These cystoscopes employ our patented EndoSheath technology, which are co-branded Stryker and Vision-Sciences. We also supply Stryker with flexible ureteroscopes under an agreement expiring in December 2015. Stryker has the exclusive rights to distribute products we manufacture, including cystoscopes, urology EndoSheath technology, and ureteroscopes, in North America, South America, Latin America, China, and Japan. Although Stryker was to receive the exclusive rights for the rest of the world in April 2012, we reached an agreement with Stryker to delay this launch indefinitely.  We also have a development and supply agreement with SpineView, Inc. (“SpineView”) under which we developed and supply a charge-coupled device (CCD) based video surgical endoscope for use with SpineView’s products. We received advances from Stryker for future orders and from SpineView for the initial stocking order of 50 SpineView surgical endoscope systems. All of the advances were fully utilized as of September 30, 2012.   falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for deferred revenues at the end of the reporting period, and description and amounts of significant changes that occurred during the reporting period.
