摘要：
A catheter system can include a first catheter having an elongated body that defines a lumen, and a second catheter slidably disposed within the lumen of the first catheter. The second catheter can include an acoustic device. The acoustic device can create a sound for verifying the location of the second catheter within a body lumen. The distal end portion of the second catheter can include a pre-formed bend that extends at a non-zero angle relative to a longitudinal axis of the first catheter. In some embodiments, the second catheter can be used to aspirate a substance from a body lumen.
