LAKE OSWEGO, Ore.--(BUSINESS WIRE)--BIOTRONIK today announced the market release of two new bipolar coronary sinus leads for use in the left ventricle for cardiac resynchronization therapy (CRT). The Corox™ OTW BP and Corox™ OTW S-BP leads offer a unique design that allows them to fixate in even unusual coronary vessel anatomies, which can preclude the use of other leads. They are designed for use in patients with heart failure.
