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 lumen of the first catheter can also include a key joint component that corresponds to a key joint component on the second catheter. 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.
Claims33
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,
- wherein the elongated body includes a key joint component that corresponds with a key joint component of a lumen of a delivery catheter, and
- wherein the key joint component of the elongated body of the catheter is configured to be selectively coupled to the key joint component of the lumen of the delivery catheter such that a rotational orientation of the catheter is fixed relative to a rotation orientation of the delivery catheter.
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, the lumen having a first key joint component;
- and
- a second catheter slidably disposed within the lumen of the first catheter, the second catheter including a second elongated body having a second distal end portion and a second key joint component that corresponds with the first key joint component in the lumen of the first catheter,
- wherein the first key joint component and the second key joint component are configured to be coupled together such that a rotational orientation of the second catheter is fixed relative to a rotational orientation of the first catheter.
A catheter system comprising:
- a first catheter including a first elongated body having a first proximal end portion, a first distal end portion, and first and second lumens extending from the first proximal end portion to the first distal end portion;
- a second catheter slidably disposed within the first lumen of the first catheter, the second catheter including a second elongated body having a second distal end portion and a second proximal end portion, the second distal end portion of the second catheter including a pre-formed bend that extends at a non-zero angle relative to a longitudinal axis of the first catheter when the second distal end portion is extended from the first lumen of the first catheter;
- and
- a third catheter slidably disposed within the second lumen of the first catheter, the third catheter including a third elongated body having a third distal end portion and a third proximal end portion, the third distal end portion of the third catheter including a pre-formed bend that extends at a non-zero angle relative to the longitudinal axis of the first catheter when the third distal end portion is extended from the second lumen of the first catheter.
A method of using a catheter system, comprising:
- inserting an outer catheter into a first body lumen;
- coupling a key joint component on an inner catheter with a key joint component in a lumen of the outer catheter to fix a rotational orientation of the inner catheter relative to a rotational orientation of the outer catheter about the longitudinal axis of the body lumen;
- and
- advancing a distal end portion of the inner catheter away from a distal end portion of the outer catheter and into a second body lumen, the second body lumen branching from the first body lumen.
