Lake Cumberland Urology Named InterStimâ„¢ Center of Excellence
April 30, 2025

Kenneth Ruby, MD, Alisha Tartar Wilson, PA-C, and Joseph L. Garland, PA-C, of Lake Cumberland Urology Associates have been named an InterStim™ Center of Excellence by Medtronic (NYSE: MDT). The distinction is awarded to caregivers who have demonstrated exemplary use of the InterStim™ system and a commitment to patient care for those suffering from symptoms associated with overactive bladder (OAB), fecal incontinence (FI) and non-obstructive urinary retention.
OAB affects nearly one in six U.S. adults and is more common than diabetes.1,2 While not life threatening, OAB is significantly life-altering, making effective long-term bladder control critical. Many sufferers are frustrated, embarrassed and limit their lives socially, professionally and personally.3-6
The InterStim™ technology system delivers relief by gently stimulating the patient’s sacral nerves through a small device implanted in the lower back.7 Since its introduction in 1997, it has been chosen by more than 400,000 patients worldwide.
“We’re honored to receive the Medtronic InterStim Center of Excellence designation,” said Dr. Eric Ruby. “We strive to educate our patients about overactive bladder and fecal incontinence and provide the highest quality of care to achieve the best outcomes for patients.”
Carolyn Sparks, Lake Cumberland Regional Hospital CEO, added, “This recognition underscores our commitment to innovative treatments and patient-centered care. Our team is dedicated to improving the quality of life for those affected by these conditions, and we are proud to lead the way in utilizing advanced technology for patient relief.”
