Abstract
A marker delivery device includes an outer cannula, an inner cannula assembly, and a push rod. The outer cannula defines a longitudinal axis and includes an outer lumen. The outer lumen extends distally along the longitudinal axis from a handle to an open outer cannula distal end. The inner cannula assembly includes an inner cannula and a grip. The inner cannula is disposed within the outer lumen and extends distally along the longitudinal axis from the grip to an open distal end. The inner cannula has a resilient portion located proximate the open distal end. The resilient portion is configured to move between a stressed configuration when engaged with the outer cannula and a relaxed configuration when disengaged with the outer cannula. The push rod is disposed within an inner lumen of the inner cannula and is configured to deploy a marker through the open distal end.
