Abstract

Intravascular devices, systems, and methods are disclosed. In some embodiments, the intravascular devices include at least one electronic, optical, or electro-optical component positioned within a distal portion of the device and one or more connectors positioned at a distal portion of the device. In some instances, the connectors are flexible coils, such as a ribbon coil, formed of a conductive material. In some particular instances, the conductive coil is embedded within a polymer tubing. Further, in some embodiments the electronic, optical, or electro-optical component is positioned within a flexible element at the distal portion of the device. In some instances the flexible element is a coil. Methods of making and/or assembling such intravascular devices/systems are also provided.

Claims
