The company has redesigned the Trellis peripheral infusion system to improve thrombus isolation, lytic drug delivery, and the removal of dissolved blood clot. The device enables clinicians to dissolve acute thrombus and intervene on deep vein thrombosis (DVT) before it advances to PTS.
Trellis peripheral infusion system includes an over-the-wire catheter with two occlusive balloons to close off the treatment area and block drug release to other areas of the body; an infusion zone to deliver the lytic drug; and an oscillation drive unit that disperses the drug to dissolve the clot.
According to Covidien, the redesigned Trellis system features enhanced drug delivery and increased amplitude of the dispersion wire to better distribute the drug throughout the clot.
In addition, the new system has a larger aspiration window than the previous version, which allows for better removal of the drug and the dissolved clot.
Covidien Vascular Therapies chief medical officer Mark Turco said that the company’s clinical data has demonstrated that the Trellis system’s targeted lytic delivery may reduce the risk of bleeding complications normally associated with systemic thrombolytic infusion.
"Furthermore, intervening in patients with DVT may help improve long-term outcomes in a population that can suffer significant complications if left untreated," Turco added.
Currently, the Trellis peripheral infusion system is available in the US, Europe and Canada.
