Abstract
A catheter assembly includes a tubular first and second catheters in fluid communication with each other, wherein the second catheter includes a port fitting and can be elastically longitudinally strained to cinch the first and second catheters together.
Claims13
A catheter assembly comprising:
- a first catheter having a first end, a second end opposite the first end, an outer surface, an inner surface defining a first catheter lumen, and a side aperture;
- a second catheter having a first end, a second end opposite the first end, an outer surface, and an inner surface defining a second catheter lumen, the second catheter lumen being in fluid communication with the first catheter lumen via the side aperture in the first catheter;
- a first catheter port in fluid communication with the first catheter lumen and disposed at one of the first and second ends of the first catheter;
- a second catheter port in fluid communication with the second catheter lumen and disposed at one of the first and second ends of the second catheter;
- and
- a cinching mechanism including a protrusion extending from one of the first and second catheters and a recess formed in the other of the one of the first and second catheters, wherein the cinching mechanism utilizes an elastic longitudinal straining of the one of the first and second catheters to create a reactive force that retains the protrusion within the recess.

A catheter assembly comprising:
- a catheter having a first end, a second end opposite the first end, an outer surface, an inner surface defining a catheter lumen, and a side aperture;
- a port tube having a first end, a second end opposite the first end, an outer surface, and an inner surface defining a port tube lumen in fluid communication with the catheter lumen, and a side aperture;
- and
- a cinching mechanism including a protrusion extending from one of the catheter and the port tube and a recess formed in the other of the catheter and the port tube, wherein the cinching mechanism utilizes an elastic longitudinal straining of the port tube by tensioning the port tube to create a reactive force that retains the protrusion within the recess.
