CPC Class B33Y

An apparatus includes a plurality of beads each defining a first opening and a second opening, a linking assembly, and a 3D printed magnetic element housed within a first bead of the plurality of beads. The linking assembly extends through the first opening and the second opening of each bead such that the beads and the linking assembly may be arranged in an annular arrangement to form a loop around an anatomical structure in a patient. The loop moves between a contracted configuration and an expanded configuration and is magnetically biased toward the contracted configuration. The 3D printed magnetic element is housed within a first bead of the plurality of beads. The 3D printed magnetic element include a composite of magnetic granules combined to generate a magnetic field. The magnetic field is generated by the 3D printed element and is configured to contribute toward the magnetic bias.

A helical distractor, including: a distractor body having an open tubular shape including: a fixed footplate attached to a first end of the distractor body; first and second body edges; first and second key grooves in the first and second body edges, respectively; and an end cap at a second end of the distractor body; a movable foot including: body threads; a first key configured to engage the first key groove; a second key configured to engage the second key groove; and a movable footplate; an advancement screw with a threaded portion inside the distraction body, wherein the threaded portion is configured to engage the body threads of the movable foot, wherein the movable foot moves along the distractor body when the advancement screw is rotated, and wherein the distractor body is configured to cause the movable foot to rotate as it moves along the distractor body.

An electrosurgical electrode for coagulating and cutting tissue includes a main body fabricated from a conductive material, and a conductive blade extending inwardly from an inner surface of the main body. The blade has an edge configured to concentrate RF for cutting tissue.

A void occlusion device that includes a scaffold defining a plurality of voids and a reinforcement member is described. The scaffold is configured to permit the infiltration of human tissue into the plurality of voids. The reinforcement member extends through at least a portion of the scaffold and is configured to resist compressive forces exerted on the scaffold. Also described are embodiments where the void occlusion device is biocompatible, bioresorbable, elastic, and suitable for radio imaging.

Provided herein photo-reactive inks, thermal-curable materials and objects (e.g., medical implants, scaffolds, devices, etc.) made therefrom, and methods of preparation and use thereof.
