A system for performing an endoscopic surgical procedure in a surgical cavity is disclosed which includes a primary gas circulation device housing a central processor and a primary pump, the primary pump controlled by the central processor and configured to deliver a flow of pressurized gas to a primary gas delivery lumen and to receive gas from a primary gas return lumen, and a plurality of subordinate gas circulation devices each housing a respective subordinate pump configured to deliver a flow of pressurized gas to a respective subordinate gas delivery lumen and to receive gas from a respective subordinate gas return lumen, wherein the subordinate pump in each subordinate gas circulation device is in networked communication with and controlled by the central processor of the primary gas circulation device.

Filtering cassettes, filtering systems, and methods for using the same are disclosed. An example filtering cassette may include a cassette housing. An inlet may be coupled to the cassette housing. The inlet may be configured to receive cerebrospinal fluid from a catheter. An outlet may be coupled to the cassette housing. The outlet may be configured to direct filtered cerebrospinal fluid to the catheter. One or more filters may be disposed within the cassette housing. An arcuate surface may be defined along a periphery of the cassette housing. The arcuate surface may be configured to engage a controller assembly when the cassette housing is mounted to the controller assembly.

Embodiments of the present disclosure include a dialysis system having a disposable cartridge which includes one or more flowpaths arranged on or within the cartridge.

A method of managing cancer in a patient’s cerebrospinal fluid (“CSF”) forms a fluid circuit by fluidly communicating a set of catheters (“a catheter”) with the patient’s brain ventricle and the patient’s lumbar and, while controlling the flow rate of the CSF through the CSF fluid circuit, filters cancer cells from the CSF through the fluid circuit. The method also determines both a variable indicative of cancer cell concentration in the CSF, and at some point, that the variable has attained or passed through a threshold value (e.g., greater than a maximum threshold value or below a minimum threshold value). The method stops controlling the CSF flow rate in response to the variable attaining and/or passing through the threshold value. The CSF flow rate therefore preferably returns to a natural CSF flow rate of the patient after stopping control of the CSF flow rate. A system preferably performs these acts.

Methods of assembling a manifold for a medical waste collection system. A flapper valve unit is secured to a head of a cap. A filter element is positioned within a shell. Basket hands of the filter element are fitted between first pairs of ribs of the cap skirt. Fingers of the shell are fitted between second pairs of ribs of the cap skirt. The cap is secured to the shell to cover an open distal end of the shell. A drip stop is secured to the proximal end base of the shell to seat within the outlet opening. Ears may be fitted through holes defined by the flapper valve unit and cap holes defined by the cap so as to snap lock to the head of the cap. The hub of the flapper valve unit may be compressed with the ears snap locked to the head of the cap.

A manifold for a medical/surgical waste collection system. An outlet opening and a fitting are in fluid communication with a manifold volume within a housing. The fitting receives a suction line. A filter element with porous features is disposed within the housing such that a fluid communication path is established across the filter element. The porous features trap material entrained within the fluid. A material collection volume is at least partially distal to and below a bottom of the filter element. As the fluid and the material is drawn through the fluid communication path, the material collects within the material collection volume. A flow diverter may be positioned within the housing for directing the material towards the material collection volume. The material collection volume may be at least partially defined by a tissue trap removably coupled to the housing.

An emergency ventilator for artificially ventilating patients in the event of a medical emergency, having: —a housing with an ambient air suction opening and a ventilating gas outlet opening and —a fan which is designed and is arranged in the housing so as to convey ambient air from the ambient air suction opening to the ventilating gas outlet opening, wherein the fan includes a fan housing with an air conveyor which can be moved relative to the fan housing, and the fan housing is arranged in the housing in a fixed manner thereto; the fan housing is secured to the housing with the interposition of a heat conducting body, the heat conducting body including or being made of a material which is selected from light metal, nonferrous metal, and/or a plastic filled with a heat-conductive filler material.

A vaporizer pod comprises a reservoir defined by, and disposed within a housing, wherein the housing defines a central channel extending between a central channel inlet and a central channel outlet, a column disposed within the housing, an atomizer channel extending between an atomizer channel inlet and an atomizer channel outlet, a heat conductor disposed within the column, and a heat-conducting filter disposed within the column.

Biological fluid processing cassettes with integrated filter structures are disclosed. A cassette body is formed of a generally rigid material, defining a plurality of internal fluid flow paths. The cassette body may be secured to a cassette cap to define a cavity, with a filter sealed within the cavity. Each of the cassette body and the cassette cap defines a port opening into the cavity, which allows fluid to flow from one of the internal fluid flow paths, into the cavity and through the filter, and then out of the cavity via the port of the cassette cap. Alternatively, the cassette body may define an external slot which receives at least a portion of a filter. Such a filter includes two ports, with one of the ports in fluid communication with a cassette port of the cassette body to allow fluid flow between the cassette body and the filter.

An apheresis system may include an assembly for separating a component from a multi-component fluid, a processor, and a memory storing data for processing by the processor. The data, when processed, may cause the processor to run a calibration test on one or more instruments of the assembly and, based the one or more instruments failing the calibration test, calibrate the one or more instruments or lock the apheresis system for non-use. The apheresis system may include a pump configured to generate a calibration pressure at a test port and a pressure sensor configured to sense a pressure at the test port. The calibration test may include comparing the calibration pressure at the test port to the sensed pressure by the pressure sensor at the test port.
