1. A compressible rotor for a blood pump, the rotor comprising:
a hub; and
at least one conveying blade fastened to the hub,
wherein the at least one conveying blade comprises a plurality of struts,
wherein each strut of the plurality of struts has at least one joint,
wherein the at least one joint comprises a bearing that pivotably connects a first section of a strut to a second section of the strut such that a pivot lever portion of the first section is disposed on a first side of the bearing and a support lever portion of the first section is disposed on a second side of the bearing,
wherein the bearing permits:
(a) the first section of the strut to pivot relative to the second section of the strut in a first direction from an overelongated position of the strut to a kinked position of the strut, and
(b) the first section of the strut to pivot relative to the second section of the strut in a second direction from the kinked position of the strut to the overelongated position of the strut,
wherein, in the overelongated position, the first section and the second section partially overlap such that the support lever portion of the first section contacts the second section thereby preventing further pivoting of the first section relative to the second section in the second direction.
