Abstract: The invention is a catheter/needle assembly for delivery of a medicament to the subarachnoid space of a patient which includes an elongate flexible tube portion sized to fit within the bore of an epidural needle. The flexible tube portion includes a proximal end, a distal end, and a hollow bore therethrough. The assembly further includes an elongate needle portion having a distal point and a passageway therethrough. The needle portion is fit within, fixedly attached to and fluidly sealed to the bore of the tube. The needle point projects distally a distance beyond the distal end of the tube so that the distal end of the tube forms a shoulder projecting radially outwardly at the needle portion.The invention also includes a method of using the instantly invented assembly to deliver a medicament into the subarachnoid space of a patient.

Abstract: A needle shielding cushion is provided with a generally planar base wall having a plurality of filaments projecting unitarily therefrom. The base wall defines cross-sectional dimensions which are greater than the length of a needle cannula used therewith. The filaments are dimensioned and disposed to releasably engage a needle cannula therebetween. An exposed needle cannula can be urged between the filaments after usage of the needle cannula and/or between sequential uses of the needle cannula.
