  • Patent number: 10420872
    Abstract: The degassing system can include a degassing vessel and can utilize a vacuum pump and a fluid pump located downstream of the degassing vessel to control the pressure within the degassing vessel in order to control the concentration of gases in fluid exiting the degassing system. The degassing system can further comprise sensors in communication with the pumps to control the rate of flow and pressure through the degassing system. The degassing system may be placed in a dialysate flow path to remove dissolved gases including carbon dioxide from the dialysate.

  • Patent number: 10219936
    Abstract: An apparatus for delivering therapeutic agent to an eye comprises a body, a cannula, a hollow needle, a cannula actuation assembly, and a needle actuation assembly. The cannula extends distally from the body and is sized and configured to be insertable between a choroid and a sclera of a patient's eye. The cannula actuation assembly is operable to actuate the cannula relative to the body. The needle actuation assembly is operable to actuate the needle relative to the cannula. The cannula may be inserted through a sclerotomy to position a distal end of the cannula at a posterior region of the eye, between the choroid and sclera. The needle may be advanced through the choroid to deliver the therapeutic agent adjacent to the potential space between the neurosensory retina and the retinal pigment epithelium layer, adjacent to the area of geographic atrophy.

  • Publication number: 20190038824
    Abstract: A blood based solute monitoring system for measuring at least one blood solute species that has a first recirculation flow path in fluid communication with a dialyzer. The first recirculation flow path is configured to allow a fluid to recirculate through a dialyzer such that the concentration of at least one solute species in the fluid becomes equilibrated to the solute species concentration of the blood in a blood compartment of the dialyzer. The blood solute monitoring system has at least one sensor to measure a fluid characteristic.

  • Patent number: 10195327
    Abstract: A sensing and storage system for fluid balance during dialysis is provided. The sensing and storage system has flow sensors on either side of a dialyzer in a controlled volume dialysate flow path. The sensors are positioned so that no fluid can be added to or removed from the dialysate flow path between the sensors except for that which is added or removed by action of a control pump. The sensing and storage system can have a fluid removal line for the removal of fluid from the dialysate flow loop.

  • Publication number: 20180289540
    Abstract: An apparatus has a first fluid conduit, a second fluid conduit, a connector member, an first tubular member, a second tubular member, and an inner cannula. The connector member has first and second passageways in which the first and second fluid conduits are positioned, respectively. A portion of the second tubular member is positioned within the lumen of the first tubular member. A proximal portion of the inner cannula is fixedly secured within the lumen of the first tubular member. The inner cannula lumen is in fluid communication with the first and second fluid conduits via the lumen of the first tubular member and the lumen of the second tubular member. The inner cannula may be inserted into the subretinal space of a human eye to deliver a leading bleb of fluid and then deliver a therapeutic agent, without having to withdraw the inner cannula from the subretinal space between the acts of delivering the leading bleb delivering the therapeutic agent.

  • Patent number: 10071323
    Abstract: This disclosure generally relates to at least one reusable module of a sorbent cartridge in a sorbent dialysis system and a method of using the same. One of the drawbacks of a conventional sorbent dialysis system is the high cost. In one aspect of the invention, the sorbent cartridge contains at least one module for optionally recharging sorbent materials in-line with an optional bypass and conduits for the sorbent cartridge. The sorbent cartridge can have two or more modules that are connected to one another through connectors. The modules can be reusable and the sorbent materials contained in the modules can be recharged.

  • Patent number: 10010663
    Abstract: A flow loop for hemodialysis, hemodiafiltration and hemofiltration for the treatment of pathological conditions such as End Stage Renal Disease (ESRD) that has a controlled compliant flow path for preparing fluids required for a hemodialysis therapy session from water. The controlled compliant flow path modifies water into any one of a solution for priming a hemodialysis system, a physiologically compatible solution for contacting blood, a physiologically compatible solution for infusion to a subject, and a solution for blood rinse back to a subject. The controlled compliant flow path has a means for selectively metering in and metering out fluid from the flow path.
