Santa Rosa, CA, November 18, 2013 – TriVascular, Inc. today announced the close of a 
$40 million Series E Preferred Stock equity financing. Existing investors New Enterprise 
Associates, Delphi Ventures, MPM Capital, Kearny Venture Partners, Kaiser Permanente 
Ventures and the Redmile Group were joined by new investors Deerfield Management, Rock 
Springs Capital and Permal Asset Management in the transaction. Proceeds from the 
financing will be used to expand commercial efforts worldwide and to fuel product pipeline 
and clinical research activities. 
“We are fortunate to have such strong financial support,” said Christopher G. Chavez, 
Chairman and CEO of TriVascular. “We welcome our new investors to the TriVascular family 
and are very grateful for the commitment of our existing investment syndicate. Our goal is to 
ensure that physicians and their patients gain access to minimally invasive endovascular 
aneurysm repair, which is enabled by the Ovation™ and Ovation Prime™ platforms. This 
financing further strengthens our ability to continue to invest in innovation and offer clinically 
compelling endovascular solutions.” 
In the U.S., the prevalence of abdominal aortic aneurysms is estimated at 2 million people. 
Many of these potential patients do not have access to minimally invasive, on-label 
endovascular aortic repair (EVAR) given the limitations of conventional wire-and-fabric 
technology. With an ultra low-profile (14F OD) delivery system and an innovative sealing 
technology, the Ovation and Ovation Prime platforms are designed to expand the on-label 
patient population suitable for EVAR. In October 2012, the U.S. FDA granted PMA approval 
for the Ovation system. The Ovation system received CE Mark clearance in August 2010. 
In August 2013, the one-year results from the Ovation pivotal study were published online 
by the Journal of Vascular Surgery. In October 2013, Manish Mehta, MD, MPH, Director of 
Endovascular Services for the Vascular Group in Albany, New York, presented two-year data 
on the Ovation pivotal study at the annual Vascular InterVentional Advances (VIVA) meeting 
in Las Vegas. The study demonstrated 100% freedom from Type I and III endoleaks, 
migration, rupture or conversion to open surgical repair at both the one-year and two-year 
marks. In addition, the pivotal trial cohort showed no aortic neck growth at either one or two 
years. 43% of the patients in the trial were treated via a percutaneous (PEVAR) vessel 
access method. Thirty-nine percent (39%) of the patients treated in the Ovation pivotal 
study would have been excluded from treatment in previous EVAR trials. The Ovation 
platform is approved for sale in over 30 countries. Approximately 2700 patients have been 
treated with the Ovation and Ovation Prime systems to date.
