Angiotech partner first to receive FDA approval allowing immediate MRI exams for its TAXUS(R) Express(2)(TM) paclitaxel-eluting stent system; Typical two-month wait eliminated for patients with Boston Scientific stent systems.



VANCOUVER, April 5 /PRNewswire-FirstCall/ -- Angiotech Pharmaceuticals, Inc. corporate partner Boston Scientific Corporation ("Boston") today announced that the U.S. Food and Drug Administration (FDA) has approved enhancements to the Directions for Use (DFU DFU Directions For Use

) examination immediately following implantation. The TAXUS stent system is the first drug-eluting stent to receive approval for immediate post-procedure MRI. Boston Scientific's Express(2) (bare-metal) stent system also received approval for immediate MRI exams. Patients receiving coronary stents have typically been required to wait approximately two months before receiving an MRI.

MRI is an effective method of providing detailed diagnosis for many types of injuries and conditions, including cardiovascular disease. Due to the use of intense magnetic fields in MRI examinations, implanted medical devices that contain metal may be subject to potential migration and heating within the body. As a result, DFUs for stent systems containing metal usually recommend a waiting period of approximately two months from the time of implantation until an MRI can be performed safely.

Boston Scientific performed rigorous laboratory testing to demonstrate MRI compatibility. The TAXUS Express(2) and Express(2) systems were shown to be MRI safe at a high level of magnetic field strengths with minimal effect on temperature rise and drug release.

"The FDA approval of the timing on MRI exams is a significant development for interventional cardiologists and their patients," said Paul LaViolette, Boston Scientific Chief Operating Officer Chief Operating Officer (COO)

. "Patients undergoing stent procedures can now avoid the long waiting period previously required before receiving MRI diagnostics during the most critical stage of their recovery. With our stent systems, MRI analyses can now be performed immediately."
