The flow D rec Ted catheter which possesses the hydrophilic distal end

摘要

(57) Abstract The distance part which consists of the hydrophilic material (16) the catheter itself of the air which it possesses the flow D rec Ted catheter which (4) is included (2). The hydrophilic distance part, usually the hydrogel, when hydration being done, the water approximately 80 weight % it possesses balance moisture content. The hydrophilic distance part, being soft, is flexible, but although it is substantially inelasticity, the part whose at the same time treatment is difficult (27) it passes and it makes the use of the guide wire in order to lead the catheter possible, it is sufficiently rigid, in addition the remedy medicine of the wide range the target region (32, 34 and 36) allows the fact that it is sent. Inside the catheter itself and outer part surface both parties can make lubricity by the giving of surface denaturation or secondary lubricity coat.
