System for providing continual drainage in negative pressure wound therapy
A system for subatmospheric pressure therapy in connection with healing a wound is provided. The system includes a wound dressing cover dimensioned for positioning relative to a wound bed of a subject to establish a reservoir over the wound bed in which subatmospheric pressure may be maintained, a subatmospheric pressure mechanism including, a housing, a vacuum source disposed in the housing, and a collection canister in fluid communication with the vacuum source. The system further includes an exudate conduit in fluid communication with the wound dressing and the collection canister for collecting exudate removed from the reservoir and deposited in the collection canister under influence of the vacuum source and a vent conduit in fluid communication with the collection canister and the wound dressing for introducing air into the reservoir to facilitate flow of exudate through the exudate conduit.
SYSTEMS AND METHODS FOR THE PREPARATION OF ENRICHED SERUM
Systems and methods for preparing enriched biological samples, and methods of use thereof are described herein. The systems can include a containment device connected to a first insert to collect tissue fragments in the containment device or to a second insert to incubate tissue fragments with a blood sample in the containment device. The methods can include methods for preparing a cytokine or growth factor-enriched biological sample, such as IL-1 Ra-enriched serum, methods of treating inflammation, inflammatory joint, or rheumatoid arthritis, and methods of preventing inflammation of a joint following arthroscopic surgery.
METHOD FOR PREPARING TISSUE, PARTICULARLY ADIPOSE TISSUE, FOR TRANSPLANTATION FROM LOBULAR FAT EXTRACTED BY LIPOSUCTION
A method of preparing adipose tissue for transplantation, from lobular fat extracted, for instance, by liposuction, said fat consisting of a fluid component comprising an oily component, a blood component and/or sterile solutions and of a solid component comprising cell fragments, cells and one or more cell macroagglomerates of heterogeneous size, characterized in that it includes at least one step of forming an emulsion of the fluid component in the sterile washing solution by means of active and/or passive stirring means and discharging the emulsion from the outlet through a density gradient.
REDUCED-PRESSURE SYSTEMS AND METHODS EMPLOYING AN ULTRAVIOLET LIGHT SOURCE FOR REDUCING BIOBURDEN
Systems and methods are provided for moving fluids from a patient to a canister and lowering or eliminating the bio-burden of the canister. In one instance, a method for removing fluids from a patient includes using reduced pressure to remove fluids from a patient, delivering the fluids into a reduced-pressure conduit and into a fluid reservoir, exposing the fluids removed from the patient to a UV light source to kill pathogens to create disposable fluids, and disposing of the disposable fluids. Other systems, devices, and methods are presented.
Tissue processing apparatus and method for processing adipose tissue
A portable apparatus useful for collection and processing of human biological material, such as adipose or cancellous bone material, to prepare a concentrated product (e.g., stromal vascular fraction). The apparatus has a container with a containment volume with a tissue retention volume and a filtrate volume separated by a filter and with a pellet well for collecting concentrate product in the form of a pellet phase from centrifuge processing. The pellet well is accessible only from above when the apparatus is in an access orientation. Collected pellet phase material may be removed from the pellet well by direct aspiration, without suspending the material in a suspension liquid within the container. Access ports may be configured for access only from above the container. The apparatus may include a tissue collector disposed in the disuse retention volume to engage and collect collagen or other stringy tissue. A method of processing adipose tissue to concentrate leuko stromal vascular cells includes multi-step processing using a portable container.
Collection Jar and Collection Basket for Surgical Use
A surgical collection assembly for filtering material from liquid obtained during surgery. A jar having an inlet and an outlet each adapted for connection to a suction line. A set of orientation features to position an upper portion of a collection basket within the jar such that an upper portion of the collection basket does not impede a flow of material entering the jar through the inlet. A bottom surface with a pattern of recessed paths in the bottom surface, the pattern of recessed paths connected to the outlet. A plunger assembly that may be reversibly attached to the jar so that a distal end of a plunger may be used to compress collected material within the collection basket to help remove fluid from the collected material. For certain uses, the surgical collection assembly may have a simple jar lid without an integrated plunger.
COLLECTION OF AMNIOTIC FLUID FOR WOUND HEALING
Disclosed are a method of wound healing and an apparatus for the collection, processing and application of amniotic fluid at a wound site to improve healing. The apparatus includes a canister or bag positioned along the vacuum line through which the amniotic fluid and placental aspirate is suctioned. The canister or bag also has a sterile syringe port, through which amniotic fluid can be extracted and later processed. The processed material can then be applied to the wound site of the patient. The apparatus and method disclosed allow for the processing of the amniotic fluid to take place in the same room as the surgical procedure. A kit is provided but not limited to including an amnion rupture tool, a canister or bag for collection, Yankauer suction tip, tubing, and a dual syringe mixing sprayer for reapplication.
System and method for harvesting autologous adipose tissue
A triple-chambered container includes: a main container body with a first chamber which has an opening at its distal end; a main barrel formed and movable longitudinally within the first chamber, the main barrel defining therein a second chamber for receiving fluids, the main barrel further having an apertured stopper at its distal end; a second barrel formed within the main barrel, the second barrel defining a third chamber for receiving fluids, the second barrel being movable longitudinally within and with respect to the main barrel, the second barrel having a distal end which is engageable and disengageable with the apertured stopper; a shaft adapted to fit within the second barrel, the shaft being movable longitudinally within and with respect to the second barrel, the shaft having a distal end which is engageable and disengageable with an aperture in the second barrel; a device for controlling engaging and disengaging of the distal end of the shaft with the aperture of the second barrel. The first chamber, the second chamber and the third chamber may be selectively moved to receive and discharge fluids with respect to one another.
Filtering systems and filtering manifolds for use with filtering systems
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.
FLUID FLOW SENSING
Devices and methods for collecting and sensing fluid flow are provided.
