Abstract

The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder includes two sides connected by a central tube. In some embodiments, the occluder is formed from filaments that are joined together to define a substantially cylindrical form with openings defining struts. Upon the application of force, the struts deform into loops. The loops may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. The occluder further includes a catch system that maintains its deployed state in vivo. When the occluder is deployed in vivo, the two sides are disposed on opposite sides of the septal tissue surrounding the aperture and the catch system is engaged so that the occluder closes the aperture.

Dependent claims

A device for occluding a defect in a body and having a delivery configuration and a deployed configuration, the occluder comprising:

an occluder body formed from a cut-tube and including:
a proximal end tubular portion;
a distal end tubular portion;
a central tubular portion between the proximal end tubular portion and the distal end tubular portion;
and
a first slit tube portion extending between the central tubular portion and the proximal end tubular portion and a second slit tube portion extending between the central tubular portion and the distal end tubular portion, each of the first slit tube portion and the second slit tube portion having slits extending partially between the central tubular portion and the proximal end and distal end tubular portions respectively such that slits positioned between the central tubular portion and the proximal end tubular portion have varying starting positions relative to each other and varying ending positions relative to each along a longitudinal length of the device and slits positioned between the central tubular portion and the distal end tubular portion have varying starting positions relative to each other and varying ending positions relative to each along the longitudinal length of the device and defining:
struts extending from the proximal end tubular portion and the distal end tubular portion, and the central portion, the struts being configured to form a proximal occlusive element having overlapping petals with non-circular shapes and a curved outer perimeter defining a circumference greater than a circumference of the proximal tubular portion and the distal tubular portion and a distal occlusive element having overlapping petals with non-circular shapes and a curved outer perimeter defining a circumference greater than a circumference of the proximal tubular portion and the distal tubular portion in the deployed configuration.
