  • Publication number: 20090012559
    Abstract: The present invention provides a device for occluding an anatomical aperture, such as a septal defect or patent foramen ovale (PFO). The occluder includes two sides connected by an intermediate joint. Each of the sides includes at least one elongate element, which is arranged to form non-overlapping loops. Each loop has at least one radially-extending segment that is adjacent to a radially-extending segment of another loop. In at least some embodiments, at least one pair of adjacent radially-extending segments is connected. The loops of the device may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. In some embodiments, at least one of the sides includes a tissue scaffold.

  • Publication number: 20080228218
    Abstract: The present invention provides devices for closing septal defects, such as a patent foramen ovale (PFO). The closure devices include a proximal anchor member, a distal anchor member, and at least one flexible center joint connecting the two anchor members. According to some embodiments, the proximal and/or distal anchor members may include a generally cylindrical member split along the central portion of its length to form an elongate oval. The proximal and/or distal anchor members may further include a tissue scaffold. At least some of the closure devices according to the present invention are repositionable and retrievable.

  • Publication number: 20030225421
    Abstract: The present invention provides a patent foramen ovale (PFO) closure clip. The clips of the present invention include two closure members joined by at least two spaced central connecting members. Each of the at least two spaced central connecting members is attached to each closure member at a location on the periphery of the closure member. The clips are designed such that the at least two central connecting members extend through the inclined PFO tunnel and the two closure members compress the overlapping layers of septal tissue, i.e. septum primum and septum secundum, together to close the PFO tunnel. The clips of the present invention may be formed of various materials. In at least some embodiments, the clips are formed of metals, nonmetallic materials, bioabsorbable polymers, spring steel, shape memory materials, bioabsorbable shape memory polymers, or combinations thereof.
