MULTI-LUMEN CATHETER
A medical device, including an elongate catheter body defining a proximal segment, a distal segment, and a first lumen therethrough; a tube attached to the distal segment of the catheter body, the tube defining a proximal end, a distal end, and a second lumen therethrough; wherein the proximal end of the tube is attached to the catheter body at a first joint; wherein the distal end of the tube is attached to the catheter body at a second joint; and wherein a portion of the tube extending between the first and second joints is movable with respect to the catheter body.
1 . A medical device, comprising:
an elongate catheter body defining a proximal segment, a distal segment, and a first lumen therethrough;
a tube attached to the distal segment of the catheter body, the tube defining a proximal end, a distal end, and a second lumen therethrough;
wherein the proximal end of the tube is attached to the catheter body at a first joint;
wherein the distal end of the tube is attached to the catheter body at a second joint; and
wherein a portion of the tube extending between the first and second joints is movable with respect to the catheter body.
2 . The medical device of claim 1 , wherein the first joint includes a first cap concentrically mounted onto the proximal end of the tube, and wherein the first cap is attached to the catheter body.
3 . The medical device of claim 2 , wherein the second joint includes a second cap concentrically mounted onto the distal end of the tube, and wherein the second cap is attached to the catheter body.
4 . The medical device of claim 1 , wherein at least one of the first and second joints includes attachment of the tube to the catheter body with heat shrink tubing.
5 . The medical device of claim 1 , wherein the tube is at least partially constructed from a polymer, and wherein at least one of the first and second joints includes attachment of the tube to the catheter body by melt fusing a portion of the tube to a portion of the catheter body.
6 . The medical device of claim 1 , wherein at least one of the first and second joints includes attachment of the tube to the catheter body with an adhesive.
7 . The medical device of claim 1 , wherein the first lumen is not concentric with the second lumen.
8 . The medical device of claim 1 , further comprising a deflection element attached to the distal segment of the catheter body, the deflection element defining an arcuate surface positioned adjacent to the first lumen.
9 . The medical device of claim 8 , wherein the arcuate surface defines an arc between 45 degrees and 135 degrees.
10 . The medical device of claim 8 , wherein the deflection element defines a first opening substantially coaxial with the first lumen, a second opening that is substantially perpendicular to the first opening, and wherein the arcuate surface extends between the first and second openings.
11 . The medical device of claim 10 , wherein the deflection element defines a third opening substantially perpendicular to each of the first and second openings.
12 . The medical device of claim 8 , wherein the deflection element is radiopaque.
13 . The medical device of claim 8 , wherein the deflection element is movable with respect to the catheter body.
14 . The medical device of claim 8 , wherein the deflection element is movable along a longitudinal axis of the catheter body.
15 . A medical device, comprising:
an elongate catheter body defining a proximal segment, a distal segment, and a first lumen therethrough;
a tube attached to the distal segment of the catheter body, the tube defining a second lumen therethrough that is not concentric with the first lumen; and
a deflection element attached to the distal segment of the catheter body, the deflection element defining an arcuate surface positioned adjacent to a distal end of the first lumen, wherein the arcuate surface defines an arc between 45 degrees and approximately 135 degrees.
16 . The medical device of claim 15 , wherein the deflection element defines a first opening substantially coaxial with the first lumen, a second opening that is substantially perpendicular to the first opening, and wherein the arcuate surface extends between the first and second openings.
17 . The medical device of claim 15 , wherein the deflection element defines a third opening substantially perpendicular to each of the first and second openings.
18 . The medical device of claim 15 , wherein the deflection element is radiopaque.
19 . The medical device of claim 15 , wherein the deflection element is movable with respect to the catheter body.
20 . The medical device of claim 15 , wherein the deflection element is movable along a longitudinal axis of the catheter body.
21 . The medical device of claim 15 , wherein at least a portion of the tube is movable independently of the catheter body.
