Patent ID: 8900228

Claim:
A catheter, comprising: an elongated body; a distal electrode assembly mounted on the elongated body comprising an electrode having a shell configured with an inner chamber, the shell having a wall defining a proximal portion and a distal portion, the wall of the distal portion having at least one aperture; a micro-element extending through the inner chamber between the proximal portion and the distal portion, the micro-element having a distal end received in the at least one aperture, the distal end being at least coextensive with an outer surface of the wall; and a pressure-sensing assembly comprising: a coupling member, which couples the distal electrode assembly to the distal end of the elongate body; a position sensor configured to sense a position of the distal tip relative to the distal end of the elongated body, the position changing in response to deformation of the coupling member; a magnetic field generator within the distal end of the coupling member; wherein the position sensor is configured to generate a signal in response to a magnetic field, and wherein the signal is indicative of a position of the distal tip.
