  • Patent number: 9730690
    Abstract: One embodiment is directed to a method for providing surgical access across a wall of a tissue structure, comprising: installing a guiding member into the wall of the tissue structure to a desired guiding depth; using the installed guiding member as a positional guide, advancing a helical member into the wall of the tissue to a desired helical member depth, the helical member comprising a helical member distal end removably coupled to an anchor member which is coupled to a distal end of a suture member, such that advancing the helical member into the wall causes the anchor member to be advanced into the wall and to pull a distal portion of the suture member along with the anchor member into the wall to substantially encapsulate a number of helical loops of suture member that is greater than about 1 loop and less than about 3 loops; withdrawing the helical member from the wall of the tissue structure, leaving the anchor member in a deployed configuration decoupled from the helical member and coupled to at leas

  • Patent number: 9622774
    Abstract: Embodiments are described for creating and closing tissue access ports, such as transapical access ports, which involve placement of an introducer across the subject tissue structure, and deployment of a controllable port closure device assembly configured to remain in place with a ratcheting mechanism, and to hold the tissue surrounding the previous access port location closed against a sealing disc with proximal and distal strut assemblies, after the introducer has been removed.

  • Patent number: 9398910
    Abstract: One embodiment is directed to a method for providing surgical access across a wall of a tissue structure, comprising: advancing a helical needle into the wall of the tissue structure such that the needle pulls an intercoupled suture member across the wall to form a deployed suture pattern, the deployed suture pattern being characterized in that: the portion of the suture member encapsulated by the wall of the tissue structure is substantially helical in formation and represents a number of helical loops that is greater than about one helical loop, and is less than about three helical loops; portions of the suture member on either side of the wall are in a slack configuration such that tension in the suture member arising from the encapsulated portion pulls in additional length from the slack configuration on either side of the wall to accommodate expansion of the substantially helical encapsulated portion.

  • Publication number: 20160151059
    Abstract: Configurations are described for conducting minimally invasive medical diagnoses and interventions utilizing elongate instruments and assemblies comprising one or more imaging devices, and one or more remote retraction and distraction devices. Retraction and distraction devices, such as balloons, mechanical retraction members, and/or trocar screw geometries may be utilized to access, investigate, and intervene at the joint capsule, or inside of the joint capsule. Imaging devices, such as optical image capture devices, ultrasound transducers, and optical coherence tomography fibers, may be utilized to assist with navigation of the pertinent tools during diagnostic and interventional steps.
