Abstract
A pressure-measuring guidewire system includes a hollow guidewire () in sealed interconnection with a contained volume () of a connector (). The contained volume is bordered on at least one side by a septum (). A pressure sensor unit () includes a transducer () associated with a hollow needle () which can be inserted to penetrate the septum (), thereby connecting the transducer with a column of fluid within an inner lumen of the guidewire (). Priming of the guidewire is performed prior to use, typically by use of a syringe, prior to connection of the sensor unit, thereby protecting the transducer from damage from the priming pressure. Also disclosed is a guidewire tip configuration which provides effective fluid connection for pressure measurement while maintaining the properties of a conventional guidewire.
