Intravascular devices, systems, and methods are disclosed. In some embodiments, the intravascular devices include at least one pressure sensing component positioned within a distal portion of the device. In some instances, a plurality of conductors are electrically coupled to the pressure sensing component and a potting material covers the electrical connections between the plurality of conductors and the pressure sensing component. In some instances, the potting material has a durometer hardness between about 20 Shore A and about 50 Shore A, a moisture absorption rate of about 0% per twenty-four hours, a linear shrinkage of 0%, a coefficient of thermal expansion (m/m/-° C.) of between about 1.0×10-5 and about 5.0×10-4, and a volume resistivity (Omega-cm) between about 6.0×1013 and about 1.0×1014. Methods of making and/or assembling such intravascular devices/systems are also provided. |
