There have been reports of detachment at the bond between the carrier capsule and the outer sheath of the Greenfield Vena Cava Filters with 12 Fr Femoral introducer Systems manufactured before Marcyh 10, 2004. If the capsule should detach during an implantation procedure, there is a risk of cardiac and pulmonary embolization.
The adjustment knob tower on one device was found to have broken off from the body of the instrument. This did not happend during a surgery and is believed to have been caused by the instrument being dropped or otherwise mishandled during hospital processing. A manufacturer evaluation of the device determined that the laser weld attaching the knob to the body was not to specification.
