Improved Stent for Biliary Blockage

A new self-expanding, crush-recoverable stent is designed to treat biliary obstructions, a life-threatening condition.

The stent's delivery system has two built-in mechanisms to help reduce unintentional stent movement during deployment. One enables doctors to advance the stent, gradually allowing for a more-controlled deployment. The second allows doctors to deploy the stent in one smooth, controlled motion. The stent is laser-cut from Nitinol, an alloy of nickel and titanium that provides shape-memory properties for easy, predictable placement. Called the Smart Control Stent, the device is the product of Cordis Endovascular (Warren, NJ, USA).

"Last year, we greatly improved the ability to visualize the stent during predeployment, initial stent release, and postdeployment by launching the Smart Transhepatic Biliary Stent with Micro Marker technology,” said Carol L. Zilm, president of Cordis Endovascular, a Johnson & Johnson company. "Now, we have the third generation of this product line, giving physicians the ability to single-handedly experience a more controlled delivery.”
