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 pectus bar assembly comprising:
a bar support comprising:
a fastener; and
a fabric configured to encircle a first rib and a second rib of a human ribcage, the fabric comprising:
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; and

a pectus bar comprising an elongate body, the elongate body comprising:
an anterior side; and
a posterior side opposite the anterior side, the posterior side supportable by the bar support between the first rib and the second rib.

2. The assembly of claim 1 , the fastener comprising:
a base; and
an insert threadably coupleable to the base.

3. The assembly of claim 2 , wherein the insert is operable to compress the first free end and the second free end to the base to secure the fabric to the fastener.

4. The assembly of claim 3 , the base further comprising:
a threaded bore structured to threadably engage the insert.

5. The assembly of claim 4 , the base further comprising:
a slot extending from the threaded bore to a periphery of the base, the slot configured to receive the first free end and the second free end.

6. The assembly of claim 1 , wherein the fabric is comprised of at least one of polyethylene, polyester, polyamide, a titanium alloy, and a stainless steel alloy.

7. The assembly of claim 1 , further comprising:
a second bar support configured to be coupled to the first rib and the second rib, the second bar support structured for supporting the pectus bar.

8. A pectus bar assembly comprising:
a bar support comprising:
a first portion sized to encircle a first rib of a human ribcage;
a second portion connected to the first portion, the second portion sized to encircle a second rib of the human ribcage adjacent to the first rib; and
first and second free ends, at least one of which is adjustable to tension the first portion and the second portion around the first rib and the second rib, respectively; and

a pectus bar comprising an elongate body, the elongate body comprising:
an anterior side; and
a posterior side opposite the anterior side, the posterior side configured to be supported by the bar support between the first rib and the second rib.

9. The assembly of claim 8 , the bar support further comprising:
a connector secured to the first portion and the second portion.

10. The assembly of claim 9 , wherein the first portion is releasably coupled to the connector.

11. The assembly of claim 9 , the connector further comprising:
an open end configured to releasably secure the first portion to the connector.

12. The assembly of claim 8 , the bar support further comprising:
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.

13. The assembly of claim 8 , further comprising:
a second bar support configured to be coupled to the first rib and the second rib, the second bar support structured for supporting the pectus bar.

14. A pectus bar assembly comprising:
a bar support comprising:
a band configured to encircle a first rib of a human ribcage and a second rib of the human ribcage, the band comprising a first end and a second end opposite the first end;
a fastener coupleable to the first end, the second end releasably securable to the fastener to tension the band around the first rib and the second rib; and

a pectus bar comprising an elongate body, the elongate body comprising:
an anterior side; and
a posterior side opposite the anterior side, the posterior side supportable by the bar support between the first rib and the second rib.

15. The assembly of claim 14 , wherein the fastener comprises:
a buckle extending from the second end.

16. The assembly of claim 15 , the buckle further comprising:
an aperture configured to receive the first end; and
a cam rotatable within the buckle to secure the first end to the buckle.

17. The assembly of claim 14 , the band further comprising
a slot configured to receive the pectus bar there through.

18. The pectus bar assembly of claim 14 , further comprising:
a second bar support configured to be coupled to the first rib and the second rib, the second bar support structured for supporting the pectus bar.

19. The pectus bar assembly of claim 18 , wherein the bar support is configured to support the posterior side of the pectus bar and wherein the second bar support is configured to support the anterior side of the pectus bar.

20. The pectus bar assembly of claim 19 , wherein the band is comprised of at least one of a titanium alloy and a stainless steel alloy.
