主权项

1. A guidewire comprising:
a guidewire body having a distal end; a plurality of elements having a proximal section extending along a distal portion of the guidewire body, and a distal section in which the plurality of elements diverge radially outward from the distal end of the guidewire body to form a compliant structure having an expanded profile that is greater than a radial dimension of the distal end of the guidewire body and being resiliently deformable to a reduced profile, where in the expanded profile the compliant structure provides a radial force in an outward circumferential direction from an axis of the guidewire body.
