    摘要: Coatings to enhance the echogenicity of materials are especially useful for medical devices wherein the practitioner desires to locate or visualize a device by ultrasonic imaging when the device is inserted into a body cavity. These coatings can be applied to any device of virtually any composition. To accomplish this, a polymer matrix is formed containing an entrapped gas in enclosed bubbles or open surface channels or cavities. Coated needles are visible in ultrasound when inserted in animals. A pre-coat or base coat may be applied to condition the surface to enhance adhesion. A finish coat or top coat may be applied to improve durability, smoothness, and biocompatibility, lubricity, antibiotic, antimicrobial, antithrombogenic activity, and other desirable properties for the finished product. Coating liquids and methods for preparing and applying such coatings are disclosed, including forming bubbles by chemical reaction during the coating process.

    摘要翻译: 用于增强材料的回声性的涂层对于医疗装置特别有用,其中当装置插入体腔时,从业者希望通过超声成像定位或可视化装置。 这些涂层可以应用于几乎任何组成的任何装置。 为了实现这一点,形成了在封闭的气泡或开放的表面通道或空腔中含有截留气体的聚合物基质。 当插入动物时,涂层针在超声中是可见的。 可以施加预涂层或底涂层以调节表面以增强粘附性。 可以使用精加工涂层或面漆来提高成品的耐久性,光滑度和生物相容性,润滑性,抗生素,抗微生物剂,抗血栓形成活性和其它所需的性质。 公开了涂覆液体及其制备和应用方法,包括在涂覆过程中通过化学反应形成气泡。
