Abstract
A measurement apparatus has a body that includes a reference surface that defines a reference line. The body further includes a first elongate window defining a first measurement line and a first measurement indicia positioned in association with the first elongate window. The first measurement line and the reference line define a first angle having a first magnitude. The first measurement indicia corresponds to the first magnitude.
Claims22
A measurement apparatus comprising:
- (a) a body, wherein:
- said body includes a reference surface that defines a reference line,
- said body further defines a plane, and said reference line lies within said plane,
- said body further defines (i) a left lateral side surface located on a first side of said plane, and (ii) a right lateral side surface located on a second side of said plane opposite to said first side of said plane,
- said left lateral side surface defines a first left lateral window opening,
- said right lateral side surface defines a first right lateral window opening,
- said body further includes a first elongate window that has its length extending in a first direction,
- said first elongate window defines a first measurement line extending in said first direction,
- said first elongate window extends from said first left lateral window opening to said first right lateral window opening,
- said body further includes a first measurement indicia positioned on said left lateral side surface in association with said first elongate window,
- said first measurement line and said reference line define a first angle having a first magnitude, and
- said first measurement indicia corresponds to said first magnitude;
- and
- (b) a guide wire catch projecting from said body, wherein (i) said guide wire catch includes a first catch portion and a second catch portion, (ii) said first catch portion is positioned on said first side of said plane, (iii) said second catch portion is positioned on said second side of said plane, (iv) said first catch portion is configured to define a first hook, and (v) said second catch portion is configured to define a second hook;
- and
- (c) a guide wire, wherein (i) said first hook defines a first contact surface, (ii) said second hook defines a second contact surface, (iii) said first hook is configured to receive said guide wire therethrough when said guide wire is positioned in contact with said first contact surface, and (iv) said second hook is configured to receive said guide wire therethrough when said guide wire is positioned in contact with said second contact surface.
