The present invention relates to an extrudable photocrosslinkable hydrogel comprising a biochemically modified extracellular matrix (ECM) with an electroconductive nanomaterial embedded; a photoinitiator and a solvent, the method for its preparation starting from decellularized extracellular matrices (dECMs) and its applications for preparing electroconductive scaffolds, electroconductive extrudable hydrogels for in situ defect-filling, conductive grafts, in situ or in vitro printed tissues or organs, adhesives for different tissues, or bone adhesives.

Fatty acid-based, pre-cure-derived biomaterials, methods of making the biomaterials, and methods of using them as drug delivery carriers are described. The fatty acid-derived biomaterials can be utilized alone or in combination with a medical device for the release and local delivery of one or more therapeutic agents. Methods of forming and tailoring the properties of said biomaterials and methods of using said biomaterials for treating injury in a mammal are also provided.

Embodiments of the disclosure may include a pressure sensitive hydrogel composition. The composition may include a liquid solvent, a polymer, and an acid gas. The composition may be capable of having a fluid phase in which the acid gas is dissolved in the solvent and the polymer is dissolved in the solvent, and the composition may be capable of having a gel phase in which the acid gas is not dissolved in the liquid solvent and the polymer is precipitated out of the solvent. The composition may also include a chemical compound or a pharmaceutical agent that can be released after the composition is delivered to a target tissue region.

A biological composition has a mixture of mechanically selected allogeneic biologic material derived from bone marrow. The mixture has non-whole cellular components including vesicular components and active and inactive components of biological activity, cell fragments, cellular excretions, cellular derivatives, and extracellular components. The mixture is compatible with biologic function.

A medical device such as a cannula, catheter, needle or biosensing probe includes an elongated body for penetrating, inserting and/or positioning in or through the skin of a patient. The elongated body has an outer surface that when positioned in the patient with a coefficient of friction sufficient to inhibit movement between the elongated body on the skin at the insertion site to inhibit irritation at the infusion site. A lubricious coating is provided on the elongated body to assist in penetration and/or insertion of the elongated body into the patient. The lubricious coating can be removed by a shearing action by the insertion of the elongated body into the patient and/or by absorption of the lubricious coating to expose the outer surface of the elongated member.

Absorbable composite medical devices such as surgical meshes and braided sutures, which display two or more absorption/biodegradation and breaking strength retention profiles and exhibit unique properties in different clinical settings, are made using combinations of at least two types of yarns having distinctly different physicochemical and biological properties and incorporate in the subject construct special designs to provide a range of unique properties as clinically useful implants.

The present invention relates to an extracellular matrix comprising ECM producer cells, a lysyloxidase (LOX), and bone morphogenetic protein-1 (BMP1), and its use for regulating the differentiation of mesenchymal stem cells and increasing the synthesis and/or deposit of collagen in an extracellular matrix. The present invention also relates to a method for obtaining said extracellular matrix comprising incubating cells in the presence of a composition comprising a lysyl oxidase, or a fragment thereof, and bone morphogenetic protein-1, or a fragment thereof.

A composite implant for providing simultaneous magnetic resonance imaging (MRI) and computed tomographic (CT) imaging contrast is disclosed. The composite implant is formed of a calcium compound in the form of nano or microparticles doped with a first dopant configured to provide MRI contrast and a second dopant configured to provide CT contrast. The calcium compound is loaded onto a polymer gel matrix and lyophilized to form a mass with 3-dimensionally interconnected porosity, configured to provide tissue integration and proliferation sites. Methods of forming the composite implant are also disclosed. The implant could be a scaffold or bead structured to enable treatment of human or animal patient for bone/cartilage injury or defect by implantation, with MRI and CT monitoring.
