ANGIOTECH ANNOUNCES REDEMPTION OF PORTION OF SENIOR FLOATING RATE NOTES DUE 2013

Vancouver, BC, September 18, 2012—Angiotech Pharmaceuticals, Inc. (“Angiotech”) announced that on September 17, 2012, Deutsche Bank National Trust Company (the “Trustee”), issued notices of redemption on behalf of Angiotech under the applicable indentures to redeem $40,000,000 in aggregate principal amount of Angiotech’s Senior Secured Floating Rate Notes due 2013 (the “FR Notes”, CUSIP Number 034918AH5) and $22,000 in aggregate principal amount of Angiotech’s Senior Floating Rate Notes due 2013 (the “Old FR Notes”, CUSIP Number 034918AF9, and together with the FR Notes, the “Notes”). The redemption price for the Notes is equal to 100% of principal amount of the Notes, together with accrued and unpaid interest on the principal amount of the Notes to, but excluding, the redemption date, which is October 17, 2012. As of the date hereof, there are approximately $100 million in aggregate principal amount of FR Notes outstanding and $22,000 in aggregate principal amount of Old FR Notes outstanding.

“Our ability to proactively reduce our outstanding debt is the direct result of the strong business performance we have achieved during the first half of 2012,” said Thomas Bailey, President and CEO of Angiotech. “We feel this redemption transaction is a highly prudent use of our current excess cash resources, and will ultimately allow us the additional operational flexibility we will need to compete aggressively in our target markets.”
