  • Patent number: 10959832
    Abstract: A soft tissue fixation system, most typically applicable to orthopedic joint repairs, such as anterior cruciate ligament (ACL) knee repair procedures, comprises an implant which is placeable in a tunnel disposed in a portion of hone, wherein the tunnel is defined by walls comprised of bone. A first member is deployable outwardly to engage the tunnel walls for anchoring the implant in place in the tunnel, and a second member is deployable outwardly to engage tissue material to be fixed within the tunnel. The second member also functions to move the tissue material outwardly into contact with the tunnel walls to promote tendon-bone fixation. Extra graft length is eliminated by compression of the tendon against the bone at the aperture of the femoral tunnel, which more closely replicates the native ACL and increases graft stiffness. The inventive device provides high fixation of tendon to bone and active tendon-bone compression.

    Abstract: In this patent disclosure, a machine-learning-based system for automatically turning on/off a light source of an endoscope camera during a surgical procedure is disclosed. The disclosed system can receive a sequence of video images captured by the endoscope camera when the light source is turned on. The system next analyzes the sequence of video images using a machine-learning classifier to classify each video image as a first class of image of being inside the patient's body or a second class of image of being outside of the patient's body. The system next determines whether the endoscope camera is inside or outside of the patient's body based on the classified video images. When the endoscope camera is determined to be outside of the patient's body, the system generates a control signal for turning off the light source, wherein the control signal is used to immediately turn off the light source.

  • Patent number: 10716549
    Abstract: Embodiments of the present disclosure are directed to medical devices for treating a target site. For example, a medical device comprises a tubular member having a proximal end and a distal end, the tubular member having an expanded preset configuration when deployed at the target site and a reduced configuration for delivery to the target site. The tubular member comprises at least one layer of braided fabric, and the at least one layer of braided fabric comprises a plurality of first strands having a first diameter and a plurality of second strands having a second diameter. The first diameter is larger than the second diameter. The plurality of first strands and the plurality of second strands are intertwined to define regions of varying radial stiffness between the proximal and distal ends of the tubular member.

  • Patent number: 10682128
    Abstract: A vascular closure device includes a deployment assembly, a sealing unit carried by the deployment assembly, and a tamper carried by the deployment assembly and that is disposed along a suture with respect to the sealing unit. The vascular closure device includes a locking assembly coupled to the tamper so as to selectively inhibit advancement of the tamper along the suture in the distal direction toward the sealing unit. The locking assembly is adapted to transition from A) a locked configuration where the tamper is inhibited from sliding along the suture, into B) an unlocked configuration where the tamper is slidable along the suture in the distal direction and into contact with the sealing unit.

  • Patent number: 10675017
    Abstract: An apparatus for repairing a heart valve can comprises a leaflet-plicating mechanism configured to plicate a leaflet of a heart valve and a helical needle comprising a plurality of coils. The needle can be configured to implant a suture to extend helically through plicated tissue of the heart valve. The leaflet-plicating mechanism can comprise first and second leaflet-capture arms, which can be configured to move toward and away from each other between an open position and closed position. The leaflet-capture arms can be configured to plicate the leaflet as the leaflet-capture arms are moved from the open position to the closed position.

  • Patent number: 10675090
    Abstract: A microwave ablation system includes a generator including a first energy source, a second energy source and a diplexer, the diplexer multiplexes a first energy from the first energy source and a second energy from the second energy source. The system also includes a cable including a center conductor and an outer sheath where the multiplexed energy is transmitted through the center conductor. In addition an antenna is provided that is operable to receive the multiplexed energy from the center conductor and to deliver the multiplexed energy to a region of tissue. The outer sheath acts as a return path of the second energy to the second energy source. A sensor is also provided that measures at least one parameter of the second energy generated by the second energy source and the second energy returned from the region of tissue.

  • Patent number: 10667815
    Abstract: A tissue gripping device is formed from a shape-memory material, and has a base section, a first arm, and a second arm disposed opposite the first arm, each arm having a first end coupled to the base section and a free end extending from the base section. The arms of the tissue gripping device are configured to resiliently flex toward a relaxed configuration in a distal direction as the tissue gripping device is moved from a pre-deployed configuration toward a deployed configuration. The tissue gripping device is usable in a method for gripping tissue. The method includes positioning the tissue gripping device near target tissue and moving the tissue gripping device from a pre-deployed configuration toward a deployed configuration in order to grip the target tissue.

  • Patent number: 10631969
    Abstract: Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a medical device includes an occluder portion and an anchor portion. The occluder portion includes a hub that defines an axis, the occluder portion extending between a proximal end coupled to the hub and a distal end defining an occluder eyelet adjacent thereto. The anchor portion extends between a first end and a second end, the first end coupled to an anchor hub and the second end defining an anchor eyelet adjacent thereto and hingeably coupled to the occluder eyelet. With this arrangement, the anchor hub is moveable along the axis to move the anchor portion between a retracted position and a deployed position upon the occluder portion being in an expanded position.
