Abstract:
1. A collapsible medical device for occluding an aperture in a body including a distal side and a proximal side, 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 collapsible medical device comprising: a distal end and a distal portion for contacting the distal side of tissue through which the aperture is present; a proximal end and a proximal portion for contacting the proximal side of tissue through which the aperture is present; a center joint adapted to extend through the aperture at an opening and being hollow in the center, the center joint engaging the distal portion and the proximal portion, and the center joint having a variable length; and a catch system for holding the collapsible medical device in the second configuration, the catch system having an adjustable catch length, the catch system including a distal threaded catch portion engaging the distal end and a proximal threaded catch portion engaging the proximal end, wherein the distal threaded catch portion comprises a proximal end that connects to a distal end of the proximal threaded catch portion, the threaded portions rotating relative to one another and cooperating through the hollow center joint to adjust the catch length, and wherein the center joint and catch system are indirectly coupled and operable to generate a balanced axially compressive force in the second configuration.
