The InfinityTM sampling device is designed to collect substantial and high-quality samples from biliary strictures during ERCP procedures. It features stiff bristles that create defects in tissue and softer bristles that capture abraded material, along with spaces between the bristles to pack cells into the catheter. The device uses a nitinol drive wire for greater pushability and kink resistance. More information can be obtained by contacting US Endoscopy.
