Apparatus and method for endovascular device guiding and positioning using physiological parameters

Abstract

An endovascular navigation system and method are disclosed. The endovascular navigation system includes an elongate flexible member configured to access the venous vasculature of a patient, a processor, and a display. The elongate flexible member includes an endovascular electrogram lead disposed at a distal end of the elongate flexible member and configured to sense an endovascular electrogram signal of the venous vasculature of the patient, and a first wireless interface configured to wirelessly transmit the endovascular electrogram signal to the processor. The processor includes a second wireless interface configured to wirelessly receive the endovascular electrogram signal from the elongate flexible member. The processor is configured to determine that the position of the distal end of the elongate flexible member is within a predetermined structure within the venous vasculature of the patient. The display is configured to display a visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient.

What is claimed is: 
     
         1 . An endovascular navigation system, comprising:
 an elongate flexible member configured to access the venous vasculature of a patient, the elongate flexible member comprising:
 an endovascular electrogram lead disposed at a distal end of the elongate flexible member and configured to sense an endovascular electrogram signal of the venous vasculature of the patient; and 
 a first wireless interface configured to wirelessly transmit the endovascular electrogram signal to a processor; 
   the processor comprising a second wireless interface configured to wirelessly receive the endovascular electrogram signal from the elongate flexible member, the processor being configured to determine, based at least in part on the endovascular electrogram signal, that the position of the distal end of the elongate flexible member is within a predetermined structure within the venous vasculature of the patient; and   a display configured to display, in response to the determination that the position of the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient, a visual indication that the distal end of the elongate flexible member is within the predetermined structure within the venous vasculature of the patient,   wherein the visual indication is different from the endovascular electrogram signal of the venous vasculature of the patient.
