Pectus bar stabilizer
View Patent ↗An assembly for surgically treating a chest-wall deformity may include an implantable stabilizer member, an implantable pectus bar and an implantable stopping member. The implantable stabilizer member may include first and second base parts and a channel defined by the first and second base parts. The stabilizer member may include first and second retaining bars extending between the first and second base parts and traversing the channel. The first and second base parts may be adapted to be secured to tissue of the chest wall. The implantable pectus bar may be receivable within the channel of the stabilizer member. The implantable stopping member may be adapted to be engaged with the pectus bar between the first and second retaining bars after the pectus bar is inserted into the channel to restrict movement of the pectus bar relative to the tissue.
1. An assembly for surgically treating a chest-wall deformity, the assembly comprising:
an implantable stabilizer member having first and second base parts and a channel defined by the first and second base parts, the stabilizer member including first and second retaining bars extending between the first and second base parts and traversing the channel, the first and second base parts adapted to be secured to tissue of the chest wall;
an implantable pectus bar receivable within the channel of the stabilizer member; and
an implantable stopping member adapted to be engaged with the pectus bar between the first and second retaining bars after the pectus bar is inserted into the channel to restrict movement of the pectus bar relative to the tissue.
2. The assembly of claim 1 , wherein the first and second retaining bars are configured to be more easily severed than the pectus bar and the first and second base parts.
3. The assembly of claim 1 , wherein movement of the pectus bar within the channel is limited by interference between the stopping member and the first and second retaining bars.
4. The assembly of claim 1 , wherein the first and second base parts and the first and second retaining bars cooperate to form a monolithic body.
5. The assembly of claim 4 , wherein the stabilizer member includes another channel that allows the first and second base parts to be separated from each other upon severing the first and second retaining bars.
6. The assembly of claim 1 , wherein the pectus bar is removable from the stabilizer member without disengaging the stopping member from the pectus bar.
7. The assembly of claim 1 , wherein the stopping member includes a body portion and a head portion, the body portion directly engaging only the pectus bar.
8. The assembly of claim 1 , wherein the stopping member engages the stabilizer member.
9. The assembly of claim 1 , wherein said stopping member is a rivet.
10. The assembly of claim 1 , wherein said stopping member is a screw.
11. The assembly of claim 1 , wherein the first and second retaining bars are substantially parallel to each other.
12. The assembly of claim 1 , wherein the stopping member is engageable with one of a plurality of apertures formed in the pectus bar.
13. An assembly for surgically treating a chest-wall deformity, the assembly comprising:
an implantable stabilizer member having a base and first and second retaining members, the base including a channel and configured to be attached to a patient's tissue, the first and second retaining bars traversing the channel;
an implantable pectus bar including an aperture and receivable within the channel between the base and the first and second retaining bars; and
an implantable fastener receivable into the aperture in the pectus bar such that at least a portion of the fastener extends between the first and second retaining bars such that interference between the fastener and the first and second retaining bars restricts movement of the pectus bar within the channel.
14. The assembly of claim 13 , wherein the first and second retaining members are configured to be more easily severed than the pectus bar and the stabilizer member.
15. The assembly of claim 13 , wherein the stabilizer member and the first and second retaining members cooperate to form a monolithic body.
16. The assembly of claim 15 , wherein the stabilizer member includes another channel that allows first and second base parts of the stabilizer member to be separated from each other upon severing the first and second retaining members.
17. The assembly of claim 13 , wherein the pectus bar is removable from the stabilizer member without disengaging the fastener from the pectus bar.
18. The assembly of claim 13 , wherein the fastener includes a body portion and a head portion, the body portion directly engaging only the pectus bar.
19. The assembly of claim 13 , wherein the fastener engages the stabilizer member.
20. The assembly of claim 13 , wherein the first and second retaining members are substantially parallel to each other.
