A bone marrow aspiration device may include a housing having a proximal end and a distal end; a cannula, insertable into a tissue, extending from the distal end; a ratcheting mechanism coupled to the housing; a reservoir configured to receive a fluid; an actuator operatively coupled to the ratcheting mechanism and to a distal surface of the bone marrow aspiration device such that user-actuation of the actuator actuates the ratcheting mechanism to draw fluid through the cannula, into the housing, and into the reservoir, and retracts the cannula relative to the distal surface.

A fat harvesting system and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self-contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.

Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a distal portion of a catheter proximate to the clot material within the blood vessel. The method can further include coupling a pressure source to the catheter via a tubing subsystem including a valve or other fluid control device and, while the valve is closed, activating the pressure source to charge a vacuum. The valve can then be opened to apply the vacuum to the catheter to thereby aspirate at least a portion of the clot material from the blood vessel and into the catheter.

Systems, devices and methods for use in liposuction and infusion medical procedures including handheld devices, micro-cannulas, curved cannulas vacuum pressure changing features.

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 suction device includes a negative pressure generator, a connector and a mask; the negative pressure generator comprises a housing and a piston rod, wherein the housing is internally provided with a cavity, an upper end of the housing is provided with an avoidance hole communicated with the cavity, and a lower end thereof is provided with an opening communicated with the cavity; the piston rod comprises a push-pull rod and a piston sleeved on the push-pull rod, an upper end of the push-pull rod runs through the avoidance hole, and the piston is movably and hermetically connected to an inner side wall of the housing by means of a sealing ring; an upper side of the mask is provided with a through first connecting cylinder, and a lower side thereof is provided with a flexible annular pad configured to fit with the face.

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.
