Abstract

A powered catheter and/or powered catheter system is described. The catheter includes a catheter hub with one set of contact components that are configured to connect to a mating cable with a corresponding second set of contact components. The mating cable can be part of another device, such as a controller or power source.

First claim

What is claimed is:

1. A catheter hub, comprising:
a hub body;
a hub passage extending longitudinally between a proximal end and a distal end of the hub body; and
a catheter connector assembly integral with the hub body and exterior to the hub passage, the catheter connector assembly comprising a frictional engagement mechanism,
wherein the frictional engagement mechanism comprises a plurality of posts and a magnetic engagement mechanism between the plurality of posts.

2. The catheter hub of claim 1 , wherein, in an engaged configuration, each of the plurality of posts engage with a hole on an interface connector assembly.

3. The catheter hub of claim 2 , wherein the interface connector assembly is an electrical interface,
where in the engaged configuration, the electrical interface is in electrical connection with a plurality of wires, and
wherein the plurality of wires are electrically connected to an electrical path within a body of a catheter.

4. The catheter hub of claim 3 , wherein the catheter further comprises a lumen in fluid communication with the hub passage of the hub body.

5. A catheter system, comprising:
a catheter hub comprising a hub body, a hub passage extending longitudinally between a proximal end and a distal end of the hub body, and a catheter connector assembly adjacent to the hub passage, wherein the catheter connector assembly comprises a frictional engagement mechanism; and
an interface connector assembly; and,
wherein, in an engaged configuration, the interface connector assembly of the interface connector assembly frictionally engages with the frictional engagement mechanism of the catheter hub;
wherein, in the engaged configuration, the interface connector assembly is in electrical communication with a catheter; and,
wherein the catheter comprises a lumen in fluid communication with the hub passage of the catheter hub.

6. The catheter system of claim 5 , wherein the frictional engagement mechanism is comprised of a projection; wherein the interface connector assembly includes an indentation; and wherein, in the engaged configuration, the projection of the frictional engagement mechanism frictionally engages with the indentation of the interface connector assembly.

7. The catheter system of claim 5 , wherein the frictional engagement mechanism is comprised of an indentation; wherein the interface connector assembly includes a projection; and wherein, in the engaged configuration, the indentation of the frictional engagement mechanism frictionally engages with the projection of the interface connector assembly.

8. A catheter hub, comprising:
a hub body;
a hub passage extending longitudinally between a proximal end and a distal end of the hub body; and
a catheter connector means adjacent to the hub passage, the catheter connector means comprising a frictional engagement means for frictionally engaging with an interface connection means; and,
wherein the frictional engagement means comprises an elongated C-shaped channel.

9. The catheter hub of claim 8 , further comprising a magnetic engagement mechanism positioned within the elongated C-shaped channel.

10. The catheter hub of claim 8 , further comprising a magnetic engagement mechanism adjacent to the elongated channel.

11. The catheter hub of claim 8 , wherein, in an engaged configuration, a raised ridge of an interface connector assembly mates with the elongated channel.

12. A catheter hub, comprising:
a hub body;
a hub passage extending longitudinally between a proximal end and a distal end of the hub body; and
a catheter connector assembly integral with the hub body and exterior to the hub passage, the catheter connector assembly comprising a frictional engagement mechanism,
wherein the frictional engagement mechanism comprises a cylindrical, triangular, rectangular, or hexagonal projection.

13. The catheter hub of claim 12 , wherein, in an engaged configuration, the rectangular projection engages with a rectangular depressed region of an interface connector assembly.

14. The catheter hub of claim 12 , further comprising a magnetic engagement mechanism positioned on the rectangular projection.

15. The catheter hub of claim 12 , wherein the rectangular projection includes downwardly-angled sides.
