Dual Channel Vascular Access Harness™

This new two channel VAH™ connects two independent fluid channels as simply as the standard VAH connects one. Uses include bile sampling, simultaneous infusion and blood sampling or simultaneous infusion and blood pressure measurement in rats.

Install the VAHD115AB harness at the time that the catheters are implanted. For best results use the 3Fr rounded-tip polyurethane catheters that are included with part number VAHD115AB-C. Access the ports directly using an SN22 needle for manual injections, sampling or flushing. Connect the KVAHD115T tether for continuous access to one channel through a swivel and intermittent access to the second channel through an injection port. Alternatively, connect the VAHD115T tether to a 375/D/22 swivel for continuous access to both channels. Cover the harness ports with the optional VAHD115CAP for protection while in transport or untethered.
