Abstract
Devices for removing clot material from a blood vessel lumen and associated systems and methods are disclosed herein. A clot retrieving device may include, for example, an elongated member, a cover having proximal, intermediate, and distal portions. The cover may be slideably coupled to the distal region of the elongated member at a connector. The cover may have an inner layer and an outer layer. The inner layer may have (a) a first cross-sectional dimension at the proximal portion of the cover, (b) a distally increasing cross-sectional dimension along the intermediate portion of the cover, and (c) a second cross-sectional dimension at the distal portion of the cover, wherein the second cross-sectional dimension is greater than the first cross-sectional dimension. The outer layer may have a cross-sectional dimension that is generally constant along the distal portion and the intermediate portion of the cover.
