Abstract
The invention discloses a trabecular stent and methods for treating glaucoma. The stent may incorporate an intraocular pressure sensor comprising a compressible element that is implanted inside an anterior chamber of an eye, wherein at least one external dimension of the element correlates with intraocular pressure. In some embodiments, the sensor may be coupled to the stent. Also disclosed are methods of delivery of the stent and the sensor to the eye.
Claims10
A method of treating and monitoring of glaucoma, the method comprising:
- providing a delivery device configured to be inserted into an eye of a patient;
- providing at least one implant, the implant configured to be held within the delivery device, and the implant comprising:
- an inlet and an outlet section, the inlet section being in fluid communication with the outlet section and configured to conduct fluid from an anterior chamber of the eye to Schlemm's canal of the eye;
- providing a sensor element configured to measure intraocular pressure and configured to be held within the delivery device;
- positioning the at least one implant in the eye such that an end of the inlet section is in the anterior chamber of the eye and an end of the outlet section is in Schlemm's canal;
- positioning the sensor element completely within the anterior chamber of the eye to measure the intraocular pressure of the eye;
- and
- anchoring, from within the anterior chamber, the sensor element to eye tissue such that the sensor element is spaced apart from the implant.
5 more elements
A method of monitoring intraocular pressure comprising:
- providing a delivery device configured to be inserted into at least an anterior chamber of an eye of a patient;
- providing at least one implant, the implant being held within the delivery device and comprising a proximal end portion and a distal end portion;
- providing a sensor element configured to measure intraocular pressure and being held within the delivery device;
- inserting the delivery device into the anterior chamber;
- positioning the at least one implant in the eye such that the distal end portion of the implant extends through eye tissue and the proximal end portion is disposed within the anterior chamber;
- positioning the sensor element completely within the anterior chamber of the eye to measure the intraocular pressure of the eye;
- substantially fixing, from within the anterior chamber, the sensor element to ocular tissue such that the sensor element is spaced apart from the implant;
- and
- conducting aqueous humor through the implant from the anterior chamber to a physiologic outflow pathway.
