Abstract
Microcannulae are constructed with multiple components in a composite design, allowing the microcannulae to have varying mechanical and delivery properties that will enable ophthalmic treatments by minimally invasive means. The microcannula includes at least one flexible, tubular communicating element with an outer diameter of 350 microns or less, a proximal connector for introduction of materials, energy or tools. It may also include a reinforcing member attached to the communicating element, which may be designed to create variable stiffness along the length of the microcannula. The microcannula may also include other features such as a signal beacon near the distal tip.
