Laminate Medical Technologies has announced the completion of enrolment into the VasQ External Support US study.  The study was conducted at 17 sites across the USA and prospectively enrolled 144 male and female patients in need of an arteriovenous fistula (AVF) for haemodialysis. Both brachiocephalic and radiocephalic AVF patients were included in the study. The patients will be followed for two years with the primary endpoint of primary patency analysed at six months.

According to a press release, VasQ is designed to address both the haemodynamic and mechanical factors associated with AVF failure. The device is a nitinol external support placed around the artery and vein at the creation site that aims to optimise the transition of arterial flow to the vein while reinforcing the vessel wall against the increase in mechanical stress. VasQ patients in Europe have demonstrated increased rates of receiving a usable AVF with fewer early failures and additional procedures in multiple prospective and retrospective studies. The clinical benefits of VasQ experienced in Europe are expected to be validated in the US dialysis patient population within this fully enrolled pivotal study.

Ellen Dillavou (Duke University, Durham, USA), says: “VasQ promises to be a new standard of care for fistula creation to give my haemodialysis patients the greatest probability of success.  The device has performed as expected in my study patients so far, and I look forward to continue to utilize it once commercially available in the USA.”

Laminate CEO Tammy Gilon comments: “We are grateful to our principle investigators for their commitment to this study. The results will be an important addition to the mounting evidence supporting the benefits of VasQ to promote the usability of both forearm and upper arm fistulas.”
