Abstract
Devices, delivery systems, and delivery techniques for an occlusion device for closure of physical anomalies, such as an atrial septal defect, a patent foramen ovale (PFO), and other septal and vascular defects are described. Specifically, an occluder with a catch member that holds the occluder in the deployed, expanded profile configuration is provided within a delivery sheath. The proximal end of the catch member includes a flap that when positioned proximal to the proximal end of the occluder holds the occluder in the expanded profile configuration. The flap is sized and formed of a material that allows the flap to deform by bending back and forth in axial and radial directions. In certain embodiments, the flap has segments divided by notches. In certain embodiments, deforming the flap in the proximal direction requires a different amount of force than deforming the flap in the distal direction.
