Abstract: A device for in vivo 3D bioprinting includes an elongated hollow tube configured that can be inserted into a living body. A feed tube within the hollow tube conveys a liquid polymerizable biomaterial to an extrusion nozzle positioned at the target site. A light guide within the hollow tube conducts polymerizing light from a light source to polymerize the biomaterial that has been extruded at the target site. Arthroscopic procedures employing the device enable in vivo attachment of tissue to bone or other tissue, or replacement of loss tissue or bone volume.
