Abstract: According to some aspects, techniques that address one or more drawbacks of laser-based optical systems in additive fabrication devices are described. In some aspects, an additive fabrication device may include one or more variable focus lenses that may be operated (e.g., actuated) during fabrication to adjust the focus, and thereby the spot size, of a laser beam. In some aspects, an additive fabrication device may comprise a laser array, such as a plurality of vertical-cavity surface-emitting lasers (VCSELs), that may be operated to direct light into a build region, rather than using a single laser beam, such as a single diode laser. In some aspects, an additive fabrication device may comprise a container that includes a flexible display film, such as a flexible LCD screen, which may be operated to direct light into the container to thereby cure a liquid photopolymer therein.

Abstract: An implant for deployment in select locations or select tissue for regeneration of tissue is disclosed. The implant includes collagen and or other bio-resorbable materials, where the implant may also be used for therapy delivery. Additionally, the implant may include, or have blended in, an additive, such as an osteoinductive factor, for example biocompatible ceramics and glass.

Abstract: An implantable device for facilitating the healing of voids in bone, cartilage and soft tissue is disclosed. In one embodiment, the device is arranged for the local delivery of therapeutic agent. A preferred embodiment is a porous resorbable implant, wherein the therapy delivery may be localized in nature, rather than systemic, such that higher doses at the target site may be allowed than would be tolerable by the body systemically.

Abstract: Porous polymers having a plurality of openings or chambers that are highly convoluted, with each chamber being defined by multiple, thin, flat partitions are produced by a new gel enhanced phase separation technique. In a preferred embodiment, a second liquid is added to a polymer solution, the second liquid causing the solution to increase in viscosity. With sufficient polymer and second liquid present, the increase in viscosity can be up to that of a gel. The gel can then be shaped as needed. Subsequent solvent extraction leaves the porous polymeric body of defined shape. The porous polymers have utility as medical prostheses, the porosity permitting ingrowth of neighboring tissue. A second material may be incorporated into the chambers, thereby creating a microstructure filling the voids of the macrostructure.
