The present invention relates to the field of medical monitoring, and in particular non-contact monitoring of one or more physiological parameters in a region of a patient during surgery. Systems, methods, and computer readable media are described for generating a pulsation field and/or a pulsation strength field of a region of interest (ROI) in a patient across a field of view of an image capture device, such as a video camera. The pulsation field and/or the pulsation strength field can be generated from changes in light intensities and/or colors of pixels in a video sequence captured by the image capture device. The pulsation field and/or the pulsation strength field can be combined with indocyanine green (ICG) information regarding ICG dye injected into the patient to identify sites where blood flow has decreased and/or ceased and that are at risk of hypoxia.

A catheter with three distinct compression resistance coils, including a body coil and two pull wire coils, is disclosed. The triple coil system can provide maximal resistance to compression of the catheter's proximal shaft, as well as maximization of the curve angle that the catheter tip can achieve. Additionally, the tri-coil catheter can allow for a lower initial compression load and a more flexible proximal shaft. A gap between the outer diameter of the pull wire and the inner diameter of the pull wire compression coil that is equal to about 10-30% of inner diameter of the pull wire compression coil can provide optimal catheter performance.
