and the second snap-fit members (40) are adapted to connect with the printed circuit board (32) for snap-fit assembly of the mounting apparatus (26) to the printed circuit board (32).
