The ClearGuard HD Antimicrobial Barrier Cap is a single-use male luer lock cap that incorporates an antimicrobial treatment on its surfaces. The ClearGuard HD cap consists of 1) a polypropylene polymer plug, which has a rod extending from the luer region that is coated with the antimicrobial agent chlorhexidine acetate (CHA) and 2) a nylon lock ring with threads that are also coated with CHA. When a ClearGuard HD cap is inserted into a liquid-filled catheter, CHA elutes from the rod into the catheter lock solution. This CHA solution is designed to kill microorganisms in the hemodialysis catheter hub, which results in a reduction in Central Line-Associated Bloodstream Infection (CLABSI) rates.The ClearGuard HD Antimicrobial Barrier Cap is indicated for use with hemodialysis catheter hubs. Using in vitro methods, the antimicrobial treatment on the ClearGuard HD Antimicrobial Barrier Cap has been shown to be effective at reducing microbial colonization in hemodialysis catheter hubs against the following microorganisms: Enterococcus faecium (VRE), Enterococcus faecalis, Staphylococcus aureus, Staphylococcus epidermidis (MRSE), Pseudomonas aeruginosa, Candida albicans and Candida parapsilosis and has not been shown to be effective against Candida paratropicalis and Klebsiella pneumoniae. Using post-market clinical surveillance data, use of the ClearGuard HD Antimicrobial Barrier Cap has been shown to reduce the incidence of central-line associated bloodstream infections (CLABSI) in hemodialysis patients with catheters. The subject device is not intended to be used for the treatment of existing infections. The antimicrobial is only present within the hub of the catheter and does not migrate to distal portions of the catheter.
A sterile, implantable, flexible, double-lumen tube intended to be used for chronic or long-term (> 30 days) vascular access, primarily during haemodialysis, to conduct blood from a patient and returning it after extracorporeal circulation; it may also be used during haemoperfusion and/or apheresis. It is intended for coaxial flow of blood, may be radiopaque, coated with heparin to prevent thrombus formation, and/or include a silver-coated sleeve to retard bacterial growth; devices dedicated to catheter introduction/function (e.g., introducer needle) may be included. This is a single-use device.
