Abstract:
1. A method of sealing a passageway between a septum primum and a septum secundum in a heart, comprising: abrading the passageway; after abrading the passageway, advancing a delivery catheter into the right atrium; advancing a collapsed anchor and suture assembly out of the delivery catheter; passing the collapsed anchor and suture assembly through the tissue of the septum secundum without passing the delivery catheter through the tissue of the septum secundum by puncturing the tissue of the septum secundum with at least two tines of the collapsed anchor; after passing the collapsed anchor and suture assembly through the tissue of the septum secundum, passing the collapsed anchor and suture assembly through the tissue of the septum primum without passing the delivery catheter through the tissue of the septum primum by puncturing the tissue of the septum primum with the at least two tines; and expanding the collapsed anchor to a deployed state to secure the suture through the tissue of the septum secundum and the tissue of the septum primum by allowing the at least two tines to self-expand after passing through the tissue of the septum secundum and the tissue of the septum primum.
