Honoring the extraordinary life of a medical device inventor

Biosense Webster co-founder Wilton Wells “Will” Webster, Jr. passed away peacefully at his home on November 10, 2018 at the age of 90, leaving behind a far-reaching legacy of innovative medical devices he invented for cardiac doctors.

“Will was a true gentleman, dedicated family man and a pioneer. He had the pleasure of seeing his inventions make a huge difference for so many lives.” – Shlomi Nachman, Company Group Chairman, Johnson & Johnson Medical Devices

Engineering Opportunities in a War-Driven Economy

Will was born on January 29, 1928 in Pasadena, California. At a young age he witnessed not only the economic crisis of the Great Depression but also the recovery that came with WWII as all manner of sleek new war machines had to be produced. Seeing the new planes and aircraft carriers equipped with radar inspired the young Webster to study engineering at the California Institute of Technology, received his BS in Mechanical Engineering in 1949.

Will found employment with C. F. Braun & Company, an engineering construction firm that built oil refineries and chemical plants. He designed heat exchangers and worked with the welding experts to overhaul the company’s welding standards. Later he moved into the Project Purchasing Department where he learned about plant design, along with precision ordering of parts and equipment to arrive when needed. After eight years, Will was let go. He was too much of an independent thinker and nonconformist for the straight-laced company – qualities that would serve him well in his future endeavors.

The Shift to Medical Technologies

Will spent the next 10 years as a sales representative for a small electronic components manufacturer supplying parts to companies involved in the aerospace industry. It was a phone call from a UCLA medical student that sent Will in a whole new direction. The student was experimenting with the use of thermistors, tiny temperature-sensitive resistors, in sensing blood flow. Will set up his own small laboratory in a rented building to experiment with the technology. When Dr. William Ganz, a prominent cardiologist called him about adding sensors to heart catheters, Will was ready. He soon found himself making prototypes of a device that came to be known as the Swan-Ganz thermodilution catheter. Their combination of heart knowledge and engineering knowledge was unique at the time, and proved to be invaluable.

“Wilton Webster was a force for so much that is good in this life. His work has resulted in ending the suffering of millions. His generosity, personally, and through his foundation, enhanced the appreciation of the Arts and fostered the advancement of scientific knowledge that has and will change the world. What a legacy. What a role model to live up to for all of us.” – Dr. Benjamin J. Scherlag, PhD, University of Oklahoma

Will resigned from the sales job and officially formed Wilton Webster Laboratories in 1969. He was suddenly an entrepreneur. Working with Ganz, they invented the Coronary Sinus Blood Flow Catheter. Cardiologists from all over the world came to learn from Ganz, and if they wanted to pursue his techniques in their own hospitals, the only place they could purchase the catheter was from Webster Laboratories. Will also had the foresight to file patents on his medical inventions.

Another fruitful early collaboration was with Dr. John Kirklin, one of the first open-heart surgeons. He needed a specialized instrument to monitor muscle quiescence and temperature during extended surgeries, and Webster Laboratories designed and built the needed device. Will observed his device in action during an open-heart surgery on a one-year-old boy – an experience he would never forget and which inspired him in his work.

Electrophysiology: Studying Heart Rhythm Abnormalities

The up-and-coming field of electrophysiology (EP) and electrode heart catheters became Will’s next opportunity for medical device innovation. There was only one competing company, but it did not offer custom builds, which had become Will’s specialty. When a phone call came from Dr. Sonny Jackman at the University of Oklahoma requesting a special orthogonal electrode catheter, Will had it designed and built within two days. Based on these successes and rapid growth, the company was incorporated as Webster Laboratories, Inc.

“Will was a brilliant engineer and inventor. He created the tools critical for the development of RF ablation. Perhaps most important, Will was humble, kind, generous, thoughtful, and endeavored always to do the right thing. ” ~ Dr. Warren M. (Sonny) Jackman, MD, University of Oklahoma

The gap Will and Sonny saw was that heart arrhythmias were not being effectively treated with the catheters that were available at the time. They worked together on potential solutions utilizing radio frequency energy to correct arrhythmias. More specifically, their work resulted in a cure for the congenital heart defect called WPW or Wolf–Parkinson–White Syndrome. Electrophysiologists from around the world came to Jackman’s lab to learn about his techniques, and they all ordered Will’s steerable tip catheters for their own labs.

The radio frequency (RF) ablation therapy and devices pioneered by Will and Sonny quickly became standard practice throughout the 1990s. Will continued to make improvements in RF ablation for more than a decade by introducing irrigation, creating an 8mm tip with dual sensors, and developing the first ablation catheter with an embedded electro-magnetic sensor. He also contributed his inventiveness to developments in diagnostic catheters, including close-spaced electrode catheters, basket catheters, the HALO catheter and the Crista Cath 20-pole deflectable catheter.

“It was just amazing how he was able to create the catheters that we envisioned.” ~ Dr. Mario D. Gonzalez, MD, Penn State Heart and Vascular Institute

Many of the innovations Will created were the result of specific requests from cardiologists. When a doctor contacted him with an idea, he was always ready and able to quickly move the idea through the design and prototyping of a solution.

“I don’t remember him ever failing us.” ~ Dr. Gerald V. Naccarelli, MD, Penn State Heart and Vascular Institute

At his alma mater, Caltech, Will served as a member of the Chair’s Council for the Division of Chemistry and Chemical Engineering (CCE), helping shape the division’s future direction. Through the Helen and Will Webster Foundation, he contributed funds for the construction of the Warren and Katharine Schlinger Laboratory for Chemistry and Chemical Engineering, supported graduate fellowships for CCE students, provided discretionary resources for new initiatives within CCE, and established an undergraduate scholarship named in memory of their son, William Wilcox Webster.

He and his family foundation also gave generously to the University of California Santa Cruz, where his son Alec worked for 14 years as a precision machinist and technician for the Santa Cruz Institute for Particle Physics before deciding to pursue an environmental studies degree from UC Santa Cruz. Chancellor George Blumenthal sums it up this way: “Will Webster created a flourishing business improving the lives of cardiac patients. Then he continued changing the world through the good works of the Helen and Will Webster Foundation.”

Their generosity to UC Santa Cruz included the establishment of five different presidential chairs, renovation of the Cowell Ranch Hay Barn, the naming and endowment of Rachel Carson College, and support for other initiatives across campus such as environmental programs, the Center for Agroecology and Sustainable Food Systems, the Libraries, and the Quarry Amphitheater.

One of the more recent chairs established was the Wilton W. Webster Jr. Natural Reserves Presidential Chair, reflecting Will’s dedication to environmental protection and conservation that developed in his later years. The UC Santa Cruz Natural Reserves is a network of 39 protected sites throughout California covering more than 756,000 acres. They serve as a living laboratory supporting university-level teaching, research, and public service for wise management of the Earth and its natural systems. To get a detailed picture of the profound impact the Webster family has had on UC Santa Cruz and Rachel Carson College, see Philanthropy in Pursuit of a Healthier Planet, showcasing the results of their generous giving.
