Implantable catheter and method of using same
View Patent ↗A catheter for implantation into a patient having a catheter tube having a distal end, a means for trimming the distal end of the catheter tube after subcutaneous insertion of the tip of the catheter lumen into a desired position within the patient to form a trimmed end portion, and a means for selectively positioning each respective lumen of the trimmed end portion of the catheter tube into fluid communication with the respective first end of one attachment tube. The attachment tube is select fluid communication with a desired medical device.
1. A catheter for implantation into a patient, comprising:
a catheter tube having a distal end and an opposed tip, wherein at least a portion of the catheter tube comprises a radiopaque material, and wherein the catheter tube comprises at least one lumen;
a hub member having a proximal port and at least one distal port;
a means for trimming the distal end of the catheter tube after subcutaneous insertion of the tip of the catheter tube into a desired position within the patient to form a trimmed end portion, wherein the length of the catheter tube from the tip to the trimmed end portion is a desired length, wherein the means for trimming comprises a first cutting assembly mounted therein an interior portion of the hub member intermediate the proximal and distal ports of the hub;
at least one attachment tube mounted therein the hub member, each attachment tube having a first end, a second end and extending at least partially therebetween the proximal port and one distal port of the hub member, wherein the first cutting assembly is connected to the at least one attachment tube and is configured to longitudinally cut the lumen of the catheter tube as the catheter tube is drawn over the at least one attachment tube and past the first cutting assembly to form waste catheter tube; and
a means for selectively positioning each respective lumen of the trimmed end portion of the catheter tube into fluid communication with the respective first end of one attachment tube,
wherein a distal end portion of the lumen of the catheter tube is configured to fit axially about an exterior surface of the at least one attachment tube.
2. The catheter of claim 1 , wherein the first cutting assembly is a blade having at least one sharp edge.
3. The catheter of claim 2 , wherein the blade is positioned substantially co-planar to the longitudinal axis of the attachment tube.
4. The catheter of claim 1 , wherein the first cutting assembly comprises a pair of opposed first cutting assemblies that are mounted to respective portions of a pair of attachment tubes.
5. The catheter of claim 1 , further comprising a locking cap that is configured for slideable movement along an exterior surface of the catheter tube and is configured for selective connection to the proximal port of the hub member.
6. The catheter of claim 5 , further comprising a gasket sleeve configured to fix axially about the exterior surface of the catheter tube and the first end of the attachment tube such that, upon selective connection of the locking cap to the proximal port of the hub member, the catheter tube is securely attached to the first end of the attachment tube.
7. The catheter of claim 5 , further comprising a hemostatic taper sleeve having an end portion that is configured to be coupled to the locking cap, the hemostatic taper sleeve being configured for slidable movement along the exterior surface of the catheter tube.
8. The catheter of claim 7 , wherein the catheter tube comprises a dual lumen tube.
9. The catheter of claim 8 , wherein each lumen of the dual lumen tube has a generally D-shaped cross-section.
10. The catheter of claim 1 , wherein the first end of each attachment tube has a generally D-shaped cross-section and the second end of each attachment tube has a generally O-shaped cross-section.
11. The catheter of claim 1 , wherein the first end of each attachment tube has a generally O-shaped cross-section.
12. The catheter of claim 11 , wherein the catheter tube comprises a single lumen tube.
13. The catheter of claim 1 , wherein the hub member further comprises at least one conduit extending between the first cutting assembly and an exterior surface of the hub member that is configured for the waste catheter tube to be passed therethrough.
14. The catheter of claim 1 , wherein the means for trimming further comprises a waste cutting assembly mountable thereon the hub member for cutting off a portion of the waste catheter tube.
15. The catheter of claim 1 , further comprising at least one extension tube, each extension tube being connected to the second end of one attachment tube.
16. The catheter of claim 1 , wherein at least a portion of the tip of the catheter tube comprises the radiopaque material.
