Abstract
The present document describes a pressure guidewire. It comprises a shaft tube having a proximal section configured to provide pushability to the pressure guidewire; a middle section extending distally relative to the proximal section, the middle section comprising a cut pattern configured to provide greater flexibility in the middle section than the proximal section; and a sensor housing section extending distally relative to the middle section. The pressure guidewire further comprises an inner hypotube comprising a proximal end portion and a distal end portion, the inner hypotube positioned entirely radially inward of the shaft tube and within at least the middle section, the proximal end portion and the distal end portion of the inner hypotube being joined to the shaft tube; and a tip pressure sensor positioned in the sensor housing section.
