Delivery system for ocular implant

摘要

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.

主权项

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 retractable guidewire that fits through an inner lumen of the ocular implant such that only the guidewire is inserted through the inner lumen of the ocular implant when the ocular implant is attached to the guidewire; wherein the guidewire includes at least one non-spiraled 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, 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 and 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; 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; a dampener coupled to the handle portion, the dampener adapted to dampen retraction of the guidewire upon actuation of the actuator.
