United States Patent 8,025,635: A Detailed Analysis of Scope and Claims
Introduction
United States Patent 8,025,635, titled "DEVICE AND METHODS FOR TREATING PARANASAL SINUS CONDITIONS," was granted on September 27, 2011, to Intersect ENT, Inc. This patent is significant in the medical field, particularly in the treatment of paranasal sinus conditions. Here, we will delve into the scope, claims, and the broader patent landscape surrounding this invention.
Background and Invention Overview
The patent describes a device and methods for treating paranasal sinus conditions, such as chronic sinusitis. The invention involves the use of a stent or other implantable device designed to maintain the patency of the paranasal sinuses and facilitate the drainage of mucus and other fluids[1].
Scope of the Patent
The scope of the patent encompasses various aspects of the device and its application:
- Device Design: The patent details the design of the stent, including its material composition, shape, and dimensions. It emphasizes the importance of the device's ability to expand and maintain the sinus ostia open[1].
- Methods of Use: The patent includes methods for implanting the device, which involve minimally invasive procedures to ensure the sinus ostia remain open, thereby improving sinus drainage[1].
- Therapeutic Applications: The invention is intended for treating various paranasal sinus conditions, including chronic sinusitis, by ensuring proper drainage and reducing inflammation[1].
Claims of the Patent
The patent includes multiple claims that define the scope of the invention:
- Independent Claims: These claims define the core aspects of the invention, such as the design of the stent and the methods for its implantation[1].
- For example, Claim 1 describes a "device for treating a paranasal sinus condition, comprising a stent configured to be implanted in a sinus ostium to maintain patency of the sinus ostium"[1].
- Dependent Claims: These claims build upon the independent claims, providing additional details and variations of the invention. They may include specific materials, dimensions, or additional features of the stent[1].
Key Components of the Claims
- Stent Design: The claims specify the stent's structure, including its shape, material, and the mechanism by which it expands to maintain the sinus ostium open[1].
- Implantation Method: The claims describe the procedure for implanting the stent, ensuring it is securely positioned in the sinus ostium[1].
- Therapeutic Effects: The claims highlight the therapeutic benefits of the device, such as improved sinus drainage and reduced inflammation[1].
