Abstract: An occlusive medical device system may include an elongate shaft having a lumen extending longitudinally through a tubular body portion and a plurality of retaining arms extending distally from the tubular body portion. An occlusive medical device may include a proximal tubular mounting portion fixed to an expandable occlusive element. A release wire may be axially translatable between a distal engagement position and a proximal released position, the release wire having a distal engagement portion and a distal retention portion distal of the distal engagement portion. The distal engagement portion may be configured to engage the plurality of retaining arms in the distal engagement position, thereby urging the plurality of retaining arms into releasable engagement with the proximal tubular mounting portion, wherein when the release wire is in the proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal tubular mounting portion.

Abstract: A vascular occlusion system may include a microcatheter configured to navigate a vasculature, an elongate shaft slidably disposed within a lumen of the microcatheter, the elongate shaft having a lumen extending from a proximal end of the elongate shaft to a distal end of the elongate shaft, a plurality of occlusive medical devices releasably connected to the elongate shaft, and a release wire slidably disposed within the elongate shaft and at least a portion of each of the plurality of occlusive medical devices. The release wire secures each of the plurality of occlusive medical devices to the distal end of the elongate shaft when the release wire is disposed within at least a portion of each of the plurality of occlusive medical devices.
