摘要：
Apparatus (20) for performing a medical procedure within a patient's body, the apparatus comprises: a first magnetic field generator (32)； for its disposition outside the patient's body, to generate a first magnetic field inside the body； a probe (28), comprising: an insertion tube (54) having a distal end (30) for insertion into a cavity of a patient's body； a second magnetic field generator (64), within the distal end (30) for insertion of the tube (54) that generates a second magnetic field； a distal tip (52) that is flexibly coupled with the distal end (30) of the insertion tube (54)； and a sensor (62), which is disposed within the distal tip (52) and is configured to generate the first and second signals in response to the first and second magnetic fields, respectively； and a processor (36), which is coupled to receive and process the first signal to determine the coordinates of the distal tip (52) within the body and to receive and process the second signal to detect changes in a position of the distal tip ( 52) in relation to the distal end (30) of the insertion tube (54), comprising the axial displacement of the distal tip (52) and the deviation of the distal tip (52) in relation to the distal end (30) of the insertion (54). wherein the distal tip (52) is rigid, and wherein the probe (28) comprises a flexible member (58), which couples the distal tip (52) with the distal end (30) of the insertion tube (54) and It is configured to deform in response to the pressure exerted on the distal tip (52) when the distal tip (52) interacts with tissue within the body, and where changes in the position of the distal tip (52), are indicative of deformation of the flexible member (58)； wherein the processor (36) is configured to generate, in response to deformation, an output that is indicative of the pressure exerted on the distal tip (52).Aparato (20) para realizar un procedimiento médico dentro de un cuerpo de un paciente, el aparato comprende: un primer generador de c
