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 side and a distal side, disposed along a longitudinal axis; an occluder portion movable between the first and second configurations; and, a catch system for holding the medical device in the second configuration including a generally tubular catch member having a central lumen disposed along the longitudinal axis with a proximal portion and a proximal end, the proximal portion having a raised portion around its outer circumference, tabs axially extending toward the raised portion along the longitudinal axis and terminating at distal tab tips, and a planar lumen intersecting the proximal end of the catch member, such that during deployment, the proximal end of the catch member is adapted to pass through an inner passageway of the occluder and to temporarily secure the device in an intermediate configuration by compression of the planar lumen and to secure the device in the second configuration when a proximal end of the device engages the raised portion, the engagement with the raised portion being secured by the tabs, wherein in the intermediate configuration the tab tips are disposed out of the central lumen, and wherein in the second configuration the tab tips are disposed in the central lumen.
