Drug diffusing peritoneal dialysis catheter

Abstract:

A peritoneal dialysis catheter includes: a catheter tube defining a lumen for carrying peritoneal dialysis fluid to at least one aperture located at or near a distal end of the lumen; at least one cuff located along the outside of the catheter tube; an access site proximally spaced from the at least one cuff, the access site allowing an antimicrobial agent to be introduced into the catheter tube; a reservoir operable with the catheter tube and in fluid communication with the access site, the reservoir storing an amount of the antimicrobial agent received from the access site after an antimicrobial agent introducer is removed from the access site; and a delivery area of the catheter tube in fluid communication with the reservoir, the delivery area positioned so as to target delivery of the antimicrobial agent to the at least one cuff or other desired location along the catheter tube.
