Ultrasound in Surgical Devices: Advances in Robotic Surgery & HIFU applications

23 September 2021 at 10 am EST / 3pm GMT

Featuring Kevin Houser, PE

Director, IP Strategy, Engineering Fellow, Intellectual Property Center of Excellence

Johnson & Johnson, Ethicon Endo-Surgery


Our next Virtual Collaborations will be a continuation of this years series of presentations and where the first three were focus on technologies and measurements, the fourth will focus in the area of applications with Kevin Houser presenting on aspect of ultrasound in surgical devices.  Kevin is an Engineering Fellow with Ethicon, a Johnson and Johnson company and has worked on ultrasonic cutting and coagulating devices used in surgery for over 20 years.  He will provide information on how ultrasound is used to create beneficial tissue effects as well as going into some of the devices and algorithms that are making ultrasound a mechanism of choice for many surgeons.  In addition he will touch on some advances in these devices for robotic surgery and on HIFU applications of ultrasound.

Participant interaction and questions will be encouraged.

This edition of Virtual Collaborations will be available to UIA members at $50 / students at $25 / nonmembers at $75.

Virtual Collaborations for 2021-2022

This year's virtual collaborations have been very well received and as a result we are turning them into a regular program of the UIA.

Look forward to invites for four separate sessions during the course of the year, in February, June, September and November.  We have selected this schedule so that we can bring you great content on a regular basis but not interfere with our annual conference or summer holidays!  And we will be adding a new wrinkle to these presentations, a mini-symposium!  The presentations in February, June and November will continue with our 1 hour format and a topic of discussion, but our September session will be an expanded 2 hour mini symposium with a series of presentations on a specific area of ultrasonic technology, ranging from ceramics, transducers, control systems waveguides and other technologies.  And don’t forget our main symposium in April!

We look forward to seeing you at these presentations during the course of the year!

The first Virtual Collaboration was held on Thursday, 24 September 2020 


One of my favorite aspects of Ultrasonic Industry Association symposiums is the collaboration that occurs during breaks in the actual symposium presentations.  Ultrasonic technology is highly non-linear and often confounding, and bouncing thoughts with peers is practically impossible on a day to day basis due to the significant intellectual investment necessary to understand the issues.  With the current pandemic, it is not feasible for many to meet in person and have these collaborations.  That is why I am looking forward to the UIA’s virtual collaboration on applying pre-load to Langevin-type piezoelectric transducers.  Over the years I have experienced several instances of pre-load issues that at the time were confusing, but with hindsight are completely understandable.  These collaborative discussions provide the insight needed to overcome common issues that are otherwise difficult to comprehend.
