## Abstract

A delivery system is disclosed which can be used to deliver an ocular implant into a target location within the eye via an ab interno procedure. In some embodiments, the implant can provide fluid communication between the anterior chamber and the suprachoroidal or supraciliary space while in an implanted state. The delivery system can include a proximal handle component and a distal delivery component. In addition, the proximal handle component can include an actuator to control the release of the implant from the delivery component into the target location in the eye.

## Claims

### Claim 1

A delivery system for delivering an ocular implant into an eye, the delivery system comprising:
a proximal handle portion;
a delivery portion coupled to the handle portion, the delivery portion configured to releasably couple to an ocular implant, the delivery portion including a guidewire that fits through an inner lumen of the ocular implant;
wherein the guidewire includes at least one curved section for providing an interference fit between the guidewire and an inner lumen of the ocular implant when the ocular implant is mounted on the guidewire to assist in retaining the implant on the guidewire during delivery into the eye.

### Claim 2 (depends on 1)

The delivery system of claim 1, wherein the delivery portion further includes a sheath positioned axially over at least a portion of the guidewire.

### Claim 3 (depends on 1)

The delivery system of claim 1, further comprising an actuator that actuates to cause an ocular implant coupled to the delivery portion to release from the delivery portion upon actuation of the actuator.

### Claim 4 (depends on 1)

The delivery system of claim 1, wherein the guidewire comprises an s-shape.

### Claim 5 (depends on 1)

The delivery system of claim 1, wherein the guidewire comprises a sinusoidal curve shape.

### Claim 6 (depends on 1)

The delivery system of claim 1, wherein the curved section of the guidewire is confined along a discrete section of the guidewire such that the discrete section of the guidewire forms a radius of curvature that is tighter than a radius of curvature of the entire guidewire.

### Claim 7 (depends on 3)

The delivery system of claim 3, wherein, when the implant has been delivered into the eye, actuation of the actuator causes the guidewire to withdraw from the ocular implant in a proximal direction.

### Claim 8 (depends on 7)

The delivery system of claim 7, wherein the delivery portion further includes a sheath positioned axially over at least a portion of the guidewire and wherein a distal end of the sheath abuts a proximal end of an ocular implant when the ocular implant is positioned on the guidewire, and wherein the distal end of the sheath prevents the ocular implant from moving toward the handle portion as the guidewire withdraws in a proximal direction.

### Claim 9 (depends on 1)

The delivery system of claim 1, wherein the guidewire comprises at least two curved sections, the curved sections being spaced from one another a distance of about 0.0100 inch to 0.0200 inch along the length of the guidewire.

### Claim 10 (depends on 1)

The delivery system of claim 1, wherein the guidewire includes at least one inner lumen.

### Claim 11 (depends on 10)

The delivery system of claim 10, wherein the guidewire includes at least one opening that provides fluid communication between the inner lumen of the guidewire and an area surrounding the guidewire.

### Claim 12 (depends on 11)

The delivery system of claim 11, wherein the area surrounding the guidewire comprises an inner lumen of an ocular implant.

### Claim 13 (depends on 1)

The delivery system of claim 1, wherein the delivery system includes at least one fluid delivery feature which delivers fluid from a fluid source and into an inner lumen of the guidewire.

### Claim 14 (depends on 13)

The delivery system of claim 13, wherein the fluid from the fluid source includes one or more of a viscoelastic, a drug and a stem cell.

### Claim 15 (depends on 1)

The delivery system of claim 1, further comprising an ocular implant formed of a tubular structure having an internal lumen.

### Claim 16 (depends on 1)

The delivery system of claim 1, wherein the ocular implant is configured to drain fluid from an anterior chamber of an eye to a supraciliary space of an eye.

### Claim 17 (depends on 1)

The delivery system of claim 1, wherein a distal portion of the guidewire is configured to separate a ciliary body of the eye from a sclera of the eye.

### Claim 18 (depends on 3)

The delivery system of claim 3, wherein the actuator includes a mechanism that includes a spring, the spring being coupled to the guidewire.

### Claim 19 (depends on 18)

The delivery system of claim 18, wherein actuation of the actuator causes the spring to move the guidewire between a first position and a second position relative to the handle portion.

### Claim 20 (depends on 18)

The delivery system of claim 18, wherein actuation of the actuator causes the spring to move the guidewire in a distal direction relative to the handle portion.

### Claim 21 (depends on 18)

The delivery system of claim 18, wherein actuation of the actuator causes the spring to move the guidewire in a proximal direction relative to the handle portion.

### Claim 22 (depends on 1)

The delivery system of claim 1, wherein the curved portion of the guidewire has a nominal longitudinal axis and one or more wire peaks separated from the nominal longitudinal axis, wherein each of the peaks contacts an inner surface of the ocular implant to assist in retaining the implant on the guidewire during delivery into the eye.
