Devices and methods for the treatment of vascular abnormalities

A delivery system for deploying a medical device to a target site, the delivery system comprising:

• a medical device comprising:
• a frame and at least one patch, the frame having proximal and distal ends, the frame comprising a proximal disc at the proximal end, a distal disc at the distal end, and a connecting segment extending between the proximal end and the distal end and connecting the proximal and distal discs, wherein each of the proximal and distal discs comprise a respective plurality of lobes, wherein each lobe is defined by a peripheral strut, and wherein the at least one patch is coupled to at least one of the proximal and distal discs of the frame;
• and
• a delivery device comprising:
• a delivery catheter;
• a delivery cable within the delivery catheter and translatable with respect to the delivery catheter;
• and
• a coupling member configured to couple the medical device to the delivery cable for facilitating at least one of deployment of the medical device at the target site.

A method for closing an atrial septal defect (ASD), the method comprising:

• providing medical device comprising a frame and at least one cover, the frame having proximal and distal ends, the frame comprising a proximal disc at the proximal end, a distal disc at the distal end, and a connecting segment extending between the proximal end and the distal end and connecting the proximal and distal discs, wherein each of the proximal and distal discs comprise a respective plurality of lobes, wherein each lobe is defined by a peripheral strut, and wherein the at least one patch is coupled to at least one of the proximal and distal discs of the frame;
• advancing the medical device to the ASD using a delivery system including a catheter and a delivery cable;
• positioning the medical device relative to the ASD to occlude blood flow;
• and
• de-coupling the medical device from the delivery cable to deploy the medical device.
