Publication number: 20240115314Abstract: Provided herein are systems, devices, and methods for performing a medical procedure on a patient. The system comprises an ablation catheter comprising a shaft, at least one therapeutic element positioned on the shaft, and one or more tissue-contact sensing components configured to provide a contact signal related to the level of contact between the at least one therapeutic element and tissue. The system further comprises: an energy delivery unit configured to deliver ablative energy to the at least one therapeutic element to create a lesion in target tissue, and to provide an energy delivery data; a force module configured to receive the contact signal and provide contact data; and a processing unit configured to determine an ablation index based on both the energy delivery data and the contact data. The ablation index can represent the status of the lesion being created.Type: ApplicationFiled: February 17, 2022Publication date: April 11, 2024Inventors: Ahmad FALAHATPISHEH, Steven YON, Xinwei SHI, Haizhe ZHANG, Derrick CHOU, Timothy CORVI, Graydon Earnest BEATTY, Daniel WELSH, Alexander HIGGINS, Marcus JULIAN, R.

Patent number: 11590938Abstract: An onboard washing system provides the ability to wash specific areas at the rear of a concrete truck, without requiring an operator to climb a ladder or climb on the truck. Certain specified areas which are traditionally difficult to wash, including the inside of the charge hopper, the interior portions of the discharge chute, and rear portions of the mixing drum structure, can now be washed in an automated and efficient manner. The truck-mounted washing system has components which are specifically positioned to cause washing fluid (water) to be sprayed or directed toward predetermined areas in an efficient and effective manner. The system also includes hand-held washing wands or washing mechanisms, which allow an operator to easily reach additional zones or additional areas at the rear of the truck, which are lower. Most significantly, the truck-mounted wash systems and the hand-held nozzle systems (wand) are all operable while an operator remains on the ground.Type: GrantFiled: January 25, 2021Date of Patent: February 28, 2023Assignee: Con-Tech Manufacturing, Inc.Inventors: Grant McNeilus, Brian Meldahl, Daniel Welsh, James Cunningham
