Abstract
A tissue tunneling device having a gripping mechanism for holding onto the body of the catheter. In one variation, the tissue tunneling device includes an elongate tunneler with a collet attached to the proximal end of the tunneler, and an oversleeve for providing compression to the collet to secure a distal or proximal portion of the catheter within the proximal end of the tunneling device. Internal ribs or surface profiles may be provided on an inner surface of the collet to prevent the catheter from moving when the collet is compressed onto the body of the catheter. The oversleeve may be configured such that over-sliding in the proximal direction is prevented. The collet may further be configured to receive the tips of a split-tip dialysis catheter.
