An apparatus including a frame, where the frame includes a user handle, a motor receiving area, and a first aperture through the frame into the motor receiving area, where the motor receiving area is configured to removably receive a cannulated motor assembly therein; and a first seal located proximate the first aperture through the frame, where the first seal is configured to form a seal between the cannulated motor assembly and the frame when the cannulated motor assembly is in the motor receiving area.

An anti-clog suction tip apparatus includes a suction tip having a suction opening and an interior defining a suction channel. An ejection wire channel extends to a wire exit opening into the suction channel that is located proximate the suction opening. An ejection wire including a ball tip at an end thereof occupies the ejection wire channel and is transitionable between a retracted configuration and an advanced configuration such that, in the retracted configuration, the ejection wire including the ball tip is retained within the ejection wire channel and does not obstruct suctioning of debris through the suction channel; and in the advanced configuration, the ball tip of the ejection wire does not extend more than three millimeters beyond the suction opening.

A vacuum assisted suction and irrigation system includes a suction and irrigation wand, an irrigation fluid supply, a vacuum source, and a fluid pump. The vacuum source is connected to a suction valve of the suction and irrigation wand to provide suction within the suction and irrigation wand. The irrigation fluid supply is connected to the suction and irrigation wand via the fluid pump to supply pressurized irrigation fluid to the suction and irrigation wand. The vacuum source is connected to the fluid pump to pressurize the irrigation fluid being delivered to the suction and irrigation wand.

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.

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.

A method for improving a flow condition through a catheter includes coupling a distal end of a first conduit of a tubing set to an aspiration lumen of an aspiration catheter, coupling a proximal end of the first conduit to a vacuum source, coupling a distal end of a second conduit of the tubing set to a supply lumen of the aspiration catheter, coupling a proximal end of the second conduit to a first fluid source, inserting a distal end of a sheath within the vasculature of a subject, placing the aspiration catheter through the sheath and advancing the aspiration catheter such that an open distal end of the aspiration lumen of the aspiration catheter is distal to a distal end of the sheath and is in proximity to a thrombus within a blood vessel of a subject, coupling an extension conduit in fluid communication with a lumen of the sheath to a second fluid source, and activating a pump such that pressurized fluid from the first fluid source is applied to the supply lumen of the aspiration catheter, wherein when insufficient flowable material is present adjacent the open distal end of the aspiration lumen, fluid from the second fluid source is caused to flow through the lumen of the sheath.

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.

A system for extracting lens material from an eye including an instrument having a first aspiration pump driven by a drive mechanism having a motor, and an elongate member sized and configured to extend through an anterior chamber to a capsular bag of the eye. The elongate member configured to be oscillated by the drive mechanism includes an inner lumen fluidly coupled to the first aspiration pump and defining at least a portion of an aspiration waste line, and an open distal end having a distal cutting tip. The system can further include a fluid system remote from the surgical instrument including a second aspiration pump and a fluid line configured to deliver background aspiration from the second aspiration pump to the inner lumen of the elongate member to aspirate the lens material from the eye towards the inner lumen. Related devices, systems, and methods are also provided.

An instrument system for treating a sinus of a subject includes an instrument including a base configured to be gripped by an operator, and an elongate probe including a probe proximal end coupled with the base and extending to a probe distal end. The probe includes an aspiration lumen terminating at an inlet port proximate the probe distal end, and a delivery lumen terminating at an outlet port proximate the probe distal end. The instrument also includes a waveguide on the probe and having a light emitting end proximate the probe distal end.

A method for capturing dislodged vegetative growth during a surgical procedure is provided. The method includes maneuvering, into a circulatory system, a first cannula having a distal end and an opposing proximal end, such that the first cannula is positioned to capture the vegetative growth en bloc. A second cannula is positioned in fluid communication with the first cannula, such that a distal end of the second cannula is situated in spaced relation to the distal end of the first cannula. A suction force is provided through the distal end of the first cannula so as to capture the vegetative growth. Fluid removed by the suction force is reinfused through the distal end of the second cannula. Subsequent to becoming dislodged, the vegetative growth is captured by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.
