International Classification:

A61B 17/34
A61B 17/02

Abstract:

In one embodiment, an expander set includes a first and second expander. The first expander includes an outer surface having a first engagement feature and a groove and the second expander includes an inside surface having a second engagement feature adapted to engage with the first engagement feature. The inside surface of the second expander is shaped to correspond to a portion of the outer surface of the first expander. Additionally, the groove on the outer surface of the first expander is sized and shaped to accommodate a rod of a retraction system such that when the first expander is advanced within the retraction system, the rod remains within the groove. When the first and second expanders are engaged with one another, they define an oblong cross-section.
