  • Patent number: 9585648
    Abstract: A retractor having an elongate body that provides access to a surgical location within a patient. The elongate body includes a plurality of segments that are connected to one another through a plurality of ratcheting mechanisms. The ratcheting mechanisms permit relative movement of the segments with respect to one another when expander dilators are inserted within the retractor. The segments are surrounded and retained by a resilient elastomeric sleeve or bands. The distal end surfaces of the segments include thin edges that are configured to mobilize, dissect, split and retract the terminal tissues in the surgical area. The retractor is used in conjunction with a resilient elastomeric pad that is affixed to the patient and firmly engages the outer surface of the elongate body to thereby anchor the retractor to the patient. A separate anchoring device can be used to connect the retractor to the pad.

  • Patent number: 9486227
    Abstract: The robotic mechanism may be used to position a tissue retractor assembly relative to body tissue. Once the tissue retractor assembly has been positioned relative to the body tissue by the robotic mechanism, the robotic mechanism effects operation of the tissue retractor assembly from a contracted condition to an expanded condition to move body tissue. This movement of body tissue may advantageously create a space for the performance of a surgical procedure by the robotic mechanism. Embodiments may facilitate the insertion of one or more surgical instruments through a cannula to a working space created by expansion of a balloon or bladder from the contracted condition to the expanded condition. As the bladder or balloon expands, portions of body tissue are deflected under the influence of force applied to the body tissue by the bladder or balloon.

  • Patent number: 9463107
    Abstract: Transoral obesity treatment devices and related methods for operation thereof are described which occupy space within a stomach and/or stimulate the stomach wall. The transoral obesity treatment devices and related methods are intended to assist a patient in maintaining a healthy body weight. Features of the devices include insertion transorally and without invasive surgery, without associated patient risks of invasive surgery, and without substantial patient discomfort. The life span of these devices may be material-dependent upon long-term survivability within an acidic stomach, but is intended to last one year or longer. The devices have the capacity to vary in size and are desirably self-actuating in that they change shape and/or volume using internal motors or actuators. The changing character of the devices helps prevent the person's stomach from compensating for the implant, such as sometimes happens with static intragastric devices.

  • Patent number: 9393005
    Abstract: A surgical access system facilitates access to a surgical site within a patient's body through an incision in the body. Surgical access systems can have at least one retention member and a fluid transportation member configured to deliver fluid to a surgical site or to remove fluid from a surgical site. In some embodiments, a surgical access device irrigates a surgical site to reduce surgical site infections and removes fluid from the surgical site to increase a physician's visibility into the surgical site.

  • Patent number: 9364257
    Abstract: A cannula assembly includes a cannula adapted for insertion within tissue and having a longitudinal passage extending along a longitudinal axis of the cannula for passage of a surgical instrument. An expandable member is mounted to the cannula and longitudinally spaced from a distal end of the cannula. The expandable member is adapted to expand, upon introduction of fluids therein, in a radially outward direction relative to the longitudinal axis whereby the expandable member engages the tissue to facilitate anchoring of the cannula relative to the tissue, and also to expand in a radially inward direction relative to the longitudinal axis and within the longitudinal passage to engage the surgical instrument positioned within the longitudinal passage to facilitate formation of a seal about the surgical instrument.

  • Patent number: 9357908
    Abstract: A blade extending tower is provided for setting blade depth on retractors having telescoping or extending blades. The blade extending tower features a base, a column extending from the base, and mating features on the column configured to engage the blades of a retractor to extend the blades to a desired blade depth. Blade depth of the retractor is set buy sliding the retractor onto the blade extending tower such that the mating features of the blade extending tower engage the blades or the retractor, stopping the blades progression while the rest of the retractor continues along the length of the column. Thus the blades of the retractor are extended from the retractor to a depth determined by the configuration of the blade extending tower.

  • Patent number: 9308001
    Abstract: The instant invention describes a surgical tool for providing cavitations, or void spots, within the interior of body regions. The surgical tool is constructed and arranged to penetrate almost all interior body regions in which formation of a cavity or void space is necessary for diagnostic or treatment purposes. The surgical tool comprises an insertable member receiving structure sized and shaped to receive one or more insertable devices. The interior lumen of the insertable member receiving structure allows the insertable device to slide and/or rotate relative to the insertable member receiving structure and vice versa. At least one insertable member is a cavity forming device which has a plurality of cavity forming members constructed and arranged with spring-like characteristics for traversing between a cavity forming position and a non-cavity forming position. Upon traversal back to the cavity forming position, the displacement members retain their cavity forming structural configurations.
