  • Patent number: 10383999
    Abstract: A method of dispensing fluid includes three processes. A first one of these processes includes pumping fluid into a resilient variable-volume dispensing chamber. The dispensing chamber is in series with a normally present finite fluid impedance and an output. The impedance is sufficient so as to cause expansion of the dispensing chamber as it receives pumped fluid even while some fluid flows through the output. Another one of these processes includes repeatedly measuring a parameter related to volume of the dispensing chamber over time. A third one of these processes includes controlling the pumping of fluid based on repeated measurements of the parameter to produce a desired fluid flow through the output. A corresponding system for dispensing fluid implements these processes.

  • Patent number: 9545472
    Abstract: An extracorporeal reservoir device including a housing, a venous inlet sub-assembly, and a venous filter. The venous sub-assembly is mounted to the housing and includes a downtube and a luer port connector body. The connector body extends from the downtube and forms a passageway open to a lumen of the downtube. The connector body is arranged such that fluid flow from the passageway merges with a flow path of fluid along the primary lumen at an angle of less than 90°. Secondary blood flow through the port connector body is less likely to induce turbulent flow into venous blood flow within the downtube, and is thus less likely to break up any bubbles carried by the venous blood. For example, at port flow rates of less than 500 mL/minute, fluid flow from the port connector body does not induce turbulent flow into fluid flowing through the primary lumen.

  • Patent number: 8876751
    Abstract: In various embodiments, a handpiece may include an irrigation line coupled to an adjacent line reservoir with a piston configured to move within the adjacent line reservoir to increase an irrigation pressure in the irrigation line near a surgical site. In some embodiments, a sensor may be used to detect an occlusion break in the aspiration line and information from the sensor may result in signaling an actuator to move the piston in response to the occlusion break detection to compensate for a vacuum pressure drop associated with the occlusion break. The handpiece may further include a purge bypass line between the irrigation line and the adjacent line reservoir to allow flow from the irrigation line to travel through the adjacent line reservoir to purge the adjacent line reservoir.

  • Patent number: 8864709
    Abstract: In a medical liquid supply device, a control unit controls a liquid supply driver so that a liquid flows from the liquid supply driver in a liquid supply path regardless of whether a liquid-supply ON mode is selected. All of the liquid flowing from the liquid supply driver flows into a communication path when the liquid-supply ON mode is not selected. At least a part of the liquid flowing from the liquid supply driver does not flow into the communication path and is thereby supplied from a distal end of the liquid supply path when the liquid-supply ON mode is selected.

  • Patent number: 8852139
    Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

  • Patent number: 8840601
    Abstract: Disrupting tissue and devices and systems for disrupting tissue. The disclosure describes ways to deliver moieties to a target tissue, where the target tissue in general is not at the point of introduction, in such a way that minimal damage is produced in the tissue at the point of introduction. In some embodiments this is accomplished by jetting fluid at high velocity into the target tissue. The disclosure further describes novel agents deliverable in such systems for use in remodeling tissues. Some of these agents comprise a liquid while others do not. Additionally, although not specifically described in detail much of the disclosure may additionally be used in the delivery of therapeutic drugs.

  • Patent number: 8801654
    Abstract: A pressure and a vision regulation method and device for irrigation of a body cavity (1), in which an inflow liquid pump (2) pressurizes the irrigation liquid in a feed line (13) and an outflow device (3) or an external suction source (20) drains the irrigation liquid from the body cavity (1) through a tubing (16) into a waste container (17). A control unit (4) controls either the inflow liquid pump (2) only or both the inflow liquid pump (2) and the outflow device (3) depending on an inflow irrigation liquid pressure from a pressure sensor (5). The method and the device are combined with a method for detecting blood cells, red blood cells, haemoglobin and/or debris in liquid coming from a surgical site to provide an automatic control and rinsing system with clear vision in the viewing area of the operational site.
