Abstract

A catheter connector system that allows trimming of the proximal end of a catheter (single or multiple lumen) prior to the placement of a connector hub. In one variation, the catheter connector system comprises a catheter, a connector sheath including a soft collet, and a connector hub including a cannula for engaging the catheter and a connector hub interface for receiving the connector sheath.

Claims

1. A method of establishing a bifurcating connection to a catheter comprising:

inserting a distal portion of a dual lumen catheter into a patient'"'"'s body;

cutting off a proximal section of the dual lumen catheter to form a proximal connection end on the dual lumen catheter;

inserting two distally extending cannulas on a bifurcation into the proximal connection end of the dual lumen catheter;

and advancing a connector sheath comprising a hard collet sheath radially surrounding at least a portion of a soft collet proximally over a shaft of the dual lumen catheter, which results in a distal portion of the bifurcation compressing a proximal portion of the connector sheath towards the catheter to secure the catheter to the two distally extending cannulas.

2. The method according to claim 1, further comprising the step of engaging a locking mechanism on the bifurcation with the connector sheath, and securing the connector sheath onto the bifurcation.

3. The method according to claim 2, wherein the step of engaging a locking mechanism further comprises inducing an audible sound to notify a user of successful attachment.

4. The method according to claim 3, wherein the audible sound is at least about 60 dB.

5. The method according to claim 2, wherein after completion of the engaging a locking mechanism step, a resulting connection between the connector sheath and the bifurcation has a minimum pull of force of about 3.37 lbs.
