Dialock: a new vascular access device for extracorporeal renal replacement therapy. Preliminary clinical results.

Abstract
Vascular access, a vital tool for end-stage renal disease patients, remains a weak component of extracorporeal renal replacement therapy (RRT) and the first cause of morbidity. Permanent catheters proposed as an alternative to permanent AV fistulae are associated with a significant risk of infection. A subcutaneously implantable chamber connected to permanent catheter appears highly desirable to reduce such hazards.
