Abstract

1386215 Catheters W M KLINE 6 April 1973 [7 April 1972] 16531/73 Heading A5R A combined spring-guide and catheter 5 has an inner wall 6 defining the lumen of the catheter and comprising a helical spring with the coils thereof in mutual contact, and an outer wall 7 formed from an inert plastics material so applied around the helical spring that its inner surface is firmly attached thereto and its outer surface is smooth, the distal end of the outer wall extending beyond the inner wall to prevent axial elongation of the spring. The extended portion may form a tip 8 which may be perforated by a single terminal aperture 9 or by a series of circumferential apertures and may be straight or curved. For manipulation of the catheter during placement into an organ a stylette 12 may be inserted within the lumen, and proximal ends of both the catheter and stylette may be provided with removable handles. The spring 6 is of stainless steel and plastics outer wall may be of a haloginated hydrocarbon. A shortened catheter for intravenous feeding may have a terminal aperture of the full internal diameter of the tube, and this end may be square-cut or chamfered (Figs. 6 and 7, not shown).
