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).

Systems and methods for wound drain management. Certain embodiments include an infection indicator and/or a coupling device configured to such that a wound drainage container can rotate in relation to a mounting device.

Apparatuses and methods for improving airway patency are provided. A medial surface of the patient's tongue is constrained with a tongue constraint of an oral device placed in the oral cavity to generate a clear region between the medial surface and the hard palate. The clear region is in fluid communication with the soft palate. The tongue constraint has superior surface and inferior surfaces configured to generate the clear region. Negative pressure is applied within the oral cavity to hold the soft palate in a position in which the airway is at least partially open. The negative pressure is applied through one or more ports of the oral device. The one or more ports remain unobstructed by the tongue when the negative pressure is applied. The applied negative pressure causes the soft palate and tongue form a seal whereby the patient's airway is substantially fluidly isolated from the clear region.

A manifold apparatus and method of opening a valve in a medical/surgical waste collection unit. The manifold includes a base at a proximal end with the base defining an opening off center from an axis of the manifold. The manifold further includes two arcuately spaced tabs, each subtending arcs having different arcuate lengths. The manifold is positioned such that the tabs mate with at least two slots of a lock ring of the waste collection unit so as to cause the opening of the manifold to be, upon insertion into a bore of the waste collection unit, in a specific rotational alignment in the bore. The manifold is rotated within the bore to cause a valve disk to move between a first position in which the valve disk blocks fluid flow through the receiver and a second position in which the valve disk allows fluid flow through the receiver.

A tissue collection and processing system for collecting bone fragments and tissue aspirated from a bone. The tissue collection and processing system includes a collection vessel, a collection vessel cap, a processing cover, a first tubing and a fluid withdrawal mechanism. The collection vessel has an opening formed therein to receive bone fragments and tissue aspirated from the bone. The collection vessel cap is capable of engaging the collection vessel to substantially seal the opening. The collection vessel cap or the collection vessel has a first port. The processing cover has an upper surface and a lower surface. The processing cover has a connection port and a bore. The connection port is proximate the upper surface. The bore is fluidly connected to the connection port and extends toward the lower surface. The processing cover has a density that is less than a density of fluid in the aspirated bone fragments and tissue. The fluid withdrawal mechanism is fluidly connected to the connection port with the first tubing to withdraw the fluid from the collection vessel. As fluid is withdrawn from the collection vessel, the processing cover is slidable in the collection vessel.

A medical system includes a medical instrument including an irrigation and aspiration channel to carry irrigation fluid to, and remove aspirated matter from, a distal end of the medical instrument, a reservoir to store the irrigation fluid, a receptacle to collect the aspirated matter, and a vane pump including a pump housing having an inner surface around a pumping chamber, the pump housing including irrigation inlet and outlet ports coupled to the pumping chamber and respectively connected to the reservoir and the irrigation channel, and aspiration inlet and outlet ports coupled to the pumping chamber and respectively connected to the aspiration channel and the receptacle, and wherein the vane pump is configured to simultaneously pump via the pumping chamber, at substantially the same flow rate, the irrigation fluid from the reservoir to the distal end and the aspirated matter from the distal end to the receptacle.

Methods and devices for treating lipoaspirate for use in fat grafting procedures are provided and generally include a canister for containing lipoaspirate, a separation mechanism structured to separate both oils and other materials from cellular components of lipoaspirate contained in the canister. The separation mechanism includes filters having different filtering capacities, for example, different pore sizes.

The present disclosure provides devices and methods for harvesting and processing tissue from patients for grafting. The devices can include a tissue collection chamber for ascetically collecting, processing, and/or re-implanting adipose tissue.

A medical/surgical waste collection rover includes a first waste container disposed on a portable cart and receiving waste under the influence of a vacuum. A fluid measuring system includes a float element disposed within the first waste container, and a controller causing liquid in a reservoir disposed on the cart to prefill the first waste container and subject the float element to an initial lifting to a zero point level. The fluid measuring system determines a volume of contents within the first waste container based on a position of the float element relative to the zero point level. The fluid measuring system may include a sensor rod extending through the first waste container and a second waste container disposed on the cart and separated from the first waste container by a transfer valve. Methods of estimating the volume of liquid and/or medical/surgical waste within the waste container are also provided.

The invention relates to a suction bag emptying device (13) comprising a container (15) with a lid for a suction bag to be placed into the container. The container (15) has a discharge point (17) for removal of the contents of the suction bag. The emptying device (13) is provided with a holder for suspending a suction bag with a lid from the holder by the lid, and a jacket (24) for lateral support of the suction bag. The lid (14) of the emptying device (13) is provided with means for puncturing the lid (4) of the suction bag (3) and for supplying pressurized liquid or gas into the suction bag (3). The invention also relates to an assembly comprising at least one suction bag (3) and a suction bag emptying device (13), and to a method for emptying the suction bag (3).
