Abstract

A pectus bar assembly including a bar support and a pectus bar. The bar support can include a fastener and a fabric. A fabric can encircle a first rib and a second rib of a human ribcage. The fabric can include a first free end securable to the fastener and a second free end securable to the fastener to tension the fabric around the first rib and the second rib. The pectus bar can include an elongate body. The elongate body can include an anterior side and a posterior side opposite the anterior side. The posterior side can be supported by the bar support between the first rib and the second rib.

First claim

The invention claimed is:

1. A method for implanting a pectus bar support, the pectus bar support including a fastener secured to a to a first free end of a flexible member, the pectus bar support configured to support a pectus bar between a first rib and a second rib of a human ribcage, the method comprising:
encircling, at least partially, a first rib and a second rib with the flexible member to support the pectus bar between the first rib and the second rib;
tensioning the flexible member around the first rib and the second rib; and
securing a second free end of the flexible member to the fastener.

2. The method of claim 1 , further comprising:
providing or obtaining a base; and
providing or obtaining an insert.

3. The method of claim 2 , further comprising;
coupling the insert to the base; and
securing the flexible member to the fastener by contacting the first free end and the second free end with the insert and the base when the insert is coupled to the base.

4. The method of claim 3 , further comprising:
receiving the flexible member in a bore defined by the base.

5. The method of claim 4 , further comprising:
threadably engaging the insert into a threaded surface defined by an extension of the base, wherein the extension extends inward from a wall of the bore.

6. The method of claim 5 , further comprising:
passing the first free end and the second free end through a slot that extends through a periphery of the base and intersects the bore; and
passing the first free end and the second free end from the slot into the bore.

7. The pectus bar support of claim 4 , wherein the flexible member is comprised of fabric having a width that is smaller than a diameter of the bore of the base.

8. The pectus bar support of claim 1 , wherein the flexible member is comprised of fabric.

9. The pectus bar support of claim 1 , wherein the flexible member is comprised of at least one of polyethylene, polyester, polyamide, a titanium alloy, and a stainless-steel alloy.

10. A method for implanting a pectus bar support, the pectus bar support configured to support a pectus bar between a first rib and a second rib of a human ribcage, the method comprising:
providing or obtaining a pectus bar support including a first portion including a first free end and a second portion including a second free end;
encircling, at least partially, a first rib of a ribcage with the first portion;
connecting the first portion to the second portion;
encircling, at least partially, a second rib of the ribcage adjacent to the first rib; and
adjusting tension of the first portion and the second portion around the first rib and the second rib, respectively, using one or more of the first free end and the second free end.

11. The method of claim 10 , further comprising:
securing a connector to the first portion and the second portion.

12. The method of claim 11 , further comprising:
releasably coupling the first portion to the connector.

13. The method of claim 11 , further comprising:
releasably securing an open end of the first portion to the connector.

14. The method of claim 10 , wherein the pectus bar support comprises a sleeve coupled to the first portion and the second portion, the first free end and the second free end passing through the sleeve to create at least one loop.

15. The method of claim 14 , farther comprising:
securing a connector of the pectus bar support to the first portion and the second portion.

16. The method of claim 15 , further comprising:
releasably securing an open end of the connector to the second portion.

17. A method for implanting a pectus bar support, the pectus bar support configured to support a pectus bar between a first rib and a second rib of a human ribcage, the method comprising:
encircling, at least partially, a first end of a band around a first rib of a ribcage and a second end of the band around a second rib of the ribcage;
releasably securing a fastener secured to the second end of the band to the first end of the band; and
tensioning the band around the first rib and the second rib using the fastener.

18. The method of claim 17 , wherein the fastener comprises a buckle extending from the second end.

19. The method of claim 18 , further comprising:
receiving the first end in an aperture of the buckle; and
rotating a cam within the buckle to secure the first end to the buckle.

20. The method of claim 19 , further comprising:
receiving the cam in a slot of the band to secure the band to the buckle.
