Abstract: A method of treating a gynecological malignancy includes introducing an implant within a uterus of a patient and positioning the implant adjacent to an endometrium of the uterus to enable a bioactive agent supported on the implant to treat the gynecological malignancy. The implant may be one or more deployable implants including a balloon, an IUD, a stent, or combinations thereof. Such implants may be introduced by one or more surgical instruments.

Abstract: An infusion catheter includes a housing, a proximal shaft assembly, a first distal shaft assembly and a second distal shaft assembly. The housing has one or more inflation ports and one or more infusion ports. The proximal shaft assembly supports a first balloon. The first distal shaft assembly extends distally from the proximal shaft assembly and supports a first distal balloon. The second distal shaft assembly extends distally from the proximal shaft assembly and supports a second distal balloon. The first and second distal shaft assemblies define infusion openings in fluid communication with the one or more infusion ports. The infusion catheter may be inserted into a uterine cavity to occlude tubal ostia and an internal cervical OS of the uterine cavity for sealing the uterine cavity. A therapeutic agent may be delivered through the infusion catheter and into the sealed uterine cavity to treat the uterine cavity.

Abstract: A method of determining a pressure of a body cavity with a controller of a fluid management system includes determining a pressure and a volume of a cuff disposed about a collapsible bag, determining a volume of the collapsible bag based on the pressure and the volume of the cuff, and determining a pressure of the collapsible bag based on the volume of the collapsible bag. The method also includes calculating a fluid flow from the collapsible bag into a body cavity from the collapsible bag and determining a pressure of the body cavity based on the fluid flow.

The upper and lower retainers are configured to retain the collection vessel thereon in the expanded configuration.

Abstract: A fluid collection system includes a vacuum source, a collection vessel, and a surgical drape. A fluid outflow line is connected between the surgical drape and the collection vessel. The fluid outflow line provides a path for fluid to the collection vessel. A suction line is connected with the collection vessel. The suction line provides suction to draw fluid through the fluid outflow line to the collection vessel. The suction line branches into a first suction line and a second suction line parallel with the first suction line. The first suction line and the second suction line are each connected with the vacuum source. A flow restrictor is disposed along the first suction line. A valve is disposed along the second suction line. The valve is opened in a pulsatile fashion when fluid is present in the surgical drape to increase a level of suction provided to the surgical drape.

Abstract: A surgical instrument includes a handpiece including a housing and a motor disposed in the housing. An end effector assembly is operably coupled to the handpiece. The motor actuates the end effector assembly. A temperature measurement assembly is in the housing. The temperature measurement assembly measures a temperature of the motor. The temperature measurement assembly includes a printed circuit board (PCB) including an orifice extending through the PCB. An infrared (IR) sensor is on the PCB. The IR sensor transmits IR light to a temperature measurement location of the motor through the orifice of the PCB. The IR sensor detects IR light reflected from the temperature measurement location of the motor to determine a temperature of the temperature measurement location of the motor.
