The present invention provides tissue sealant compositions and vasculature closure devices useful for the optical detection of tissue seal and/or clot formation. Compositions and devices of the present invention comprise optical dyes which undergo an observable change as the compositions and/or devices are incorporated into a tissue seal and/or clot, for example a change in fluorescence quantum yield and/or a change in visual color including a change in emission and/or absorption wavelength. Tissue sealants and vasculature closure devices of the present invention are useful for visualizing seal and/or clot formation, for example, during or after surgical procedures, after catheter removal, etc. The present invention further provides methods for formation and optical detection of tissue seals or vasculature puncture closures as well as medical kits useful for the formation and optical detection of tissue seals or vasculature puncture closures.
本发明提供了用于光学检测组织密封和/或凝块形成的组织密封剂组合物和血管闭合装置。本发明的组合物和装置包括光学染料,当组合物和/或装置与组织密封和/或凝块结合时,光学染料会发生可观察到的变化,例如荧光量子产率的变化和/或视觉颜色的变化,包括发射和/或吸收波长的变化。本发明的组织密封剂和血管闭合装置可用于观察密封和/或凝块的形成,例如在手术过程中或手术后、导管移除后等。本发明进一步提供了组织密封或血管穿刺闭合的形成和光学检测方法,以及用于组织密封或血管穿刺闭合的形成和光学检测的医疗包。
