Abstract

An introducer assembly for introducing a catheter into a patient, includes a sheath having a distal end and a proximal end with a hollow lumen extending between the distal end and proximal end. The assembly also includes a coupler having a distal end operatively coupled to the proximal end of the sheath, the coupler having an internal passage in fluid communication with the hollow lumen. The assembly further includes a connector having a distal end operatively coupled to the coupler proximate the distal end of the coupler.

First claim

What is claimed is:

1. A robotic catheter system comprising:
a connector defining a pathway and including a first connection member, a second connection member and a breakaway portion, the breakaway portion being at a center portion of the connector, the center portion being at a separate location than the first connection member and the second connection member,
the connector including a region of alternating ridges and grooves proximate the first connection member;
a catheter extending through the connector, wherein the first connection member and the second connection member separable at the breakaway portion once a predetermined force is applied to the connector.

2. The robotic catheter system of claim 1 , wherein the breakaway portion is a friction connection.

3. The robotic catheter system of claim 1 , wherein the connector is coupled to a track with another portion of the robotic catheter system.

4. The robotic catheter system of claim 3 , wherein the connector is coupled to the track and an introducer.

5. The robotic catheter system of claim 4 , wherein the catheter extends through the introducer and the track.

6. The robotic catheter system of claim 4 , wherein the ridges and grooves form accordion folds that collapse or expand to permit the connector to have a greater or lesser distance between the track and the introducer.

7. The robotic catheter system of claim 1 , wherein the connector moves upon a predetermined compressive force applied to a distal end and a proximal end of the connector.

8. The robotic catheter system of claim 1 , wherein the connector buckles upon a predetermined compressive force applied to a distal end and a proximal end of the connector.

9. A robotic catheter system comprising:
a drive, operatively moving a catheter along a longitudinal axis;
a connector including,
a folding portion allowing a body to become longer and shorter along the longitudinal axis, the body defining a pathway,
a breakaway connection, the breakaway connection being at a center portion of the connector, the center portion being at a separate location than a first portion of the connector and a second portion of the connector, the breakaway connection permitting a first portion of the connector and the second portion of the connector to move at least one of toward or away from each other; and

the catheter extending through the pathway.

10. The robotic catheter system of claim 9 , wherein the body provides a pathway for the catheter to extend therethrough such that the body prevents buckling of the catheter.

11. The robotic catheter system of claim 9 , wherein the folding portion extends between a track and an introducer.

12. The robotic catheter system of claim 9 , wherein the connector includes a pivot.

13. The robotic catheter system of claim 12 , wherein the connector couples a track with another portion of the robotic catheter system.

14. The robotic catheter system of claim 9 , wherein the connector couples a track with another portion of the robotic catheter system.
