Abstract
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.
Claims25
A catheter comprising:
- an elongated body having a proximal end portion and a distal end portion, the elongated body defining a lumen extending from the proximal end portion to the distal end portion;
- and
- an acoustic device that creates a sound at the distal end portion of the elongated body for verifying the location of the distal end portion within a body lumen.
A catheter system comprising:
- a first catheter including a first elongated body having a first proximal end portion, a first distal end portion, and a lumen extending from the first proximal end portion to the first distal end portion;
- and
- a second catheter slidably disposed within the first lumen of the first catheter, the second catheter including
- a second elongated body having a second proximal end portion, a second distal end portion, and a lumen extending from the second proximal end portion to the second distal end portion;
- and
- an acoustic device that creates a sound at the second distal end portion of the second catheter for verifying the location of the second distal end portion of the second catheter within a body lumen.
A catheter comprising:
- an elongated body having a proximal end portion and a distal end portion, wherein the elongated body defines a lumen extending from the proximal end portion to the distal end portion, and wherein the distal end portion of the elongated body includes a pre-formed bend that is configured to extend at a non-zero angle relative to a longitudinal axis of a body lumen when the catheter is disposed in the body lumen;
- and
- a directional indicator on the proximal end portion that indicates a radial direction at which the distal end portion extends from the longitudinal axis.
A method of using a catheter, comprising:
- inserting a distal end portion of a catheter into a body lumen;
- causing a sound to be created at the distal end portion of the catheter;
- and
- identifying a location of the sound to verify a position of the distal end portion of the catheter within the body lumen.
