9. An electromagnetic sensing element with a center lumen, comprising:
a hollow tube comprising a proximal end, and distal end, and an inner lumen;
a coil wound around the hollow tube, disposed outside the inner lumen, and providing a mapping signal; and
a wire connected to the coil and transmitting the mapping signal to a processor,
wherein the center lumen has an inner diameter configured to pass a neurovascular device,
wherein the electromagnetic sensing element is configured to map the vascular system,
wherein the electromagnetic sensing element is configured for use with a force sensing element, the force sensing element comprising:
an electromagnetic transceiver configured for at least one of emitting or receiving a signal, the electromagnetic transceiver being fixed to a proximal end of the force sensing element;
an electromagnetic sensor configured for receiving the signal, the electromagnetic transceiver being disposed at the distal end of the force sensing element, slidable along the force sensing element, and configured for generating a position signal; and
a spring disposed between the electromagnetic transceiver and the electromagnetic sensor, the spring providing resistance to a proximal movement of the electromagnetic sensor,
wherein when the electromagnetic sensor is in a first position, the signal received by the electromagnetic sensor comprises a first frequency and a first power;
wherein when the electromagnetic sensor is in a second position, the signal received by the electromagnetic sensor comprises a second frequency and a second power;
wherein the position signal is generated based on at least one of the first frequency, the second frequency, the first power, and the second power, and
wherein the force sensing element is configured to detect a clot in a vascular system.
