The DEXTRUS pacing lead is an extendable-retractable, active fixation lead designed to provide a larger electrically-active surface area for enhanced threshold performance. The lead features a familiar feel with durable and predictable helix extension-retraction performance and an inner coil designed for predictable torque response. The DEXTRUS lead is designed for an easy lead implant experience with mapping capability, a radiopaque helix and tip extension indicator and a flexible tip designed for flexible placement options within the right atrium and right ventricle.
Chronic rhinosinusitis represents a multifactorial inflammatory disorder, rather than simply a persistent bacterial infection.  The medical management of chronic rhinosinusitis is now focused upon controlling the inflammation that predisposes patients to obstruction, reducing the incidence of infections. However, all forms of chronic rhinosinusitis are associated with impaired sinus drainage and secondary bacterial infections. Most individuals require initial antibiotics to clear any infection and intermittently afterwards to treat acute exacerbations of chronic rhinosinusitis.
