A surgical handpiece for removing tissue includes a housing defining a cavity therein, the housing having a proximal hub connector disposed at a distal end thereof. An end effector assembly is operably supported by the proximal hub connector and includes an outer shaft supporting a cutting shaft configured to remove tissue upon activation thereof via translation or rotation. A fluid pump is disposed within the cavity of the housing and is configured to evacuate fluid from the cutting shaft upon activation thereof. A motor is disposed within the cavity of the housing and includes a power coupler operably coupled to both the cutting shaft and the fluid pump for suppling power thereto.

Techniques for blockage removal are provided, which may provide immediate and effective aid to a choking victim. A blockage removal device may comprise a mouthpiece disposed on an inlet. The inlet may be coupled to a chamber configured to hold a vacuum generated by a vacuum pump. A vacuum gauge may display information to a user, who may open or close a valve to provide or remove a vacuum to attempt to remove a blockage.

Embodiments are directed towards fluid collection assemblies that include at least one length adjusting feature, fluid collection assemblies including the same, and methods of using the same. An example fluid collection assembly includes a fluid impermeable barrier. The fluid impermeable barrier includes a distal region, at least one distal end region spaced from the distal region, and at least one intermediate portion extending from the distal region to the distal region. The fluid impermeable barrier also defines at least one length adjusting feature (“LAF”) extending from the distal end region to the distal region. The LAF allows the length of the fluid collection assembly to change. The ability of the fluid collection assembly to change the length thereof allows a penis of a patient to be disposed in preferential locations within the fluid collection assembly.

Ureteral or bladder catheters are provided, including (a) a proximal portion; and (b) a distal portion, the distal portion including a retention portion that includes one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter. Systems, kits and methods for inducing negative pressure to increase renal function also are provided.

A device for supplying and/or aspirating a fluid substance to or from a human or animal body is provided, which device has a drive unit with a drive, an attachment part, and coupling element. The attachment part has a peristaltic pump unit with a pump head having roller elements which are movable freely and independently of one another and serve for rolling on a hose. The coupling element serves to transmit a movement from the drive to the pump head. The pump head has a decoupled state in which the roller elements apply no or a comparatively low mechanical pressure to the hose, and a coupled state in which the roller elements are pressed by the coupling element against the hose with a comparatively high mechanical pressure.

A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer, measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer, comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.

An apparatus for applying a vacuum during a surgical procedure can include a vacuum pump assembly having a port, a first housing, a second housing, a first silencer or tubular magnet and a second silencer. The first housing can define a first cavity receiving the vacuum pump assembly therein. A portion of the first housing can be formed by a portion of the port. The second housing can define a second cavity receiving the first housing therein. A portion of the second housing can be formed by a second portion of the port. The first silencer or tubular magnet can be coupled to the first housing and can have a longitudinal extent along a longitudinal axis. The first silencer or tubular magnet can extend from the first housing within the second cavity. The second silencer can be coupled to the second housing and can have a longitudinal extent along a longitudinal axis. The second silencer can extend from the second housing within second cavity.

A fluid pump system having a first fluid pump for pumping fluid from a source to a surgical site and a second fluid pump for removing fluid from the surgical site at a first predetermined rate, wherein said fluid pump system intermittently operates in conjunction with a surgical tool which, when operational, removes fluid from the surgical site at a second predetermined rate greater than said first predetermined rate, the improvement including a sensor for sensing a predetermined parameter of the surgical tool and providing an output signal indicating that the surgical tool is operating; and an actuating means responsive to said output signal to actuate said second fluid pump to remove fluid from the surgical site at second predetermined rate.

An apparatus for treating urinary retention of a patient by discharging urine from the urinary bladder. The apparatus comprises an expandable member, adapted to be implanted inside the urinary bladder of a patient, for discharging urine from the urinary bladder as a result of its expansion in volume, an implantable control device for controlling the volume of the expandable member, and an external energy transmission device for wireless transmission of energy from the outside of the patient's body to the inside of the patient's body configured to operate the expandable member and other energy consuming implantable parts of the apparatus.

A device and a method for creating and/or maintaining an obstruction free upper respiratory passages. The device is configured to fit under the chin of a subject adjacent to the subject's neck at an external location corresponding approximately with the subject's soft tissue associated with the neck's anterior triangle. The device is capable of exerting negative pressure on the surface of a subject's neck, displacing the soft tissue forward and enlarging the airway.
