Abstract

A clot retrieval device may include an elongate member and an expandable clot engaging element configured to extend across the clot in its expanded state. The expandable clot engaging element may include a first monolithic structure and a second monolithic structure. The first monolithic structure may encircle the second monolithic structure over at least a portion of its length. The second monolithic structure may include a proximal section, an intermediate section, and a distal section. The distal section may include an expansion.

Claims

1. A clot retrieval device comprising:

—

an elongate member,

and an expandable clot engaging element configured to extend across the clot in its expanded state,

the expandable clot engaging element comprising a first monolithic structure and a second monolithic structure, the first monolithic structure encircling the second monolithic structure over at least a portion of its length,

the second monolithic structure comprising a proximal section, an intermediate section and a distal section, the distal section comprising an expansion.
