    • A system for effecting fluid-tight coupling and mechanical joinder between a medical device and a catheter tube. An elongated catheter connection stem attached to the medical device is received in the lumen of the catheter. A catheter securement collar is advanced proximally along the exterior of the catheter and connection stem inside the catheter into the assembled condition of the connection system, passing a locking ring on the interior of the securement collar over an enlargement on the distal end of the connection stem. Maximum catheter compression occurs at the locking ring, while a void internal of the catheter system is filled with an enlarged securement lip of catheter material. Distal of maximum catheter wall compression, the catheter traverses a tortuous path between the locking ring and the enlargement, around the shoulder of the enlargement, and along the adjacent surface of the enlargement.

    • The present invention provides a catheter for detecting and treating diseased tissue in a blood vessel or other hollow body organ. The catheter comprises an elongated tubular catheter shaft having a distal end comprising a light transmission zone. A first fiber lumen in the catheter shaft contains a diagnostic optical fiber having a distal end terminating within the light transmission zone for emitting and receiving light through the light transmission zone. A diagnostic subassembly at the proximal end and in communication with the diagnostic optical fiber processes diagnostic light for use in connection with a diagnostic method for detecting diseased tissue. A second fiber lumen can be provided in the catheter shaft for containing a treatment optical fiber for delivering treatment light from a light source at the proximal end of the catheter shaft to the light transmission zone. The treatment optical fiber has a distal end terminating within the light transmission zone for emitting light for treatment of the diseased tissue. An occlusion balloon is positioned on the distal end of the catheter shaft adjacent to the light transmission zone and in fluid communication with an inflation lumen. One or more infusion ports formed on or near the light transmission zone and in fluid communication with an infusion lumen deliver infusion fluid to the hollow body organ.
    • 本发明提供一种用于检测和治疗血管或其他中空体器官中的病变组织的导管。 导管包括细长的管状导管轴,其具有包括透光区的远端。 导管轴中的第一纤维腔包含诊断光纤,其具有端部在光透射区内的远端,用于通过透光区发射和接收光。 诊断子组件在近端处并与诊断光纤通信处理诊断光,用于与用于检测患病组织的诊断方法结合使用。 可以在导管轴上设置第二纤维腔,用于容纳用于将处理光从导管轴的近端处的光源输送到光透射区的处理光纤。 处理光纤具有终端在光透射区内的远端,用于发射用于治疗患病组织的光。 闭塞气囊位于导管轴的远端与光透射区相邻并与膨胀腔流体连通。 形成在透光区上或其附近并与输注腔流体连通的一个或多个输注端口将输注流体输送到中空身体器官。
