    • Disclosed is an improved peritoneal access system for providing repeated, long term access through the peritoneum, as for patients undergoing peritoneal dialysis. The system includes a catheter tube extending through an implantable percutaneous access device (PAD) formed of a cylindrical neck and a buttonlike annular skirt. A portion of the catheter tube external to the PAD has a bellows integrally formed therein permitting the tube to be bent and moved without restricting fluid flow or stressing the PAD. The internal portion of the catheter tube has a sharp right angle below the PAD to tunnel the tube in a subcutaneous plane to the peritoneal penetration site and a position-adjustable collar for anchoring/sealing the cathether tube near the upper surface of the peritoneum.
    • 公开了一种改进的腹膜进入系统,用于通过腹膜重复,长期进入腹膜透析患者。 该系统包括延伸穿过由圆柱形颈部和按钮状环形裙部形成的可植入经皮进入装置(PAD)的导管。 在PAD外部的导管的一部分具有一体地形成在其中的波纹管,允许管弯曲和移动,而不限制流体流动或压迫PAD。 导管的内部部分在PAD下方具有尖锐的直角,以将管子在皮下平面上穿透到腹膜穿透部位,以及位置可调套环,用于将导管固定/密封在腹膜上表面附近。
