Cook Medical is releasing in the United States its TriForce Peripheral Crossing Set, devices made to support percutaneous wire guides while performing interventions within the peripheral vasculature. In addition to helping to directly treat obstructions, the devices can also be used to inject radiopaque angiography contrast media to image the vasculature being worked on. The devices come in two lengths and four configurations, allowing doctors to select which are most appropriate for each case. Source
