Boston Scientific Corporation has received CE Mark approval of its ACUITY® Spiral left ventricular lead for use with cardiac resynchronization therapy defibrillators and cardiac resynchronization therapy pacemakers, both of which treat heart failure.

ACUITY Spiral, features a spiral design and small lead tip profile (4 French) for placement of the lead even in difficult-to-access veins of varying sizes. A lead is an insulated wire that carries the heart signal to the implanted device and delivers energy from the device to the heart. In most cases, leads are passed into the heart through veins.
