System for treating embolism and associated devices and methods
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.
Arrangements for sterile fat harvesting
According to an example aspect of the present invention, there is provided a sterile connector for fat harvesting, comprising a body configured to be at least partially inserted into a receptive syringe chamber. The body comprises an external interface end for facing the ambient space and an internal interface end for insertion into the syringe chamber. The connector further comprises a fat input conduit extending through the body. The fat input conduit comprises a coupling for a harvesting tube at the external interface end of the body and a feed port at the internal interface end of the body for feeding the harvested fat into the syringe chamber. The connecter further comprises an air output conduit extending through the body. The air output conduit comprises a coupling for a suction tube at the external interface end of the body and a suction port at the internal interface end of the body for providing a partial vacuum into the syringe chamber.

NEGATIVE PRESSURE PUMPS AND RELATED METHODS
Devices and systems disclosed herein may include a negative pressure pump that includes a reservoir defining a lumen and a longitudinal axis, a piston, and a drive assembly comprising a spring. Motion of the spring may move the piston along the longitudinal axis of the reservoir to create a negative pressure within the reservoir. Methods of manufacturing a negative pressure pump and using a negative pressure pump to remove fluid from a target site are also described.
Adipose tissue transplantatioin device
An adipose or fat tissue transplantation device is disclosed. The device employs a cylindrical vessel for housing a conventional piston operated syringe. A handle is pivotally attached to the cylindrical vessel with a proximal end secured to a puller positioned to engage steps attached to the piston. A distal end of the handle provides a thumb operated lever for advancing the piston a predetermined distance upon depressing the handle to move the piston. The handle includes a link arm of a length sized to move the puller upon engaging a step a predetermined distance. A spring is coupled to the link arm to maintain the distal end of the handle in a normally raised position. In a preferred embodiment, the link arm and steps are constructed and arranged to advance the piston to cause a predetermine dispensing of tissue for each handle depression.
REDUCED PRESSURE THERAPY DEVICES
Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.
BONE FRAGMENT AND TISSUE PROCESSING SYSTEM
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.
