Methods are provided for preparing liquid PRF and using the liquid PRF as a drug-delivery carrier system for other regenerative biomaterials and biomolecules. This carrier system provides more effective regenerative strategies for improved tissue wound healing, treatment, and regeneration in the body by supplying additional autologous growth factors into commonly-utilized biomaterials improving the host-tissue response to such therapies.

The invention is directed to a bone void filler comprising a scaffold or matrix. The scaffold or matrix may include a porous inorganic matrix component and/or a 3D-printed implantable device. The bone void filler may include a cellular component containing cells, some of which are capable of making extracellular matrix resembling native bone tissue. The bone void filler may include an organic matrix, such as, an organic biopolymer that aids in cell retention and renders the scaffold or matrix moldable. The bone void filler may include growth factors and/or cytokines. The bone void filler may include a clotting agent.

A composition for use in treating penile defects, including erectile dysfunction and Peyronie's disease, is provided. The composition includes adipose tissue and stem cells. The stem cells may be derived from adipose tissue. In embodiments the composition includes additional additives such as growth factors, anti-inflammatories, antioxidants, compositions useful for wound healing, and collagenases. Also provided is a method of treating a penile defect in a patient. The method includes providing a composition containing adipose tissue and stem cells, and implanting that composition into a patient in need of treatment for a penile defect. In some embodiments the patient has Peyronie's disease. In other embodiments, the patient has erectile dysfunction.

The present disclosure relates to a three-dimensional, degradable medical implant for regeneration of soft tissue comprising a plurality of volume-building components and a mesh component which is substantially made of monofilament or multifilament fibers, wherein each volume-building component is attached to at least one point on a surface of the mesh component, and wherein the projected surface area of each volume-building component, when projected on the surface of the mesh component, corresponds to a maximum of one tenth of the surface area of the mesh component.

The present invention concerns a method for obtaining an implantable cartilage gel for tissue repair of hyaline cartilage, comprising particles of chitosan hydrogel and cells that are capable of forming hyaline cartilage, said method comprising a step for amplification of primary cells in a three-dimensional structure comprising particles of physical hydrogel of chitosan or a chitosan derivative, then a step for re-differentiation and induction of the synthesis of extracellular matrix by said amplified cells, in the same three-dimensional structure, wherein said cells are primary articular chondrocytes and/or mesenchymal stem cells differentiated into chondrocytes. The present invention also concerns the cartilage gel obtained thereby, and its various uses for cartilage repair following a traumatic lesion or an osteoarticular disease such as osteoarthritis. The invention also concerns a three-dimensional matrix comprising particles of physical hydrogel of chitosan or of chitosan derivative, optionally supplemented with an anionic molecule such as hyaluronic acid or a derivative of hyaluronic acid or a complex of hyaluronic acid.

Provided herein is a delivery system, including: (a) an optical sensor configured to detect data to create a map of a patient bodily surface; and (b) a dispenser operatively associated with the optical sensor and configured to deliver compositions (optionally including cells) to the patient bodily surface based upon the data or map. Methods of forming a tissue on a patient bodily surface of a patient in need thereof are also provided, as are methods, systems and computer program products useful for processing patient bodily surface data.

The present invention relates to a three-dimensional multiphasic synthetic tissue scaffold comprising first, second and third compartments, wherein: each said compartment comprises distinct microstructural, and/or chemical, and/or mechanical properties, and is connected with at least one other compartment of the scaffold via a continuous interface; the tissue scaffold is porous; and the external morphology of the tissue scaffold mimics that of a mammalian joint or a component thereof. The invention further relates to a method for producing the three dimensional multiphasic synthetic tissue scaffold using a polymeric material, the method comprising using a three-dimensional (3D) bioprinter to print the tissue scaffold by continuously deposit the polymeric material onto a platform until the tissue scaffold is produced in its entirety.

The present disclosure relates to a three-dimensional, degradable medical implant for regeneration of soft tissue comprising a plurality of volume-building components and a mesh component which is substantially made of monofilament or multifilament fibers, wherein each volume-building component is attached to at least one point on a surface of the mesh component, and wherein the projected surface area of each volume-building component, when projected on the surface of the mesh component, corresponds to a maximum of one tenth of the surface area of the mesh component.

An embodiment includes a penile prosthetic comprising: an expandable conduit; a pump; a reservoir; a first conduit that couples the expandable conduit to the pump; a second conduit that couples the reservoir to the pump; and a plate that couples to the expandable conduit, wherein the plate includes a concave surface. Other embodiments are described herein.

This invention discloses methods and composition to form biodegradable polymer implant arrays in the live tissue. Artificial cavities are created in the live tissue by using laser ablation, oscillating needle, microneedle array and other methods. The cavities are then filled with biodegradable polymer solution. The solvent in the polymer solution is dissipated in the tissue to form a biodegradable polymer implant in artificial cavities. The cavities and implants formed are arranged to form of an array of implants. The biodegradable polymer in the cavity can also be loaded with drug to form biodegradable drug delivery array in the live tissue.
