Abstract
An aqueous humor drainage device having an elongate structure that provides a fluid passageway for diverting aqueous humor from the anterior chamber of the eye. The device is formed from a biocompatible soft polymeric material with a hardness less than Shore 80A. Preferably, the polymeric material includes polyisobutylene and a glassy segment. The device preferably includes at least one fixation member that extends from the elongate structure. In one embodiment, the fixation member is realized by a tab that is spaced apart from the two ends of the elongate structure. In another embodiment, the fixation member is realized by a pair of tines that extend in traverse directions relative to the central axis of the elongate structure. The tines are spaced apart for positioning on opposite sides of the sclera of the eye during use.
