"I have known (S4 cofounder) Emile Daoud for many years, and I respect his extensive clinical experience and contributions to the world of electrophysiology," Tanaka says. "I'm looking forward to being a part of the team that moves S4's technology into the market, making a valuable difference in AF ablation."

Dr. Emile Daoud, coinventor, cofounder, and chief medical officer, says Tanaka's leadership and knowledge in the field of electrophysiology brings a valuable perspective to the company. "Roy's impact on the world of electrophysiology is enormous. His leadership introduced great advances in the technologies we use on a daily basis. We are building S4 for the next phase of development," says Daoud, "and are grateful to add to our roster of talented directors who believe that this innovative technology will further our cause to bring safety and efficiency to ablation procedures."

In the last year alone, S4 achieved several exciting milestones towards bringing the esolution device to market, including a successful first in human study, an issued patent, and a new round of funding. "S4 is on a fast pace to success and we are excited to have Roy on the team. His knowledge, executive experience, industry contacts, and numerous successful product launches makes him the perfect addition to the S4 team," says cofounder and CEO William Fuller.

Bey scores 33, leads No. 16 Villanova past Georgetown 80-66

Jun 3, 2020

PHILADELPHIA — Saddiq Bey hit eight 3-pointers and scored a career-high 33 points to lead No. 16 Villanova to an 80-66 win over Georgetown on Saturday. Bey, a 6-foot-8 sophomore forward, hadn't been much of a 3-pointer shooter this season for the Wildcats (12-3, 3-1 Big East). He'd made only 21 and four of those came in a nonconference game against Ohio. He shot just 3-for-10 overall in a win this week at Creighton, hardly a sign he was about to bust out with a career game against the Hoyas (11-6, 1-3). Left open, and determined to shoot, Bey had...
