Attain StarFix™ Model 4195 Left Ventricular Lead
People who have abnormal heart beats, or whose heart does not beat on its own, may need an electronic device called a pacemaker or a defibrillator. Furthermore, people whose hearts have a reduced pumping ability may need a device are called cardiac resynchronization therapy (CRT) device. A CRT device is implanted surgically just under the skin in the upper chest area. This device then helps the heart beat at a regular rhythm by sending electrical signals (pacing) directly to the heart tissue through flexible wires called leads. The device may also be able to stop the heart from beating too fast. Three leads are implanted into the chambers of your heart. Two of the leads will be placed on the right side of your heart. The third lead is placed on the left side of your heart and is the lead being studied.
The purpose of this study is to evaluate the safety and efficacy of the Attain StarFixTM Model 4195 Left Ventricular (LV) Lead. This particular model lead has special characteristics that may help to better keep it in position once it is implanted into the left ventricle. It is also "steroid-eluting" which means that over time it slowly releases a small amount of medication into the heart tissue to help prevent too much swelling around the area it is implanted.
Medtronic Cardiac Rhythm and Heart Failure has indicated that access to an investigational treatment associated with this study is available outside the clinical trial.
