Abstract
Systems, devices and methods for treating internal tissue defects, such as septal defects, are provided. An exemplary method of treating an internal tissue defect, specifically a method of closing a patent foramen ovale (PFO), can include passing a closure element from a right atrium through a septal wall in a first location and into the left atrium. A capture device, which can be configured as a snare-like device, can be used to capture the closure element in the left atrium and pull the closure element back through the septal wall in a different, second location, such that the closure element is routed over the PFO. The closure element can then be anchored and/or locked against the septal wall such that the PFO is at least partially closed.
