A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

Filtering device for filtering cerebrospinal fluid are disclosed. An example filtering device may include a filter housing having an inlet for receiving cerebrospinal fluid from a patient and an outlet for returning filtered cerebrospinal fluid to the patient. The filter housing may include a plurality of layers coupled together and defining a fluid pathway therein between the inlet and the outlet. A filtering section may be defined within the filter housing along the fluid pathway. The filtering section may include a widened region of the fluid pathway that is configured to slow the passage of fluid therethrough.

Methods of harvesting cancellous bone and bone marrow include extracting loosened cancellous bone and bone marrow—including a liquid component thereof—to a collection container that has a first cup and a suction port to which a suction source is connected. After extraction, the suction source is disconnected and a lid of the collection container is removed and replaced with a lid having a plunger with a press head that is configured to filter the extracted liquid by depressing the plunger toward a bottom of the first cup. The filtered liquid is poured through a suction port into a second cup while depressing the plunger, thereby separating the liquid from a semi-solid mass of cancellous bone that remains. The bone is extracted through a cortical opening in the femur, tibia, or calcaneus, or from an intermedullary canal that is preferably formed by reaming of the tibia using an orthopedic reamer.

Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed. A system for processing cerebrospinal fluid is disclosed. The system may include a catheter having a proximal subassembly and a distal subassembly. A pump and filtration system may be coupled to the catheter. An infusion lumen for infusing cerebrospinal fluid filtered by the pump and filtration system may be defined along the distal subassembly. The distal subassembly may define a plurality of infusion openings in fluid communication with the infusion lumen. The infusion openings may increase in size distally along the distal subassembly.

An apparatus and method for collecting fluid are disclosed. The apparatus includes a body portion comprising a fluid inlet and an outlet, an expandable container secured to the body portion, at least one wicking element extending from within the body portion into the container, and at least one super absorber element arranged inside the container.

A syringe for withdrawing an aspirate from a body for micro fat grafting is provided. The syringe includes a barrel having an inner wall extending therein. The inner wall has one or more apertures formed therein allowing the aspirate to contact an absorbent positioned between the inner wall and an outer wall of the barrel. A plunger moves longitudinally within the barrel along the inner wall and has a gasket attached to a proximal end forming a seal against the inner wall. The absorbent may take many forms to absorb a non-fat cell portion of the aspirate. A related method includes retracting the plunger from a first position to draw the aspirate from a harvest site of a body into the barrel, exposing the aspirate to the absorbent, and moving the plunger toward the first position so a remaining portion of the aspirate is no longer exposed to the absorbent.

A fluid collection apparatus for use in negative pressure wound therapy. The fluid collection apparatus includes a flexible bag having a first opening and a second opening. The bag includes a structure defining a fluid pathway connecting the first opening and the second opening. The pathway is circulative and contributes to orientation independence of the bag in use. The bag further includes a load-bearing component.

Disclosed are saliva collection containers comprising a removable cartridge containing a liquid absorbent material, the removable cartridge adapted to receive saliva from a user; a suction source removably disposed therein and fluidly coupled to the removable cartridge, wherein the saliva collection container is adapted to receive the removable cartridge; and a tubing having a first end and second end opposite of the first end, wherein the first end of the tubing is fluidly coupled to the suction source through an opening in the neck of the saliva collection container. Disclosed are saliva collection containers comprising a cartridge containing a liquid absorbent material, the cartridge adapted to fit inside a tubing; a tubing having a first end and second end opposite of the first end, wherein the first end of the tubing is fluidly coupled to the suction source; wherein the tubing is adapted to receive the cartridge; and a suction source removably disposed therein and fluidly coupled to the tubing.

A treatment system for applying negative pressure to a tissue site in conjunction with a venting or purging capability. In some embodiments, the treatment system may include a reduced-pressure source, an inline storage pouch, a purge chamber, and a dressing. Reduced-pressure may be supplied to the inline storage pouch and the dressing, while the purge chamber may provide a ventilation opening to the atmosphere.

Disclosed is a covering/lid assembly having a first compartment, a second compartment, or both. Each compartment will comprise a top side and a bottom side, the bottom side of the compartment comprising a frangible material. The first or second compartment may comprise a first material or a second material. The first or second material may comprise a flocculated red blood cell coagulant, or a red blood cell flocculent. The material within a compartment may be selectively released upon compressing a dimple and/or button located directly above the first and/or second compartment. A collection and/or biological waste management and disposal system is presented, comprising a lid/covering assembly as described and a collection container. The lid may include a perimeter having a threaded and/or snap-on assembly suitable for securely attaching the lid to a collection canister. The collection canister may comprise a red blood cell flocculent coating.
