Abstract

An inflatable bone tamp for performing a minimally invasive surgical procedure includes an inner shaft that incorporates a longitudinally extensible section. The predetermined longitudinally extensible section permits greater control over the elongation of the inflatable portion of the inflatable bone tamp, thereby allowing performance characteristics to be tailored to specific procedures and/or situations. The predetermined longitudinally extensible section can be implemented in various ways, such as a spring, elastomer, or mechanical linkage, among others.

First claim

The invention claimed is:
