Abstract: A method of protecting a biologically active substance against denaturation, wherein a liquid (14) containing the active substance and a matrix-forming substance are deposited on a target surface (18) and dried so as to form a solid amorphous matrix (26) with the molecules of the active substance embedded therein, wherein an ink jet printer (10) is used for depositing the liquid (14) on the target surface (16) in the form of droplets (12) having a volume small enough to cause the liquid to dry when it impinges on the target surface (16) and to be held on the target surface through adhesion.
Abstract: Improvements applied to a textile product, and more particularly wherein the improved product is a woven textile product—fabric containing bioceramic microparticles embedded into the fibers thereof with high capacity of irradiation in the infrared region, provided to be used both in humans and animals, more particularly the invention is related to a textile product containing bioceramic microparticles with high capacity of infrared irradiation which, in contact with the heat of the human body, is capable of transmitting infrared radiation in the range between 3 ?m and 14.8 ?m, preferentially in the 14.8 micron range, said infrared radiation at this wavelength being capable of regulating the blood microcirculation, as the result of its high protection, the blood microcirculation being the nervous center of human and/or animal metabolism.
Abstract: Apparatus, and methods of making and using apparatus, for inserting intraocular lenses (IOLs) are disclosed. The apparatus includes a hollow tube having an interior wall defining a hollow space through which an intraocular lens may be passed from the open space into an eye. A lubricity enhancing component is covalently bonded to the hollow tube at the interior wall in an amount effective to facilitate the passage of the intraocular lens through the hollow space. The lubricity enhancing component includes a substituent component effective to reduce hydrolysis of said lubricity enhancing component relative to an identical lubricity enhancing component without the substituent component.

Abstract: Nano scale collagen particles can be obtained from an embrittling and attrition process that reduces the size of collagen particles to the nano scale. These nano scale collagen particles have many favorable properties such as providing beneficial and enhanced properties for cell seeding and wound healing. The nano scale collagen particles can be included in biocompatible (e.g., biostable or biodegradable) compositions and are useful for wound treatment and management, as well as in cell cultures and tissue engineering implants.
Abstract: Implantable prosthesis, components of prosthesis, and methods of making same are provided. The methods generally include the steps of providing an implant shell, applying a curable fluid composition to the shell to form a coating thereon and applying a particulate component to the composition. The composition is a mixture, for example, an emulsion, containing a silicone-based elastomer dispersion and droplets of a suspended leachable agent. After the elastomer is stabilized and cured, the particulate component and leachable agent are removed, resulting in an implantable member having a porous, open-cell surface texture designed to be effective in reducing incidence of capsular formation or contraction.

Abstract: A protective coating solution, liquid, gel, or film and a method of using such a material to provide a sterile covering for fingers, hands, arms or other selected skin surface for use as a glove substitute.
Abstract: The invention relates to a method for preventing the crystallization of a pharmaceutical in a polymer film, wherein the solvent-containing coating compound, which comprises a matrix-forming polymer or polymer mixture and at least one pharmaceutical and is spread to produce the polymer film, is temporarily dried at temperatures that is at least 10° C. above the melting temperature of the pharmaceutical contained in the coating compound. The maximum temperature is thus higher than that which is required for mere drying and obviates the need for an additional, time-consuming and expensive work step.

Abstract: Methods for forming bone implants for the repair of the ends of bones at orthopedic joints, which implants have a Young's modulus close to that of human cortical bone. Substrates of dense isotropic graphite are coated overall with hard, microporous, isotropic pyrocarbon of specific character such that it can be polished to serve as an articular surface and can also securely receive an anchoring first metal layer through PVD. The first layer has a character such that, by thermal spraying a second biocompatible metal layer thereupon, fusion occurs and thereby anchors an outermost layer that is formed with a network of randomly interconnected pores and a surface character of peaks and valleys designed to promote enhanced appositional growth of cortical bone at the interface therewith.
Abstract: A method for fabricating large-area, high-quality Graphene product. Specifically, the fabrication method uses a seed layer of exfoliated Graphene in combination with a substrate and a catalyst metal layer and introduces Carbon atoms to the Graphene seed, causing growth of high-quality Graphene product. The method of the invention combines some steps of current mechanical exfoliation techniques with other steps of the CVD process and adds a new technique to the fabrication method involving seed-based catalyst of large-area Graphene product growth.
Abstract: An expandable medical device includes a plurality of elongated struts, forming a substantially cylindrical device which is expandable from a first diameter to a second diameter. A plurality of different beneficial agents may be loaded into different openings within the struts for delivery to the tissue. For treatment of conditions such as restenosis, different agents are loaded into different openings in the device to address different biological processes involved in restenosis and are delivered at different release kinetics matched to the biological process treated. The different agents may also be used to address different diseases from the same drug delivery device. In addition, anti-thrombotic agents may be affixed to at least a portion of the surfaces of the medical device for the prevention of sub-acute thrombosis. To ensure that the different agents remain affixed to the device as well as to each other, masking and de-masking processes may be utilized.

Abstract: A method of a forming a hollow, drug-eluting medical device includes utilizing a hollow wire having an outer member and a lumen of the outer member, and filling the lumen with a fluid to form a supported hollow wire. The supported hollow wire is shaped into a stent pattern. Openings are formed through the outer member. The supported hollow wire is processed to remove the fluid from the lumen of the outer member without adversely affecting the outer member, leaving the hollow wire shaped into a stent pattern. The lumen is filled with a biologically or pharmacologically active substance.
