摘要： A catheter having features configured to provide a substantially uniform flow rate of a fluid exiting the catheter and also exhibits anti-microbial properties. The uniform flow rate features may include one or more of a flow restricting membrane or flow restricting component within an infusion section of the catheter. In other arrangements, exit holes defining the infusion section of the catheter may be configured to provide the desired uniform flow rate over the length of the infusion section. Furthermore, the catheter also includes anti-microbial properties to inhibit the growth of microbes on or within the catheter and, preferably, to inhibit microbe growth in an anatomical region surrounding the catheter. The desired anti-microbial properties may be provided by an anti-microbial layer, anti-microbial materials dispersed within the material from which components of the catheters are constructed, or a combination of anti-microbial layers and embedded anti-microbial materials. In some arrangements, one or more portions of the catheter may be bio-absorbable.

摘要： The present invention provides a catheter for the delivery of fluid medication across an anatomical region. In accordance with one embodiment, the catheter comprises an elongated tube with a plurality of exit holes along an infusion section of the catheter, and an elongated flexible porous member residing within the tube and forming an annular space between the tube and the member. In accordance with other embodiments, the catheter includes a tube having a plurality of exit holes in a side wall of the tube. The exit holes may combine to form a flow-restricting orifice of the catheter. In one particular embodiment, the catheter comprises a tube having elongated exit slots therein. In accordance with other embodiments, the catheter includes an elongated tubular member made of a porous membrane. In accordance with other embodiments, the catheter includes an elongated “weeping” tubular coil spring attached to an end of, or enclosed within, a tube.
