摘要:
An intravascular ultrasound “(IVUS”) device having an intrinsic or attachable needle guide is disclosed. In some embodiments, a sheath having a needle guide is used in connection with an IVUS device. The devices may be used in performing minimally invasive image-guided surgical procedures. The devices may be configured to maintain a needle placed through guide in the plane of the IVUS-array to improve visualization of the needle. In some embodiments, the device is used to facilitate the creation of a tract through the liver from the inferior vena cava to the portal vein using IVUS-guidance in a direct intrahepatic portocaval shunt procedure. The devices, systems, and methods can improve patient safety by decreasing the risk of off-target punctures, decrease procedure times, and allow procedures to be performed from a single access site.
