Abstract
970,645. Catheters. D. S. SHERIDAN. Jan. 4, 1961, No. 332/61. Heading A5R. A catheter of flexible waterproof material has a relatively short tapered section which increases in wall thickness as it tapers outwardly. The tapered section defines a funnel at the proximal end of the tube, the distal end having a closed tip and side ports 30. A thermoplastic strip 24, in which X-ray opaque pigment is dispersed, is embedded in the walls of the tube along its length. The width of the strip may vary in proportion to the taper or circumference of the tube. Materials used for the tube include nylon, polyester plastics, polyethylene, vinyl polymers such as vinyl chloride polymers, vinyl ester copolymers and vinylidene polymers. Specifications 970,646 and 970,647 are referred to.
