Guidewire with adjustable tip

An adjustable guidewire comprising

• a distal portion comprising a coil segment, having a longitudinal axis and defining a lumen, at least a portion of the coil segment being compressible from a relaxed state, in which the coil segment aligns with the longitudinal axis, to a compressed state, in which the coil segment moves in a direction away from the longitudinal axis;
• a core member extending through the lumen of the distal portion and coupled to the distal portion at a point on the distal portion;
• and
• an elongate shaft operably associated with the distal portion such that movement of the elongate shaft translates the distal portion relative to the core member and compresses the coil segment from the relaxed state to the compressed state.

A method for adjusting a guidewire, the method comprising

• providing a guidewire comprising:
• an elongate member having a longitudinal axis, a defining a lumen, and including a distal portion, the distal portion comprising a coil segment and at least one portion of the coil segment being compressible from a relaxed state, in which the coil segment aligns with the longitudinal axis, to a compressed state, in which the coil segment moves in a direction away from the longitudinal axis;
• and
• a core member extending through the lumen of the elongate member and coupled to the elongate member at a point along the distal portion;
• introducing the guidewire into a body lumen;
• and
• adjusting the distal portion of the guidewire into one or more desired positions in the body lumen by moving the elongate member relative to the core member to compress the coil segment from the relaxed state to the compressed state.
