Methods and devices are disclosed for processing stromal precursor cells (i.e., cells which can differentiate into connective tissue cells, such as in muscles, ligaments, or tendons) which can be obtained from fatty tissue extracts obtained via liposuction. Normal processing of a liposuction extract involves centrifugation, to concentrate the stromal cells into a semi-concentrated form called “spun fat”. That “spun fat” can then be treated by mechanical processing (such as pressure-driven extrusion through 0.5 mm holes) under conditions which can gently pry the stromal cells away from extra-cellular collagen fibers and other debris in the “spun fat”. The extruded mixture is then centrifuged again, to separate a highly-enriched population of stromal cells which is suited for injection back into the patient (along with platelet cells, if desired, to further promote tissue repair or regeneration).

The invention relates to a system for drainage of fluids or wound secretion from body and/or tissue openings of the human or animal body comprising a bag-like reservoir for collecting the fluid or wound secretion, with an upper inlet opening and a lower outlet opening, and a pre-evacuated container with an inlet opening, wherein the inlet opening of the pre-evacuated container is connected to the lower outlet opening of the bag-shaped reservoir.

An apparatus for treating a urinary retention of a patient by discharging urine from a mammal urinary bladder through a mammal urethra. The apparatus comprises an expandable member adapted to be implanted inside the urinary bladder of the patient, a control device adapted to control the volume of the expandable member for emptying the mammal urinary bladder, and an implantable restriction devices adapted to close each ureter of a patient when discharging urine from the urinary bladder.

This invention relates to the design of tissue covering elements for use in vacuum assisted tissue apposition systems, wherein the geometry of the covering elements favours the application of contractile forces over compressive or extensive forces at the tissue interface.

Systems, methods, and devices related to removing fluids from a patient are provided. In one instance, fluid is removed from the patient and delivered to a canister using reduced pressure. Reduced pressure is supplied to the canister via a reduced-pressure delivery conduit that includes a moisture processing device and a hydrophobic filter. The moisture processing device condenses moisture from the air to prevent condensation from occluding the hydrophobic filter. The moisture processing devices includes an expanded volume and one or more liquid-impermeable, vapor-permeable membranes. The liquid-impermeable, vapor-permeable membrane allows vapor to egress the moisture processing device. Other systems, methods, and devices are presented.

Some embodiments are directed to a system 10 for the application of topical negative pressure therapy to a site 18 on the body of a mammal. Some embodiments of the system 10 comprise a piston 22 and cylinder 24 device 12 having a self-contained power source for the generation of a reduced pressure and for aspirating the site 18. Some embodiments of the system 10 comprise a dressing 14 sealably surrounding the site 18 that can be operably connected to the device 12 by a conduit means 16 to apply the reduced pressure to the site 18.

The present invention is directed to improved methods, devices, and systems for eye surgery. In some embodiments, the invention may provide new and/or improved devices, systems, and methods for detecting surgical fluids in a fluidics cassette, particularly cassettes which are used to couple an eye treatment probe to an eye treatment console. Rather than relying on internal reflection by a gas-liquid interface, the fluid detection techniques described herein may make use of the changes in propagation of light through a portion of the holding tank when the portion varies between empty and full. Other aspects of the invention may provide devices, systems, and methods for producing different types of fluidics cassette using a single cassette body type.

A medical sampling device is disclosed for use with a medical device having a suction channel and a suction connector in fluid communication with said suction channel. The sampling device includes a suction inlet for connection to the suction connector, a suction outlet for connection to a vacuum source, a sampling inlet and outlet for connection to a sample container, and a valve including a valve member having first and second chambers and being rotatable between first and second positions. The first chamber in the first position establishes fluid communication between the suction inlet and the sampling inlet. The second chamber in the first position establishes fluid communication between the sampling outlet and the suction outlet. One of the first and the second chambers in the second position establish fluid communication between the suction inlet and the suction outlet.

An aspiration thrombectomy system for use with a vacuum source and an aspiration catheter includes a connection tubing configured to selectively connect the aspiration catheter to the vacuum source via a controllable vacuum valve. A distal pressures sensor is configured to detect pressure at the distal end within the connection tubing. An automatic controller may operate the vacuum valve to generate fluid pressure change in the connection tubing, and detect pressure profiles in the connection tubing correlated with the generated pressure changes via the distal pressure sensor. The automatic controller may determine one or more system states in the aspiration catheter or connection tubing based on the detected pressure profiles, and may operate the vacuum valve based on the determination of system state.

Examples relate to devices, systems, and methods for collecting and measuring discharged urine. A urine collection system includes a urine collection device configured to collect urine discharged from a user and a urine collection container in fluid communication with the urine collection device and sized and dimensioned to receive the urine discharged from the user. The urine collection system also includes a flow meter having a communication interface and positioned between the urine collection container and the urine collection device. The flow meter is configured to detect a flow property of the urine at least related to a volume of the urine entering the urine collection container and the communication interface is configured to wirelessly communicate to a computing device at least one of the detected flow property or the volume of the urine including the volume of the urine discharged from the user entering the urine collection container.
