Systems and methods for sternum repair
The invention provides systems and methods for sternum repair. A sternum repair device may include a central body, which may include a plurality of bands and buckles, such that a band extends from the central body and is received by a buckle component. The band may wrap around the sternum and the device may be tightened to keep the separate sternum pieces together.
1. A sternotomy closure device comprising:
a first band formed of biocompatible material having at least two end portions and a mid-portion there-between, the first band having a top and bottom surface;
a second band formed of biocompatible material having at least two end portions and a mid-portion there-between, the second band having a top and bottom surface; and
a delivery needle connected to one of the end portions of each of the bands,
wherein the first and second bands each have a thickness between the top and bottom surfaces, and a width that is greater than the thickness, wherein the top or bottom surface of the first band overlies the top or bottom surface of the second band to define a common plane in an overlap region and are pivotably coupled together in the overlap region to pivot relative to one another about an axis that is perpendicular to the common plane, at least one of the bands having a buckle on one of its end portions configured to lockably receive one of the end portions of one of the bands.
2. The device of claim 1 wherein the first and second bands are pivotably coupled at the mid-portion of at least one of the bands.
3. The device of claim 1 wherein the first and second bands are pivotably coupled at the mid-portion of both of the bands.
4. The device of claim 1 wherein each of the first and second bands comprises a buckle on one of its end portions configured to lockably receive one of the end portions of one of the bands.
5. The device of claim 1 further comprising a third band having at least two end portions and a mid-portion there-between, wherein the first, second and third bands are pivotably coupled together.
6. The device of claim 1 wherein the first and second bands are pivotably coupled together by an eyelet that forms a view window through the bands.
7. The device of claim 1 wherein each of the first and second bands comprises an offset portion, each of the offset portions being configured to receive an eyelet there-through, each of the bands having a buckle on one of its end portions configured to lockably receive the other end portion of the same band such that the device forms an H shape.
8. The device of claim 1 wherein the first and second bands are pivotably coupled at a pivoting portion of each band, wherein at least one of the pivoting portions comprises at least one protrusion extending toward an opposite pivoting portion to inhibit pivoting of the bands after the device is implanted.
9. A sternotomy closure device comprising:
a first band formed of biocompatible material having at least two end portions and a mid-portion there-between, the first band having a top and bottom surface; and
a second band formed of biocompatible material having at least two end portions and a mid-portion there-between, the second band having a top and bottom surface,
wherein the first and second bands each have a thickness between the top and bottom surfaces, and a width that is greater than the thickness, wherein the top or bottom surface of the first band overlies the top or bottom surface of the second band to define a common plane in an overlap region and are pivotably coupled together in the overlap region to pivot relative to one another about an axis that is perpendicular to the common plane, at least one of the bands having a buckle on one of its end portions configured to lockably receive one of the end portions of one of the bands, wherein the first and second bands each comprise an aperture having a center point and wherein the apertures are aligned, the device further comprising an eyelet located in the apertures and configured to allow the first and second bands to pivot relative to one another about the center point of their aligned apertures.
