Abstract
A guidewire including a thin elongated structure and an outer shell around at least a portion of the thin elongated structure. The outer shell includes a first portion and a second portion. The first portion and the second portion of the outer shell are each coupled to the thin elongated structure. The first portion is spaced from the second portion by a gap. The guidewire is configured to move between a flexible state and a rigid state. The gap has a first distance when the guidewire is in the flexible state and the gap has a second distance greater than the first distance when the guidewire is in the rigid state.

A guidewire comprising:
- a thin elongated structure;
- and
- an outer shell around at least a portion of the thin elongated structure, the outer shell comprising a first portion and a second portion, the first portion and the second portion each being coupled to the thin elongated structure,
- wherein the first portion is spaced from the second portion by a gap,
- wherein the guidewire is configured to move between a flexible state and a rigid state,
- wherein the gap has a non-zero first distance when the guidewire is in the flexible state, and
- wherein the gap has a second distance greater than the first distance when the guidewire is in the rigid state.
A guidewire comprising:
- a thin elongated structure;
- an outer shell around at least a portion of the thin elongated structure, the outer shell comprising a first portion and a second portion, the first portion and the second portion each being coupled to the thin elongated structure;
- and
- an outer stop coupled to the thin elongated structure,
- wherein the first portion is spaced from the second portion by a gap,
- wherein the guidewire is configured to move between a flexible state and a rigid state,
- wherein the gap has a first distance when the guidewire is in the flexible state,
- wherein the gap has a second distance greater than the first distance when the guidewire is in the rigid state, and
- wherein the outer stop is configured to maintain the first distance of the gap between the first portion and the second portion of the outer shell and prevent the first portion from contacting the second portion of the outer shell when the guidewire is in the flexible state.
