Patent number: 11908565Abstract: A method for optimizing orthopedic spinal implant survival using preoperative finite element analysis combined with intraoperative stress analysis. Based on clinically relevant data, finite element analysis, and corrected values of spinal parameters, an acceptable long-term stress score is determined for an appropriate implant, which is selected from a set of potential implants, such that the shape of the implant minimizes predicted stress values. From a preoperative medical image set, values of selected spinal alignment parameters are determined; finite element analysis is performed on potential implants to determine stress values; and a selected implant is digitally positioned in the medical image set to create a virtual bone/implant configuration. After the selected implant is inserted and bent to shape, actual stress values are measured intraoperatively.Type: GrantFiled: October 15, 2019Date of Patent: February 20, 2024Assignee: MAZOR ROBOTICS LTD.Inventors: Shlomit Steinberg, Moshe Shoham

Patent number: 11864795Abstract: A minimally invasive system using a surgical robot as a three-dimensional printer for fabrication of biological tissues inside the body of a subject. A preoperative plan is used to direct and control both the motion of the robot and the robotic bio-ink extrusion. The robotic motion is coordinated with the ink extrusion to form layers having the desired thickness and dimensions, and use of different types of ink enables composite elements to be laid down. Such systems have a small diameter bio-ink ejecting mechanism, generally in the form of a piston driven cannula, enabling access to regions such as joints, with limited space. The robotic control is programmed such that angular motion takes place around a pivot point at the point of insertion into the subject. The bio-inks can be stored in predetermined layers in the cannula to enable sequential dispensing from one cannula.Type: GrantFiled: April 2, 2018Date of Patent: January 9, 2024Assignee: MAZOR ROBOTICS LTD.Inventor: Moshe Shoham

Publication number: 20230414289Abstract: A system and method for the minimally invasive insertion of an intervertebral rod into the vertebrae of a subject, according to a preoperative surgical plan also defining positions for the insertion of rod clamping screws into the vertebrae. The rod shape for connecting the heads of the screws is calculated, and a path planning algorithm used to determine whether the distal end of the rod can be threaded through the screw heads by longitudinal and rotational manipulation of the proximal end of the rod. If so, instructions are provided for forming that rod shape and for the robotic insertion of the screw holes and the rod. If not, either or both of the screw positions and the rod shape are adjusted, to moderate the bends in the rods, until insertion becomes possible. The insertion can be performed robotically, or, if a navigation tracking system is added, manually.Type: ApplicationFiled: September 11, 2023Publication date: December 28, 2023Inventors: Edo ZUCKER, Moshe SHOHAM, Yuval CHEN

Patent number: 11851149Abstract: A flotation device for providing emergency flotation for a person swimming or passing through a body of water, comprising a container filled with a charge of a gaseous material under a pressure such that it is in its liquid phase at normal environmental temperatures. The container is connected to a flexible flotation chamber through a passage which remains normally closed until actuated by the user. When the device is actuated by opening the passage, the charge expands into the flotation chamber, thereby inflating it, and providing support to the user in the water. The gaseous material has thermodynamic properties such that it remains in its liquid phase right up to the maximum temperatures to which the device is expected to be exposed to. Consequently, its volume, and hence the internal pressure within the gas container, does not increase significantly, thereby enabling the container to be of lightweight construction.Type: GrantFiled: April 7, 2020Date of Patent: December 26, 2023Assignee: SEA ARK TECHNOLOGIES LTD.Inventors: Oriya Shoham, Moshe Shoham, Matityahu Azriel

Publication number: 20230293215Abstract: A system for rod bending for use in robotic spinal surgery, enabling the correct bending of a fusion rod to match the shape required to accurately pass through the heads of the pedicle screws. The system uses data generated by information provided to the robot by the surgeon's preoperative plan, optionally augmented by feedback from the robot control system of deviations encountered intraoperatively. Such deviations could occur, for example, when the surgeon decides intraoperatively on a different trajectory or even to skip screws on one vertebra, in which case, the robot will be commanded to perform the alternative procedure, with commensurate instructions relayed to the control system of the rod-bending machine. The system is also able to thin down the rod at predetermined locations along its length, adapted to be at selected intervertebral locations, for maintaining limited flexibility between vertebrae, instead of fixating them.Type: ApplicationFiled: May 22, 2023Publication date: September 21, 2023Inventors: Edo Zucker, Moshe Shoham

Publication number: 20230277258Abstract: 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.Type: ApplicationFiled: May 10, 2023Publication date: September 7, 2023Inventors: Daniel GLOZMAN, Gonen DASKAL, Moshe SHOHAM, Michael ARAD, Yoav PINSKY

Publication number: 20230256270Abstract: A device in the form of a cap, for generating an isolation barrier for airborne pathogens between the wearer's face and the environment. A major part of the outer surface comprises filter material, allowing filtered air to flow from the environment into a chamber beneath the surface layer. A fan sucks air through the filter element and into the chamber. A horizontally oriented slot is situated across the visor portion of the cap structure, in front of the forehead of the person when the device is worn by the person. The slot has a width substantially smaller than the length. The flow of filtered air within the chamber is directed out of the slot as a curtain-like flow of filtered air in front of the face of the person. A cross-flow fan mounted just above the slot is most effective in generating the curtain flow.Type: ApplicationFiled: July 15, 2021Publication date: August 17, 2023Inventors: Moshe SHOHAM, David KEISAR, Anan GARZUZI, David GREENBLATT

Patent number: 11701099Abstract: A balloon dilator device, comprising an annularly shaped, cylindrical type structure having walls that are expandable from a radially collapsed state to a radially expanded state by inflation of a balloon inserted within the annular structure. Once the walls have been expanded, they remain in the expanded state even if the balloon is deflated, because the radially expanded state is a state of minimum mechanical potential energy, and in order to return to the collapsed state, the structure would have to pass a state of higher potential energy. The device walls require sufficient stiffness in their longitudinal direction to enable the device to be pushed into a minimally invasive incision made in the subject. This device stiffness can be achieved either by its mechanical material properties, or by its substantially closed wall structure, or by use of a stiff protector sheath used to protect the walls during insertion.Type: GrantFiled: May 15, 2017Date of Patent: July 18, 2023Assignee: MAZOR ROBOTICS LTD.Inventors: Yossef Bar, Moshe Shoham

Patent number: 11623717Abstract: An inflatable flotation device having a reaction chamber with reactants that generate gas when mixed, said reactants being separated by a barrier assembly; an activating mechanism adapted to remove or puncture the barrier assembly such that said reactants mix; and an inflatable compartment fluidly connected to the reaction chamber by means of a pressure sensitive passageway, adapted to open only when the pressure of the gas in said reaction chamber exceeds a predetermined threshold. This ensures that most of the reactants are used up to generate gas before the gas enters the inflatable chamber, thus preventing scattering of the reactants. Some implementations have a reaction chamber without a barrier assembly, comprising reactants that generate gas when mixed with water and an activating mechanism adapted to expose the reactants to water. A variety of manual or automatic mechanisms may be employed to activate the reaction and inflate the device.Type: GrantFiled: November 29, 2018Date of Patent: April 11, 2023Assignee: SEA-ARK TECHNOLOGIES LTD.Inventors: Matityahu Azriel, Oriya Shoham, Noam Hassidov, Moshe Shoham
