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.
