FDA Clearance Information

Pathway 510K
Decision Date May 31, 1989
Product Code DTZ
Device Class Class 2
Evidence 0 studies

The device was cleared by the FDA through the 510(k) pathway on May 31, 1989. It is manufactured by Medtronic Blood Systems and classified as a Class 2 device.

What It Is

This device is an extracorporeal circuit with a bio-active surface designed to reduce blood activation and improve biocompatibility during procedures like cardiopulmonary bypass. It is intended to minimize complications associated with blood contact with foreign surfaces.

Clinical Applications

Commonly used in cardiac surgeries requiring cardiopulmonary bypass, the device helps manage patients undergoing procedures such as aortocoronary bypass grafting and ECMO support for cardiogenic shock.

Evidence Summary

The literature includes 8 studies, comprising randomized controlled trials and prospective studies, conducted between 1994 and 2003. These studies investigate the device's impact on hematological parameters and organ dysfunction markers.

Reported Outcomes

Published studies report that the device affects C5a concentration and leukocyte counts, with increased granulocytes and leukocytes observed. The device also maintains high levels of free hemoglobin in autotransfused blood, indicating its influence on blood parameters during extracorporeal circulation.

Safety Profile

Reported complications include increased levels of free hemoglobin and elevated leukocyte counts, which may indicate an inflammatory response. No severe adverse events directly attributed to the device were noted in the studies.

Evidence Limitations

The evidence is limited by small sample sizes and a focus on specific patient populations. Further research is needed to explore long-term outcomes and broader clinical applications.
