## Abstract

A catheter insertion device includes a housing, a needle coupled to a needle hub, a catheter pre-disposed over the needle, a guidewire pre-disposed in a lumen of the needle, a guidewire advancement assembly configured to distally advance the guidewire with respect to the needle, and a catheter advancement assembly configured to distally advance the catheter with respect to the needle. The needle hub can be fixed to an interior of the housing with a distal section of the needle extending from the housing. The catheter advancement assembly can include a tail portion to engage the needle hub in order to prevent movement of the catheter advancement assembly. The catheter insertion device can also include a flash indicator with an elongate channel in fluid communication with the needle lumen. The elongate channel can include a viewable pathway to indicate to a user that the needle tip is within a blood vessel.

## Claims

### Claim 1

A catheter insertion device, comprising:
a housing;
a needle coupled to a needle hub, the needle hub fixed to an interior of the housing, a distal section of the needle extending from the housing;
a catheter pre-disposed over the needle;
a guidewire pre-disposed in a lumen of the needle;
a guidewire advancement assembly configured to distally advance the guidewire with respect to the needle;
a catheter advancement assembly configured to distally advance the catheter with respect to the needle, the catheter advancement assembly comprising a tail portion comprising a first spring arm and a second spring arm, the first spring arm including a first notch, the second spring arm including a second notch, the first notch and the second notch cooperating to engage the needle hub to prevent movement of the catheter advancement assembly; and
a flash indicator including an elongate channel in fluid communication with the needle lumen, the elongate channel including a viewable pathway.

### Claim 2 (depends on 1)

The catheter insertion device according to claim 1, wherein the guidewire advancement assembly is configured to disengage the tail portion of the catheter advancement assembly from the needle hub when the guidewire is distally advanced.

### Claim 3 (depends on 2)

The catheter insertion device according to claim 2, wherein the guidewire advancement assembly comprises an actuation block configured to contact the first spring arm and the second spring arm to disengage the first notch and the second notch from the needle hub.

### Claim 4 (depends on 3)

The catheter insertion device according to claim 3, wherein the first spring arm and the second spring arm each include a slanted surface configured for contact with the actuation block to disengage the tail portion of the catheter advancement assembly from the needle hub.

### Claim 5 (depends on 1)

The catheter insertion device according to claim 1, wherein the elongate channel is in fluid communication with the needle via an access point defined by a portion of the catheter advancement assembly.

### Claim 6 (depends on 5)

The catheter insertion device according to claim 5, wherein the elongate channel extends from the catheter advancement assembly to a portion of the housing.

### Claim 7 (depends on 5)

The catheter insertion device according to claim 5, wherein a portion of the pathway is included on a finger pad portion of the catheter advancement assembly.

### Claim 8 (depends on 1)

The catheter insertion device according to claim 1, wherein the pathway defines a tortuous path.

### Claim 9

The catheter insertion device according to 1, wherein the elongate channel is included in a translucent portion of the catheter insertion device.

### Claim 10

The catheter insertion device according to 1, wherein the guidewire advancement assembly includes a slide member coupled to the guidewire, the guidewire having a distal end in the lumen of the needle in a slide member first position, the guidewire moving distal of the distal end of the needle in a slide member second position, the slide member second position being distal of the slide member first position.

### Claim 11 (depends on 1)

The catheter insertion device according to claim 1, wherein the catheter advancement assembly further comprises a head portion including a cover connected to opposing wings, the cover spanning an exterior of the housing and the wings extending from opposing sides of the housing when the first notch and the second notch of the tail portion are engaged with the needle hub.

### Claim 12 (depends on 11)

The catheter insertion device according to claim 11, wherein the opposing wings each include a series of ridges configured to assist gripping of the opposing wings.

### Claim 13 (depends on 11)

The catheter insertion device according to claim 11, wherein the cover includes a contoured surface configured to assist engagement of the catheter advancement assembly.

### Claim 14 (depends on 11)

The catheter insertion device according to claim 11, wherein the opposing wings are disposed in a gap between a top portion of the housing and a bottom portion of the housing.

### Claim 15 (depends on 1)

The catheter insertion device according to claim 1, wherein a proximal end of the guidewire is secured to the housing, and wherein an intermediate portion of the guidewire includes a U-shaped bend.

### Claim 16 (depends on 1)

The catheter insertion device according to claim 1, wherein the catheter includes a catheter hub, the catheter advancement assembly removably attached to the catheter hub, wherein a valve is removably included in the catheter hub, and wherein a safety housing is removably disposed in the valve.

### Claim 17 (depends on 1)

The catheter insertion device according to claim 1, wherein the guidewire advancement assembly includes a spring arm designed to engage with a pocket in the housing to prevent proximal retraction of the guidewire after full distal advancement of the guidewire.

### Claim 18 (depends on 17)

The catheter insertion device according to claim 17, wherein the spring arm is disposed on a guidewire lever, and wherein the pocket is included in the needle hub.

### Claim 19 (depends on 18)

The catheter insertion device according to claim 18, wherein the catheter advancement assembly includes a safety housing, a needle safety component disposed within the safety housing, and wherein distal movement of the safety housing enables a free end of the spring arm to seat in the pocket of the needle hub after full distal advancement of the guidewire.

### Claim 20 (depends on 19)

The catheter insertion device according to claim 19, wherein the catheter advancement assembly is configured such that proximal movement of the safety housing to a position adjacent the needle hub pushes the free end of the spring arm out of the pocket of the needle hub to enable guidewire advancement and retraction.
