Claim 0:
1. A medical device for measuring blood pressure, comprising:
an elongated shaft having a proximal region and a distal region and a lumen extending therethrough;
an optical pressure sensing block disposed within the lumen, the optical pressure sensing block including a central portion, a tapered distal portion having an outer surface that tapers distally from the central portion and a proximal portion that tapers proximally from the central portion, the optical pressure sensing block formed of glass;
a pressure sensing membrane disposed on a distal end of the optical pressure sensing block, the central portion and tapered distal portion in combination keeping the pressure sensing membrane from contacting a side wall of the lumen;
an optical fiber connector extending proximally from the proximal portion; and
an optical fiber extending through the lumen and coupled to the optical fiber connector.
