The present disclosure provides reinforced hydrogel structures, methods of reinforcing hydrogel structures, and methods of treating ischemic disorders using the reinforced hydrogel structures.

Aspects of the disclosure relate methods and a synthetic cell delivery device for treating trauma present relative to the inner surface of a hollow organ such as an esophagus.

A stent for anastomosis of different kinds of organs includes a main body, and at least one fixing unit provided in the main body. At least a portion of the main body is inserted into one of different kinds of organs to be anastomosed with each other, and the rest of the main body is inserted into the other of the different kinds of organs. A distance between the different kinds of organs under the anastomosis is maintained by the fixing units.

The present invention relates to a porous scaffold having excellent tissue engineering properties, and a method for manufacturing same. The scaffold of the present invention can be manufactured by a simple process, and exhibits high tensile strength and biocompatibility, as well as an excellent cell engraftment rate, and thus can be useful as a support composition for various of human transplantation, for example, as a support for artificial ligaments or abdominal wall reinforcement.

Methods are disclosed for dissecting a mucosa and a submucosa from a muscularis propria from a region of an esophagus of a subject. These methods include injecting submucosally into the esophagus of the subject a pharmaceutical composition comprising an extracellular matrix (ECM) hydrogel to form a cushion between the submucosa and the underlying muscularis propria at the region of the esophagus, wherein the ECM hydrogel has the following characteristics: a) a time to 50% gelation of less than 30 minutes at a temperature of about 37° C.; b) a flow viscosity suitable for infusion into the esophagus; and c) a stiffness of about 10 to about 400 Pascal (Pa). The ECM hydrogel is not a urinary bladder ECM hydrogel.

A modular engineered tissue construct includes a plurality of fused self-assembled, scaffold-free, high-density cell aggregates. At least one cell aggregate includes a plurality of cells and a plurality of biocompatible and biodegradable nanoparticles and/or microparticles that are incorporated within the cell aggregates. The nanoparticles and/or microparticles acting as a bulking agent within the cell aggregate to increase the cell aggregate size and/or thickness and improve the mechanical properties of the cell aggregate as well as to deliver bioactive agents.

The present invention relates to a coating for a device, wherein the coating comprises a polymeric film, wherein the polymeric film comprises a polymerisation product formed from a polymerisation solution comprising dopamine, or a salt thereof, and at least one amino acid, or a salt thereof; and a metallic layer formed on the polymeric film.

The present disclosure relates to a hybrid material, such as a hybrid yarn, as well as methods of making and using the same. The hybrid material may include tropoelastin. Further, the hybrid material can also include a biodegradable polymer. In addition, the disclosure is also directed to compositions and methods for treating a tissue, such as treatment of organ prolapse.

This disclosure provides a method for improving maturation of an arteriovenous fistula (AVF) in a patient in need of hemodialysis, which method entails applying a solution to the internal wall of a lumen of an AVF; and restoring or initiating blood flow in the AVF, wherein the solution comprises an effective amount of a synthetic proteoglycan comprises a glycan having from about 1 to about 80 collagen-binding peptide(s) bonded to the glycan. Also provided are methods for preparing a vascular graft for a bypass surgery, comprising contacting the internal wall of a section of a blood vessel with a solution comprising an effective amount of the synthetic proteoglycan.

A device for treating a damaged tissue includes an expandable scaffold positionable in a portion of a luminal tissue structure of a mammal; and maintained via stent technology, wherein the scaffold is comprised of electrospun fibers composed of a biodegradable compound. The scaffold serves as a temporary template that allows the tissue to be rebuilt.
