Multi-lumen catheter with detachable locking hub
First Claim
1. A detachable hub for a catheter comprising:
- a first portion having a first distal end, a first proximal end, and a longitudinal channel extending therethrough between the first distal end and the first proximal end;
wherein the first proximal end includes a pivoting locking member; and
a second portion having a second distal end, a second proximal end, wherein the second distal end includes a locking receiver, and wherein the longitudinal channel is sized to allow the first proximal end to be disposed over the second distal end such that the pivoting locking member is engageable with the locking receiver.

Abstract
A multi-lumen catheter assembly with a two-piece hub is disclosed. The catheter includes a distal portion having a plurality of catheter lumens, wherein each of the plurality of catheter lumens includes a distal tip and a proximal lumen portion. The distal portion further includes a distal hub portion slidably disposed over the proximal lumen portion, wherein the distal hub portion includes a pivoting locking member. The catheter assembly further includes a proximal portion having a plurality of catheter extensions, wherein each of the plurality of catheter extensions fluidly communicates with at least one of the plurality of catheter lumens. The proximal portion also includes a proximal hub portion having a locking receiver, wherein the pivoting locking member is releasably engaged with the locking receiver.
