DETAILED DESCRIPTION OF THE INVENTION

[0031] In this detailed description of the present invention, the inventors have proposed uses of hyaluronic acid (HA) derived from a specific source, more particularly, from an alligator or crocodile of the reptilian family.

[0032] In North America, there are large numbers of alligators in the southern part of the United States from Florida to Louisiana. It is these particular reptiles that abundant source of hyaluronic acid molecules is found in the deep fascia layers below the hide and surrounding the muscle tissue. This layer of tissue has extraordinary lubricating properties due to vast quantities of hyaluronic acid molecules. It is this source of alligator derived HA that when combined with other materials provides unique and greatly improved medical compositions for use in a range of treatments for joints, cartilage, tendons, bones, skin, pain, and wound care to name a few.

[0033] As shown in FIG. 1A, a representative photograph of an alligator 2 with the hide 4 partially removed exposing the fascia layer 6 which is laden with HA molecules of very high quality for use in medical compositions and the underlying muscle tissue 8 which the fascia layer 6 surrounds. FIG. 1B shows a technician cutting the hide. Once the derma fascia layer is removed it is processed to recover the quantity of HA molecules. Care is taken to prevent oxidation damage during recovery.

[0034] The primary source of naturally occurring HA molecules has been rooster comb or bovine or bacterial sources. It has been confirmed that HA from different sources have the same primary structure but different molecular weight. The order of HA molecular weight (Mw) ranges from 104 to 107 Dalton. For example, HA that is isolated from bovine vitreous have a lower molecular weight in the range of 104-105 Dalton, while HA from umbilical cord and rooster comb have a higher molecular weight around 106˜107 Dalton. The present invention is directed to using the reptilian source of the alligator due in part to the enhanced molecular performance closely replicating synovial fluids with improved viscoelasticity allowing restorative effects overcoming cartilage biosynthesis and degradation, anti-inflammatory effects, and direct analgesic effects. Further value of the high molecular weight is derived from the water binding and water structuring capabilities of these molecules. The polydisperse distribution of molecular weight in HA sourced from alligator backstrap tissues has been demonstrated at (˜15-1100 kDa).

[0035] In FIG. 2, one aspect of the invention is the HA molecules 20 are set in a foam structure 22 that mimics the characteristics of a porous sponge as shown in FIG. 2. The foam structure 22 has pores or an open network of passageways 24 that can be modeled to replicate the trabecular structure of the bone. As shown in FIGS. 3A and 3B, the pores 24 can be open and interconnected or separated by thin permeable windows. When structured as a foam structure 22, the material can be enhanced by the combination of a variety of one or more materials as an admixture to the HA as a carrier, diluent or excipient. Whether structured as a foam or used directly as an oil, the alligator derived HA molecule is ideally suited to be combined to improve a variety of medical compositions. FIG. 3C shows a graph the projected pore size to surface area of the HA molecule.

[0036] Interpore Area—Low mag (1000×); High Mag (10,000), Concept: Intercalation; shape, pore in pore, ceramic in varying struts of connected matrix. Pits vs. Posts, Intervariable depth; Intervariable dome Infinitely Hierarchical Variability. Example is to expand to fill pores, and then consolidate tissue as a trabeculated living tissue.

[0037] FIG. 4 is a representative view of HA foam, hydrogel 20 combined as a formulation, additive, admixture with components such as micro and nano ceramics, i.e. hydroxyapatite, calcium phosphates, silicates, etc. 30 or DBM fibers, particulate, exosome imbued, etc. 40. For example, foamed Materials—with additives (i.e. CaCO3), Enhanced Surface Roughness—TCP, Tetra-calcium Phosphate, additive composition.

[0038] Cosmetic compositions: The principle characteristics of HA is its ability to retain water. This contributes significantly to the skin maintaining a youthful appearance. The levels of HA in the body decreases with each passing year. As the levels decrease, it adversely impacts the skin's ability to retain moisture, thus leading to inevitable wrinkles. In one aspect of the invention, the use of alligator derived hyaluronic acid supports healthy skin function. Hyaluronic acid helps reproduce healthy skin cells within a collagen matrix by increasing hydration and acting as a lubricant among the collagen matrix of the skin. Hyaluronic acid is an element of the skin's construction and weakens with age, the HA supplements with collagen help ensure ample levels stay in the skin to sustain its overall appearance and function. Accordingly, the benefits of hyaluronic acid are becoming increasingly used an effective anti-aging skin care treatment in the skin care industry. This composition employing a reptilian source greatly enhances this benefit.

[0039] Injectable compositions for pain and tissue regeneration. In one aspect of the invention, a purified source of amniotic fluid similar to or the same as described in U.S. Pat. No. 10,413,572 issued on Sep. 17, 2019 is combined with hyaluronic acid derived from alligator deep derma fascia is formed into an injectable. The teachings of U.S. Pat. No. 10,413,572 are being incorporated by reference in its entirety herein. An important aspect of this combination is the HA is an anti-inflammatory which when combined with the amnion fluid is deal for treating pain associated with arthritis, sore joints and muscle injuries. The built-in growth factors in the amnion are tissue regenerative and therefore the combination improves the performance of both.

