  • Publication number: 20210121169
    Abstract: An assembly includes a flexible fixation member, a suture, and a delivery device. The fixation member includes a body with two terminal ends. A suture passes through the flexible fixation member at various points along a length of the body such that portions of the fixation member are slidable relative to the suture and configurable to form a cluster within a surgical site. The delivery device includes a tubular member, an elongated inserter, and a trigger. The elongated inserter is slidably disposed within the tubular member. The inserter has a forked distal end configured to receive a portion of the flexible fixation member and the suture. The trigger is finger-engagable and fixedly coupled to the proximal end of the inserter. It is configured to advance and retract the inserter relative to the tubular member. The trigger includes a retention member for retaining a proximal end portion of the suture.

  • Publication number: 20200354240
    Abstract: Electro oxidation membrane evaporator 1 comprises sweep air handler 60; fluid tank 20 defining a fluid container; fluid contactor/separator 30; oxidation cell 40; and scrubber 80. Electro oxidation membrane evaporator 1 may allow higher percent water recovery from wastewater prior to delivering brine to a brine water recovery system and can allow O2 from air such as cabin air to continuously diffuse into the wastewater as O2 is consumed to generate oxidants, helping to eliminate the low oxidant environment at the end of the cycle that causes pH to remain high, and low pH prevents precipitates from forming for longer so more water can be evaporated from the wastewater.

  • Patent number: 10693144
    Abstract: A method for producing a catalyst ink, by which the surface of a catalyst can be appropriately covered with an ionomer, and the power generation performance of a fuel cell can be excellent in a wide range of humidity environments, and a catalyst composite. The method for producing a catalyst ink may comprise the steps of, for a catalyst composite in which a catalyst is supported on a carbon support with pores, controlling a hydrophilic pores rate of the carbon support to 60% to 80%, and dispersing an ionomer in the catalyst composite after the controlling step, wherein the hydrophilic pores rate is calculated by the following formula (1) using a contact porosimetry method: Hydrophilic pores rate (%)=(hydrophilic pores volume/total pores volume)×100.

  • Publication number: 20200179099
    Abstract: The present disclosure relates to an anchor. The anchor includes a suture bridge having a proximal end and distal end. The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.
