    摘要： Various embodiments of the invention relate to a glaucoma valve, a casing for containing a glaucoma valve and a glaucoma drainage device comprising the glaucoma valve and/or the casing. The valve includes a flow channel having an inlet and an outlet and a valve member connected to the outlet of the flow channel. The valve member may be formed from a degradable polymer or a combination of degradable polymer and non-degradable polymer. Various embodiments of the invention relate to a glaucoma valve, the valve having a first flow channel. The interior of the first flow channel may be coated with a degradable polymer, such that in use, the polymer degrades to allow a greater flow of fluid through the flow channel. In some embodiments, the valve includes a second flow channel, which may be arranged in parallel to the first flow channel. The first flow channel may be completely sealed with the polymer such that in use, the polymer degrades to allow fluid to flow through the first flow channel. Various embodiments relate to a casing for containing a glaucoma valve. The casing may be formed from a degradable polymer, such as a biodegradable polymer.

    摘要翻译： 本发明的各种实施方案涉及青光眼瓣膜，用于容纳青光眼瓣膜的外壳和包括青光眼瓣膜和/或外壳的青光眼引流装置。 阀包括具有入口和出口的流动通道和连接到流动通道的出口的阀构件。 阀构件可以由可降解聚合物或可降解聚合物和不可降解聚合物的组合形成。 本发明的各种实施例涉及青光眼瓣膜，该瓣膜具有第一流动通道。 第一流动通道的内部可涂覆有可降解的聚合物，使得在使用中，聚合物降解以允许流体流过流动通道。 在一些实施例中，阀包括可以与第一流动通道平行布置的第二流动通道。 第一流动通道可以用聚合物完全密封，使得在使用中，聚合物降解以允许流体流过第一流动通道。 各种实施方式涉及用于容纳青光眼阀的外壳。 外壳可以由可降解的聚合物形成，例如可生物降解的聚合物。

    摘要： A bioabsorbable tracheal stent is provided. The bioabsorbable stent comprises a biodegradable polymer, wherein the “ biodegradable polymer comprises about 0 to 30 wt % glycerol, polyethylene glycol, triethyl citrate, or mixture thereof. A drug is dispersed within or dissolved in the biodegradable polymer. In a second and third aspect, the invention relates to methods of manufacturing a bioabsorbable tracheal stent. The first method includes forming a solution comprising a biodegradable polymer and a drug, the biodegradable polymer comprising about 0 to 30 wt % glycerol, polyethylene glycol, triethyl citrate, or mixture thereof. The method further comprises casting the solution to form the bioabsorbable tracheal stent. The second method includes forming a polymeric stent, and dip casting the polymeric stent in a solution comprising a biodegradable polymer and a drug to form a coating on the polymeric stent, wherein the biodegradable polymer comprises about 0 to 30 wt % glycerol, polyethylene glycol, triethyl citrate, or mixture thereof.
