Thoratec Corporation Implantable Ventricular Assist Devices (IVAD)

Class 1 Recall
Date Recall
October 19, 2007

Thoratec Corporation Implantable Ventricular Assist Devices (IVAD), Catalog Number 10012-2555-001, serial numbers 488 or higher and manufactured and distributed from October 1, 2004 through October 22, 2007.

The affected IVADs were distributed to 87 hospitals throughout the United States and other countries. The serial number is located on the label of the sterile package and on the driveline’s “Y- connector.”


An implantable ventricular assist device is a mechanical pump that helps a person’s heart that is too weak to pump blood through the body. The IVAD is designed to provide sufficient blood flow to the damaged or diseased heart. It is sometimes referred to as a “bridge to transplant” since it can help a patient survive until a heart transplant can be performed. This device is air-driven (pneumatic).


Recalling Firm:

Thoratec Corporation
6035 Stoneridge Drive
Pleasanton, California 94588


Reason for Recall:

The current Instructions for Use state that IVADs may be implanted or placed in the external position. If the IVAD is placed in the external position, air leaks may develop in the pneumatic driveline. These air leaks are a result of sharp bending of the driveline at the connection to the pump. This could result in not enough blood flow to and from the heart.

This recall does not affect implanted IVADs.

Public Contact:
Customers and patients with questions may call the company at 1-800-528-2577.
