Abstract: A safety needle and blood collection and sampling system precluding needlstick injury by contaminated needles wherein a used needle is captured immediately within its carrier upon retraction of the needle flush with the carrier. Blood sampling is effected without reverse flow through the system and without reuse or exposure of a contaminated needle. Simplified means of assembling the needle are also set forth to minimize cost with maximum reliability notwithstanding a minimum of components.

Abstract: A catheter and a method of making the same, which catheter has a means for interferring with an electromagnetic field to allow accurate detection of the catheter through tissue, the catheter comprising a first tube extruded over a continuous, solid core material having a diameter equivalent to the desired diameter of the inner passageway of the catheter, bands of metal fused to the first tube at various locations, and a second tube which is extruded over the first and the metal bands. The double-walled continuous tube is then cut into individual tubes and the core material is removed to form the catheter of this invention, which has a smooth outer surface and an embedded metal band.
