Impact force dampening of spring release

摘要

A delivery system (100) and spring assembly (140) are disclosed. In an embodiment, the delivery system includes a spring-loaded release mechanism (110) movable from a first position to a second position to cause withdrawal of a release wire (152) from an occlusion device (104). In an embodiment, a spring assembly includes a damper ring (180) that rotates along a helical track (148) of a bore (144) upon linear contraction of an extension spring (142) in order to dampen the spring force of the extension spring.
