Abstract:
1. A method for determining the severity of an intravascular occlusion, the method comprising: advancing a pressure-sensing medical device through a blood vessel; wherein the pressure-sensing medical device includes an outer tubular member, an inner tubular member, and a pressure sensor; wherein the inner tubular member has a first opening formed therein; wherein the outer tubular member has a distal opening formed therein adjacent to a distal end of the outer tubular member and a proximal opening formed therein at a position proximal of the distal opening; wherein advancing a pressure-sensing medical device through a blood vessel includes advancing the pressure-sensing medical device to a position where the distal opening is disposed distally of an intravascular occlusion and the proximal opening is disposed proximally of the intravascular occlusion; disposing the inner tubular member at a first position within the outer tubular member where the first opening is substantially aligned with the distal opening; measuring a first pressure within the blood vessel while the inner tubular member is disposed at the first position; disposing the inner tubular member at a second position within the outer tubular member where the first opening is substantially aligned with the proximal opening; and measuring a second pressure within the blood vessel while the inner tubular member is disposed at the second position.
