Problems solved by technology
By nature of their location, the treatment of internal tissue defects is inherently difficult.
Access to a defect through invasive surgery introduces a high level of risk that can result in serious complications for the patient.
Access to the defect remotely with a catheter or equivalent device is less risky, but treatment of the defect itself is made more difficult given the limited physical abilities of the catheter.
The difficulty in accessing and treating tissue defects is compounded when the defect is found in or near a vital organ.
Occasionally, however, these foramen fail to close and create hemodynamic problems, which, in extreme cases, can ultimately prove fatal.
A PFO can pose serious health risks for the individual, including strokes and migraines.
These devices suffer from numerous shortcomings.
For instance, these devices typically involve frame structure

Embodiment Construction
[0076] Described herein are improved devices and methods for treating septal defects. For ease of discussion, the devices and methods will be described with reference to treatment of a PFO. However, it should be understood that the devices and methods can be used in treatment of any type of septal defect including ASD's, VSD's and the like, as well as PDA's or other structural cardiac or vascular defects.
[0077]FIG. 1 is a block diagram depicting a distal portion of an exemplary embodiment of a septal defect treatment system 100 configured to treat, and, preferably close, a PFO. In this embodiment, treatment system 100 includes an elongate body member101 configured for insertion into the vasculature of a patient (human or animal) having a septal defect. Body member 101 has a longitudinal axis 107, distal end 112 and can include one or more lumens 102, each of which can be configured for achieving multiple functions. Preferably, treatment system 100 includes an implantable device 103...

Abstract
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.

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application Ser. No. 10 / 847,747, filed on May 7, 2004, which is a continuation-in-part of U.S. patent application Ser. No. 10 / 734,670, filed Dec. 11, 2003, which is a division of Ser. No. 09 / 948,453, filed Sep. 7, 2001, now U.S. Pat. No. 6,702,835 and which is a continuation-in-part of Ser. No. 09 / 948,502, filed Sep. 6, 2001, now U.S. Pat. No. 6,776,784, which is fully incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates generally to systems and methods for closing internal tissue defects, and more particularly to systems and methods for closing a patent foramen ovale or other septal defect. BACKGROUND OF THE INVENTION [0003] By nature of their location, the treatment of internal tissue defects is inherently difficult. Access to a defect through invasive surgery introduces a high level of risk that can result in serious complications for th...
