1. An apparatus, comprising:
- a hypodermic needle having an outer sheath that has a sharp distal tip for puncturing tissue, wherein said outer sheath defines a hollow inner bore; and
an inner removable core within said hollow inner bore, wherein said core includes a sensor element for inclusion in a system that provides a user with information about the type of tissue at said distal tip.

Abstract
A sensor guided needle to be used for the delivery of medication or placement of indwelling catheters, angiocatheters, spinal or epidural catheters, central lines, arterial lines, intraneoplastic, pediatric lines. The needle is comprised of an outer metal sheath with a biocompatible inner core containing sensor or signal elements. The measurements collected by the sensors are analyzed by a control unit to determine tissue type and possibly tissue state. This information can be utilized to track the progress of the needle and determine safe placement in the patient
