Optical fiber pressure sensor

An apparatus comprising:

• an elongated assembly, at least a portion of which is sized, shaped, or otherwise configured to be inserted into a human body to measure a pressure at an internal location within the body, wherein the elongated assembly includes:
• a guidewire assembly including:
• a distal tip;
• a discontinuous core wire that includes a first portion and a second portion, wherein the first portion includes a hollow core wire and the second portion is coupled to the distal tip;
• a tubular member extending through the hollow core wire and out a distal end of the hollow core wire;
• and
• a flexible distal member attached to the distal tip and to a distal end of the hollow core wire;
• an optical fiber pressure sensor coupled to an optical fiber;
• wherein the optical fiber extends through the tubular member, the optical fiber pressure sensor positioned between the first portion and the second portion;
• a sensor housing disposed about the pressure sensor;
• and
• a detachable optical connector configured to receive a proximal end of the guidewire assembly, wherein an end region of the optical connector defines a tapered region to guide the proximal end of the guidewire assembly into the optical connector.
