  • Patent number: 9392935
    Abstract: Methods are disclosed, for performing therapeutic or diagnostic procedures at a remote site. According to one embodiment, the methods include the use of a system including an introducer designed for transcervical insertion into the uterus. The introducer is constructed to include a fluid lumen, an instrument lumen, and a visualization lumen. The system may include a fluid source, which is coupled to the fluid lumen and is used to deliver a fluid to the uterus either for washing the uterus or for fluid distension of the uterus. The system additionally includes a tissue modifying device, such as a morcellator, and a distension device for distending the uterus and/or for maintaining the uterus in a distended state. The tissue modifying device and the distension device are alternately deliverable to the uterus through the instrument lumen. The system may further include a hysteroscope deliverable to the uterus through the visualization lumen.

  • Publication number: 20080249366
    Abstract: A system for performing a medical procedure and an introducer device suitable for use in the system. The system may be used, for example, to examine and/or to treat the uterus. According to one embodiment, the system includes an introducer, a morcellator, a flexible hysteroscope, and a fluid-containing syringe. The introducer is suitable for transcervical insertion into the uterus and includes a gun-shaped housing and a rigid sheath extending distally from the housing. The sheath is shaped to include an instrument lumen, a visualization lumen, and a pair of fluid lumens. The introducer also includes a first assembly within the housing for receiving the morcellator and for guiding the distal end of the morcellator into the instrument lumen and a second assembly within the housing for guiding the hysteroscope into the visualization channel. In addition, the introducer further includes an assembly for fluidly connecting the syringe to the fluid lumens.

  • Patent number: 5484219
    Abstract: A compliancy joint for a robot has six degrees of compliancy freedom and comprises a housing having an inner ring. A float block is movably disposed in the interior of the housing and a plurality of circumferentially arranged pneumatic cylinders on the housing apply force circumferentially to the float block. Sensors are used to detect when the float block is near its compliancy limit and a controller is operatively connected to the sensors and the cylinders for preventing the float block from reaching its compliancy limit. This joint is able to break away from the robot should the robot exceed the device's compliancy limit, preventing damage to the robot and robot end of arm tooling.
