Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients.

Dr Kanj is an exceptional physician.He communicates clearly and provided rationale/data that was understandable to our family. The surgery he performed for our son is life-changing. We have been trying to resolve a progressive problem with my son's heart for almost two years. We drove 13 hours to Cleveland and his issue was resolved in 5 days. We feel so amazed at the care we received from Dr Kanj, Dr Ruthmann and the entire clinic during our week in Ohio. Because of these caring health care providers, our son will be able to go on to get married and pursue his plans of becoming a physician . Dr Kanj demonstrates care, engagement and attention that makes you feel like your health care is his priority and he knows how to help. I can't even find the words to express what a great experience this was and how much gratitude is in my heart.
