  • Patent number: 7070722
    Abstract: A process for producing a sterile foam for medical or veterinary use is provided. A physiologically acceptable formulation for application to a body as a foam contains a foamable gelling agent. The formulation is foamed and treated with a precipitant which is calcium citrate or a calcium ion. The precipitant is combined with the foamable gelling agent before or during the foaming of the gelling agent. The foam thus obtained is allowed to cure and is then immersed in a bath of the precipitant. The treated foam is dried and sterilized by exposure to gamma-irradiation or ethylene oxide.

  • Patent number: 6447805
    Abstract: A composition suitable for implantation in soft tissue (for example at or around a body orifice) in order to augment the volume of soft tissue is produced. The particles, which are desirably irregularly shaped, are formed from a biodegradable phosphate glass, and may have an average particle diameter of 50 &mgr;m to 2000 &mgr;m, preferably 50 &mgr;m to 300 &mgr;m. The particles are used with a carrier medium for injection into soft tissue such as the bladder submucosa. This procedure can be applied to treat conditions such as vesicoureteric reflux. Additionally the procedure could be used cosmetically.

  • Patent number: 6187290
    Abstract: There is described a foamable formulation comprising a foamable carrier and an active ingredient which may be admixed with the carrier or packaged separately and dispersed into the carrier during the foaming process. Alginate gel is a preferred foamable carrier. The foam produced from such a formulation, and a foam sheet produced by drying the foam, also form part of the invention. The formulation, foam and foam sheet are especially useful for medical applications, for example in treating burns. As apparatus to store the components of the formulation and to generate the foam is also described.

  • Patent number: 6093465
    Abstract: A medical film dressing comprising a thin transparent film having a layer of skin adhesive on its front face, shielded before use by a removable cover sheet in contact which is in contact with the adhesive across the entire area of the front face, and a backing sheet detachably affixed over the whole of the rear face of said film. The dressing further comprises a flexible hinge in the form of a folded strip disposed along a peripheral edge of said thin film to conjoin said cover sheet and said backing sheet adjacent said edge, and extending around the corresponding edge of the thin film, and wherein a scoreline is formed in said cover sheet. The score line extends parallel to the edge of the dressing opposite the hinge and wherein the line of perforation extends through said thin film beneath said score line.

  • Patent number: 5972371
    Abstract: There is provided a device to promote healing of cut tissue members, such as nerves, tendon or muscles, within a body. The device is of hollow construction and comprises apertures into which the cut ends of the tissue members are placed and fixed, usually by a fibrin-based tissue glue. Located between the apertures is a substance to promote healing of the tissue member such as, for example, nerve growth factor. Optionally the device may be used in conjunction with the external reservoir of the substance and/or with a time-operated pump to deliver the substance to the device. The device is biodegradable and is preferably composed of watersoluble glass.
