  • Patent number: 11963873
    Abstract: Systems and methods for modifying a heart valve annulus in a minimally invasive surgical procedure. A helical anchor is provided, having a memory set to a coiled shape or state. The helical anchor is further configured to self-revert from a substantially straight state to the coiled state. The helical anchor is loaded within a needle that constrains the helical anchor to the substantially straight state. The needle is delivered to the valve annulus and inserted into tissue of the annulus. The helical anchor is then deployed from the needle (e.g., the needle is retracted from over the helical anchor). Once deployed, the helical anchor self-transitions toward the coiled shape, cinching engaged tissue of the valve annulus.

  • Patent number: 11950785
    Abstract: An ischemia control device is connected to a control unit that receives inputs from sensors and other surgical devices that senses patient conditions. The control unit uses the data inputs, as well as direct inputs from the medical operators, to output opening and closing instructions to the ischemia control device. The actuator on the ischemia control device receives the opening and closing instructions and manipulates the ischemia control device. The ischemia control device can be automatically operated using the sensed information to intermittently and alternately achieve ischemia of the organs and reperfuse the organs and, thereby, protect the organs from being damaged by the ischemia.

  • Patent number: 11944506
    Abstract: A method of setting a cannula lock. An orientation of a bore of a brake is set by rotating a base and a head of the brake about at least one axis. An actuator is actuated to cause relative movement between the head and the base to engage internal surfaces of the shell to fix the orientation of the bore. A device may be directed through the bore and into tissue along a trajectory established by the orientation of the bore. The actuator may be rotated about its longitudinal axis to move the head and the base away from one another. Anchors coupled to the shell may be embedded into the section of tissue. The actuator may be an extraction tool for extracting a drive ring from the base of the shell to permit unembedding of the anchors from the tissue. The head and the base may be semi-spherical.

  • Patent number: 11931043
    Abstract: A clip device for gripping biological tissue of a patient includes a clip having a first arm and second arm closeable by operation of a wire that is reciprocally moveable in a longitudinal channel of a sheath; and a bendable member at a distal end region of the sheath. The bendable member can be an integral portion of the sheath or a separate structure. The bendable member is configured to allow a distal end of a clip to rotate or swing toward a proximal end region of the sheath of the device, which orients the clip relative to the sheath to facilitate grasping of tissue even when the approach of the clip is tangential to the tissue, e.g., at an angle (?) less than 90. The bendable member can be configured to allow a distal end of a clip to rotate or swing toward a proximal end region of a sheath and form an angle of up to at least about 45 degrees, such up to about 60 degrees or up to about 90 degrees, or higher.

  • Patent number: 11911259
    Abstract: A tubular, folding flow diverter is provided. The flow diverter includes a plurality of sections, including a first section, a second section, and a third section. The flow diverter is shapeable to an elongated cylindrical shape and is movable to an implanted configuration. In the implanted configuration, the second section and at least a portion of the first and third sections overlap to form a three-layer shape. This three-layer shape can be positioned proximate an aneurysm neck when implanted in a patient. The overall porosity of the implant can be higher than legacy implants, because the overlapping portion of the three sections can decrease the porosity proximate the aneurysm neck.

  • Patent number: 11896484
    Abstract: The present application discloses an implant loading apparatus comprising a guider and a guide base. The guider is sleeved on the exterior of the guide base. The guide base comprises a guide column, a connecting section, and a base connected in the axial direction. Fixing sections are provided on either end of the connecting section. The guide base is removably connected to the guider via the fixing sections. The guide base is provided with the two fixing sections that fit the guider to implement twice removable fixing, thus favoring a coaxial operation. A valve stent is neither twisted nor tilted during a compression process, thus increasing loading efficiency, greatly reducing the operation difficulty of a surgery, and allowing the implementation of a single person operation.
