Abstract
A catheter may include an elongated tube enclosing at least one catheter lumen, and a centering device coupled to a distal end of the elongated tube, wherein the centering device includes a plurality of legs. Each leg of the plurality of legs may include a first end fixed to an outer surface of the elongated tube. Each leg of the plurality of legs may include an outward bias such that a central portion of each leg of the plurality of legs is spaced radially outward from the elongated tube when the centering device is in an expanded state.
Claims19
A catheter, comprising:
- an elongated tube enclosing at least one catheter lumen and having a distal terminus;
- and
- a centering device coupled to a distal end of the elongated tube, wherein the centering device includes a plurality of legs,
- wherein each leg of the plurality of legs includes a first end fixed to an outer surface of the elongated tube,
- wherein each leg of the plurality of legs includes an outward bias such that a central portion of each leg of the plurality of legs is spaced radially outward from the elongated tube when the centering device is in an expanded state, and
- wherein at least one leg of the plurality of legs extends distally beyond the distal terminus, and
- wherein the elongated tube includes a first opening configured to provide access to a first catheter lumen, wherein the first opening is at least partially surrounded by the legs of the centering device such that the legs are configured to prevent engagement between the first opening and a target body surface.
4 more elements
A catheter, comprising:
- an elongated tube enclosing at least one catheter lumen;
- a first opening located at a distal end of the elongated tube, the first opening being configured to provide access to a first lumen, the first lumen extending through the elongated tube;
- a second opening located at the distal end of the elongated tube, the second opening being configured to provide access to a second lumen, the second lumen extending through the elongated tube and being fluidly isolated relative to the first lumen within the elongated tube;
- and
- a centering device coupled to the distal end of the elongated tube, wherein the centering device is moveable between a delivery state and an expanded state, and wherein the centering device includes a bias towards the expanded state, and
- wherein the centering device includes a plurality of legs, wherein each leg of the plurality of legs includes a distal end that is spaced radially outward from the elongated tube when the centering device is in the expanded state, and wherein each end lacks a direct connection to the elongated tube when the centering device is in the delivery state.
