A system for treating a septal defect having an implantable treatment apparatus and devices for delivering the implantable treatment apparatus and methods for treating a septal defect are provided. The implantable treatment apparatus is preferably implantable through a septal wall or portion thereof
A system for treating a septal defect having an implantable treatment apparatus and devices for delivering the implantable treatment apparatus and methods for treating a septal defect are provided. The implantable treatment apparatus is preferably implantable through a septal wall or portion thereof. The treatment system can include a flexible elongate body member, a delivery device configured to deliver the implantable apparatus, a stabilization device configured to stabilize the body member and a positioning device configured to position the delivery device in a desired location.
What is claimed is: 1. A method of treating a patent foramen ovale in septal tissue of a septal wall with a treatment system, the patent foramen ovale defined by a septum primum and a septum secundum with a tunnel separating them, and the treatment system comprising an elongate body member, an elon
What is claimed is: 1. A method of treating a patent foramen ovale in septal tissue of a septal wall with a treatment system, the patent foramen ovale defined by a septum primum and a septum secundum with a tunnel separating them, and the treatment system comprising an elongate body member, an elongate delivery device, and a grasping device comprising a rigid arm-like member with a first end pivotally coupled with the body member and a second end pivotally coupled with the delivery device by way of a hinge, wherein the body member comprises an elongate open channel extending along a length of the side of the body member proximal to the hinge, the elongate open channel being configured to receive a side of the delivery device, and the body member further comprises a lumen having an open distal end located proximal to the elongate open channel, the delivery device being slidably housed within the lumen, wherein the body member and the delivery device are each configured for insertion into the vasculature, the method comprising: moving the delivery device with respect to the body member to cause the arm-like member to pivot and move a distal region of the delivery device relatively further away from the body member; grasping opposite sides of the septum secundum with opposing surfaces of the grasping device such that the opposing surfaces are each in contact with an opposite side of the septum secundum, the opposing surfaces being non-releasably coupled to a delivery device, wherein a first one of the opposing surfaces is located on the arm-like member; piercing a hole in the septum secundum and septum primum, with a needle having a lumen which houses a closure device, while grasping the septum secundum; and deploying the closure device such that a first end of the closure device is in contact with the septum primum and a second end of the closure device is in contact with the septum secundum. 2. The method of claim 1, wherein the closure device is an implantable device configured to at least partially close the tunnel between the septum secundum and a septum primum. 3. The method of claim 2, further comprising delivering the implantable device through the hole. 4. The method of claim 1, further comprising moving the delivery device with respect to the body member to position an open distal end of the delivery device in proximity with the septal wall before piercing the hole. 5. The method of claim 4, wherein piercing the hole in the septum secundum comprises advancing the needle member out of the delivery device through the open distal end of the delivery device. 6. The method of claim 1, wherein grasping the septum secundum comprises compressing the septum secundum between the opposing surfaces. 7. The method of claim 1, wherein the hole is located in the septal wall in a location adjacent the patent foramen ovale tunnel. 8. The method of claim 1, wherein the hole is created at a predetermined distance from the limbus. 9. The method of claim 8, wherein the hole is centered with respect to a first and second sidewall of a patent foramen ovale tunnel. 10. The method of claim 1, wherein a second one of the opposing surfaces is located on the body member. 11. The method of claim 1, wherein the delivery device is pivotally coupled directly to the arm-like member. 12. The method of claim 1, wherein a second opposing surface is located on a flexible, elongate member slidably coupled with the body member. 13. The method of claim 1, wherein the delivery device comprises a rigid tubular distal tip, and wherein the second end of the arm-like member is pivotally coupled with the rigid tubular distal tip of the delivery device by way of the hinge. 14. The method of claim 1, further comprising, after moving the delivery device with respect to the body member and prior to grasping opposite sides of the septum secundum, bringing the arm-like member into contact with the septum secundum. 15. The method of claim 14, wherein the arm-like member is brought into contact with the limbus of the septum secundum. 16. The method of claim 14, further comprising, after bringing the arm-like member into contact with the septum secundum, distally advancing the delivery device with respect to the body member to grasp the septum secundum between the arm-like member and a second opposing surface. 17. The method of claim 16, further comprising, after distally advancing the delivery device with respect to the body member to grasp the septum secundum and prior to piercing a hole in the septum secundum and septum primum, distally advancing the delivery device further with respect to the body member to cause at least a portion of the distal region of the delivery device to arc outwards away from the body member. 18. The method of claim 17, wherein distally advancing the delivery device further with respect to the body member causes an open distal end of the delivery device to rotate about the hinge. 19. The method of claim 18, wherein distally advancing the delivery device further with respect to the body member causes the open distal end of the delivery device to rotate about the hinge such that the open distal end is brought into an orientation that faces the septum secundum. 20. The method of claim 18, wherein distally advancing the delivery device further with respect to the body member causes the open distal end of the delivery device to rotate with respect to the arm member about the hinge such that the needle can be advanced along an axis normal to a right atrial surface of the septum secundum. 21. The method of claim 17, wherein, prior to moving the delivery device with respect to the body member to cause the arm-like member to pivot and move a distal region of the delivery device relatively further away from the body member, a longitudinal axis of the distal region of the delivery device, measured at the distal end of the delivery device, is substantially parallel to a longitudinal axis of a distal region of the body member and is not substantially parallel to an axis normal to the surface of the septum secundum. 22. The method of claim 21, wherein distally advancing the delivery device further with respect to the body member to cause the distal region of the delivery device to arc outwards away from the body member also causes the longitudinal axis of the distal region of the delivery device to move transverse to the longitudinal axis of the distal region of the body member. 23. The method of claim 21, wherein distally advancing the delivery device further with respect to the body member to cause the distal region of the delivery device to arc outwards away from the body member also causes the longitudinal axis of the distal region of the delivery device to move approximately perpendicular to the longitudinal axis of the distal region of the body member. 24. The method of claim 21, wherein distally advancing the delivery device further with respect to the body member to cause the distal region of the delivery device to arc outwards away from the body member also causes the longitudinal axis of the distal region of the delivery device to move substantially parallel to an axis normal to the surface of the septum secundum.
