Title: Qingsong Fan and Nanoparticle-Enhanced Laser Lithotripsy
Introduction
Qingsong Fan is an inventor associated with Chicago, Illinois. His patent work describes a nanoparticle-based approach to laser lithotripsy, a procedure that uses laser energy to break up obstructions within a body cavity. The available information lists 1 patent and identifies Duke University and The University of Chicago among his professional affiliations.
Latest Patents
Fan’s listed patent, “Compositions and Methods for Laser Lithotripsy Using Nanoparticle Fine-Tuned NIR Absorption,” presents systems and methods for improving how lithotripsy media absorb laser energy. The approach introduces a medium containing nanoparticles into a body cavity with target obstructions, then delivers laser energy through the medium to disrupt those obstructions.
The patent describes nanoparticles with diameters selected to enhance absorption efficiency. Examples include organic polymers such as PEDOT:PSS and inorganic compounds such as indium tin oxide. A system may combine a laser source, a fluid-delivery component for the nanoparticle-containing medium, and an optical fiber that delivers the laser energy. The described manufacturing methods include selecting target wavelengths, synthesizing nanoparticles with corresponding absorption characteristics, and dispersing them at chosen concentrations.
