There is provided a device for automatic synchronized injection and aspiration of fluids comprising: a first linear actuator; a second linear actuator; a first coupling mechanism attached at a distal end portion of the first linear actuator, the first coupling mechanism arranged for detachable coupling to a first plunger of a first syringe; a second coupling mechanism attached at a distal end portion of the second linear actuator, the second coupling mechanism arranged for detachable coupling to a second plunger of a second syringe; and a synchronization mechanism mechanically coupled to the first and second linear actuators, the mechanism arranged so that insertion of the first plunger further into a first barrel of the first syringe is synchronized with extraction of the second plunger from a second barrel of the second syringe, thereby injection from the first syringe is synchronized with aspiration into the second syringe.

A sound suppression system for reducing or eliminating sound produced by the operation of a breast vacuum pump includes a sound suppressing muffler assembly having an air entry port adapted to communicate with an air outlet port of a vacuum pump or other air flow generating device. The sound suppressing muffler assembly also includes a muffler housing defining an internal space communicating with the air entry port, and an opening in the housing leading to atmosphere. The muffler housing has a tortuous air path in the muffler housing. In one embodiment, sound absorbing porous foam structure is disposed in the tortuous air path. The at least one sound absorbing porous structure absorbs sound energy from the air as the air moves through the at least one air path toward the opening in the muffler housing. In further embodiments, a tortuous air path is provided between an air entry port and an opening to atmosphere in the muffler assembly.

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.

Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. Maintenance and control of the sub atmospheric pressure exerted may be provided by such devices while minimizing discomfort to the user. The devices may be configured to be worn inconspicuously underneath clothing.

An ophthalmic surgical device includes an irrigation line for irrigation fluid flowing from an irrigation container to a handpiece and an aspiration line for aspiration fluid flowing from the handpiece to a collecting container. A first volumetric flow rate determination apparatus is arranged upstream of the handpiece and determines a first volumetric flow rate in the irrigation line. A second volumetric flow rate determination apparatus is arranged downstream of the handpiece and determines a second volumetric flow rate in the aspiration line. An occlusion determination apparatus acquires a time curve of the first volumetric flow rate and a time curve of the second volumetric flow rate, to compare with stored time curves of the first volumetric flow rate for different occlusion states and stored time curves of the second volumetric flow rate for different occlusion states, and to determine a current occlusion state in the aspiration line therefrom.

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.

Exemplary systems for small volume collection for a breastpump system are provided. The systems allow breast milk to flow directly from the breastshield to the collection container without leaving the control volume. A valve is present outside of the milk flow path that does not contact breast milk prior to the milk reaching a collection vessel.

Embodiments of the present invention disclose a device for removing adipose tissue with a needle(s), comprising a needle hub that comprises at least one needle that contains between 1-1000 holes around the circumference of the needle barrel which allows passage of adipose tissue and other lipoaspirate, and an adipose tissue collection and purification device comprising a plurality of self-contained syringes wherein each of the syringes comprises an inner syringe included within an outer syringe and wherein a filter is attached inside the outer syringe barrel, the filter having a mesh pore size between 30 micro meters and 1000 micro meters, the device being attached to a needle hub. The present invention further provides a system for closed adipose tissue harvesting, purification, and grafting, comprising an adipose tissue removal component, a collection and purification component, and a grafting component. Methods of using the devices or system are also disclosed.

Embodiments of the present invention disclose a device for removing adipose tissue, comprising a self-contained syringe device comprising an inner syringe included within an outer syringe and wherein a filter is attached inside the outer syringe barrel; wherein the filter comprises a filter material that prevents premature filter collapse where the filter material is optionally coated to increase stiffness, and wherein liposuctioned adipose tissue is collected and purified inside the syringes. Methods of using the devices or system are also disclosed.
