FFR SENSOR HEAD DESIGN THAT MINIMIZES STRESS INDUCED PRESSURE OFFSETS |
摘要 |
A pressure sensing medical device may include a guidewire including a tubular member having a lumen, the tubular member being translatable between a generally straightened position and a deflected position, and a pressure sensor attached at a distal end of a fiber optic extending within the lumen, the pressure sensor being disposed within a distal portion of the tubular member. The pressure sensor may include a pressure-sensitive membrane disposed on a distal end thereof. The pressure sensor may include one or more contact members capable of providing a contact point between the contact member and an inner surface of the tubular member when in the deflected position, the contact point being axially spaced apart from the membrane along a longitudinal axis of the pressure sensor. |
