OCCLUSIVE MEDICAL DEVICE SYSTEM

An occlusive medical device system may include an elongate shaft having a distal strain relief portion and a lumen extending longitudinally through the elongate shaft, the elongate shaft including a plurality of retaining arms extending distally from the distal strain relief portion; an occlusive medical device including a proximal mounting portion fixed to an expandable occlusive element; and a release wire disposed within the lumen of the elongate shaft. The plurality of retaining arms may extend into the proximal mounting portion. The release wire may be configured to engage the plurality of retaining arms in a distal engagement position, thereby urging the plurality of retaining arms radially outward into releasable engagement with the proximal mounting portion. When the release wire is in a proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal mounting portion. 一种闭塞医疗装置系统可以包括细长轴，其具有远侧应变消除部分和纵向延伸通过所述细长轴的腔，所述细长轴包括从所述远侧应变消除部分向远侧延伸的多个保持臂；闭塞医
