The disclosure provides for an isovolumetric pump system for the removal of a thrombus and a method of use thereof. The isovolumetric pump system includes at least one inflow container connected to an output of the treatment region, at least one outflow container connected to an input of the treatment region, and a drawbar connecting the inflow container and the outflow container. As the drawbar is drawn back, the same quantity of fluid is drawn from the treatment region into the inflow container and injected into the treatment region from the outflow container.

A medical device is adapted for use in assisting with mechanical thrombectomy. The medical device may include a housing that is adapted to be held within a user's hand and a pump that is secured within the housing. A fluid inlet is adapted to receive fluid that is pulled towards the pump and is fluidly coupled with the pump. A fluid outlet is adapted to expel fluid away from the pump and is fluidly coupled with the pump. As the pump is operated by the user, fluid is alternatively pulled into the fluid inlet and expelled through the fluid outlet. In some cases, the fluid may be blood or other bodily fluids.

A suction device configured to simultaneously draw in fluid and expel fluid. The suction device may comprise a barrel defining a cavity and extending from a first end to a second end. A first fluid inlet may be adjacent the first end of the barrel and a second fluid inlet adjacent the second end of the barrel and a first fluid outlet may be adjacent the first end of the barrel and a second fluid outlet adjacent the second end of the barrel. A plunger may be slideably disposed within the cavity of the barrel with a handle assembly operably coupled thereto. A actuation of the handle assembly may be configured to move the plunger within the cavity between the first end and the second end of the barrel.

A fluid management system for an ophthalmic surgical system includes an irrigation system and an aspiration system. The irrigation system carries fluid toward a handpiece and includes an irrigation pump or a plurality of pumps. The aspiration system carries fluid away from the handpiece and includes an aspiration pump or the plurality of pumps. The pumps include at least one magnetic pump configured to move the fluid. The magnetic pump includes a plug system and a magnetic field system. The plug system includes one or more plugs disposed within a housing, where each plug comprises a magnetic material. The magnetic field system generates a magnetic field to move one or more of the plugs in order to move the fluid in a pumping direction.

An airway assist device and methods of making and using an airway assist device to assist in opening an airway or removing fluid or material obstructing an airway of a subject.

A fat suction and graft syringe includes a negative pressure adjustment mechanism. The negative pressure state in a barrel can be maintained during a procedure only by pulling and releasing a plunger, and only by slightly rotating the plunger. The plunger can be pushed inside the barrel without being constrained by a multi-level holding plate and a single-surface rotation clip, whereby the syringe has enhanced convenience in the use and production thereof so that many practitioners accustomed to using a normal syringe can easily use the syringe without separately learning how to manipulate the syringe.

A system for aspirating thrombus that includes an aspiration catheter, a tubing set connected to the aspiration catheter, a pressurization element configured to couple to the tubing set and further configured to pressurize fluid from a first fluid source or allow pressurized fluid from the first fluid source to be transferred through a supply lumen of the aspiration catheter, and a sheath through which the aspiration catheter can be advanced.

The present disclosure relates to wound bandages. More specifically, the present disclosure describes a vacuum sealed bandage having a film layer that is manipulable into a wound by way of negative pressure imparted by a removable medical syringe. The vacuum sealed bandage of the present disclosure does not have a vacuum pump, does not constantly apply negative pressure to the wound through an electro-mechanical device or vacuum pump, and/or does not have chords or tubes positioned to opposite sides of the film layer or extending from one side of the film layer to another side of a film layer where the chord or tube is positioned between the film and the wound.

Inline pumps with rear attachable syringes include a pump and a syringe with each designed so that the pump syringe system may be easily coupled and decoupled in the field. An end mount block on the pump has a slot shaped to accept a similarly shaped plunger button and plunger rod on the syringe. A user aligns the plunger button of the syringe next to the slot on the mount block of the pump, and slides the plunger button and rod into the inner cavity of the pump. Both the pump and the syringe have threaded couplers which securely couple the pump to the syringe by rotating the couplers with respect to each other.

A device for clearing an obstructed airway of a subject, including an airway interface configured to be positioned over a mouth and/or nose of the subject, a pump in fluid communication with the airway interface and configured to generate suction at the airway interface when activated, and a sleeve surrounding the pump, where the device is configured to activate the pump to generate the suction when the airway interface is pushed against the mouth and/or nose of the subject by pushing on the sleeve, where the device is configured to be held and activated with one hand.
