1. A catheter comprising:
an elongate shaft including a proximal portion and a distal portion, the elongate shaft having a shaft wall, the shaft wall having a shaft wall outer surface and a shaft wall inner surface, the shaft wall inner surface defining a guidewire lumen, further wherein the shaft wall defines a pressure sensor wire lumen,
a communication wire extending proximally through the pressure sensor wire lumen;
a pressure sensor coupled to the shaft wall outer surface at the distal end of the elongate shaft, wherein the pressure sensor is spaced apart from a distal end of the communication wire forming a gap along the shaft wall outer surface;
electrical couplings provided in the shaft wall along the length of the gap and configured to electrically couple the pressure sensor with the communication wire,
wherein the communication wire is electrically coupled with the electrical couplings at an outer surface of the shaft wall and the pressure sensor and the communication wire are configured to move independently from one another in response to bending forces of the shaft wall resulting from when the elongate shaft is tracked to a treatment site within a vasculature.
