Embodiments systems and methods for a platform that is configured to hold a medical device. In embodiments, a physician, nurse, medical practitioner, etc. may perform actions to change the positioning and orientation of the medical device while the medical device is secured to the platform. In further embodiments, the platform may include robotic components configured to change the positioning and orientation of the medical device.

Components, systems and kits for capturing and removing tissue from mammalian bodies include a tissue container that may be introduced into a body cavity and within which a tissue specimen may be placed, cut and removed from the body cavity. Methods of using these components, systems and kits are also described.

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.

A surgical system can include a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument can include a second channel. A valve coupled to the first instrument controls fluid flow through the first channel. The valve has at least two positions and in one position, the impedance of fluid flow through the valve into the first channel (when the second instrument is not received in the first channel) is substantially the same as when the valve is the other position and the first channel partially blocked by the second instrument. In another aspect, a surgical system can include an outer member and the first instrument can be received within the outer member to define a second channel there between. The first instrument can include a visualization system and an illumination system.

A vaginal manipulator includes a head, a tissue index, a door, and a head extender. The head has a first end connected to a shaft and a distal end opposite of the first end. The tissue index is disposed laterally across the head and is adapted to slide in a longitudinal direction between the first end and the distal end of the head. The door has a pivot portion attached to a distal portion of the head and a free portion that is movable away from the head. The head extender includes a post that is insertable into an orifice formed in the distal end of the head.

Delivery systems, and methods using the same, having an ultrasound viewing window for improved imaging and a needle for ablation treatment of target tissues. In an embodiment, the target tissue is a fibroid within a female's uterus. In an embodiment, the delivery system includes a rigid shaft having a proximal end, a distal end, and an axial passage extending through the rigid shaft. In an embodiment, the axial passage is configured for removably receiving the ultrasound imaging insert having an ultrasound array disposed a distal portion.

A fluid infusion system includes an air pump connected to an accumulator tank to produce pressurized air that is stored in the accumulator tank. The system can include one or more fluid bag chambers wherein each fluid bag chamber includes an inflatable bladder positioned inside the fluid bag chamber to apply pressure on the fluid bag supported inside the chamber. The fluid bag can be connected by a tube set to deliver fluid from the fluid bag to a surgical tool at a surgical site. The fluid can, for example, be irrigation fluid or distention fluid. The system can include a controller connected to the pump to control the pump to produce the pressurized air and an adjustable pressure regulator can be connected between the accumulator tank and the inflatable bladder to control the pressure of air delivered to the inflatable bladder and the pressure that the fluid is delivered to the surgical tool. A pressure sensor can be connected between the adjustable pressure regulator and the inflatable bladder to measure the air pressure delivered to the inflatable bladder and send the air pressure measurements to the controller. The controller can configure the system display to show the air pressure measured by the pressure sensor.

A method includes: delivering a biodegradable expandable member into a body cavity of a patient; insufflating the biodegradable expandable member in the body cavity to expand the body cavity; sealing the biodegradable expandable member against an inner wall of the body cavity to seal the body cavity internally; and delivering an endoscope into the body cavity.

The invention generally relates to intracavitary medical devices and methods for using the devices. In one aspect, the devices comprise: a tube comprising a longitudinal body having opposed proximal and distal ends, and at least three lumens extending there between; and an expandable balloon region located at the distal end of the tube; wherein at least one lumen comprises at least one of: a drainage lumen which opens at a portion of the distal end of the tube and configured to allow fluid communication from a body cavity into the drainage lumen, an inflation lumen connected to an interior of the balloon region and configured to enable passage of a distending fluid to control expansion and contraction of the balloon region, and an instillation lumen which opens at a portion of the distal end of the tube and configured to allow a fluid to be introduced from the instillation lumen into the body cavity.
