The current quarter end total reflects a decrease of US$4,814,000 from the 30 September 2011 quarter end balance of US$69,201,000, primarily as a result of expenditures related to normal operating activities and capital equipment purchases of US$272,000.

REVA Medical, Inc. – ASX Announcement

About REVA

REVA is a development stage medical device company incorporated in Delaware, USA, that is focused on the development and eventual commercialisation of its proprietary bioresorbable stent products. REVA’s lead product, theReZolve™scaffold, combines REVA’s proprietary stent design with a proprietary polymer that is metabolised and cleared from the body. TheReZolvescaffold is designed to offer full x-ray visibility, clinically relevant sizing, and a controlled and safe resorption rate. In addition, by early encapsulation in the artery tissue coupled with the loss of scaffold structure over time, theReZolvescaffold may reduce the incidence of late forming blood clots, or thrombosis, a rare but serious problem associated with drug-eluting metal stents currently on the market. REVA will require clinical results and regulatory approval before it can begin selling theReZolvescaffold.