[0040] Bone repair: The composition is particularly useful when the hyaluronic acid derived form an alligator source is combined with bone regenerative materials such as bone particles, bone fibers, mineralized, demineralized, or combinations thereof. The exposure of the HA molecules is supportive of osteoinductivity. Accordingly, such combinations are very useful. In most advanced materials, biologic compositions with or without stem cells can be combined to form the composition. By way of example, materials found in both U.S. Pat. No. 9,675,643“Biologic Composition and Method of Manufacture” and U.S. Pat. No. 9,687,511 “Acellular Biologic Composition and Method of Manufacture”, which are being incorporated by reference in their entirety herein, can be combined with HA to create a bone repair material with improved properties.

[0041] Spinal Disc Repair: Similarly, the composition can be ideally used in procedures for repairing damaged discs. For way of example, the HA molecules derived from alligators can be combined with nucleus pulposus in a dry powdered form as to create a composition ideally suited for repairing damaged spinal discs. The nucleus pulposus is fully described in U.S. Pat. No. 10,064,896 entitled, “Spinal Disc Regenerative Composition and Method of Manufacture and Use” which is being incorporated by reference herein in its entirety.

[0042] In yet another embodiment, the disc repair composition may include stem cells in combination with HA molecules. In U.S. Pat. No. 10,645,921 issuing May 12, 2020 entitled, “Viable Disc Regenerative Composition and Method of Manufacture and Use” which is being incorporated by reference in its entirety, the composition has HA molecules combined with dehydrated micronized nucleus pulposus and bone marrow derived mixture of components, including non-whole cellular components in a biologically compatible, polyampholyte protectant or cryoprotectant. This use of the composition would be similarly protected by the polyampholyte which creates an improved protection of the HA molecules from damage when stored for later use.

[0043] As can be seen, the use of the alligator derived HA molecules is not only compatible, but ideally suited for these compositions in a variety of treatments. New advancements have been found wherein exosomes and other acellular biological components can be made into freeze-dried compositions as is taught in co-pending patent application U.S. Ser. No. 16/710,472 entitled “Exosome Composition and Method of Manufacture” and others.

[0044] The inventors believe all these new discoveries can be effectively used in combination with the HA molecules derived from alligators without adverse effects.

[0045] Various additional benefits of HA of the present invention include: Neutral exothermic foaming, Water structuring, hydrogel capacity, Osteoconductive, Bone-like Geometric Properties, Porosity, Connectivity, Modeling, Non-toxic; Compatible pH, isotonic, non-hemolytic, Negative charge of matrix exceeding that of rooster comb or bacterial expression, Non-hemolytic, isotonic, Aqueous binder of calcium phosphates, hydroxyapatites, open foamed graft extenders, Hybrid composition with bone allografts; i.e. DBM fibers and micronized matrices, Dermal matrices; micronized, fenestrated and compressed, shaped and stamp formed in sheets, suitable for die-cutting and Evolving tension from retraction and modeling of pores, Fiber tension across pores to sustain superstructure, Osteogenesis—bone formation response to tensile forces and stretching, Osteogenesis requires a tension-dependent mechanical cue, Foams of varying sized areas display variations in surface curvature, As matrix surrounding pores dissolves, the internal surface expands in relationship to the pore radius based on a well formulated Surface Area=3.14 (pi)×4×r2, Increasing connectivity based on optimal bone formation from 250-micron through 750-micron porosity, Integrating solid based on open foam consolidation, Bone forms and models to shear; integrating aspects and assets of both tensile and compressive combination

[0046] Creating differential particle thickness and laminar distribution is also a benefit. Regarding bone, the partially demineralized tissue will be more osteogenic than the less “revealed” particles. If these are also the larger, then the surface area of the larger is exponential to the change in diameter of the particle. If the size is then exposed to stratification, or lamination, or plying, then the larger particles with more surface area are at the bottom. If the HA incorporation allows a strip on the posterior lamina/gutter for fusion, then the greater release of growth factors is near the bone, and a grade percentage of less potential more near the soft tissue surfaces. The benefit is getting bone directed regeneration mesially, and more lateral or peripheral regenerating to the soft tissues supporting them.

[0047] HA also incorporates differential buoyance and microcortical variability. The inherent variability in the 100- to 300-micron range for use with materials of many tissue types, such as cartilage, bone, dermis, spinal cord. Assuming a regular distribution of particles produced by the manufacturing, the significant portion will be in the 200-225 um range. The invention takes advantage of the difference in size as a discriminating means of separating and laminating an allogeneic tissue construct. The size of particles can be designed to define a differential stack of matrix where size becomes an extension of angular velocity. Changing radius, speed, and collection allow drying and permit the collection of particles in colloids such as hyaluronic acid. Separating by size can be achieved by vibrational separation during polymerization. Size-varying would be between 100-300 micron. Base vibration tuned to the sizing of the particles. Screen could be solid as to transmit vibrational alone. Screen could be active sieve to drop materials into standing HA polymerization to separate.

[0048] Variations in the present invention are possible in light of the description of it provided herein. While certain representative embodiments and details have been shown for the purpose of illustrating the subject invention, it will be apparent to those skilled in this art that various changes and modifications can be made therein without departing from the scope of the subject invention. It is, therefore, to be understood that changes can be made in the particular embodiments described, which will be within the full intended scope of the invention as defined by the following appended claims.
