The present disclosure provides a catheter grip device that secures to a catheter shaft and provides easier manipulation of the catheter shaft for the user. For example, the catheter shaft, such as for an Electrophysiology catheter, may insert into a patients blood vessel. From here, the user, such as the physician, may need to manipulate, re-position, rotate, or otherwise maneuver a distal end of the catheter shaft while inserted inside the patients blood vessel. In this regard, by the catheter grip being securely attached to the catheter shaft, the user is able to manipulate, rotate, etc. the catheter shaft by rotating and manipulating the catheter grip. The catheter grip reduces strain on the various muscles of the users hand, and also provides more accurate manipulation of the catheter shaft.
