    • 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.
    • 公开了一种牺牲导管组件和用于将功能导管置于患者身体内的使用方法,例如进入患者的脉管系统。 在一个实施例中,牺牲导管组件包括牺牲导管,其包括限定纵向延伸腔的细长体。 探针可移除地容纳在牺牲导管的管腔内,使得导管和探针可以一起前进到患者体内的目的地。 牺牲导管被配置成随后在导管上向近侧滑动,以在探针保持在目的地的位置时从身体移除牺牲导管。 然后可以在功能导管远端滑过管心针,将功能导管置于目的地。 然后可以从患者的身体移除探针。
