model a unipolar endocardial lead

Cook Pacemaker

Summary: The Model A Unipolar Endocardial Lead is a cardiac device used in pacemaker systems to transmit electrical impulses to the heart. It is typically used by cardiologists in patients with arrhythmias.

FDA Clearance Information

Pathway 510K
Decision Date August 3, 1981
Product Code DTB
Device Class Class 3
Evidence 0 studies

This device was cleared through the FDA 510k pathway on August 3, 1981. Manufactured by Cook Pacemaker, it is classified as a Class III medical device.

What It Is

The Model A Unipolar Endocardial Lead is a component of a pacemaker system, designed to deliver electrical impulses directly to the heart muscle. It consists of a single electrode that contacts the endocardium, the inner lining of the heart. This lead is crucial for maintaining heart rhythm in patients with bradycardia or other rhythm disorders.

Clinical Applications

This lead is commonly used in cardiac electrophysiology, particularly in the implantation of pacemakers for patients with symptomatic bradycardia. It is utilized in both hospital and outpatient settings, primarily by cardiologists and electrophysiologists. The typical patient population includes those with heart block or sick sinus syndrome.

Indications for Use

The FDA indications suggest this device is used for patients requiring cardiac pacing due to arrhythmias. It is suitable for those with conditions like heart block or slow heart rates that necessitate electrical stimulation.

Practical Considerations

The unipolar design requires careful placement to ensure effective pacing. Compatibility with specific pacemaker generators should be verified. Typical sizing may vary, so clinicians should consult manufacturer guidelines for optimal fit.
