## Abstract

A catheter hub assembly. The catheter hub assembly includes a catheter hub body, a septum and a septum retainer, the catheter hub body having a distal end, a proximal and an internal wall defining an internal fluid passageway therebetween, the internal wall defining a transitional step within the internal fluid passageway, the septum positioned within the internal fluid passageway such that a distal end of the septum abuts up against the transitional step, the septum retainer at least partially receivable within the internal fluid passageway and having an outer wall shaped and sized to interlock with the inner wall of the catheter hub body, the outer wall including one or more lateral ribs configured to inhibit rotation of the septum retainer relative to the catheter hub body.

## Claims

### Claim 1

A catheter assembly configured for insertion into the vein of a subject, comprising:
a catheter hub having a catheter hub distal end operably coupled to a catheter and a catheter hub proximal end configured to be operably coupled to an insertion device;
a pair of flexible wings extending radially from the catheter hub, the wings having a wings bottom surface;
a heel portion having a heel portion bottom surface extending from a proximal end of the pair of flexible wings towards the catheter hub proximal end, and
a collar at least partially wraps around a proximal portion of the catheter hub;
wherein the wings bottom surface and the heel portion bottom surface form a contiguous surface that is angled relative to the catheter such that the catheter remains in a substantially straight line configuration without significant bending when inserted into the vein of the subject with the contiguous surface being substantially parallel to the skin of the subject.

### Claim 2 (depends on 1)

The catheter assembly of claim 1, wherein the contiguous surface is offset from the axis of the catheter by an angle in the range between seven and nine degrees.

### Claim 3 (depends on 1)

The catheter assembly of claim 1, wherein the contiguous surface is offset from the axis of the catheter by an angle of approximately eight degrees.

### Claim 4 (depends on 1)

The catheter assembly of claim 1, wherein a distal portion of the pair of wings forms a substantially straight line extending substantially orthogonal to the catheter for making contact with the skin of the subject.

### Claim 5 (depends on 1)

The catheter assembly of claim 1, wherein a top surface of the pair of wings defines a concave surface configured to aid a clinician in gripping the catheter hub.

### Claim 6 (depends on 1)

The catheter assembly of claim 1, wherein the wings have a lower modulus of elasticity than the catheter hub.

### Claim 7 (depends on 1)

The catheter assembly of claim 1, wherein a textured pattern is formed into the contiguous surface to increase a frictional resistance with the skin of the subject when the catheter is inserted into the vein of the subject.

### Claim 8 (depends on 1)

The catheter assembly of claim 1, wherein the wings are integrally molded onto the catheter hub.

### Claim 9 (depends on 1)

The catheter assembly of claim 1, wherein the collar wraps around a central axis of the catheter hub.

### Claim 10 (depends on 1)

The catheter assembly of claim 1, wherein the catheter hub includes one or more ledges to provide bonding surfaces onto which the pair of wings are molded to provide structural reinforcement for the pair of flexible wings.

### Claim 11

Apparatus, comprising:
an insertion device having a needle assembly and a needle housing, the needle assembly including a needle having a distal needle tip, the needle assembly operably coupled to the needle housing and shiftable between a ready for use position in which the needle tip extends from the needle housing, and a safe position in which the needle tip is housed within the needle housing;
a catheter hub having an extension tube, a distal end to which a catheter is operably coupled and a proximal end configured to be operably coupled to the insertion device; and
a wing assembly operably coupled to the catheter hub, the wing assembly including a pair of flexible wings having a wings bottom surface extending radially from the catheter hub, a heel portion having a heel portion bottom surface extending from a proximal end of the pair of flexible wings towards the proximal end of the catheter hub, and a collar at least partially wrapping around a proximal portion of the catheter hub, wherein the bottom surface of the pair of wings and the bottom surface of the heel portion form a contiguous surface that is angled relative to the catheter such that the catheter remains in a substantially straight line configuration without significant bending when inserted into a vein of a subject with the contiguous surface being substantially parallel to the skin of the subject.

### Claim 12 (depends on 11)

Apparatus of claim 11, wherein the contiguous surface is offset from the axis of the catheter by an angle in the range of between seven and nine degrees.

### Claim 13 (depends on 11)

Apparatus of claim 11, wherein the contiguous surface is offset from the axis of the catheter by an angle of approximately eight degrees.

### Claim 14 (depends on 11)

Apparatus of claim 11, wherein a distal portion of the pair of wings forms a substantially straight line extending substantially orthogonal to the catheter for making contact with the skin of the subject.

### Claim 15 (depends on 11)

Apparatus of claim 11, wherein a top surface of the pair of wings defines a concave surface configured to aid a clinician in gripping the catheter hub.

### Claim 16 (depends on 11)

Apparatus of claim 11, wherein the wings have a lower modulus of elasticity than the catheter hub.

### Claim 17 (depends on 11)

Apparatus of claim 11, wherein a textured pattern is formed into the contiguous surface to increase a frictional resistance with the skin of the subject when the catheter is inserted into vein of the subject.

### Claim 18 (depends on 11)

Apparatus of claim 11, wherein the wings are integrally molded onto the catheter hub.

### Claim 19 (depends on 11)

Apparatus of claim 11, wherein the collar wraps around a central axis of the catheter hub.

### Claim 20 (depends on 11)

Apparatus of claim 11, wherein the catheter hub includes one or more ledges to provide a bonding surface onto which the wings are molded to provide structural reinforcement for the pair of flexible wings.
