摘要： A system and method for guiding a catheter or other medical device to a desired target destination within the vasculature of a patient via bioimpedance measurements is disclosed. The target destination in one embodiment includes placement of the catheter such that a distal tip thereof is disposed proximate the heart, e.g., the junction of the right atrium and superior vena cava. In one embodiment the method for guiding the catheter comprises introducing the catheter into a vessel of the patient, the catheter defining a lumen through which fluids can be infused into the vasculature of the patient. The catheter is advanced toward a target destination within the vasculature. A first impedance value based on intravascular detection of at least one electrical property related to a first tissue surface of the vessel is calculated to enable determination of the proximity of a distal end of the catheter to the target destination.

摘要： A sacrificial catheter assembly and method of use for placing a functional catheter within the body of a patient, such as into the patient's vasculature, is disclosed. In one embodiment, the sacrificial catheter assembly comprises a sacrificial catheter including an elongate body that defines a longitudinally extending lumen. A stylet is removably received within the lumen of the sacrificial catheter such that the catheter and stylet can be advanced together to a target destination within the body of the patient. The sacrificial catheter is configured so as to then be proximally slid over the stylet to remove the sacrificial catheter from the body while the stylet remains in place at the target destination. A functional catheter can then be distally slid over the stylet to place the functional catheter at the target destination. The stylet can then be removed from the body of the patient.
