## Abstract

A drug delivery system is for injecting a medicament. The drug delivery system includes a housing, a needle having a sharp, and a barrier apparatus. The sharp is configured to move into and out of the housing. The barrier apparatus has a barrier configured to protectively surround at least the sharp of the needle, and a pull tab. The pull tab includes a connecting portion connected to the barrier, a gripping portion located apart from the connecting portion and at least partially external with respect to the housing, and a body portion extending between the connecting portion and the gripping portion. The body portion has a flexible portion for reducing strain on the barrier.

## Claims

### Claim 1

A drug delivery system for injecting a medicament, the drug delivery system comprising:
a housing;
a needle having a sharp, the sharp being configured to move into and out of the housing; and
a barrier apparatus comprising:
a barrier configured to protectively surround at least the sharp of the needle, and
a pull tab comprising:
a connecting portion connected to the barrier,
a gripping portion disposed apart from the connecting portion and at least partially external with respect to the housing, and
a body portion extending between the connecting portion and the gripping portion,
wherein the body portion has a flexible portion for reducing strain on the barrier.

### Claim 2 (depends on 1)

The drug delivery system according to claim 1, wherein the flexible portion is more flexible than the connecting portion and the gripping portion.

### Claim 3 (depends on 2)

The drug delivery system according to claim 2, wherein the flexible portion extends from at or about the connecting portion to at or about the gripping portion.

### Claim 4 (depends on 3)

The drug delivery system according to claim 3, wherein the flexible portion is a segmented tube.

### Claim 5 (depends on 3)

The drug delivery system according to claim 3, wherein the flexible portion is a webbed portion.

### Claim 6 (depends on 3)

The drug delivery system according to claim 3, wherein the flexible portion is a coiled portion.

### Claim 7 (depends on 3)

The drug delivery system according to claim 3, wherein the flexible portion is a stretchable straight segment.

### Claim 8 (depends on 1)

The drug delivery system according to claim 1, wherein the gripping portion has a base having a first diameter; and wherein the connecting portion has a second diameter less than the first diameter.

### Claim 9 (depends on 8)

The drug delivery system according to claim 8, wherein the gripping portion further comprises a protrusion and a frusto-conical shaped portion extending between the base and the protrusion.

### Claim 10 (depends on 8)

The drug delivery system according to claim 8, wherein the body portion has a third diameter less than the first diameter and the second diameter.

### Claim 11 (depends on 1)

The drug delivery system according to claim 1, further comprising a removal component, the gripping portion attached to the removal component.

### Claim 12 (depends on 1)

The drug delivery system according to claim 1, wherein the barrier comprises a cylindrical-shaped surface and an internal ledge extending radially inwardly from the cylindrical-shaped surface; wherein the needle extends through the internal ledge; and wherein the internal ledge engages the needle.

### Claim 13 (depends on 1)

The drug delivery system according to claim 1, wherein the barrier comprises an elongated portion and a generally planar portion extending from the elongated portion of the barrier and being disposed generally perpendicular with respect to a longitudinal axis of the needle.

### Claim 14 (depends on 1)

The drug delivery system according to claim 1, further comprising a removal component having a serrated portion, wherein the gripping portion is attached to the removal component by the serrated portion.

### Claim 15 (depends on 1)

The drug delivery system according to claim 1, wherein the barrier comprises an elastomeric sleeve for maintaining the sterility of the needle.

### Claim 16

A barrier apparatus for a drug delivery system, the drug delivery system comprising a housing and a needle having a sharp, the sharp being configured to move into and out of the housing, the barrier apparatus comprising:
a barrier configured to protectively surround at least the sharp of the needle; and
a pull tab comprising:
a connecting portion connected to the barrier,
a gripping portion disposed apart from the connecting portion and configured to be disposed at least partially external with respect to the housing, and
a body portion extending between the connecting portion and the gripping portion,
wherein the body portion has a flexible portion for reducing strain on the barrier.

### Claim 17 (depends on 16)

The barrier apparatus according to claim 16, wherein the barrier and the pull tab are a unitary component made from one single piece of material.

### Claim 18 (depends on 16)

The barrier apparatus according to claim 16, wherein the connecting portion is connected to the barrier by a press-fit mechanism.

### Claim 19 (depends on 16)

The barrier apparatus according to claim 16, wherein the barrier is substantially enclosed by the connecting portion of the pull tab.

### Claim 20

A pull tab for a barrier apparatus of a drug delivery system, the barrier apparatus comprising a barrier, the pull tab comprising:
a connecting portion configured to be connected to the barrier;
a gripping portion disposed apart from the connecting portion; and
a body portion extending between the connecting portion and the gripping portion,
wherein the body portion has a flexible portion for reducing strain on the barrier.
