Abstract
An angioplasty pressure transducer includes a cylindrical member defining an inner cavity. The first end of the cylindrical member is provided with a fluid port allowing the passage of fluid into and out of the cylindrical member due to pressure changes in the physiological fluid being monitored. The angioplasty pressure transducer also includes a cylindrical elastomeric sleeve surrounding the cylindrical member. A cylindrical, transparent housing member is positioned about the cylindrical member such that a substantial portion of the outer surface of the cylindrical member, as well as the elastomeric sleeve, are enclosed and encased within the housing member. The cylindrical wall includes a plurality of small apertures spaced cylindrically about the circumference of cylindrical wall at a position substantially located at the longitudinal center of the cylindrical member, the apertures permitting pressurized fluid to pass between the inner cavity and the outer surface of the cylindrical member.
