Heart occlusion devices
View Patent ↗This disclosure is directed to an aperture occlusion device and a method for occluding an aperture, including a perimembranous ventricular septal defect. The aperture occlusion device includes a wire frame element. The wire frame forms geometric shapes that include an occluder region and a securing region. The occluder region and the securing region are separated by an attachment region including a waist. The occluder region and securing region can include membranous coverings. The device can be attached to a delivery hub. The wires forming the occluder region and securing region can have a shape-memory capability such that they can be collapsed and distorted in a sheath during delivery, but resume and maintain their intended shape after delivery.
1. An occluder device for occluding a defect in an anatomical feature, the occluder device defining a proximal end and a distal end, the occluder device comprising a plurality of wires each extending continuously between the proximal and distal ends of the device and forming a proximal disc defining a proximal outer perimeter of the device, a distal disc defining a distal outer perimeter of the device, and a waist arranged between the proximal disc and the distal disc and defining a narrowed region of the device between the proximal and distal outer perimeters, each of the plurality of wires including:
a first linear section extending radially outward from a central axis of the device toward
the proximal outer perimeter of the device,
a first curved transition extending between the first linear section and the proximal outer
perimeter of the device,
a second curved transition extending from the proximal outer perimeter of the device
toward the central axis of the device,
a central curved transition extending through the narrowed region of the device such that the narrowed region of the device is configured to extend through the defect in the anatomical feature, the plurality of wires being non-overlapping through the central axis,
a third curved transition extending from the narrowed region of the device to the distal outer perimeter of the device, the central curved transition positioned between the second and third curved transitions,
a fourth curved transition extending from the distal outer perimeter of the device toward
the central axis of the device, and
a second linear section extending radially inward from the fourth curved transition toward
the central axis of the device; and
a proximal covering arranged on the proximal disc;
a distal covering arranged on the distal disc.
2. The occluder device of claim 1 , wherein
the proximal disc comprises a substantially circular outer perimeter, and
the distal disc comprises a substantially circular outer perimeter.
3. The occluder device of claim 1 , wherein the waist comprises an open area.
4. The occluder device of claim 1 , wherein the waist comprises a greater diameter than a diameter of at least one of the proximal end and a diameter of the distal end.
5. The occluder device of claim 1 , further comprising a hub arranged at one of the proximal end and the distal end.
6. An occluder device for occluding a defect in an anatomical feature, the occluder device defining a proximal end and a distal end, the occluder device comprising a plurality of wires each extending continuously between the proximal and distal ends of the device and forming a proximal disc defining a proximal outer perimeter of the device, a distal disc defining a distal outer perimeter of the device, and a waist arranged between the proximal disc and the distal disc and defining a narrowed region of the device between the proximal and distal outer perimeters, each of the plurality of wires including:
a first linear section extending radially outward from the central axis of the device toward the proximal outer perimeter of the device,
a first curved transition extending between the first linear section and the proximal outer perimeter of the device,
a second curved transition extending from the proximal outer perimeter of the device toward the central axis of the device,
a central curved transition extending through the narrowed region of the device such that the narrowed region of the device is configured to extend through the defect in the anatomical feature, the plurality of wires being non-overlapping through the central axis,
a third curved transition extending from the narrowed region of the device to the distal outer perimeter of the device, the central curved transition positioned between the second and third curved transitions,
a fourth curved transition extending from the distal outer perimeter of the device toward the central axis of the device, and
a second linear section extending radially inward from the fourth curved transition toward the central axis of the device.
7. The occluder device of claim 6 , further comprising a covering arranged on the plurality of wires.
8. The occluder device of claim 7 , wherein the covering is configured to cover the distal disc, the proximal disc, and the waist.
9. The occluder device of claim 7 , wherein the covering is configured to stabilize the occluder device.
10. The occluder device of claim 6 , wherein each of the distal disc and the proximal disc comprise a substantially circular outer perimeter.
