Patent ID: 8277386

Claim:
A guide wire assembly, comprising: a flexible elongate tubular member having a proximal end and a distal end, a lumen extending therebetween defining an indoluminal surface, wherein the flexible elongate tubular member further comprises a plurality of coaxial polyimide layers and at least one of the plurality of coaxial polyimide layers defines the lumen of the flexible elongate tubular member, and wherein at least one longitudinal recess is defined within the indoluminal surface and extends longitudinally along a length of the tubular member, wherein the flexible elongate tubular member has an outer diameter of 0.014″; a core wire coaxially positioned in at least a portion of the lumen of the flexible elongate tubular member, wherein an outer diameter of the core wire is substantially the same size as a diameter of the lumen of the flexible elongate tubular member; a combination sensor housing coupled to the distal end of the flexible elongate tubular member, having a distal end and a proximal end, and a lumen extending therebetween; a flow sensor secured to the combination sensor housing; a pressure sensor disposed within the lumen of the combination sensor housing towards the distal end of the housing, wherein the pressure sensor and the flow sensor are located in close proximity to each other; a plurality of electrical connectors extending longitudinally from the pressure sensor to substantially the proximal end of the flexible elongate member; and a plurality of electrical connectors extending longitudinally from the flow sensor to substantially the proximal end of the flexible elongate member; wherein the pluralities of electrical connectors for the pressure sensor and the flow sensor are embedded between the polyimide layers of the flexible elongate tubular member and positioned within the at least one longitudinal recess.
