A system and method for additive manufacturing of three-dimensional structures, including three-dimensional cellular structures, are provided. The system comprises at least one print head for receiving and dispensing materials, the materials comprising a sheath fluid and a hydrogel, the print head comprising an orifice for dispensing the materials, microfluidic channels for receiving and directing the materials, fluidic switches corresponding to one of the microfluidic channels in the print head and configured to allow or disallow fluid flow in the microfluidic channels; a receiving surface for receiving a first layer of the materials dispensed from the orifice; a positioning unit for positioning the orifice of the print head in three dimensional space; and a dispensing means for dispensing the materials from the orifice of the print head.

System for additive manufacturing of three-dimensional structures and method for same

Described herein are systems, devices and methods that enable dynamic modification of the physicochemical properties of a hydrogel during its in vivo formation and delivery by a catheter. In some example embodiments, an extended endoluminal hydrogel delivery device is employed for delivering a hydrogel within a given body cavity, such as within the lumen of a blood vessel. In some example embodiments, a hydrogel precursor, as a non-viscous liquid, is injected through an intravascular catheter and crosslinking of the hydrogel precursor is initiated within a distal region of the catheter. The crosslinking process is controlled, by a control means associated with a distal region of the catheter, to control or modify one or more properties of the hydrogel. The properties may be controlled such that a hydrogel is suitable to embolize the specific target or deliver drugs or other materials beneficial to the site.

Hydrogel co-injection and real-time opto-electromagnetic modification device for tunable in-vivo delivery

Provided herein are meniscus implant compositions, as well as methods for making and using the same. The subject meniscus implants find us in repairing and/or replacing damaged or diseased meniscal tissue in a mammalian subject.

Bioprinted meniscus implant and methods of using same

A print head, system and method for producing hollow fiber structures, for example three-dimensional biological structures comprising living cells, includes a dispensing channel, a core channel converging with the proximal end of the dispensing channel, a first shell channel converging with the core channel and the dispensing channel at a focusing intersection or chamber, and a sheath flow channel converging with the dispensing channel at a sheath flow intersection or chamber located between the focusing intersection or chamber and the distal end of the dispensing channel. The diameter of the dispensing channel increases from a first diameter to a second diameter at the sheath flow intersection or chamber, and the core channel has a third diameter less than the first and second diameters. The sheath flow channel includes sheath flow sub-channels and the focusing chamber has a conical frustum shape.

Systems and methods for printing a core fiber

Provided herein are meniscus implant compositions, as well as method for making and using the same. The subject meniscus implants find use in repairing and/or replacing damaged or diseased meniscal tissue in a mammalian subject.
