  • Publication number: 20240090889
    Abstract: An implant system includes an implant having a body having a proximal end, a distal end, a central cavity disposed between the proximal and distal end, and a proximal end opening disposed proximal to the central cavity. A toggle is at least partially housed within the central cavity and connected to the body by a toggle hinge connection, the toggle having a toggle lumen extending therethrough. An inserter includes an inserter lumen, and an actuator having a distal actuator tip configured to advance into the proximal end opening. An implant system, kit, method for placing an implant device, devices and systems using a pivot suture, suture loading device and related surgical procedures are also disclosed.

  • Patent number: 5492621
    Abstract: Sewage water with entrained solids as an effluent is fed into the trough bottom shaped process tank that is a totally enclosed tank other than for inlets and outlets therefore. The system disposes of water from sewage effluents and also residual solids thereof and is fed sewage to a controlled depth in a tank trough with high temperatures used to sterilize the effluent. A two-speed motor driven mixer driven at low speed continually mixes and blend the sewage effluent at the same time air from a blower is bubbled through the mixture. Heat is added to increase water vapor saturation capability of the air flow through the system. The air/vapor mixture flows through a recuperative heat exchanger supported within the tank above the surface of sewage effluent contained therein, absorbing heat with flow, through a catalyst bed in a chamber with circulation through the heat exchanger and on out an exhaust vent with impurities oxidized and vented with air flow.

  • Patent number: 4920236
    Abstract: To seal a cable junction, an insert is placed between two branch cables of the junction, which is then enclosed by a heat shrinkable envelope. The insert has at least one insert part having a block of heat fusible material attached by one or more flanges of heat conductive material to the branch cables. The block lies between the branch cables at least partially inside the envelope. Then, when the envelope is heated to cause it to shrink, the block fuses, thus forming a seal. For most sizes of branch cables, two insert parts may be used, but three or more may be used for large branch cables. The flange preferably has a tongue extending into the block to assist heat conduction.
