    摘要： Absorbable stents and absorbable stent coatings have been developed with improved properties. These devices preferably comprise biocompatible copolymers or homopolymers of 4-hydroxybutyrate, and optionally poly-L-lactic acid and other absorbable polymers and additives. Compositions of these materials can be used to make absorbable stents that provide advantageous radial strengths, resistance to recoil and creep, can be plastically expanded on a balloon catheter, and can be deployed rapidly in vivo. Stent coatings derived from these materials provide biocompatible, uniform coatings that are ductile, and can be expanded without the coating cracking and/or delarmnating and can be used as a coating matrix for drug incorporation.

    摘要： The present invention relates to an ocular implant, particularly a glaucoma stent.It is the object of the present invention to devise an ocular implant which allows the ocular eye pressure to be regulated, i.e., to be maintained at a desired level, while preventing the flow resistance from increasing over time, for example due to fibrosis.In order to achieve this object, the ocular implant according to the invention comprises a small tube (5), the wall surface (3) of which encloses a hollow duct that is open on both sides in the longitudinal direction of the hollow duct, wherein a first opening (1) allowing ocular humor to flow in and a second opening (2) allowing the ocular humor to be discharged is provided, and wherein the wall surface (3) is formed by a liquid-tight material, and wherein at least one pressure-controlled valve (4) is disposed in the area of the wall surface (3).

    摘要： The invention relates to an electrode arrangement and a measuring device for measuring the action flow and/or the action potential of an electrically active tissue. The aim of the invention is to provide a simple and economically producible electrode for measuring action flows and/or action potentials in electrically active tissues (preferably the stapedius muscle tissue), ensuring that the electrode is fixed securely, but reversibly, in the muscle tissue and that the muscle tissue is disturbed as little as possible. The electrode arrangement according to the invention comprises a first electrode (2) and a fixing element (3), the first electrode (2) being connected to a first, long electrical line (4) and consisting of a long base body (6) comprising a first end (7) and a second end (8). The first electrical line (4) is connected to the base body (6) in the region of the second end (8) thereof, and means are provided for reversibly fixing the fixing element (3) to the first electrode (2).
