Abstract
The present disclosure is directed to embodiments of devices for capturing obstructions within passageways. The devices disclosed herein may include a flexible tubular body forming multiple flexible members arranged in a helical pattern. These flexible members may be expandable to form one or more cages when the tubular body is expanded to an increased diameter state. The cages may be generally centered around the longitudinal axis of the tubular body between the two ends of the body. Also disclosed herein are methods for capturing obstructions within passageways, methods for obtaining tissue samples from body passages, and methods for making devices for capturing obstructions within passageways.
