Patent number: 11955765Abstract: Techniques are provided for controlling an output laser pulse signal of a medical device. A control device defines a time duration of capacitive discharge to a laser device. The time duration corresponds to an intended energy of the output laser pulse signal. The control device generates a plurality of sub-pulse control signals. The sub-pulse control signals define a series of capacitive discharge events of the capacitor bank. The control device modulates one or more of a sub-pulse control signal period or a sub-pulse time duration of the sub-pulse control signals to modify the capacitive discharge of the capacitor bank to the laser device during the time duration.Type: GrantFiled: September 25, 2020Date of Patent: April 9, 2024Assignee: Boston Scientific Scimed, Inc.Inventors: Jian James Zhang, Baocheng Yang, Xirong Yang, Hyun Wook Kang, Brian Cheng, Peter Bull, Rongwei Jason Xuan, Thomas C.
