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.

An apparatus includes a cannula, a suction port, and a guidewire channel. The cannula includes a proximal end, a distal end, and a first lumen. The suction port is configured to communicate suction to the distal end of the cannula via the first lumen. The guidewire channel includes an open proximal end, an open distal end, and a second lumen extending from the open proximal end to the open distal end. The guidewire channel is securely attached to the cannula such that the second lumen is laterally offset from the first lumen. The guidewire channel is configured to slidably receive a guidewire within the second lumen. The guidewire channel is formed of an elastic material such that the guidewire channel is configured to resiliently expand the second lumen outwardly to an expanded state in response to slidably receiving a guidewire therein.

The present disclosure includes methods, apparatuses, and systems for aspirating the airway of a patient. The apparatus includes a main body having a pump and a storage cannister housing coupled to the main body and containing a storage container that is at least partially collapsible. In some configurations, the main body can include a pressure sensor, a controller in communication with the pressure sensor, and having a processor, a memory, and a power source in communication with the controller. The storage cannister housing can include a first end coupled to the main body, and a second end having a weighted portion and configured to be coupled to the first end to permit free rotation, such that the second end gravitationally rotates.

A cleaning catheter insertable into a ventilation tube and an input module are provided, the input module coupled to the cleaning catheter and including (i) an inflation module, including an inflation chamber and a one-way air inlet valve; (ii) a flow regulator operable to assume first and second fluid-control states; and (iii) a mechanical user control element operable (a) to mechanically and non-electrically set the fluid-control states, (b) to assume first and second configurations, and (c) to mechanically and non-electrically increase pressure in an interior of an inflation chamber of the cleaning catheter during a transition of the mechanical user control element from the first configuration to the second configuration. The one-way air inlet valve is arranged to allow air to flow into the inflation chamber during a transition of the mechanical user control element from the second configuration to the first configuration.

A handpiece for a surgical instrument having a valve position sensing circuit arranged to detect the position of a valve arranged to control the flow of fluid through the suction lumen of the instrument. The distal end of the handpiece is arranged to couple to a cutting accessory. The handpiece comprises: a housing; a suction lumen within the housing extending from the distal end of the handpiece to a proximal end of the handpiece; a valve arranged to control the flow of fluid through the suction lumen; and a valve position sensing circuit arranged to detect a position of the valve. The valve position sensing circuit can be used to alert a surgeon if the valve is closed when it would be preferable for it to be open. For example, if the motor is overheating, the in-joint temperature is too high, or the RF component is activated.

A surgical drain tray assembly includes a fluid impermeable first layer and a porous second layer positioned on the fluid impermeable first layer. The fluid impermeable first layer includes a drain outlet, a basin, and a sloping surface angled toward the basin, the drain outlet being positioned within the basin. The porous second layer may be formed of a foam material and includes a top work surface. Fluids spilled onto the work surface pass through the porous second layer to the fluid impermeable first layer. The sloping surface of the fluid impermeable first layer conveys the fluids toward the basin for draining through the drainage outlet.

In one aspect, an implant removal device for removal of ruptured silicone breast implants includes a hollow container having a middle portion disposed between a first end and a second end. The device also has a connector port coupled to the second end that is coupled to a suction device during use. The device also includes a nozzle coupled to the first end that is configured for placement against an incision of a patient for removing a ruptured breast implant from the patient. The middle portion of the hollow container defines one or more vent holes extending between an interior and exterior container surface with the one or more vent holes configured to reduce negative pressure within the hollow container when the suction device is activated during the removal process.

Kidney stone removal system is disclosed having components including a handle mechanism, a nozzle tip, and a guiding device. The handle mechanism employs a trigger that enables control of irrigation and vacuum/suction. Depression of a trigger in the trigger mechanism conveys status of vacuum/suction and irrigation to a user by providing increased resistance at different points of depression. When the trigger is in a home (undepressed) position, irrigation and vacuum/suction are turned off. When the trigger is in a fully depressed position, irrigation and vacuum/suction are turned on. When the trigger is in an intermediate position, irrigation may be turned on, while vacuum/suction remains turned off. The nozzle includes one or more irrigation ports positioned at a distal end of the nozzle and having an irrigation port departure angle of 30 to 60 degrees for directing irrigation fluid forward and laterally from the distal end of the nozzle. The guiding device is configured to be removably positioned in the nozzle for receiving a debris fragmentizing device, such as a laser device. The guiding device is configured to prevent an unintended movement of the fragmentizing device when the fragmentizing device is positioned in the nozzle while allowing fluid and debris to flow past the fragmentizing device and through a vacuum tube.

Embodiments of the invention are directed to a medical device with a handpiece that provides enhanced comfort of use, maneuverability, and for a variety of hand-held options to the user. Embodiments of the invention include handpieces that include a grip panel comprised of a friction-enhancing material to facilitate gripping of the handpiece by an operator. In addition, embodiments of the invention include handpieces having a generally symmetrical configuration in order to facilitate grasping by an operator's left or right hand.
