    Abstract: Suture constructs and methods are provided for securing soft tissue to bone. One exemplary embodiment of a construct includes a first limb, a second limb, a coaxial region, and a collapsible snare defined by the first and second limbs. The coaxial region can be formed by a portion of the second limb being disposed in a volume of the first limb, which allows for a low profile construct that is useful in various soft tissue repair procedures. The construct can be configured to be disposed in tissue to draw the tissue toward bone, and the coaxial region can be deconstructed so that the first and second limbs can be used to help secure the desired location of the tissue with respect to the bone. Various features of the construct and methods for using the same in a surgical procedure are also provided.

  • Patent number: 11357592
    Abstract: Minimally invasive robotic surgical instruments and related methods are disclosed. A surgical instrument includes an interface fitting that couples a proximal chassis of the instrument with a holding fixture of a robotic manipulator. A securing feature releasably prevents relative axial sliding between the interface fitting and the chassis. In response to binding of the surgical instrument within a minimally invasive surgical site so as to inhibit removal of the surgical instrument from the surgical site and inhibit disengagement of the interface fitting from the holding fixture, the securing feature can be released to allow relative axial sliding between the interface fitting and the chassis, thereby allowing the holding fixture and the interface fitting to be separated from the rest of the surgical instrument and repositioning of the robotic manipulator out of the way.

    Abstract: An end effector assembly (114) includes a first jaw member (114a) having a first tissue contact surface (122) and a second jaw member (114b) having a second tissue contact surface (122). The second jaw member (114b) is pivotally coupled to the first jaw member (114a). The tissue contact surfaces (122) may include raised steps (122b) that define an exhaust channel (124). A longitudinally extending knife slot (214) may be defined in one or both of the tissue contact surfaces (122). One or more exhaust slots (216), which may be defined in one or both of the tissue contact surfaces (122), are in communication with the knife slot (214). The exhaust channel (124) and the exhaust slots (216) direct fluid away from the jaw members (114a, 114b) to minimize thermal damage risks associated with tissue sealing.

  • Patent number: 11224422
    Abstract: A device for securing an article to a tissue may include a body, transitionable from a deployment state to a securing state, having a first portion, a second portion, and a medial portion therebetween. The first portion and the second portion may each have an end configured to pierce the tissue. The device in the deployment state may have a linearly extended or a U-shaped structure. In the securing state, the first portion may be embedded in the tissue and the medial portion may contact the article. A system for securing the article to the tissue may releasably engage the device while in the deployment state. A method for securing the article may include contacting the article with a tissue surface and releasing the device from the system so that the device, in the securing state, may anchor the article to the tissue.

  • Patent number: 11173030
    Abstract: Disclosed herein are various embodiments of suture adjustment mechanisms for anchors configured to be inserted into a heart wall of a patient to anchor a suture as an artificial chordae under an appropriate tension for proper valve function. Suture adjustment mechanisms can be configured to retain suture ends extending from the leaflet to the anchor with sufficient force to prevent natural movement of the leaflet from adjusting a length of the suture between the anchor and the leaflet. Free ends of the suture can extend from the anchor external to the body as tensioning strands. A surgeon can supply sufficient force on the tensioning strands from external the body to adjust a length and tension of the suture between the anchor and the leaflet.

  • Patent number: 11154285
    Abstract: A device is provided to assist in closing an incision through body tissue that comprises a tubular body sized for introduction through the incision and carrying a plurality of stabilizer elements at the distal end thereof. The stabilizer elements are configured to be deployed within the body cavity to engage the lowermost tissue layer. In one method, the device is pulled with the stabilizer elements deployed to retract the body tissue away from adjacent body structure. In another method, a plurality of needle tips carrying sutures are guided through the body tissue to a retention device at the ends of the stabilizer elements. With the needle tips captured in the retention devices, the device is withdrawn from the incision so that the sutures form ligatures that can be tied off to close the incision.
