    Abstract: One aspect relates to a method for producing an electrical bushing for an implantable device, a corresponding electrical bushing, and a corresponding implantable device. The method according to one embodiment is characterized in that a green blank is produced and sintered from an electrically insulating base body green blank made of a ceramic slurry or powder and at least one electrically conductive bushing body green blank made of a cermet material. The at least one bushing body green blank is inserted into a bushing opening of the base body green blank to form a composite green blank, a shape of the at least one bushing body green blank and a shape of the at least one bushing opening are complementary to each other at least in sections thereof and prevent slippage of the bushing body green blank through the bushing opening. The composite green blank is sintered while applying a force that keeps the bodies together.

  • Publication number: 20110184515
    Abstract: A device for introduction into a body in a straight configuration and assuming within the body a predefined curved configuration, includes an elongated element formed from a number of segments interconnected so as to form effective hinges therebetween. When the elongated element is confined to a straight state, the effective hinges transfer compressive forces from each segment to the next so that the elongated element can be pushed to advance it through a conduit. When the elongated element is not confined to a straight state, the effective hinges allow deflection of each segment relative to adjacent segments until abutment surfaces of the segments come into abutment, thereby defining a fully flexed state of the elongated element with a predefined curved configuration. The device can be produced with a wide range of two-dimensional and three-dimensional curved forms, and has both medical and non-medical applications.

  • Patent number: 7985781
    Abstract: The present invention provides methods of making covalently crosslinked vinyl polymer hydrogels having advantageous physical properties, and covalently crosslinked vinyl polymer hydrogel compositions made by such methods, as well as articles of manufacture comprising such covalently crosslinked vinyl polymer hydrogel compositions. The physical properties of the produced hydrogels can be adjusted by varying controlled parameters such as the proportion of physical associations, the concentration of polymer and the amount of radiation applied. Such covalently crosslinked vinyl polymer hydrogels can be made translucent, preferably transparent, or opaque depending on the processing conditions. The stability of the physical properties of the produced vinyl polymer hydrogel can be enhanced by controlling the amount of covalent crosslinks.

    Abstract: A fiber matrix is provided for maintaining space in soft tissue, for example for use in procedures for assisting drainage of aqueous humor from an eye to treat glaucoma. The fiber matrix comprises a plurality of crossing fibers forming a mesh with a plurality of void spaces. The fibers and void spaces are sized and arranged so as to permit passage of fluid through the fiber matrix and to inhibit formation of scar tissue through the fiber matrix. The fibers may comprise a polymeric material, and the fiber matrix may be manufactured by electrospinning. The fibers may comprise a biostable and/or a biodegradable material. In one method of using a fiber matrix, the fiber matrix is positioned under a scleral flap, with at least part of the fiber matrix under the scleral flap.
