  • ENDOSCOPE AND METHOD OF USE
    Publication number: 20180184892
    Abstract: Endoscope systems include an endoscope shaft assembly which comprises a shaft having a working channel, an inflow channel configured to be coupled to a fluid source, and an outflow channel configured to be coupled to a negative pressure source. A hub is coupled to a proximal portion of the shaft, and an image sensor is disposed on a distal portion of the shaft. A control unit is configured to adjust both a fluid inflow from the fluid source through the inflow channel to the working space and a fluid outflow to the negative pressure source through the outflow channel from the working space. A handle assembly is detachably connected to the hub of the endoscope shaft assembly, and the handle assembly comprises a control pad having at least one actuator which may be wired or wirelessly linked to the controller for adjusting fluid inflows and outflows through the inflow channel and outflow channel in the shaft.

  • Tissue resecting devices and methods
    Patent number: 10004556
    Abstract: A tissue-resecting probe includes an elongated outer sleeve extending about an axis to a distal housing having a first window for receiving tissue. An edge of the first window has a dielectric surface. A rotatable inner sleeve has a second window, and at least a portion of an edge of the second window provides a first polarity electrode. Rotation of the inner sleeve within the outer sleeve moves the probe between window-open and window-closed configurations to resect tissue.

  • Tissue extraction devices and methods
    Patent number: 9999466
    Abstract: Tissue may be cut and extracted from an interior location in a patient's body using a probe or tool which both effects cutting and causes vaporization of a liquid or other fluid to propel the cut tissue through an extraction lumen of the cutting device. The cutting may be achieved using an electrosurgical electrode assembly, including a first electrode on a cutting member and a second electrode within a cutting probe or tool.

  • ENDOSCOPE AND METHOD OF USE
    Publication number: 20180160893
    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.

  • TISSUE EXTRACTION DEVICES AND METHODS
    Publication number: 20180071015
    Abstract: The tissue cutting device comprises an elongated assembly including both an outer sleeve and an inner sleeve. The outer sleeve has a tissue-receiving window, and the inner sleeve has a distal end which cuts tissue as the inner sleeve is advanced past the window. The tissue is received into a lumen of the inner sleeve, and the inner sleeve lumen is typically enlarged in a proximal direction to reduce the tendency of resected tissue to lodge therein. The tissue displacement member is optionally provided at a distal end of the outer sleeve to further aid in dislodging tissue which becomes captured in a distal end of the inner sleeve of the lumen.

  • SYSTEM AND METHOD FOR ENDOMETRIAL ABLATION
    Publication number: 20180055561
    Abstract: A wall of a uterus is ablated by expanding a structure in the uterus and applying energy across the wall of the structure into the uterine wall. An exterior surface of the structure conforms to an inner wall of the uterus, and the energy may cause vapor to collect between the wall and the structure. The vapor is released by providing a barrier to release which is inflated at a pressure above which the barrier at least partially collapses to allow the vapor to leave the uterus.

    Patent number: 9901657
    Abstract: A system for use in bone cement preparation can include a chamber for intermixing a liquid monomer and solid polymer components, a container, a vacuum channel, and a filter. The mixing chamber can be configured to hold a non-liquid, polymer powder component of a bone cement. The container can be configured to hold a liquid component of the bone cement. The system can have a first interface disposed between the mixing chamber and the container and a second interface disposed between the mixing chamber and the vacuum channel. The second interface can to receive and position the filter between the mixing chamber and the vacuum channel. The vacuum channel can direct a partial vacuum to draw the liquid component from the container into the non-liquid component in the mixing chamber to intermix the components and to thereby provide a settable bone cement.

  • SYSTEM FOR USE IN TREATMENT OF VERTEBRAL FRACTURES
    Publication number: 20180028199
    Abstract: Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.
