Ink formulations for three-dimensional printing are also disclosed. Additionally, provided herein are methods for manufacturing devices and uses thereof, e.g., in treating a condition in a subject in need thereof.

Spinal Implant with a Magnesium-Phosphate Three-Dimensional Porosity Structure
20230120830 · 2023-04-20 ·

The present disclosure relates to a spinal implant for insertion between two adjacent vertebrae. The spinal implant includes a frame sized to be inserted between the two adjacent vertebrae. The spinal implant also includes a lattice structure disposed at least partially within the frame and exposed on at least one side of the frame to permit bone growth into the lattice structure. The lattice structure comprises a magnesium phosphate material.

POROUS BIOCOMPATIBLE IMPLANT WITH EXCELLENT OSSEOINTEGRATION AND METHOD FOR MANUFACTURING SAME
20230063611 · 2023-03-02 ·

The present invention relates to a porous biocompatible implant and a method for manufacturing the same, and more specifically to a porous biocompatible implant in which osseointegration is excellent, no dissociation from the implant occurs, the inflammatory response caused by metals or bacteria can be minimized, and it is possible to accelerate bone formation, while having excellent mineralized bone formation performance, and a method for manufacturing the same. In addition, the porous biocompatible implant of the present invention can be widely used in clinical practices such as dentistry and orthopedic surgery.

TREATMENT OF INTERNAL DISC DISRUPTION AND CONNECTIVE TISSUE INJURIES
20230066890 · 2023-03-02 ·

This disclosure relates to treating internal disc disruption or a connective tissue injury. The treatment involves injecting, or otherwise administering, a therapeutic composition into an animal, such as a human being, in need thereof. The therapeutic composition may contain transforming growth factor beta 1 (TGF-β1) or transforming growth factor beta 2 (TGF-β2), fibroblast growth factor (FGF), and a pharmaceutically acceptable excipient or a secondary agent.

Photo-cross-linkable shape-memory polymer and preparation method therefor
11628235 · 2023-04-18 · ·

The present invention relates to a photo-cross-linkable shape-memory polymer and a preparation method therefor. The shape-memory polymer according to one embodiment of the present invention comprises a photo-cross-linkable functional group, and thus a shape-memory polymer having a melting point suitable for a physiological or medical application device can be provided. Particularly, a method for preparing the shape-memory polymer, according to one embodiment of the present invention, uses a catalyst for inducing the simultaneous ring-opening polymerization of two monomers (CL, GMA) during synthesis of the shape-memory polymer, thereby enabling the synthesis time of the shape-memory polymer to be reduced, and shape-memory polymers having various melting points can be readily prepared by controlling the introduction amounts of CL and GMA.

COMPOSITIONS AND METHODS FOR TREATING AND PREVENTING TISSUE INJURY AND DISEASE

The present invention provides novel compositions comprising multipotent cells or microvascular tissue, wherein the cells or tissue has been sterilized and/or treated to inactivated viruses, and related methods of using these compositions to treat or prevent tissue injury or disease in an allogeneic subject.

Method for instant lumbar spine fusion

A method for instant lumbar spine fusion between two vertebrae in a patient includes establishing under X-ray fluoroscopy the location of the transpedicular notch of the next lower vertebra in caudal direction, making a percutaneous incision to the transpedicular notch, inserting a cannulated guide, drilling a transpedicular approach from the pedicle of the lower vertebra to the anterior part of the vertebral body of the vertebrae above the disc to be treated, inserting a working cannula through the previously drilled approach reaching the intervertebral disk, cleaning and scrapping the intervertebral disk space, inserting transpedicularly at least one intervertebral stabilizing screw, and acting on both intervertebral screws with screwdrivers in order to distract or contract both screws allowing to adjust or correct the intervertebral distance of the disk. The method can be performed on an outpatient basis.

IIMPROVED APPROACH TO REPAIR TISSUE DEFECTS BY BONDING INJECTABLE GELS TO NATIVE SOFT TISSUES
20230158210 · 2023-05-25 ·

Systems, methods, and kits are described for repairing a fibrocartilage defect in a subject. The fibrocartilage defect is contacted with a first composition containing an oxidized and methacrylated glycosaminoglycan to form an imine bond between the glycosaminoglycan and the fibrocartilage defect, thereby coating the fibrocartilage defect with the glycosaminoglycan. The fibrocartilage defect coated with the glycosaminoglycan is then contacted with a mixture of a pre-polymer hydrogel composition containing a first crosslinking unit that, when polymerized, is capable of bonding to methacrylate and a hydrogel polymerization initiator composition, thereby forming a hydrogel that is covalently bonded to the glycosaminoglycan through methacrylate.

Injectable collagen suspensions, the preparation method thereof, and the uses thereof, particularly for forming dense collagen matrices

Disclosed is the preparation of injectable collagen suspensions, to the method for preparing the suspensions, and to the uses thereof, particularly for forming dense collagen matrices.

Partially resorbable implants and methods

Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.
