  • Patent number: 11446163
    Abstract: An endplate plunger for implanting a growth-promoting tether between opposed adjacent vertebrae. The endplate plunger includes resilient arm assemblies that store potential energy when the endplate plunger is in a retracted configuration. In transitioning from the retracted configuration to a deployed configuration, the potential energy is released in a burst of kinetic energy, causing tip portions at the distal ends of the resilient arm assemblies to be thrust into the adjacent vertebrae. In some embodiments, each tip portion forms a cleft in the respective vertebral endplate and deposits the tether therein. The tether is thereby anchored directly in the clefts, without need for separately formed anchors. In some embodiments, devices and methods are disclosed to route the tether through an implanted spinal implant.

  • Patent number: 10258739
    Abstract: A mechanical driver comprising a wedge shaped member operatively coupled to a shape memory alloy such that the shape memory alloy is able to displace the wedge shaped member in an essentially linear direction. The wedge shaped member is in constant contact with a lever arranged so that it can rotate about a fixed pivot point. A piston is arranged such that it is constant contact with the lever at a point between the pivot point of the lever and the contact point between the lever and the wedge shaped member. Activation of the shape memory alloy displaces the wedge shaped member along its linear direction and this causes the lever to be deflected about its pivot point and the piston to be deflected in an essentially linear direction that is perpendicular to the linear direction of travel of the wedge shaped member.

  • Patent number: 10245026
    Abstract: The present invention relates to devices, and methods for using the devices, to create and secure a tissue fold during an endoluminal medical procedure. The devices and methods may be used for folding and securing, for example, a fundus wall onto an esophagus wall or esophageal tissue in the region of the lower esophageal sphincter (LES) to reduce the diameter of the esophagus opening in that region. One aspect of the invention includes forming the tissue fold by closing a grasping arm that is pivotably connected to an overtube that has been positioned at the juncture of the fundus wall and esophagus wall. A further aspect of the invention includes tissue clips configured to be inserted and positioned through an endoluminal device.
