Assembly for introducing multiple catheters

Abstract

Abstract A method and assembly (20) for inserting a plurality of sensors into a biological fluid vessel for diagnosing the condition of the vessel or fluid. A pressure sensor (12) is described which is particularly adapted for use with a steerable guidewire (10) for selective positioning in the vessel. A guidewire (10) is inserted through the guiding catheter (32) and subselectively positioned in a region of interest in the coronary arterial tree. Multiple pressure sensors (12) are then threaded down the guidewire and positioned in the region of interest. In one version of the assembly, an angioplasty catheter is fitted to the guidewire and a pressure sensor device having a small flexible catheter body is fitted to the guidewire such that inserting the angioplasty catheter into a blood vessel also pushes the pressure sensor device into the vessel.
