A system, method, and apparatus for treating a tissue site with reduced pressure includes a dressing adapted to be positioned proximate the tissue site. An absorbent may be adapted to be fluidly coupled to the manifold, and an ion exchange member may be adapted to be fluidly coupled between the manifold and the absorbent. A sealing member may be adapted to cover the tissue site to form a sealed space having the manifold disposed therein. A reduced-pressure source may be adapted to be fluidly coupled to the manifold.

A fat sizing device includes a first filter element and a second filter element. The first filter element has an exterior formed from a ceramic such as titanium nitride. The second filter element is positioned in series with the first filter element and has an exterior formed from an organic polymer such as a parylene. The first filter element has a first mesh size and the second filter element has a second mesh size different than the first mesh size and may be less than the first mesh size.

A system suitable for collecting and transporting urine away from the body of a person or animal may include an assembly having a fluid impermeable casing, a fluid permeable membrane, and a fluid permeable support. A reservoir is defined by the fluid permeable support. The fluid permeable membrane can define a cavity. The casing can define an opening such that the cavity is accessible via the opening. The assembly can also include an outlet in fluidic communication with the reservoir. The assembly can be arranged such that a user's penis can be disposed through the opening with the urethral opening disposed within the cavity and such that a fluid can flow into the body from the urethral opening of the user's penis, collect in the reservoir, and flow out of the outlet.

A device that allows for either fat graft preparation or cell fraction harvest is disclosed. The device includes a first centrifuge tube configured to receive and process a biological substance, the first centrifuge tube comprising an upper cylindrical portion and a lower conical portion, a sterile tissue inlet fitting, at least one sterile processing fluid inlet fitting, a sterile suction fitting, and at least one sterile extraction port connected to a first extraction tube. The first centrifuge tube further includes an internal space including a screen being positioned therein, the screen being configured to divide the internal space in half, and a filter positioned therein, the filter being positioned below the screen in the lower conical portion of the first centrifuge tube. The device may further include a second centrifuge tube configured to receive and further process the biological substance from the first centrifuge tube. The second centrifuge tube has at least one sterile fitting, wherein the second centrifuge tube is releasably connected via the at least one sterile fitting to one of the at least one sterile extraction ports of the first centrifuge tube.

A deagglomerator for use in resizing masses of cells is disclosed. The deagglomerator may include a plurality of apertures defined by a plurality of front and back edges. The masses of cells may be passed through the plurality of apertures from the front to the back, and from the back to the front, repeatedly. The deagglomerator may also include a plurality of blades that may aid in the deagglomeration of the cell masses. The deagglomerator may be configured between two syringes so that the tissue may be passed back and forth from the first syringe through the device to the second syringe, and then back again from the second syringe through the device and to the first syringe. In this way, the masses of cells may be properly deagglomerated.

The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.

Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. The method may include the steps of withdrawing fluid comprising CSF, filtering the volume into permeate and retentate by passing the fluid through a tangential flow filter, and returning the permeate to the subject. During operation of the system, various parameters may be modified, such as flow rate.

A portable pump is provided for negative pressure wound therapy for drawing a vacuum from a wound site via a tube. The pump includes an inlet configured to attach the tube from the wound site; a canister in fluid communication with the inlet for collecting fluids drained from the wound site; and a manually-actuated pump mechanism for creating the vacuum. The pump mechanism includes a vacuum chamber in fluid communication with the canister; a piston disposed in the vacuum chamber; and a pump handle coupled to the piston to move the piston in the vacuum chamber between first and second positions to create the vacuum. The pump handle moving between a retracted position and an extended position. The piston is in the first position when said pump handle is in the retracted position and is in the second position when said pump handle is in the extended position.
