## Abstract

An apparatus for deploying a needle within a lumen is provided. The apparatus includes a housing having a threaded bushing radially disposed therein. The bushing rigidly couples with a nose cone having a guide tip disposed at an end opposite the bushing for penetrating an arterial wall of a lumen. During operation, a user incrementally advances the bushing within the housing, thereby incrementally advancing the guide tip into the lumen. The nose cone also includes a flex guide having a slot configuration which couples with the guide tip which deploys into the lumen along with the guide tip.

## Claims

### Claim 1

A catheter device comprising:
a housing;
a shaft adaptor connected to the housing, the shaft adaptor comprising a rotatable guide having one or more interfaces;
an inner key extending distally from the shaft adapter, the inner key having one or more interfaces that engage the one or more interfaces of the shaft adaptor; 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 guide rotates.

### Claim 2 (depends on 1)

The catheter device of claim 1, wherein the inner key comprises a braided tube.

### Claim 3 (depends on 2)

The catheter device of claim 2, wherein the inner key is configured to rotate when the guide rotates.

### Claim 4 (depends on 2)

The catheter device of claim 2, further comprising a rotatable knob operatively associated with the housing and the inner key.

### Claim 5 (depends on 4)

The catheter device of claim 4, wherein the nose cone is configured to rotate with the rotatable knob.

### Claim 6 (depends on 2)

The catheter device of claim 2, wherein the nose cone houses a flex guide having one or more cuts to control the flexibility or column strength of the flex guide.

### Claim 7 (depends on 2)

The catheter device of claim 2, wherein the nose cone houses a flex guide having one or more bellows to control the flexibility or column strength of the flex guide.

### Claim 8

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.

### Claim 9 (depends on 8)

The catheter device of claim 8, wherein the nose cone houses a flex guide having one or more cuts to control the flexibility or column strength of the flex guide.

### Claim 10 (depends on 8)

The catheter device of claim 8, wherein the nose cone houses a flex guide having one or more bellows to control the flexibility or column strength of the flex guide.

### Claim 11 (depends on 8)

The catheter device of claim 8, the nose cone including a nose cone cam surface and the guide tip comprising a guide tip cam surface, the nose cone cam surface configured to engage with the guide tip cam surface.

### Claim 12 (depends on 8)

The catheter device of claim 8, wherein the guide tip includes at least one tip configured to penetrate body tissue.

### Claim 13 (depends on 12)

The catheter device of claim 12, wherein the guide tip includes a plurality of circumferentially spaced apart tips disposed about a periphery of the guide tip.

### Claim 14

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.

### Claim 15 (depends on 14)

### Claim 16 (depends on 14)

The guide device of claim 14, wherein the one or more bellows are spaced longitudinally along the flex guide.

### Claim 17 (depends on 14)

The guide device of claim 14, further comprising an anchoring member disposed about a braided tube coupled to the inner key.

### Claim 18 (depends on 17)

### Claim 19

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.

### Claim 20 (depends on 19)

The method as recited in claim 19, wherein moving the button engages one or more button gradients associated with the button with one or more actuator gradients associated with the actuator.

### Claim 21 (depends on 20)

The method as recited in claim 20, wherein the catheter includes a first handle and a second handle, the button remaining fixed with respect to the first handle.

### Claim 22 (depends on 21)

The method as recited in claim 21, wherein moving the button in the first direction comprises moving the button in a direction transverse to a longitudinal axis of the actuator.

### Claim 23 (depends on 22)

The method as recited in claim 22, further comprising anchoring the catheter within tissue.

### Claim 24 (depends on 23)

The method as recited in claim 23, wherein anchoring the catheter within tissue comprises deploying an anchor of an anchoring assembly, the anchor comprising a material capable of bowing.
