The present disclosure relates to a devices and methods to control suction during medical procedures, and more particularly to medical suction devices, systems, and methods for controlling suction using the portable suction devices/systems during endoscopic procedures. For example, the present disclosure includes a portable suction device in fluid communication with an endoscope system, the portable suction device including: a suction regulator device releasably coupled to and in communication with at least one suction tube of the endoscope system, the at least one suction tube in fluid communication with an endoscope of the endoscope system and a suction source of the endoscope system, wherein the suction regulator device is actuatable to at least one of increase or decrease a suction force within the at least one suction tube.

A treatment device for treatment of overactive bladder conditions operates to suction to grasp and conform a mucosal tissue of the bladder wall to a portion of the tissue treatment device, and deliver energy to non-superficial target tissue at a substantially uniform depth from the mucosal tissue. The tissue treatment device incorporates multiple instruments for different functions needed to treat overactive bladder conditions. The tissue treatment device provides simplified interfaces and mechanisms for operating each of the multiple instruments in a controlled manner. Further, the tissue treatment device is configured to have a low and smooth profile that permits the tissue treatment device to be used without a tubular sheath.

An instrument system for treating 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.

Vitreoretinal instruments and methods related thereto are disclosed herein. The disclosure describes various example vitreoretinal instruments having various aspirating port configurations. A vitreoretinal instrument may include a handle and a cannula coupled to the handle. The cannula may include a straight portion and a curved portion. The curved portion may be configurable between a straight configuration and a curved configuration. The curved configuration may include a first curved portion having a curvature defined by a first radius. The curved configuration may include a second curved portion having a curvature defined by a second radius different from the first radius. The curved portion may further include one or more ports formed in the curved portion.

A system and method for automatically removing by suction urine voided by a female. The system includes an integrated external catheter and suction regulator unit. The external catheter is applied at the female's urethra opening to receive urine voided by the female. The suction regulator is connected to a receptacle for collecting the urine and is operative to regulate suction applied to the canister from a hospitals' suction line to a regulated value which is applied the external female catheter, whereupon urine from the external female catheter is carried by the regulated suction through the suction regulator and into the receptacle. The external catheter includes an internal suction tube and an external removable and replaceable liquid permeable cover located on the internal suction tube. The external catheter is malleable so that it can be conformed to the anatomy of the female.

An aspiration control device can have an aspiration control valve and a switch, button, slider, trigger, grip, lever, rotating wheel, rotating valve, handle or other interface for resizing the aspiration control valve. The aspiration control interface can be conveniently positioned and configured to be manipulated while simultaneously stabilizing a catheter and/or retracting an elongated member. The aspiration control device can be integrated with a hemostasis valve, integrated with a wire gripping device, and/or attached to an inlet, outlet, hose, pump, or syringe in series with an aspiration flow path.

A surgical irrigation and suction control apparatus connecting to an irrigation device and a suction device includes a flexible cannula, a grip, a first tube, a second tube, an irrigation control unit and a suction control unit. The grip is connected to the flexible cannula. The irrigation control unit includes an irrigation switch and an irrigation tube. The irrigation tube is flexible and is connected between the second tube and the irrigation device. The irrigation switch is disposed on the grip and is actuated to change a diameter of the irrigation tube. The suction control unit includes a suction switch and a suction tube. The suction tube is flexible and is connected between the second tube and the suction device. The suction switch is disposed on the grip and is actuated to change a diameter of the suction tube.

A saliva ejector device comprises a handle having a passageway in fluid communication between a vacuum device and a saliva ejector. The saliva ejector device comprises an automatic switching mechanism comprising a button that is switchable between open and closed positions to allow or restrict restricts airflow. The button can be automatically actuatable, via a compliant device in the handle, when an individual places the handle in the cradle or removes the handle from the cradle. The compliant device can be a tube that allows or restricts airflow about the passageway, or a spring in the passageway that actuates the button. A saliva ejector device comprises a handle having an upper housing rotatably coupled to a lower housing to selectively switch the handle between open and closed positions to allow or restrict airflow about the handle. A handle adapter has a spherical body for an individual to cup or hold to improve ergonomics. Associated systems and methods are provided.

Provided is a medical device for clearing an obstruction from a surgical instrument or surgical site, the device comprising: a first hollow member configured to allow air or inert gas passage; a second hollow member having a distal end and a proximal end, the proximal end configured to be connectable to a vacuum or suction source; a housing member configured to receive both the first hollow member and the second hollow member; and a push button operably connected to the housing member; and an inflation bulb configured to be attachable to the housing member, wherein the push button is configured to disengage the first hollow member and occlude the second hollow member when depressed by a force, and/or wherein the push button and the inflation bulb are configured to be operable by one hand of an operator.
