Enhanced Ultrasound-Enhanced Delivery of Drugs for Ophthalmic Care

An improved system and method for ultrasound-enhanced delivery of drugs to intraocular spaces, featuring optimized frequency, novel geometry, real-time monitoring, and combination with micro-needles to enhance delivery efficiency and safety.

The original patent disclosed a system and method for ultrasound-enhanced delivery of drugs to intraocular spaces. However, the existing design had limitations in terms of delivery efficiency, safety, and adaptability to different types of drugs. The new inventive concept addresses these limitations by introducing novel features that optimize the ultrasound frequency, applicator geometry, and real-time monitoring to ensure more efficient and targeted drug delivery.

The enhanced system and method comprise an ultrasound-generating device designed to operate at a frequency optimized for a specific type of drug, thereby enhancing delivery efficiency. The drug applicator features a novel geometry that minimizes ultrasound attenuation, improving delivery efficiency. Additionally, the system includes a real-time monitoring module that tracks the delivery process and adjusts the ultrasound frequency and intensity in real-time, ensuring optimal delivery. Furthermore, the method can be combined with micro-needles to create micro-pores in the sclera, increasing the drug permeation rate. The new claims provide a more efficient, safe, and adaptable solution for ophthalmic care.

The new claims introduce novel features that optimize the ultrasound frequency, applicator geometry, and real-time monitoring, which are not present in the original patent. The combination of these features provides a significant improvement in delivery efficiency and safety, making the new inventive concept non-obvious and novel compared to the original patent.

Alternative embodiments of the inventive concept could include varying the geometry of the drug applicator, using different types of ultrasound transducers, or integrating additional sensors to monitor the delivery process. Variations could also include adapting the system for delivery of different types of drugs or for use in other medical applications.

The enhanced system and method for ultrasound-enhanced delivery of drugs have significant commercial potential in the ophthalmic care industry, particularly for treating diseases such as central retinal vein occlusion, branch retinal vein occlusion, and macular degeneration. The market for ophthalmic drug delivery systems is expected to grow, driven by an increasing demand for effective and safe treatments.
