A material includes a metallic, nanoporous structure having a plurality of nanopores having a porosity that allows passage of insulin but not IgG. The metallic nanoporous structure includes titanium, 316L stainless steel and may have a textured nano-sericeous surface. A nanoporous bicontinuous structure can be integrated with nanopores.

A composite comprising: a barrier, said barrier being configured to selectively pass water, and said barrier being degradable in the presence of water; a matrix material for disposition within said barrier, wherein said matrix material has a flowable state and a set state, and wherein said matrix material is degradable in the presence of water; and at least one reinforcing element for disposition within said barrier and integration with said matrix material, wherein said at least one reinforcing element is degradable in the presence of water, and further wherein, upon the degradation of said at least one reinforcing element in the presence of water, provides an agent for modulating the degradation rate of said matrix material in the presence of water.

A tissue derived implant is provided having a configuration which is sized and shaped to be disposed within a reservoir of a handling or storage device, the implant having one or more liquid dispersion features for enabling effective hydration of the implant when the implant is disposed in the reservoir and contacted with a biocompatible liquid. The liquid dispersion features form at least one liquid pathway which facilitates collecting and distributing the biocompatible liquid to contact the substantially the entire implant. An implant assembly is also provided which comprises a handling or storage device comprising an elongated reservoir with the tissue derived implant disposed therein. Additionally, an implant kit is provided which comprises a handling or storage device with an elongated reservoir and the tissue derived implant having an elongated configuration sized and shaped to allow the implant to be disposed in the elongated reservoir at the time of use.

Provided herein are the long-acting injection compositions of β3 adrenoreceptor agonists like mirabegron or their pharmaceutically acceptable salts or esters thereof. The present invention also relates to methods for preparing long-acting injection compositions and methods of using these dosage forms for the treatment of obesity, metabolic diseases, and other diseases as described herein. The long-acting injection compositions as per the present invention have desirable pharmaceutical technical attributes.

A system for administering biologically active substances produced by foaming techniques using compressed gases or supercritical fluids relates to a porous system containing biologically active substances. The system includes a polymer matrix of poly(D,L-lactic-co-glycolic acid) or a polymer mixture containing poly(D,L-lactic-co-glycolic acid) of an intrinsic viscosity of less than 0.5 dL/g with other biodegradable synthetic or semisynthetic polyesters, a release-regulating component (starch and derivatives), and at least one biologically active substance. The matrix is biodegradable with a solid or semisolid consistency and a homogeneous appearance. A method for producing these systems using foaming with compressed fluids, and the use for the production of implants and scaffolds having this system are also disclosed. Optionally, a porogenic agent can be used for the formation of macropores by thermal decomposition.

Ferritin or iron-based image enhancement agents identify target tissue for treatment or ablation and are heated by microwave absorption. Microwave heat substrates enhance microwave hyperthermal ablation treatment, and may be percutaneously delivered and imaged by x-ray CT during placement of the microwave treatment antenna, allowing more precise positioning and more complete ablation of a tumor site. One method of treating a target tissue uses image-guided delivery of a heat substrate with a reverse-phase change polymer, and may apply energy to fix a mass of the material in the tissue. The fixed polymer may increase hyperthermia, form a thermal boundary, or blockade a vessel or passage so as to reduce or prevent undesired conductive cooling by contiguous tissue, or may deliver a localized treatment drug at the site, upon heating or as it degrades over time.

A pellet having a convex shaped front includes a plurality of radially disposed surface slots. The concave shaped rear portion has a matching number of surface ribs that can be frictionally attached to the convex portion's slots. The pellet is constructed of a combination of medical compounds along with appropriate binders and other compounds that are pressed together under high pressure to produce a rigid mass capable of being propelled at high speeds and to pierce the skin of an animal or person where the compounds can be dissolved when contacting the internal liquid portion of the animal or person. The pellet can be loaded and propelled by a standard air rifle, gun, or pistol.

The present invention relates to a risperidone sustained release delivery system for treatment of medical conditions relating to delusional psychosis, schizophrenia, bipolar disorder, psychotic depression, obsessive-compulsion disorder, Tourette syndrome, and autistic spectrum disorders. The sustained release delivery system includes a flowable composition containing risperidone, a metabolite, or a prodrug thereof and an implant containing risperidone, a metabolite, or a prodrug thereof. The flowable composition may be infected into tissue whereupon it coagulates to become a solid or gel, monolithic implant. The flowable composition includes a biodegradable, thermoplastic polymer, an organic liquid, and risperidone, a metabolite or a prodrug thereof.

A biodegradable drug delivery compositions comprising a triblock copolymer containing a polyester and a polyethylene glycol and a diblock copolymer containing a polyester and an end-capped polyethylene glycol, as well as at least one pharmaceutically active principle or hydrophobic active principle such as medroxyprogesterone acetate, levonorgestrel, cyclosporine, progesterone or bupivacaine is disclosed.

Injectable prolonged-action compositions for use in the treatment of nail diseases, including potentially promoting the growth of the nail, or for use promoting the growth of the nail. The compositions are administered subcutaneously, and optionally as an implant. The compositions may be in solid or non-solid form and include one or more solid biodegradable sustained-release polymers, and optionally one or more active substances.
