    • A surgical implant device for treating glaucoma includes an elongate duct structure formed from a material comprising polyisobutylene and a glassy segment. The material of the elongate duct structure preferably has a general block structure with a central elastomeric polyolefinic block and thermoplastic end blocks (e.g., a triblock polymer backbone comprising polystyrene-polyisobutylene-polystyrene). The elongate duct structure provides a fluid passageway for diverting aqueous humor from the anterior chamber of the eye. Preferably, the elongate duct structure defines a lumen channel having an inside diameter between 0.05 mm and 0.3 mm. The material of the elongate duct structure is biocompatible and biostable. Moreover, the material will not encapsulate in the eye and thus provides an unobstructed flowpath that diverts aqueous humor from the anterior chamber. Different embodiments of the implant device divert the aqueous humor to different parts of the eye (e.g., a space between the conjuctiva and sclera, Schlemm's canal, or a fluid reservoir formed on a posterior surface of the eye).
    • 用于治疗青光眼的手术植入装置包括由包含聚异丁烯和玻璃状段的材料形成的细长管道结构。 细长管道结构的材料优选具有中央弹性聚烯烃嵌段和热塑性端嵌段(例如,包含聚苯乙烯 - 聚异丁烯 - 聚苯乙烯的三嵌段聚合物主链)的通用嵌段结构。 细长的管道结构提供用于将房水从眼睛的前房转向的流体通道。 优选地,细长管道结构限定了具有在0.05mm和0.3mm之间的内径的管腔通道。 细长管道结构的材料是生物相容性和生物稳定性。 此外,该材料将不会包封在眼睛中,从而提供将房水从前房转移的畅通的流路。 植入装置的不同实施例将房水转移到眼睛的不同部分(例如,结膜和巩膜之间的空间,施莱姆氏管或形成在眼后表面上的流体储存器)。
