摘要: A trabecular pump is implantable in the eye to reduce intraocular pressure. The pump drains aqueous humor from the anterior chamber into outflow pathways, such as Schlemm's canal. A feedback system includes an intraocular pump and a pressure sensor in communication with the pump, for regulating intraocular pressure.

摘要: Implants and methods for treating ocular disorders are provided. One method involves introducing an implant into an anterior chamber of an eye such that at least a distal end of the implant is temporarily in the anterior chamber. The implant is implanted into eye tissue adjacent the anterior chamber. A therapeutic agent is eluted from the implant into at least one of the anterior chamber, a physiologic outflow pathway of the eye, and a space adjacent a choroid of the eye. The therapeutic agent can be an antiproliferative agent, an anti-inflammatory drug, or a compound for treating glaucoma or ocular hypertension. The therapeutic agent can be contained within the implant or coated on the implant.

摘要: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.

摘要: Methods and implants for treating glaucoma in an eye are described. The implant includes an inlet section configured to be positioned in the anterior chamber of the eye and an outlet section in fluid communication with the inlet section. The outlet section is configured to be positioned in Schlemm's canal of the eye. The implant comprises a hydrogel and is configured to conduct aqueous humor from the anterior chamber to Schlemm's canal.

摘要: Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involve bypassing diseased trabecular meshwork with the use of a seton implant. The seton implant is used to prevent a healing process known as filling in, which has a tendency to close surgically created openings in the trabecular meshwork. The surgical method and novel implant are addressed to the trabecular meshwork, which is a major site of resistance to outflow in glaucoma. In addition to bypassing the diseased trabecular meshwork at the level of the trabecular meshwork, existing outflow pathways are also used or restored. The seton implant is positioned through the trabecular meshwork so that an inlet end of the seton implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.
