发明名称 Epidural needle for spinal cord stimulation
摘要 <p>An epidural needle for implanting therapy delivery elements in an epidural space. The epidural needle includes at least an outer cannula containing an inner cannula, and a stylet located within the lumen of the inner cannula. The inner cannula substantially extends across the elongated opening at the distal end of the outer cannula to form a seal with the ligament during "loss of resistance" testing. Loss of resistance testing is performed by removing the stylet from the inner cannula. Once the epidural needle is positioned in the epidural space, the inner cannula is removed to facilitate implantation of a therapy delivery element in the epidural space.</p>
