Concepts for catheter control and stabilization

A catheter guide device for facilitating precision positioning of a catheter inserted through a catheter sheath and into a patient, the catheter guide device comprising:

• a torque assembly configured to frictionally engage an exterior surface of the catheter to prevent rotation of the catheter relative to the torque assembly;
• and
• a hub rotatably secured to the torque assembly and configured to engage an upstream end of the catheter sheath and prevent rotation of the catheter sheath relative to the hub;
• wherein:
• the torque assembly defines a plurality of gear teeth on at least a portion of an exterior surface of the torque assembly;
• the hub comprises a detent mechanism configured to operably engage the plurality of gear teeth of the torque assembly and thereby impede free rotation of the torque assembly relative to the hub;
• and
• rotating the torque assembly relative to the hub rotates the catheter within the catheter sheath so as to facilitate precision positioning of the catheter.
