Catheter tip expandable in compression

Abstract

The systems and devices disclosed herein are for a clot retrieval catheter tip that can include a support frame that includes a longitudinal axis, a collapsed configuration, an expanded deployed configuration, and a plurality of interconnected struts. The plurality of interconnected struts can define an axial series of expansion cells and can be joined at opposing pairs of x-connectors spaced 180 degrees apart about the longitudinal axis. Each opposing pair of x-connectors can be rotated 90 degrees about the longitudinal axis with respect to an adjacent opposing pair of x-connectors. The support frame can further include a collapsed inner diameter in the collapsed delivery configuration and a larger expanded inner diameter in the expanded deployed configuration when the support frame is placed in compression.
