Abstract:
1. An apparatus comprising: a patent foramen ovale (PFO) closure device movable from a collapsed configuration when within a delivery device to a deployed configuration for providing compressive force to a septum primum and a septum secundum, the device further comprising: a central body for extending through the PFO, wherein the central body is elongated and substantially linear and extends along a longitudinal axis of the device, a first end cap, and a second end cap in line with the central body; at least a first wire and a second wire extending through the central body from the first end cap to the second end cap; the first wire and the second wire defining a first occlusion member on a first side of the central body each wire of which extends in a substantially planar manner along the longitudinal axis of the device when in the collapsed configuration and forming a first and a second collapsible loop which are generally perpendicular to the longitudinal axis of the device and which extend in a first plane perpendicular to the central body when in the deployed configuration, and the first and second wire defining a second occlusion member on a second side of the central body, each wire of which extends in a substantially planar manner along the longitudinal axis of the device when in the collapsed configuration and forming a third and a fourth collapsible loop which are generally perpendicular to the longitudinal axis of the device and which extend in a second plane perpendicular to the central body when in the deployed configuration, wherein the first and second plane are generally parallel, wherein each collapsible loop is a single loop extending from the central body to the first or second end cap; wherein moving the first end cap toward the central body moves the first occlusion member from the collapsed configuration to the deployed configuration and moving the second end cap moves the second occlusion member from the collapsed configuration to the deployed configuration; wherein when in the deployed configuration, the first and second occlusion members each cooperate with the central body to apply a generally perpendicular force to overlapping layers of the septum primum and the septum secundum to close the PFO; wherein each of the collapsible loops is independent from one another; and wherein further, the first wire and the second wire extending through the central body from the first end cap to the second end cap extend in a substantially planar manner along the longitudinal axis of the device when in the collapsed configuration within the delivery device.
