Title: Innovations of James D. Sweeney
Introduction
James D. Sweeney is a notable inventor based in Cleveland Heights, OH (US). He has made significant contributions to the field of medical technology, particularly in the area of nerve stimulation. With a total of 3 patents, his work has advanced the understanding and application of electrical signals in nerve trunks.
Latest Patents
One of Sweeney's latest patents is the "Asymmetric shielded two electrode cuff." This invention involves a nerve trunk that has an annular electrode cuff positioned around it. The cuff is designed to impose electrical signals onto the nerve trunk, generating unidirectionally propagated action potentials. The electrode cuff features an annular cathode with a circular passage of a first diameter and an annular anode with a larger circular passage. The asymmetrical placement of the anode and cathode allows for efficient current flow, enhancing the effectiveness of the device.
Another significant patent is the "Antidromic pulse generating wave form for collision blocking." This invention includes an electrode cuff with a dielectric sleeve and an annular cathode electrode. The cathode is positioned off-center within the sleeve, allowing for a greater amplitude of electric current flow along the nerve. A signal generator applies a pulse train across the electrodes, which includes alternating pulse portions designed to ensure balanced net charge transfer.
