GUIDEWIRE SIZING INSTRUMENTS, SYSTEMS, AND METHODS

A guidewire sizer that is integrated with a medical instrument the surgeon already uses in a surgical procedure involving a guidewire, or with another suitable item used in the surgical procedure is provided. The surgeon may, in some cases, use a single instrument for both measuring a guidewire diameter and performing at least one other task in a surgical procedure. The provided guidewire sizer may be a channel integrated with a body of a medical component, such as an instrument or other suitable item. The channel may be an indentation in the body's exterior surface or may be enclosed within the body. The channel includes at least two discrete portions that are each formed with a respective width that conforms to a dimension of a guidewire of a particular diameter, which enables measuring a guidewire diameter.
