Abstract
Embodiments relate to multi-focal intravascular pressure catheters and related systems and methods. In an embodiment, a catheter comprises a plurality of pressure sensors spaced apart along at least a portion of the catheter. Each of the plurality of pressure sensors can comprise a pressure membrane arranged over an aperture in the catheter. In an embodiment, the pressure membrane can comprise carbon nanotubes, silver or gold nanoparticles, or another suitable material that can provide a signal in response to a mechanical change (e.g., deformation or flexing of the pressure membrane) to indicate a pressure or change in pressure. Signals from the plurality of pressure sensors can be communicated to an electrical interface which can calibrate or convert the signals into a visual indication of the pressure at any one of the plurality of pressure sensors as well as pressure gradients between various ones of the plurality of pressure sensors.
