Abstract
An apparatus for deploying a needle within a lumen is provided. The apparatus includes a housing having a threaded bushing radially disposed therein. The bushing rigidly couples with a nose cone having a guide tip disposed at an end opposite the bushing for penetrating an arterial wall of a lumen. During operation, a user incrementally advances the bushing within the housing, thereby incrementally advancing the guide tip into the lumen. The nose cone also includes a flex guide having a slot configuration which couples with the guide tip which deploys into the lumen along with the guide tip.
