The present invention relates to a guidewire comprising an elongated shape memory
alloy core (1) having a distal end and a proximal end, a portion (3) coupled to the
proximal end of the elongated shape memory alloy core (1), and a coating, wherein the
portion (3) comprising a LC circuit.
The present invention further provides a guide wire comprising a first elongated
shape memory alloy core (1) having a distal end and a proximal end, a second
elongated shape memory alloy core (2) having a distal end and a proximal end
substantially parallel to the shape memory alloy core (1), and a coating. Optionally, the
length and/or type of the shape memory alloy cores (1) and (2) are different.
In further embodiment, a portion (3) and/or (4) is coupled to the proximal end of the
elongated shape memory alloy core (1) and/or (2) according to the preceding
embodiment. Optionally, the portions (3) and/or (4) are composed of a different
material from the shape memory alloy core (1) and/or (2). Optionally, the portions (3)

and/or (4) comprise LC circuits. Optionally, the portions (3) and/or (4) of the present
invention comprise a metal, a plastic, LC circuit, a shape memory alloy or
combinations thereof.
In further embodiment, the guidewire according to any of the preceding
embodiments, comprising a non-conductive material coupled to the proximal end of
the guidewire. Optionally, the non-conductive material is coupled to the proximal end
of the portion (3) and/or (4).
In further embodiment, the guidewire according to any of the preceding
embodiment, wherein the LC circuit being designed to be powered by high-frequency
and/or magnetic fields generated from the MRI system and designed to transfer the
energy in form of heat to the elongated shape memory alloy core (1) and/or (2).
In further embodiment, the guidewire according to any of the preceding
embodiments, wherein the guidewire being designed to be detectable by x-rays, CT
scan, magnetic resonance imaging, or combinations thereto.
In further embodiment, the distal and/or the proximal end of the guidewire
according to any of the preceding embodiments is an open end being designed to
deliver a therapy device through the cores (1) and/or (2).
Additional embodiments provide systems comprising a guidewire according to any
of the preceding embodiments and a catheter. Optionally, the system further comprises
a therapy device and MRI system , CT Scan system, or x-ray system.
