Title: The Innovative Contributions of John Hardy Ashton
Introduction
John Hardy Ashton is a notable inventor based in Glendora, California, with a remarkable portfolio of 11 patents. His work primarily focuses on advancements in medical technology, particularly in the field of catheterization and electrocardiogram systems. Ashton's inventions have significantly contributed to improving medical procedures and patient care.
Latest Patents
One of Ashton's latest patents involves an electrocardiogram noise reduction system. This invention includes methods and systems of catheterization that feature a flexible catheter designed for insertion into the heart of a living subject. The catheter is equipped with a lumen for passing an electrically conductive fluid, propelled by a peristaltic pump. A fluid reservoir connected to the lumen supplies the fluid to the catheter, while electrocardiogram circuitry monitors the heart's electrical activity. An electrically conductive cable diverts induced charges in the fluid from the catheter electrodes, enhancing the accuracy of the readings.
Another significant patent is a catheter utilizing optical spectroscopy for measuring tissue contact area. This catheter comprises an elongated body, a control handle, and a hollow tip electrode with a radially-symmetrical shell. The shell defines a cavity from which light is emitted to interact with tissue and fluid outside the shell. The light reflected by tissue and absorbed by fluid is analyzed to determine the contact between the tip electrode and tissue. This innovative approach may also employ fluorescence to differentiate between tissue and blood based on their varying properties at different wavelengths.
