    • The invention relates to the use of a thermal reversible gel, such as a copolymer composition, as a biological filler or implant. The gel has a semi-solid form at body temperature, but upon cooling to a temperature below a threshold level, the gel is liquefied and can be re-shaped, re-sized, manipulated or removed from the body. The gel may be used as a subcutaneous implant, a biological filler, joint or tissue spacer, for wrinkle filling or other cosmetic implants, as a soft-tissue replacement for reconstructive surgery, or as a barrier within the lumen of a biological structure, such as a blood vessel. The implant may be used to provide reversible birth control by providing, for example, a reversible barrier to the cervix or a reversible blockage of the lumen of the vas deferens.
    • 本发明涉及热可逆凝胶如共聚物组合物作为生物填料或植入物的用途。 凝胶在体温下具有半固体形式,但是当冷却到低于阈值水平时,凝胶被液化,并且可以重新成形,重新调整尺寸,操作或从身体去除。 凝胶可以用作皮肤植入物,生物填充剂,关节或组织间隔物,用于皱纹填充或其它化妆品植入物,作为用于重建手术的软组织替代物,或作为生物结构内腔内的屏障,例如 作为血管。 植入物可用于通过提供例如子宫颈的可逆屏障或输精管腔的可逆阻塞来提供可逆的节育。

    • An electrochemical reactor and process for electrolyzing a substance to change at least a portion of the substance from a first state to a second state. The reactor comprises a tubular body having a first end portion defining an opening and a second end portion defining an electrolysis chamber. The electrolysis chamber includes a well adapted to hold the substance and at least two electrodes for electrolyzing the substance in the well. The volume of the well is less than about 3 milliliters. The reactor further comprises a coupling for releasably and sealingly connecting the reactor body to an auxiliary device body. The coupling is adapted to provide a vacuum tight seal between the reactor body and the auxiliary device and to allow the reactor body to rotate about an axis of rotation independent of the auxiliary device while the reactor body is sealingly connected to the auxiliary device.

    • A method of making a polyurea—polyurethane composite structure that is substantially free from emission of volatile organic compounds is disclosed. The composite structure produced according to the method of the subject invention has a flexural modulus of at least 200,000 lb/in2. The composite structure includes first and second layers. A mold substrate is provided and a first-layer polyisocyanate component and a first-layer resin component are reacted and sprayed onto the mold substrate to form the first-layer. The first-layer polyisocyanate component includes an aliphatic polyisocyanate, and the first-layer resin component includes a polyamine thereby forming a polyurea show surface having a Shore D hardness of at least 65. After application of the first-layer, a second-layer polyisocyanate component and a second-layer resin component are reacted and sprayed behind the first-layer to form the second-layer of the composite structure. The second layer resin component more specifically includes a polyol having a theoretical functionality of at least three. The first and second layers of the composite are substantially free of VOCs.
    • 公开了制备基本上不含挥发性有机化合物的发射的聚脲 - 聚氨酯复合结构的方法。 根据本发明的方法制备的复合结构的弯曲模量至少为20万磅/英寸2。 复合结构包括第一和第二层。 提供了模具基材,并将第一层多异氰酸酯组分和第一层树脂组分反应并喷涂到模制基材上以形成第一层。 第一层多异氰酸酯组分包括脂族多异氰酸酯,并且第一层树脂组分包括多胺,从而形成肖氏D硬度至少为65的聚脲显示表面。施加第一层之后,将第二层多异氰酸酯 组分和第二层树脂组分在第一层后面反应并喷涂以形成复合结构的第二层。 第二层树脂组分更具体地包括具有至少三个理论官能度的多元醇。 复合材料的第一层和第二层基本上不含VOC。
