Flow regulating implant, method of manufacture, and delivery device
First Claim
1. A method for manufacturing an implant comprising the steps of:
- selecting a first tube having a longitudinal bore and a second tube having a longitudinal bore and dimensioned to fit inside the longitudinal bore of the first tube;
placing the second tube inside the longitudinal bore of the outer tube;
cutting the first tube and the second tube to form the implant.

Abstract
An implant includes a tube for permitting fluid flow. A flow controlling rod may be inserted within the tube passage. One or more holes around the circumference of the tube may be selectively permanently or temporarily occluded to give desired flow characteristics.
A delivery device for implanting the implant may include a central bore in which a retractable wire is located. The retractable wire penetrates a tube passage of the implant when the implant is attached to the delivery device. A hook on the delivery device prevents the implant from moving down the wire. After the implant is in position in the eye, the retention wire is retracted out of the implant. With the retention wire retracted, the implant is then free to slide away from the hook, allowing the delivery device to be withdrawn, leaving the implant in place.
In a method for manufacturing an implant, two tubes of different diameters are utilized. The smaller tube fits inside the longitudinal bore of the larger tube. When the tubes are cut, the smaller tube forms the tube of the implant and the remaining portions of the larger tube form the retention projection and/or disk of the implant.
