摘要： A passive fixation device, defined by a generally elongated body with proximal and distal ends, and a connecting member to connect the two, is used for the anastomosis of body lumens without sutures. The proximal and distal ends are non-deployed in a non-deployed position, and are deployed in a deployed position. While in the non-deployed positions, the passive fixation device is inserted into one or more body lumens. After insertion, both the proximal and distal ends are deployed and become expanded. One end is first deployed, and then the other. The deployed proximal end becomes retained in a first lumen, and the deployed distal end becomes retained in a second lumen. In one embodiment, the first lumen is the urethra, and the second lumen is the bladder. The two lumens are permitted to become anastomized without sutures. The passive fixation device may be made of different materials and can have coiled proximal and distal ends that are expanded to their deployed positions by a Foley catheter. Additionally, the passive fixation device can be a tightly wound coil that is self-deployed when it is advanced out of a delivery catheter. The coil can also be made of a shaped memory metal. At certain temperatures, it becomes deployed. With a change in temperature, either higher or lower, the coil collapses, and is then removed from the respective body lumen.
摘要翻译： 由具有近端和远端的大致细长的主体以及连接两者的连接构件限定的被动固定装置用于无缝线的体腔的吻合。 近端和远端未部署在非展开位置，并且部署在展开位置。 在非展开位置，被动固定装置插入一个或多个体腔。 插入后，近端和远端均展开并扩大。 一端首先部署，然后另一端。 所部署的近端保持在第一管腔中，并且所部署的远端保持在第二管腔中。 在一个实施例中，第一腔是尿道，第二腔是膀胱。 允许两个管腔在没有缝线的情况下吻合。 被动固定装置可以由不同的材料制成，并且可以具有卷绕的近端和远端，其通过Foley导管扩张到其展开位置。 此外，被动固定装置可以是紧密卷绕的线圈，当其从输送导管提前时自行展开。 线圈也可以由形状记忆金属制成。 在某些温度下，它会部署。 随着温度的变化，高或低，线圈塌陷，然后从相应的体腔移除。
