Abstract
The present invention provides a deflectable needle system for use in performing diagnostic or therapeutic medical procedures. The needle assembly of the invention provides access to physiological sites which may be inaccessible by prior art needle systems due to an obstruction. The deflectable needle assembly includes a telescoping cannula, catheter and stylet. The catheter component of the assembly is curved at its distal end and axially rotatable within the lumen of the cannula providing simple maneuverability for accurate placement of the catheter at a chosen physiological site.
