Catheter deployment device

A catheter device comprising:

• a housing;
• an inner key extending distally from the housing;
• a rotatable knob operatively associated with the housing and the inner key;
• and
• a nose cone connected to a distal end of the inner key, the inner key connecting the nose cone and the housing, the nose cone comprising a guide tip, the nose cone being configured to rotate when the rotatable knob rotates.

A catheter device comprising:

• a housing;
• an inner key extending distally from the housing;
• and
• a nose cone connected to a distal end of the inner key, the nose cone comprising a flex guide having one or more cut-outs or one or more bellows to control the flexibility or column strength of the flex guide.

A method for advancing a guide tip through an arterial wall defining a lumen using a catheter device, the catheter device including a housing with an actuator movably disposed therein and a button associated with the actuator, the method comprising:

• introducing a catheter having an inner key within a lumen of a patient on a first side of an occlusion within the lumen, wherein the inner key couples with the actuator;
• navigating around the occlusion within the lumen to a second side of the occlusion with the catheter;
• and
• advancing the guide tip through the arterial wall and into the lumen on the second side of the occlusion by moving the button in a first direction relative to the housing, the inner key being configured to move in a section direction upon movement of the button in the first direction, thereby advancing the guide tip.
