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 method for connecting two tissues, comprising:
providing a connection device including:
a first band and a second band; and
a first buckle coupled to the first band and a second buckle coupled to the second band;
wherein the first band is formed of biocompatible material having at least two end portions and a mid-portion therebetween, the first band having a top and bottom surface; the second band formed of biocompatible material having at least two end portions and a mid-portion therebetween, the second band having a top and bottom surface; and
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,
wrapping the first band around the two tissues and connecting the first band to the first buckle; and
wrapping the second band around the two tissues and connecting the second band to the second buckle.
2. The method of claim 1 wherein the two tissues are bone tissue.
3. The method of claim 2 wherein the two tissues form a part of a sternum.
4. The method of claim 1 wherein the first band and the second band cross one another.
5. The method of claim 1 , further comprising a first delivery needle connected to an end portion of the first band and a second delivery needle connected to an end portion of the second band; further comprising penetrating a portion of one of the two tissues with the first delivery needle and second delivery needle.
6. A method for connecting two tissues, comprising:
providing a connection device including:
a central body;
a first band and a second band, both bands extending from the central body; and
at least one buckle coupled to the central body;
wrapping the first band around the two tissues and connecting the first band to the at least one buckle; and
wrapping the second band around the two tissues and connecting the second band to either the at least one buckle or to a second buckle coupled to the central body,
wherein the first band is formed of biocompatible material having at least two end portions and a mid-portion therebetween, the first band having a top and bottom surface; the second band formed of biocompatible material having at least two end portions and a mid-portion therebetween, 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.
7. The method of claim 6 , wherein the first and second bands are pivotably coupled at the mid-portion of at least one of the bands.
8. The method of claim 6 , wherein the first and second bands are pivotably coupled at the mid-portion of both of the bands.
9. The method of claim 6 , further comprising a third band having at least two end portions and a mid-portion therebetween, wherein the first, second and third bands are pivotably coupled together.
10. The method of claim 6 , wherein the first and second bands are pivotably coupled together by an eyelet that forms a view window through the bands.
11. The method of claim 6 , wherein each of the first and second bands comprises an offset portion, each of the offset portions being configured to receive an eyelet therethrough.
12. The method of claim 6 , 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.
13. A method for connecting two tissues, comprising:
providing a connection device including:
a first band formed of biocompatible material having at least two end portions and a mid-portion therebetween, 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 therebetween, 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; and
wherein the first and second bands are pivotably coupled together by an eyelet that forms a view window through the first and second bands,
wrapping the first band around the two tissues and connecting the first band to a first buckle; and
wrapping the second band around the two tissues and connecting the second band to a second buckle.
14. The method of claim 13 , wherein the first and second bands are pivotably coupled at the mid-portion of at least one of the bands.
15. The method of claim 13 , wherein the first and second bands are pivotably coupled at the mid-portion of both of the bands.
16. The method of claim 13 , further comprising a third band having at least two end portions and a mid-portion therebetween, wherein the first, second and third bands are pivotably coupled together.
17. The method of claim 13 , 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.
