Adjustable length catheter
View Patent ↗An adjustable length catheter device, a kit and a method of providing the adjustable length catheter device to a patient are provided. The catheter device includes an elongate shaft having a proximal portion, a distal portion, a first lumen and a second lumen extending at least partially therethrough. The catheter device further includes a manifold operably connected to the shaft. The manifold is configured to longitudinally move along the shaft towards the distal portion for separating the proximal portion of the shaft into a first proximal shaft portion including the first lumen and a second proximal shaft portion including the second lumen.
1. An adjustable length catheter device for fluid flow therethrough, the catheter device comprising:
an elongate shaft having a proximal portion and a distal portion, and further having a first lumen and a second lumen extending at least partially therethrough; and
a manifold movably connected to the shaft, the manifold comprising a contacting portion including a separator device comprising a cutting element that contacts a portion of the shaft between the first and second lumens, a first manifold lumen and a second manifold lumen extending at least partially through the manifold, the manifold having a first position and a second position relative to the shaft, the second position being distal to the first position, the manifold is longitudinally movable along the shaft from the first position to the second position to separate the proximal portion of the shaft into a first proximal shaft portion including the first lumen and a second, separate proximal shaft portion including the second lumen as the manifold moves distally to the second position.
2. The catheter device of claim 1 , wherein the cutting element is recessed within the manifold.
3. The catheter device of claim 1 , further comprising a locking mechanism configured for selectively preventing movement of the manifold relative to the shaft.
4. The catheter device of claim 3 , wherein the manifold comprises the locking mechanism.
5. The catheter device of claim 1 , further comprising fittings connectable to the first proximal shaft portion and the second proximal shaft portion.
6. The catheter device of claim 5 , wherein each fitting comprises a cap, a sleeve and an adaptor.
7. The catheter device of claim 1 , wherein the shaft comprises a first shaft section and a second shaft section, wherein the first shaft section overlaps the second shaft section.
8. The catheter device of claim 1 , wherein the catheter device is a hemodialysis catheter and the first lumen comprises an infusion lumen and the second lumen comprises an aspiration lumen.
9. The catheter device of claim 1 , wherein at least a portion of the device includes an antimicrobial coating.
10. An adjustable length catheter device for fluid flow therethrough, the catheter device comprising:
an elongate shaft having a proximal portion and a distal portion, and further having a first lumen and a second lumen extending at least partially therethrough; and
a manifold movably connected to the shaft, the manifold comprising a contacting portion that contacts a portion of the shaft between the first and second lumens, a first manifold lumen and a second manifold lumen extending at least partially through the manifold, the manifold having a first position and a second position relative to the shaft, the second position being distal to the first position, the manifold is longitudinally movable along the shaft from the first position to the second position to separate the proximal portion of the shaft into a first proximal shaft portion including the first lumen and a second, separate proximal shaft portion including the second lumen as the manifold moves distally to the second position,
wherein the shaft comprises a central portion extending longitudinally along the shaft between the first lumen and the second lumen, the central portion being configured to facilitate separation of the shaft.
11. The catheter device of claim 10 , wherein the central portion comprises a frangible portion.
12. The catheter device of claim 10 , wherein the central portion comprises a central lumen.
