Covidien has introduced the Viance crossing catheter and Enteer Re-entry system in the US, European Union and other select international markets.

The new devices are designed to enable access to the distal end of a lesion and treat chronic total occlusions (CTO).

PeaceHealth St. Joseph Medical Center spokesperson David Jessup said management of lower extremity CTO remains challenging for endovascular physicians.

"Effective devices for CTO crossing and re-entry can expand the number of patients who have access to endovascular treatment of peripheral arterial disease, which may help patients avoid more invasive treatments and allow physicians to offer amputation-saving procedures," Jessup added.

Covidien peripheral vascular division vice president and general manager Brian Verrier said, "By adding these products to our market-leading peripheral portfolio, we strive to demonstrate our commitment to advancing the treatment of vascular disease worldwide by delivering innovation that achieves both clinical and economic value for our healthcare partners."
