  • Patent number: 9883907
    Abstract: Methods, systems and devices for evaluating the integrity of a uterine cavity. A method comprises introducing transcervically a probe into a patient's uterine cavity, providing a flow of a fluid (e.g., CO2) through the probe into the uterine cavity and monitoring the rate of the flow to characterize the uterine cavity as perforated or non-perforated based on a change in the flow rate.

  • 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.

  • Patent number: 9839473
    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.

  • Publication number: 20170333120
    Abstract: A tissue resecting device includes an elongated shaft having a central axis, a distal end, and a proximal end. A ceramic or other housing is mounted at the distal end of the shaft and has a tissue-receiving window. A movable electrode is configured to be rotationally oscillated or otherwise moved across the window. In one instance, the rotatable moveable electrode may have a dogleg configuration with a free end constrained within an arcuate slot formed near the window. In another instance, the movable electrode may have a U-shaped configuration with a distal end coupled to a pivot in the housing which is aligned with a rotational drive member.

  • Publication number: 20170333103
    Abstract: The present invention relates in certain embodiments to medical devices for treating vertebral compression fractures. More particularly, embodiments of the invention relate to instruments and methods for controllably restoring vertebral body height by controlling the flow of bone cement into the interior of a vertebra and the application of forces causes by the cement flow. An exemplary system utilizes Rf energy in combination a conductive bone cement for selectively polymerizing the inflow plume to increase the viscosity of the cement. In one aspect of the invention, the system utilizes a controller to control bone cement flow parameters to either allow or disallow cement interdigitation into cancellous bone. A method of the invention includes pulsing the flows of bone cement wherein high acceleration of the flow pulses can apply expansion forces across the surface of the cement plume to reduce a vertebral fracture.

  • Patent number: 9821085
    Abstract: The present disclosure relates to bone cement formulations that have an extended working time for use in vertebroplasty procedures and other osteoplasty procedures together with cement injectors that include energy delivery systems for on-demand control of cement viscosity and flow parameters. The bone cement formulations may include a liquid component having at least one monomer and a non-liquid component including polymer particles and benzoyl peroxide (BPO). The non-liquid component may be further configured to allow controlled exposure of the BPO to the liquid monomer so as to enable control of the viscosity of the bone cement composition.

  • Patent number: 9814520
    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.

  • Publication number: 20170231681
    Abstract: Systems and methods for endometrial ablation. The systems include a handle and elongated introducer sleeve extending to an expandable working end having a fluid-tight interior chamber. A thin dielectric wall surrounds at least a portion of the interior chamber and has an external surface for contacting endometrial tissue. The thin dielectric wall surrounds a collapsible-expandable frame and receives an electrically non-conductive gas. First and second polarity electrodes are exposed to the interior and exterior of the chamber, respectively. A radiofrequency power source operatively connects to the electrode arrangement to apply a radiofrequency voltage across the first and second electrodes, wherein the voltage is sufficient to initiate ionization of the neutral gas into a conductive plasma within the interior chamber, and to capacitively couple the current in the plasma across the thin dielectric wall to ablate endometrial tissue engaged by the external surface of the dielectric structure.
