  • Patent number: 11135072
    Abstract: A total artificial expansile disc and a method for posterior insertion between a pair of vertebral endplates are disclosed. The total artificial expansile disc includes at least one pair of substantially parallel plates that move apart along a first axis, in order to occupy a space defined by the vertebral endplates. In another embodiment, each of substantially parallel plates includes a first plate and a second sliding plate. An expansion device or tool is used to move the substantially parallel pair of plates apart along the first axis. A core is disposed between the pair of plates, and the core permits the vertebral endplates to move relative to one another. A ball limiter or ball extender prevents the core from being extruded from between the substantially parallel plates.

  • Patent number: 11083488
    Abstract: A device for insertion of a flexible needle or other such instrument into a tissue, incorporating a collapsible support guide which supports that part of the needle which has not yet penetrated the tissue, preventing it from buckling, and an arrangement which pulls the needle from its proximal end to provide sufficient force for the penetration process. The collapsible support guide can be a pair of flexible strips connected along their length and enclosing the needle along its uninserted length in order to support it, with a mechanism at the distal end of the device to peel the strips from the needle as it is inserted. Insertion can be achieved by a pair of rollers engaging and advancing the strips distally. Alternatively, a telescopic support tube can be used to support the needle, the tube collapsing telescopically as the needle is inserted, to maintain clearance above the needle.

  • Publication number: 20200275980
    Abstract: A system and method for ensuring safe and tolerable insertion of a needle into a subject's body according to a preplanned or continuously monitored sequence of insertion steps. The system comprises a gripping device for gripping the needle in order to perform robotic insertion steps, yet for releasing the grip between such insertion steps, until the next insertion step is initiated. Thereby, the robot has full control of the needle during insertion steps, but does not constrain the needle between insertions, such that movement of the subject can cause neither damage nor discomfort. The gripping and insertion steps may be coordinated to keep in synchronization with the subject's breathing cycles, such that the insertion steps may be performed in the same segment of each cycle of motion of the subject's chest. The gripper can either fully disconnect from the needle, or can partially disconnect but constrain motion within limits.

    Abstract: An apparatus and method for joining members together using a self-drilling screw apparatus or stapling apparatus are disclosed. The screw apparatus includes a worm drive screw, a spur gear and superior and inferior screws which turn simultaneously in a bi-directional manner. A rotating mechanism drives the first and second screw members in opposite directions and causes the screw members to embed themselves in the members to be joined. The screw apparatus can be used to join members such as bones, portions of the spinal column, vertebral bodies, wood, building materials, metals, masonry, or plastics. A device employing two screws (two-in-one) can be combined with a capping horizontal mini-plate. A device employing three screws can be combined in enclosures (three-in-one). The stapling apparatus includes grip handles, transmission linkages, a drive rod a fulcrum and a cylinder.

  • Publication number: 20200179066
    Abstract: A method and apparatus for steering of a flexible needle into tissue using a steering robotic platform for manipulation of the needle shaft, and by use of a semi-active arm for locating and orienting of the steering robot on the patient's body. As opposed to other steering methods, the robot does not hold the base of the needle, which is its proximal region, but rather grips the shaft of the needle by means of a manipulatable needle gripping device, near its distal end. The needle gripper attached to the robotic platform may be equipped with a traction assembly to provide motion to the needle in its longitudinal direction, such that it co-ordinates the entry of the needle with the desired entry angle. The gripping of the needle at its distal end, close to its insertion point, provides the needle manipulator with a low profile, with concomitant advantages.

  • Publication number: 20200078506
    Abstract: Apparatus and methods are described including manufacturing an impeller by coupling a material to a helical elongate element, such that the helical elongate element with the material coupled thereto defines a blade of the impeller. A portion of a structure that includes the helical elongate element is dipped into the material while the material is in a liquid state. The material is dried, while the material is being supported by the at least one helical elongate element. During the drying of material, the structure is rotated about its longitudinal axis, such as to facilitate the formation of a film of the material having a substantially uniform thickness within the impeller blade. Other applications are also described.
