Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 60/680,851, filed on May 13, 2005. The disclosure of the above application is incorporated herein by reference.
- The present teachings relate to an apparatus for the correction of chest wall deformities, and more specifically to a pectus bar stabilizer.
- To correct chest wall deformities, a pectus bar may be fixedly mounted to supporting structure, typically cartilage, using a stabilizer plate, which generally includes a single plate having a recess through a central portion and apertures therein for receiving and fixedly attaching a pectus bar thereto. A pectus bar stabilizer may also include a series of apertures on distal portions for fixedly securing the stabilizer plate to the supporting structure. To remove or adjust the pectus bar, screws securing the pectus bar to the stabilizer plate must be removed. But the screws are often difficult to access and remove due to surrounding tissue or bone growth.
- A pectus bar stabilizer assembly generally includes a pectus bar, a retainer assembly, a first base part and a second base part. The first and second base parts are separable from one another to facilitate removal and combinable to define a channel therebetween. The pectus bar is received by the channel and the retainer assembly retains the pectus bar in the channel. A portion of the retainer assembly may be removed, allowing the pectus bar to be removed or adjusted.
- Further areas of applicability of the present teachings will become apparent from the detailed description provided hereinafter.
