Disclosed herein are elastic, bioresorbable encasements for medical implants, methods for making the same and uses thereof.

Methods and devices for tissue remodeling and repair of collagenous tissues, including tendons, ligaments, and bone, as well as scalable connective tissue manufacturing, are provided. Collagen fibers are assembled by extensional strain-induced flow crystallization of collagen monomers. Extensional strain also drives the fusion of already formed short collagen fibrils to produce long-range, continuous fibers. Wearable devices for controlled tissue remodeling and wound healing deliver a tissue remodeling solution to a tissue repair site. The remodeling solution, together with appropriate application of strain to the tissue remodeling site, accelerate healing, prevent injury, and reduce scar formation.

Sheet structures for regenerating damaged or diseased mammalian tissue that are formed from acellular dermal mammalian tissue. The acellular dermal mammalian tissue includes extracellular matrix (ECM) and a supplemental bioactive component. The supplemental bioactive component can comprise a nucleic acid, such as RNA, and/or a cell, such as an embryonic stem cell. The sheet structures induce angiogenesis and, thereby, regeneration of new mammalian tissue.

A method of making a bone matrix includes exposing a bone tissue to a solution including a surfactant and a protease; treating the bone tissue with an acid solution following exposing the bone tissue; and electrophoretically treating the acid treated bone tissue. A bone matrix has a DNA content of not greater than 0.1 micrograms per milligram sample and a modulus in a range of 180 kPa to 250 kPa.

This invention provides coral-based scaffolds for cartilage repair, and instruments for insertion and utilization of same within a site of cartilage repair.

A method for delivering a therapeutic agent to a tumor through a target vessel includes delivering the therapeutic agent through a lumen of a catheter which has been coated or otherwise structured to reduce the wall shear stress during delivery of the immunotherapy and by generating turbulent flow during the delivery of the therapeutic agent.

The present invention provides a method of tissue healing in a subject involving administering to the subject a pharmaceutical composition for healing tissue. The pharmaceutical composition contains: adherent cells originating from mesenchymal tissue that has been treated with a physiologically active polypeptide or an LPS; and a pharmaceutically acceptable carrier.

An extended release immunomodulatory implant operatively arranged to facilitate bone morphogenesis, including an inner portion including at least one growth factor, a first layer including at least one of one or more interleukins and capsaicin, and a second layer including an antigen operatively arranged to activate an innate immune system.

A bioink composition and a 3D bioprinted scar tissue model with the bioink composition closely replicates the physiological and architectural characteristics of naturally occurring scar tissue. The 3D bioprinted scar tissue can be used to test scar resolution treatments among others. Also provided is a method of fabricating the 3D bioprinted scar tissue along with an apparatus for bioprinting the 3D bioprinted scar tissue.

Described in several embodiments herein are injectable hydrogels that are capable of attracting one or more cells, in situ. In some embodiments, the cells are cancer cells, such as cancer stem cells. Also described herein are methods of using the injectable hydrogels to fill a cavity in a subject. Also described herein are methods of treating a cancer by injecting an injectable hydrogel in a cavity in a subject formed from resecting a tumor and applying an external stimulus to the injected injectable hydrogel or area proximate to the injected injectable hydrogel.
