Tunneling system
View Patent ↗A tunneling system includes an elongate tunneling member defining a longitudinal axis along at least a portion of a longitudinal length thereof. The elongate tunneling member has a first end and a second end. The second end of the elongate tunneling member includes a coupling segment adapted for securely engaging a catheter.
1. A tunneling system comprising:
a catheter having a proximal end, a distal end, first and second longitudinal lumens separated by a septum, and at least one hole extending through the septum from the first longitudinal lumen to the second longitudinal lumen and providing passage between the first and second lumens, the at least one hole being spaced from the proximal end of the catheter; and
an elongate tunneling member defining a longitudinal axis along at least a portion of a longitudinal length thereof, the elongate tunneling member having a first end and a second end, the second end including a coupling segment integrally formed therewith, the coupling segment adapted for at least partial reception within at least one of the longitudinal lumens of the catheter, and wherein the coupling segment includes at least one protrusion adapted to be received within the at least one hole extending through the septum to secure the catheter to the tunneling member.
2. The tunneling system according to claim 1 , wherein the at least one protrusion includes a hook adapted to engage the hole extending through the septum.
3. The tunneling system according to claim 2 , wherein the hook defines an acute angle with respect to the longitudinal axis defined by the elongate tunneling member.
4. The tunneling system according to claim 2 , wherein the hook extends toward the proximal end of the catheter when the coupling segment is received within the at least one hole extending through the septum.
5. The tunneling system according to claim 1 , wherein the first and second longitudinal lumens are D-shaped lumens.
6. The tunneling system according to claim 1 , wherein the coupling segment is adapted for at least partial reception in either of the first and second longitudinal lumens.
