Patent ID: 8899236

Claim:
An occlusion system comprising: a delivery catheter including an inner catheter and a core wire; an occlusion device including an expandable portion, wherein the occlusion device is coupled to the corewire with an interference fitting, and the occlusion device is abutted against the inner catheter of the delivery catheter; and a handle coupled with the delivery catheter, the handle comprising a release mechanism moveable from a first incremented position having a first labeled operation to a second incremented position having a second labeled operation, the first and second labeled operations each referring to an operation in removing the occlusion device from the delivery catheter, and wherein movement of the release mechanism from the first incremented position to the second incremented position causes: an expandable portion of the occlusion device to expand; and a corewire to withdraw from the expanded occlusion device to fully disengage the expanded occlusion device from the delivery catheter; wherein the inner catheter provides a counterforce against the occlusion device to decouple the interference fitting when the corewire is withdrawn from the expanded occlusion device to fully disengage the expanded occlusion device from the delivery catheter.
