In-situ formed intervertebral fusion device and method
An orthopedic device for implanting between adjacent vertebrae comprising: an arcuate balloon and a hardenable material within said balloon. In some embodiments, the balloon has a footprint that substantially corresponds to a perimeter of a vertebral endplate. An inflatable device is inserted through a cannula into an intervertebral space and oriented so that, upon expansion, a natural angle between vertebrae will be at least partially restored. At least one component selected from the group consisting of a load-bearing component and an osteobiologic component is directed into the inflatable device through a fluid communication means.
Polyaryletherketone artificial intervertebral disc
An intervertebral prosthesis for insertion between adjacent vertebrae, in one embodiment, includes upper and lower prosthesis plates and a movable core. The prosthesis plates and optionally the core are formed of polyaryletherketone (PAEK) for improved imaging properties. A metallic insert is provided on each of the PAEK prosthesis plates providing a bone ongrowth surface.
Biological disc graft and method for relief of lower back pain and joint pain
The invention provides a method of making a biological disc graft. In one embodiment, the biological disc graft is useful for treating back or neck pain. In one embodiment, the biological disc graft is useful for treating any joint pain. The invention also provides a method of implanting said biological disc graft in a way that is minimally invasive and less dangerous.
Absorbable permeability-modulated barrier composites and applications thereof
Absorbable barrier composites are designed for modulated gas and water permeability depending on clinical use and are formed of at least two physicochemically distinct components, one of which is a film adjoined to a knitted mesh and/or electrostatically spun, non-woven fabric. Depending on the physicochemical properties of the barrier composite, it can be used in neurological and urinogenital surgical procedures as well as tissue engineering and/or as physical barriers to prevent adhesion formation following several types of surgical procedures.
Microgel compositions
This invention relates to microgel compositions, and in particular, to gel compositions fanned by binding a plurality of individual microgel particles together. The present invention also relates to processes for the preparation of these compositions and their use for particular applications, especially medical applications such as the repair of damaged, degenerated or inappropriately formed load-beating tissue (such as, for example, intervertebral discs).
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.
Microgel Compositions
This invention relates to microgel compositions, and in particular, to gel compositions formed by binding a plurality of individual microgel particles together. The present invention also relates to processes for the preparation of these compositions and their use for particular applications, especially medical applications such as the repair of damaged, degenerated or inappropriately formed load-bearing tissue (such as, for example, intervertebral discs).
METHODS AND KITS FOR PRODUCING A FIBRIN MATRIX
Methods for producing a fibrin matrix comprising a fusion peptide are described herein. In some embodiments, the method includes providing three different components, including a first component containing fibrinogen or a fibrinogen precursor and optionally, transglutaminase or a transglutaminase precursor, a second component containing thrombin or a thrombin precursor, and a third component containing a fusion peptide. In these embodiments, neither the first component nor the second component includes the fusion peptide. In some embodiments, the first or second components are premixed with the third component. The first, second and third components are mixed to form a fibrin matrix comprising a covalently linked fusion peptide. The mixing is carried out in a time frame of not more than 5 days. A kit for producing the fibrin matrix comprising a covalently linked fusion peptide is also described herein.
YARNS AND FIBERS OF POLY(BUTYLENE SUCCINATE) AND COPOLYMERS THEREOF, AND METHODS OF USE THEREOF
Resorbable implants comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing, and the fibers may be oriented. Coverings and receptacles made from forms of poly(butylene succinate) and copolymers thereof have also been developed for use with cardiac rhythm management devices and other implantable devices. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings and receptacles are made from meshes, webs, lattices, non-wovens, films, fibers, and foams, and contain antibiotics such as rifampin and minocycline.
MANUFACTURING METHOD AND INJECTION MOLDING SYSTEM
A method for manufacturing a molded part while changing between multiple molds including a first ejecting step of opening a first mold and ejecting the molded part from the first mold, a checking step of checking the ejected molded part to determine if the molded part is acceptable, a first injecting step of closing the first mold and performing injection into the first mold, a second ejecting step of, where the ejected molded part is determined to be acceptable, changing the first mold to a second mold and ejecting the molded part from the second mold after the first injecting step, and a third ejecting step of, in a case where the molded part ejected in the first ejecting step is determined to be non-acceptable, not changing the first mold to the second mold and ejecting the molded part from the first mold.
