Abstract:
1. A collapsible medical device for occluding an aperture in a body, the medical device having a first configuration with a reduced profile and a second configuration with an expanded profile, the medical device being adapted to be delivered through a delivery system into a desired delivery location, the medical device comprising: a proximal end, a distal end, a center joint, an axial passage along the length of the medical device; a catch member having a proximal end, a distal end, and an axial passageway, the catch member adapted to be disposed in the axial passage of the medical device such that the medical device can move from the first configuration to the second configuration with the catch member in the passage; and a delivery wire disposed within the axial passageway, the delivery wire operable to transmit a pushing force and a pulling force; wherein each of the proximal end of the medical device and the proximal end of the catch member comprises threads; wherein the proximal end of the catch member is capable of rotating relative to the proximal end of the medical device, thereby forming a threaded connection with the proximal end of the medical device; wherein the distal end of the catch member includes two apertures on the distal end for attaching the delivery wire and is operable to engage a distally disposed hook member of the delivery wire such that applying the pulling force to the delivery wire pulls the catch member proximally, and applying the pushing force to the delivery wire disconnects the delivery wire from the catch member; and wherein the pushing force and the pulling force are applied to a proximal end of the wire to pull the catch member proximally or disconnect the delivery wire from the catch member.
