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.The product 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.

Speaking on this initiative, Fred Colen, Executive Vice President, Operations and Technology, Boston Scientific Cardiac Rhythm Management said "the ability to place a left ventricular lead precisely where it will stimulate the heart most effectively is a key factor in providing patients with optimal cardiac resynchronization therapy". "ACUITY Spiral has the smallest lead tip profile in the industry and offers physicians the flexibility to place the lead in veins they may have avoided in the past."
