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), Enterococus faecalis (VRE), Acinetobacter baumannii, Escherichia coli, Staphylococcus aureus (MRSA), 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. Note: CLABSI was defined as a positive blood culture (PBC) not related to an alternative source of infection per the National Healthcare Safety Network (NHSN) surveillance definition. Alternative sources were excluded if dialysis sites attributed the PBC to vascular access on the dialysis event form. The actual reduction in CLABSI rates may be less substantial as the evaluation for alternative PBC sources was not pre-specified, nor standardized between pafients and clinical sites, and supplemental data evaluating for alternative sources were not available for review. 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.

The ClearGuard HD Antimicrobial Barrier Cap (hereinafter also referred to as the ClearGuard HD 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 catheter extension line pinch clamps are used to maintain the lock solution within the catheter lumens to minimize the risk of air embolism and maintain catheter patency. These clamps, which are closed when the catheter is not in use, mechanically confine the CHA and prevent diffusion of CHA toward the catheter tip and the patient's bloodstream.

ClearGuard HD is indicated for use as an end cap for use with hemodialysis catheter hubs. The antimicrobial treatment on the ClearGuard HD has been shown to be effective at reducing microbial colonization in hemodialysis catheter hubs against the following microorganisms: Enterococcus faecium (VRE), Enterococcus faecalis (VRE), Acinetobacter baumannii, Escherichia coli, Staphylococcus aureus (MRSA), 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. The antimicrobial effectiveness was evaluated using in vitro methods and correlation between in vitro antibacterial activity and any clinical effectiveness has not been tested. It is not intended to be used for the treatment of existing infections. The antimicrobial is only effective within the hub of the catheter, and does not migrate to distal portions of the catheter.

The ClearGuard HD end cap is male lucr lock end cap that incorporates an antimicrobial treatment on its surfaces. It is designed to reduce microbial colonization within a hemodialysis catheter hub. The ClearGuard HD end cap consists of 1) a copolyester polymer plug, which has a rod extending from the luer region that is coated with the antimicrobial agent chlorhexidine actate (CHA) and 2) a nylon lock ring with threads that are also coated with CHA. When a ClearGuard HD end cap is inserted into a liquid-filled catheter, CHA clutes into the catheter lock solution. This CHA solution is designed to reduce the number of microorganisms in the hemodialysis catheter hub. The catheter extension line pinch clamps are used to maintain the lock solution within the catheter lumens and minimize the risk of air embolism. These clamps, which are closed when the catheter is not in use, mechanically confine the CHA and prevent diffusion of CHA toward the catheter tip and the patient's bloodstream.
