Biomedical pressure sensor for measuring the pressure in a fluid, wherein the biomedical pressure sensor comprises an optical fiber comprising at least one measurement section arranged at a distance from a distal end of the optical fiber, Wherein the biomedical pressure sensor further comprises a deforming member on the outer surface of the optical fiber at the location of the measurement section that is arranged for locally deforming the optical fiber under the influence of the applied pressure of the fluid to be measured and Wherein the measurement section is arranged for measuring said local deformation of the optical fiber.
