## Abstract

An injector including at least one fluid reservoir having a needle, a surface attached to skin and coupled to the fluid reservoir by at least a first joint and a second joint at least a portion of one of the joints being slidable or having interlocking arms. At least a portion of a path of translation of a slidable portion of the first joint and a portion of a path of translation of the second joint are angled in respect to each another.

## Claims

### Claim 1

A method of injection, comprising:
rotating a needle connected to a fluid reservoir relative to a surface configured for attachment to skin about a first joint;
concurrently moving the needle along a translational degree of freedom of each of the first joint and a second joint; and
inserting at least a portion of the needle across a surface of skin;
wherein the concurrently rotating and translating the needle converts a curvilinear travel path of the needle into at least a portion of the needle crossing the surface within less than 5 degrees deviated from a straight line.

### Claim 2 (depends on 1)

The method according to claim 1, wherein inserting at least a portion of the needle across the surface of skin is angled at less than 3 degrees from the straight line.

### Claim 3 (depends on 1)

The method according to claim 1, wherein inserting at least a portion of the needle across the surface of skin is angled at less than 1 degree from the straight line.

### Claim 4 (depends on 2)

The method according to claim 2, wherein the translational degree of freedom of one of the first and second joints is axial with respect to the surface of skin.

### Claim 5 (depends on 4)

The method according to claim 4, wherein the movement in the translational degree of freedom of one of the first and second joints is in a back and forth direction.

### Claim 6 (depends on 2)

The method according to claim 2, wherein the concurrently rotating and moving the needle comprises adjusting a path of travel and/or angle of tilt of the needle entering the skin.

### Claim 7 (depends on 6)

The method according to claim 6, further comprising forming an entry hole in the surface of skin with a diameter (Φ) being at least twice the diameter (Φ′) of the needle.

### Claim 8 (depends on 1)

The method according to claim 1, wherein at least a portion of the needle is resilient.

### Claim 9 (depends on 1)

The method according to claim 1, wherein at least a portion of the needle is curved.

### Claim 10

A method of injection, comprising:
rotating a needle connected to a fluid reservoir relative to a surface configured for attachment to skin about a first joint;
concurrently moving the needle along a translational degree of freedom of each of the first joint and a second joint; and
inserting at least a portion of the needle across a surface of skin;
forming an entry hole in the surface of skin with a diameter (Φ) being at least 1.5 times the diameter (Φ′) of the needle.

### Claim 11 (depends on 10)

The method according to claim 10, wherein inserting at least a portion of the needle across the surface of skin is angled at less than 5 degrees from the straight line.

### Claim 12 (depends on 10)

The method according to claim 10, wherein inserting at least a portion of the needle across the surface of skin is angled at less than 3 degrees from the straight line.

### Claim 13 (depends on 10)

The method according to claim 10, wherein the translational degree of freedom of one of the first and second joints is axial with respect to the surface of skin.

### Claim 14 (depends on 13)

The method according to claim 13, wherein the movement in the translational degree of freedom of one of the first and second joints is in a back and forth direction.

### Claim 15 (depends on 13)

The method according to claim 13, wherein the concurrently rotating and moving the needle comprises adjusting a path of travel and/or angle of tilt of the needle entering the surface of skin.

### Claim 16 (depends on 15)

The method according to claim 15, wherein the formed entry hole in the skin has a diameter (Φ) being at least twice the diameter (Φ′) of the needle.

### Claim 17 (depends on 10)

The method according to claim 10, wherein at least a portion of the needle is resilient.

### Claim 18 (depends on 10)

The method according to claim 10, wherein at least a portion of the needle is curved.
