Micrus Endovascular To Market Stretch-Resistant Microcoils in Japan

Micrus Endovascular Corporation (San Jose, CA, USA) has announced receipt of Shonin (direct registration) approval to market its full line of stretch-resistant microcoils for the endovascular treatment of cerebral aneurysms in Japan.

The Micrus MicroCoil System employs a frame and fill technique, whereby the aneurysm is first framed by deploying a spherically shaped microcoil that assumes an anatomically compliant frame within the aneurysm's fragile perimeter. A MicroSphere spherical coil is used to frame the aneurysm, and is placed and deployed within the aneurysm by means of a low temperature resistive heating (RH) delivery system. In aneurysms with greater than 4 mm diameter, a second spherical coil may be deployed to strengthen the frame. Subsequent HeliPaq helical coils are then used to fill the aneurysm until it is completely occluded from the cerebral circulation. Each microcoil detachment is accomplished with the push of a button. A selection of sizes is available to enable treatment of a range of aneurysm sizes.

Sales of Micrus stretch-resistant microcoils will be managed by Goodman Co. (Nagoya, Japan), Micrus Endovascular's exclusive distributor in the Japanese market, and will also include the Cashmere, Presidio, HeliPaq, and UltiPaq stretch-resistant embolic coils.

"We are very pleased to expand our product offering in Japan where we have already developed a significant presence. Our Micrus bare platinum microcoils are currently used in approximately half of all embolic procedures and, with the approval of our stretch-resistant microcoils, we now have the opportunity to build upon this foundation,” said John Kilcoyne, Micrus Endovascular Chairman and CEO. "Additionally, we continue to work with regulatory officials in Japan to gain approval for our Cerecyte bioactive microcoils.
