AngioDynamics won FDA clearance for its Xcela Plus Port family with Pressure Activated Safety Valve (PASV) technology. Though the strange acronym disguises an active system that responds to increased intravenous pressure, the system doesn’t require any additional intervention from clinicians. The push-back mechanism automatically prevents blood from coming up the catheter while allowing infusion to proceed with confidence
It’s indicated for delivering contrast agents through the central line during repeat CT scans.
The PASV valve technology has more than 10 years of clinical experience with ports and PICCs. In a randomized, prospective clinical study, ports with PASV valve technology were associated with significantly less nursing time and fewer instances of poor blood return as compared to non-valved ports.i The bi-directional PASV valve is designed specifically to reduce blood reflux on the inside of the catheter and may reduce the need for heparin based care and maintenance, providing less patient risk and greater economic efficiency to the hospital.
