Abstract: A catheter grip comprises a pair of members which can be folded about a hinge and pressed lightly together with one hand to hold a catheter firmly, but without damage, in a passage formed by grooves in the members and projecting portions thereof which form a tapered spigot through which the catheter extends. The grip facilitates insertion of a catheter into a vein through a peel sheath and the subsequent removal of the sheath, for which purpose the catheter is held steady by the grip with the tip of the spigot forming a seal in the lumen of the sheath while it is withdrawn over the spigot and thereby split longitudinally along its length.
