Title: Timothy Dominic Logsdon and Burst-Mode Intravascular Lithotripsy

Introduction

Timothy Dominic Logsdon is an inventor associated with Livermore, California, and Shockwave Medical, Inc. His patent work concerns intravascular lithotripsy (IVL), a technology that uses shock waves to address calcified material within blood vessels. The available information identifies 1 patent associated with him.

Latest Patents

Logsdon’s patent, “Burst Mode Operation of Intravascular Lithotripsy (IVL),” describes systems and methods for applying voltage across electrodes in a shock-wave catheter. The electrodes can be activated using packets containing multiple sub-pulses delivered in rapid succession. The disclosure gives example sub-pulse frequencies of 100 Hz to 10 kHz, pulse widths of one microsecond or shorter, and peak power of 250 kW or higher. Packets may be delivered in bursts at frequencies such as 1 to 4 Hz, with the interval between sub-pulses shorter than the interval between packets.

The patent also describes sub-pulses with higher peak power and lower energy than non-burst pulses. A single-stage or multi-stage generator circuit may supply the voltages, and the catheter may operate in either burst or non-burst mode.

Career Highlights

Logsdon’s listed work connects him with Shockwave Medical, Inc., a company focused on intravascular lithotripsy technology. His patent disclosure addresses the electrical pulse patterns used to activate catheter electrodes, including how bursts and sub-pulses can be configured.
