Patent Overview
Title and Abstract
The patent describes biocompatible intraocular implants that include a prostamide component and a biodegradable polymer. These implants are designed to facilitate the release of the prostamide, which helps in reducing intraocular pressure, a key factor in treating glaucoma and other ocular hypertension conditions[4].
Scope of the Patent
Technical Field
The patent falls within the technical field of ophthalmic medical devices, specifically focusing on intraocular implants. It addresses the need for effective and biodegradable solutions to manage ocular hypertension.
Background of the Invention
The background section highlights the limitations of existing intraocular implants, such as the need for surgical removal after the drug is released. The new invention aims to overcome these limitations by using biodegradable polymers that eliminate the need for surgical removal[4].
Claims of the Patent
Independent Claims
The patent includes several independent claims that define the scope of the invention. These claims focus on the composition of the implant, including the biodegradable polymer and the prostamide component. For example, Claim 1 describes an intraocular implant comprising a biodegradable polymer matrix and a prostamide, such as bimatoprost, dispersed within the matrix[4].
Dependent Claims
Dependent claims further specify the characteristics of the biodegradable polymer, the method of manufacturing the implant, and the therapeutic effects of the prostamide. These claims provide a detailed description of how the implant is designed to release the drug over time and how it interacts with the ocular environment[4].
