Dual Channel Vascular Access Harness™

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

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.

Please contact Instech for pricing on quantities of 50 or more pieces, for custom configurations, or for a list of animal vendors that offer VAH and catheter installation as a surgical service.

Patent pending.
