1. A medical assembly, the assembly comprising:
a catheter, the catheter comprising an elongate flexible shaft having a proximal end portion and a distal end portion, the proximal end portion comprising a port that is fixed in relation to a catheter handle, the distal end portion comprising a distal exit, wherein a working channel extends between the port and the distal exit, and a first localization element is attached to the catheter handle;
a medical instrument comprising a proximal end and a distal end and housed within the working channel, the proximal end of the medical instrument comprising a medical instrument handle, and a second localization element attached to the medical instrument handle, the distal end of the medical instrument comprising a needle, the needle having a tip; and
a navigation system in communication with a display, the navigation system configured to detect positions of the first localization element and the second localization element,
wherein the needle has a first position wherein the needle is positioned entirely within the working channel, in the first position the needle tip is in an unextended position,
the needle has a second position wherein the needle tip is extended through the distal exit to a position beyond the distal exit, in the second position the needle tip is in an extended position,
when the needle tip is in the unextended position the first localization element and the second localization element are in a zeroed out position,
when the needle tip is in the extended position, the first localization element and the second localization element are in an extension position such that a distance between the first localization element and the second localization element is less than the distance in the zeroed out position, and a difference in the distance between the zeroed out position and the extension position is determined by the navigation system as a needle stroke value and is displayed on the display.
