1. A catheter connector system, comprising:
- a catheter;
a connector sheath comprising a soft collet and a hard collet sheath, wherein the soft collet extends both proximally and distally beyond the hard collet sheath, and wherein the soft collet includes a lumen sized for slidable positioning over at least a proximal end of the catheter; and
a connector hub comprising a cannula sized for insertion into a lumen of the catheter and a distal interface with a cavity for receiving at least a portion of the soft collet, a proximal portion of the cavity configured to directly contact the soft collet and compress the soft collet against the proximal end of the catheter;
wherein one of the connector hub or the hard collet comprises at least one distally extending lock arm and the other comprises at least one external lock slot, wherein the at least one distally extending lock arm and the at least one external lock slot are configured to engage each other,wherein the connector hub is secured to the connector sheath by aligning the at least one distally extending lock arm and the at least one external lock slot and moving the connector sheath and the connector hub together in a straight motion with respect to the axis of the catheter until the at least one distally extending lock arm and the at least one external lock slot are locked together.

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.

14. A multi-lumen catheter connector, comprising:
-
a multi-lumen catheter; a unitary connector sheath comprising a soft collet and a hard collet sheath, wherein the hard collet sheath is fixedly retained to the soft collet, and wherein the proximal end and the distal end of the soft collet extend beyond the hard collet sheath; and a connector hub comprising a plurality of cannulas corresponding to the number of lumens in the multi-lumen catheter, wherein the plurality of cannulas are configured for insertion into a proximal end of the multi-lumen catheter, and wherein the connector hub comprises a cavity for receiving the soft collet, the cavity being configured to compress the proximal end of the soft collet against the proximal end of the multi-lumen catheter, the proximal end of the soft collet that extends beyond the proximal end of the collet sheath being configured to directly contact the connector hub; wherein one of the connector hub or the hard collet comprises at least one distally extending lock arm and the other comprises at least one external lock slot, wherein the at least one distally extending lock arm and the at least one external lock slot are configured to engage each other, wherein the connector hub is secured to the connector sheath by aligning the at least one distally extending lock arm and the at least one external lock slot and moving the connector sheath and the connector hub together in a straight motion with respect to the axis of the catheter until the at least one distally extending lock arm and the at least one external lock slot are locked together. - View Dependent Claims (15, 16, 17, 18, 19)
