Abstract
An assembly comprising: a first tube defining a first surface; a second tube defining a second surface, wherein the second surface is configured to contact the first surface at an interface; a fixation mechanism comprising: a first split flange disposed around the first tube; a second split flange disposed around the second tube; and one or more springs coupled to the first split flange and the second split flange, wherein the one or more springs are configured to transfer a relative force between the first tube and the second tube and towards the interface, and wherein the second split flange is configured to be disposed between the interface and the one or more springs.

An assembly comprising:
- a first tube defining a first surface at a first end of the first tube;
- a second tube defining a second surface at a second end of the second tube, wherein the second surface of the second tube is configured to contact the first surface of the first tube at an interface, and wherein the first tube and the second tube define different coefficients of thermal expansion (CTE);
- a fixation mechanism configured to be disposed around the first tube and the second tube at the interface, the fixation mechanism comprising:
- a first split flange disposed around the first tube;
- a second split flange disposed around the second tube;
- and
- one or more springs coupled to the first split flange and the second split flange,
- wherein the first tube and the second tube define a longitudinal axis extending through the interface,
- wherein the one or more springs are configured to transfer a relative force between the first tube and the second tube and towards the interface, and
- wherein the second split flange is configured to be disposed longitudinally between the interface and the one or more springs.
A method comprising:
- placing a first surface at a first end of a first tube into contact with a second surface at a second end of a second tube at an interface,
- wherein the first tube and the second tube define different coefficients of thermal expansion (CTE), and
- wherein when the first surface contacts the second surface, the first tube and the second tube define a longitudinal axis extending through the interface;
- affixing a first split flange of a fixation mechanism around the first tube at or around the interface;
- affixing a second split flange of the fixation mechanism around the second tube at or around the interface;
- advancing one or more elongated bodies through the first split flange and the second split flange to connect the first split flange to the second split flange;
- and
- disposing one or more springs over the one or more elongated bodies, wherein the second split flange is longitudinally between the interface and the one or more springs, and wherein the one or more springs are configured to transfer a relative force between the first tube and the second tube and towards the interface.
A fixation mechanism comprising:
- a first split flange configured to be disposed around a first end of a first tube at or around an interface between the first tube and a second tube;
- a second split flange configured to be disposed around a second end of the second tube at or around the interface, wherein the second end of the second tube contacts the first end of the first tube at the interface;
- two or more elongated bodies extending through the first split flange and the second split flange parallel to a longitudinal axis of the fixation mechanism, wherein the two or more elongated bodies are configured to connect the first split flange to the second split flange, and
- two or more springs, each spring of the two or more springs being disposed around a respective elongated body of the two or more elongated bodies, wherein the two or more springs are configured to transfer a relative force between the first tube and the second tube and towards the interface,
- wherein the second split flange is configured to be disposed longitudinally between the first split flange and the two or more springs, and
- wherein the first tube and the second tube define different coefficients of thermal expansion (CTE).
