    • An apparatus for placement in a wound to promote healing, and a method of treating wounds using such apparatus. The apparatus comprises a bioabsorbable fabric supported by a skeleton of impervious flexible members, such as Teflon TM tubes. When placed inside the wound, the bioabsorbable fabric absorbs into the body within about 5 to 10 days. As the fabric is being absorbed, it serves as a framework for fibroblasts to bridge the gap in the wounded tissue and thereby promote healing. The tubes serve as conduits to remove excess fluids from the wound, preferably under the power of a suction device to which the tubes are connected outside the body. After the fabric is absorbed by the body, the flexible tubes are removed. An expandable embodiment may be deployed into a wound cavity via an introducer tube and plunger. The apparatus may incorporate various sensors.
    • 用于放置在伤口中以促进愈合的装置,以及使用这种装置治疗伤口的方法。 该装置包括由诸如Teflon TM管之类的不透水柔性构件骨架支撑的生物可吸收织物。 当放置在伤口内时,生物可吸收织物在约5至10天内吸收进入体内。 当织物被吸收时,其用作成纤维细胞桥接伤口组织间隙并从而促进愈合的框架。 管用作导管以从伤口除去多余的流体,优选地在吸管装置的功率下,管连接到身体外部。 在织物被身体吸收之后,去除柔性管。 可扩展的实施例可以经由导引管和柱塞部署到伤口腔中。 该装置可以结合各种传感器。

    • An ophthalmic delivery device includes a body defining a fluid reservoir and a pump in fluid communication with the reservoir. The delivery device also includes a nozzle that includes a dosage chamber for holding a dosage of fluid, a valve seat, and a valve cover. The valve cover extends about the valve seat and forms an interface therebetween and the valve seat includes an outlet aperture. The interface is in fluid communication with the outlet aperture and the dosage chamber, and at least part of the valve cover is movable between (i) a closed position with the valve cover engaging the valve seat to close the interface and form a fluid-tight seal therebetween, and (ii) an open position with at least part of the valve cover spaced away from the valve seat in response to fluid flowing through the outlet aperture at a pressure greater than a valve opening pressure to allow the passage of pressurized fluid therebetween. The valve seat and the valve cover are dimensioned to dispense the dosage of fluid through the interface at a velocity of equal to or less than 6 meters per second.
    • 眼科输送装置包括限定流体储存器的主体和与储存器流体连通的泵。 输送装置还包括喷嘴,该喷嘴包括用于保持一定量的流体的剂量室,阀座和阀盖。 阀盖围绕阀座延伸并且在它们之间形成界面,并且阀座包括出口孔。 所述界面与所述出口孔和所述剂量室流体连通,并且所述阀盖的至少一部分可在(i)与所述阀盖接合所述阀座的关闭位置之间移动以关闭所述界面并形成流体密封 密封在其间,和(ii)打开位置,其中阀盖的至少一部分响应于流体以大于阀打开压力的压力流过出口孔而与阀座间隔开,以允许加压流体在其间通过 。 阀座和阀盖的尺寸设计为以等于或小于6米/秒的速度通过界面分配流体的剂量。
