Abstract

A retrieval device can include inwardly facing protruding features that facilitate engagement and capture of a thrombus or other mass from a body lumen of a patient. The protruding features can deploy from a frame of the retrieval device to extend radially inwardly toward an opposing side of the frame. When deployed into a thrombus, the protruding features engage and urge the thrombus as the retrieval device moves to facilitate capture.
