Abstract:
1. An occluder device for occluding an opening in tissue, comprising: a first elongate body having an opening defined by a proximal end and a closed end defined by a distal end, and having an inner surface having first engaging elements defined by an alternating series of projections and indentations arranged to directly oppose each other and extend longitudinally along a lumen of the first elongate body, where a perpendicular cross-section of the alternating series of projections of the first elongate body includes a surface of each projection that is parallel to a longitudinal axis and defines a space between the projections; a first occluder pad coupled to the distal end of the first elongate body; a second elongate body having a proximal end and a distal end, and having a surface defining two elongate members that diverge away from each other as they extend from the proximal end toward the distal end of the second elongate body; each elongate member including a flange with a locking surface facing the proximal end of the second elongate body and configured to contact an opposing surface of the engaging element projections facing the distal end of the first elongate body thereby precluding the second elongate body from moving away from the distal end toward the proximal end of the first elongate body, the flange further including a compression surface having an oblique angle providing contact with the engaging element that forces the two elongate members towards each other allowing the flange to slide past engaging element projections as the second elongate body moves toward the distal end of the first elongate body responsive to a pushing force to the second elongate body; and a second occluder pad coupled to the proximal end of the second elongate body; where the device is deliverable from a single side of an opening in tissue by a single delivery catheter.
