Patent foramen ovale (PFO) closure device with radial and circumferential support
First Claim
1. A device for occluding a defect in septal tissue, comprising:
- a first side adapted to be disposed on one side of septal tissue with a defect and a second side adapted to be disposed on an opposite side of the septal tissue with a defect,an elongate center joint disposed between the first and second sides,said first and second sides adapted to occlude the defect upon deployment at the delivery location,said first and second sides each comprising a plurality of non-overlapping wires,wherein said wires form loops that extend from a center axis, the loops having inner ends proximate to the center axis and outer ends distal from the center axis, and adjacent segments of said loops are connected to each other along a generally radially extending length of the pair of adjacent segments including a point between the inner ends and the outer ends of the respective loops.

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. When the occluder is deployed in vivo, the two sides are disposed on opposite sides of the septal tissue surrounding the aperture, thereby exerting a compressive force on the septal tissue that is distributed along both the outer periphery of the occluder and the radially-extending segments.
