Abstract: An endoscope includes a shaft having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft, and an image sensor is carried on the distal end of the shaft. A channel extends through at least a distal shaft portion and has a channel diameter, and a section of the channel is re-configurable between a constricted shape and a non-constricted shape to accommodate tools introduced therethrough. The combined diagonal dimension and channel diameter is usually greater than the outer shaft diameter. The image sensor may be connected to a connector on the housing by a first slack flex circuit and a lights source on the shaft may be connected to a connector on the housing by a second slack flex circuit.

Abstract: A surgical fluid management system includes a console and a cassette for delivering fluids to a surgical site. The console has a pump rotor and a pressure-sensing membrane. The cassette has a cassette housing, a flexible fluid delivery tube in the housing. The flexible fluid delivery tube has a lumen configured to interface with the pump rotor and to deliver a flow of fluid from a fluid source as the rotor is rotated. A pressure-transmitting membrane is located in a wall of the cassette housing and in fluid communication with said fluid delivery lumen. The pressure-transmitting membrane flexes outwardly in response to a positive pressure in the lumen and flexes inwardly in response to a negative pressure in the lumen. The pressure-transmitting membrane detachably adheres to or presses against the pressure-sensing membrane to cause the pressure-sensing membrane to move in response to pressure changes in the flexible fluid delivery tube.

Abstract: Medical devices and methods for treating and occluding a female patient's fallopian tubes to provide permanent birth control or sterilization.

Abstract: An endoscope includes a shaft assembly having proximal and distal ends and a longitudinal axis therebetween. A handle is coupled to the proximal end of the shaft assembly, and an elastomeric body housing an image sensor and at least one LED is comprises a distal end of the shaft. The elastomeric body is deformable between a repose straight insertion profile and a deflected offset profile by the insertion of a tool shaft through the shaft assembly and an expandable-collapsible working channel in the elastomeric body. The viewing angle of the image sensor is moved from a first selected angle to a second selected angle when the elastomeric body is actuated from the repose profile to the deflected offset profile.

Abstract: A bipolar electrosurgical devices and methods of use for coagulation and ablation of tissue in a fluid-immersed working space is disclosed. The bipolar electrosurgical device can comprise a handle and an elongated shaft coupled to the handle. The bipolar electrosurgical device can further comprise a bipolar electrode arrangement and a return electrode. The bipolar electrode arrangement and the return electrode can be electrically insulated from one another. The bipolar electrosurgical device can further comprise an adjusting member carried by the elongated shaft. Movement of the adjusting member from a first position toward a second position can contemporaneously increase an effective surface area of the active electrode and decrease an effective surface area of the return electrode.

Abstract: Endoscopes include a shaft having a diameter extending about a longitudinal axis to a distal housing. An image sensor is carried by the distal housing, and a channel extends through the shaft and distal housing. A distal portion of the channel is adjustable or curved to accommodate introduction of a tool while maintaining a reduced shaft diameter. In some embodiments, a diagonal dimension of the image sensor when combined with a channel diameter is greater than a shaft diameter. In some embodiments, the distal housing is flexible to accommodate passage of a straight tool through a curved distal portion of a working channel. In some embodiments, a curved distal portion of a working channel may be reoriented to deflect a flexible tool.
