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.

Various embodiments of the systems, methods and devices are provided for breaking up calcified lesions in an anatomical conduit More specifically, an electrical arc is generated between two spaced-apart electrodes disposed within a fluid-filled balloon, creating a subsonic pressure wave. In some embodiments, the electrodes comprise a plurality of points that allow the electrical arc to form at any one of the plurality of points to, among other things, extend the electrode life.

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.

A catheter system includes a shaft main body including an elongated hollow outer tube and an inner tube accommodated in the inside of the elongated hollow outer tube. The hollow inside of the inner tube is suctioned from the proximal end side thereof. The outer tube has an opening formed in a circumferential surface thereof and an attaching portion provided therein on the distal end side with respect to the opening. The inner tube can move in an axial direction with respect to the outer tube, and at least a distal end side end portion thereof can move back and forth between a proximal end side position with respect to the opening and the attaching portion. The inner tube has a cutting unit provided in the hollow inside of the distal end side end portion thereof and is capable of attaching to the attaching portion

A clot capture module can include a housing, a chamber inside the housing, a window, and a filter. The window permits visual inspection of a clot inside the chamber. The clot can access the chamber via an incoming flow path configured to direct blood from an aspiration catheter to an upstream surface of the filter. An aspiration control valve can block the flow of incoming aspirated blood until actuated to permit inflow of aspirated blood. An outgoing flow path can direct blood from a downstream surface of the filter to a remote vacuum canister.
