DEVICE, SYSTEM, AND METHOD FOR ASSESSING INTRAVASCULAR PRESSURE

摘要

What is described is an apparatus for intravascular pressure measurement, comprising an elongate body and a first pressure sensor. The elongate body includes a proximal portion and a distal portion, the body defines a distal guidewire lumen extending adjacent a sensor assembly along a distal portion of the system. The first pressure sensor is disposed within the wall of the distal portion of the body. An exterior surface of the sensor and the outer surface of the body are substantially aligned.

1. A sensing catheter for vessel pressure measurement, comprising:
an elongate catheter body including a proximal portion, an intermediate portion having a first perimeter and a distal portion having a second perimeter greater than the first perimeter, the distal portion defining a lumen extending from a proximal guidewire opening to a distal guidewire opening, the lumen sized and shaped to allow the passage of a guidewire therethrough, the body including an annular wall extending from the lumen to an outer surface of the distal portion; and a pressure sensor disposed within the annular wall of the body such that an exterior surface of the pressure sensor and the outer surface of the distal portion are substantially aligned to form a smooth outer surface for the distal portion adjacent the pressure sensor.
