  "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.",
  "claims": [
    "1. (canceled) 2. (canceled) 3. (canceled) 4. A robotic catheter system comprising: a connector defining a pathway and including a first connection member and a second connection member, the connector including a region of alternating ridges and grooves proximate the first connection member; a catheter extending through the connector. 5. The robotic catheter system of claim 4, wherein the connector includes a breakaway portion. 6. The robotic catheter system of claim 5, wherein the breakaway portion is a friction connection. 7. The robotic catheter system of claim 5, wherein the first connection member and second connection member separate once a predetermined force is applied to the connector. 8. The robotic catheter system of claim 6, wherein the first connection member and second connection member separate once a predetermined force is applied to the connector. 9. The robotic catheter system of claim 5, wherein the connector is coupled to a track with another portion of the robotic catheter system. 10. The robotic catheter system of claim 9, wherein the connector is coupled to the track and an introducer. 11. The robotic catheter system of claim 10 wherein the catheter extends through the introducer and the track. 12. The robotic catheter system of claim 10, 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. 13. The robotic catheter system of claim 4, wherein the connector moves upon a predetermined compressive force applied to a distal end and a proximal end of the connector. 14. The robotic catheter system of claim 4, wherein the connector buckles upon a predetermined compressive force applied to a distal end and a proximal end of the connector. 15. A robotic catheter system comprising: a drive, operatively moving a catheter along a longitudinal axis; a body including a folding portion allowing the body to become longer and shorter along the longitudinal axis, the body defining a pathway; and the catheter extending through the pathway. 16. The robotic catheter system of claim 15, wherein the body provides a pathway for the catheter to extend therethrough such that the body prevents buckling of the catheter. 17. The robotic catheter system of claim 15, wherein the folding portion defines an accordion region that collapses or expands to permit the pathway to have a greater or lesser distance. 18. The robotic catheter system of clam 15, wherein the folding portion extends between a track and an introducer. 19. The robotic catheter system of claim 15, wherein the folding portion includes a pivot. 20. The robotic catheter system of claim 19, wherein the folding portion is a connector coupling a track with another portion of the robotic catheter system. 21. The robotic catheter system of claim 15, wherein the folding portion is a connector coupling a track with another portion of the robotic catheter system. 22. A robotic system comprising: a drive, operatively moving a device along a longitudinal axis; a body including a folding portion allowing the body to become longer and shorter along the longitudinal axis, the body defining a pathway for the device. 23. The robotic system of claim 15, wherein the folding portion is a connector including a pivot portion."

  "description_excerpt": "The present invention relates generally to the field of catheter systems for performing diagnostic and/or intervention procedures. The present invention relates specifically to a guide catheter control in robotic catheter system with an introducer connector.\n\nVascular disease, and in particular cardiovascular disease, may be treated in a variety of ways. Surgery, such as cardiac bypass surgery, is one method for treating cardiovascular disease. However, under certain circumstances, vascular disease may be treated with a catheter based intervention procedure, such as angioplasty. Catheter based intervention procedures are generally considered less invasive than surgery.\n\nDuring one type of intervention procedure, a guide catheter is inserted into a patient's femoral artery through an introducer and positioned proximate the coronary ostium of a patient's heart. A guide wire is inserted into the guide catheter typically through a hemostasis valve and maneuvered through the patient's arterial system until the guide wire reaches the site of the lesion. A working catheter is then moved along the guide wire until the working catheter such as a balloon and stent are positioned proximate the lesion to open a blockage to allow for an increased flow of blood proximate the lesion. In addition to cardiovascular disease, other diseases may be treated with catheterization procedures.\n\nIn accordance with an embodiment, an introducer includes a coupler having a distal end configured to operatively couple a sheath and a connector extending from the proximal end of the coupler.",
