Reinforced venous drainage catheter |
摘要 |
A venous catheter comprises a flexible plastic tubular body having a center lumen. A plurality of drainage openings are formed in a reinforced opening-containing section of the body. Reinforcement is embedded in the body within the reinforced opening-containing section. The reinforcement includes a series of annular ringlets each formed of a few tightly wound helical turns. The ringlets can be non-interconnected, or interconnected by a helical connecting part by forming the ringlets and connecting parts from a continuous wire. The drainage openings are disposed in spaces formed between successive ringlets. |
