Dinker Belle Rai is a Board Certified Indian American vascular surgeon who serves as the Chairman of the Department of Surgery and as the Chief of the Department of Vascular Surgery / Vascular Laboratory at the Interfaith Medical Center, Brooklyn, New York. He is a visiting Clinical Professor at the Health & Science Center of the State University of New York in Brooklyn and a visiting Professor at the Rajiv Gandhi University in Bangalore, India. Rai is a Fellow of the American College of Surgeons and a Fellow of the Royal Canadian College of Surgeons. He is credited with developing the first ever method for retrograde catheterization of the venous tree. This invention was given a United States patent in 1988.[1] Based on this patent, a company called The Ideas For Medicine, Inc. (now part of Horizon Medical Products, Inc.) manufactured and still distributes out a series of catheters, known as Rai’s Catheters for use in performing descending phlebographic tests and for venous embolectomies.[2] He is also credited with the discovery of the motion of venous valves in human beings. His original research on histopathological specimens of patients with saphenofemoral – incompetency resulted in a paradigm shift in management of varicose veins. He performed the first ever vein transplantation below the knee. The discovery of right atrial mechanical function is a pivotal discovery in his medical research work. He is an editor for the International Journal of Angiology.[3] Rai has been featured in the book "Jewels of India"[4] for his contributions in the medicine, art, sports and cultural arenas.

  • Descending Phlebography.

Surgical techniques and inventions

Patent showing method to catheterize venous tree in retrograde fashion
  • Rai is a pioneer in chronic venous disease research. He implemented new techniques for descending phlebography to diagnose venous disease. He devised a surgical procedure for vein valve transplantation[9] and a surgical procedure for venous embolectomy. He also invented a diagnostic test for venous hemodynamics. He created a surgical technique for small vessel anastomosis in arterial surgery and vein patch arterioplasty. Earl U. Bell of the national news channel CBS interviewed him about vein valve transplant surgery and his invention, the Rai’s Catheter.
  • Invention of Catheters: Rai is credited with creating the following catheters

- The Rai’s catheter for percutaneous extremity approach
- The Rai’s three lumen balloon catheter – for groin approach
- The Rai’s “J” tip catheter – for groin approach
- The Rai’s antegrade venous embolectomy catheter
- The Rai’s retrograde venous embolectomy catheter

NOTE: Catheters a, b and c are used in the diagnosis of venous disease to perform descending phlebography.

  • He displayed his Venogram Catheter at the 5th European American meeting for venous disease, Vienna, 1990, American College of Surgeons, San Francisco, 1990, Society for Clinical Vascular Surgery, New York City, 1989 and the American College of Surgery, Atlanta, 1989.
  • Rai's videotapes on these surgical procedures is available in the American College of Surgeon Education Library: Infragenicular Arterial Reconstruction (15 minutes).[10] He also has videotapes on Vein Valve transplantation - A New Technique (15 minutes), Descending Phlebography – Pericarpal Subcutaneous Approach (15 minutes), Venous Embolectomy – A New Technique (15 minutes).

New discoveries

Rai discovered the motion of venous valves in human beings i.e. its rhythmical opening and closing during each cardiac beat. This new information on venous valves comes almost 500 years after discovery by Fabricus Acquapedente of Padua University that venous valves are one way doors allowing blood to go towards the heart.[11]

He discovered that venous blood flow is pulsatile which, prior to Rai's discovery, was described only as linear flow.

He is best known for his discovery of the mechanical function of atrial chambers of the heart. With experimental evidence on the canine heart, he discovered that atrial diastole is the key force that creates a negative pressure that brings blood back to the heart. Diastole is an - active expansion of the muscle on which the cardiac return depends. This is an addition to Starling’s law of muscle contraction that muscle not only actively contracts but expands as well. This significant historic discovery was made approximately 500 years after Sir William Harvey's discovery of the mechanical function of Ventricular Systole. This discovery has opened doors for new understanding / treatment of heart failure, atrial fibrillation and in improving the design and functioning of prosthetic hearts.

Sports career

Rai captained the Bangalore University cricket team that won the South Zone finals and that, for the first time, went all way to the All India finals in 1969. He captained the Combined Universities Cricket team of the South Zone of India and Sri Lanka in 1969. He was selected for the Karnataka Ranji Trophy team in 1970.[12] In lieu of his contribution to cricket, his name is on the Honor Roll at the Chinnaswamy Stadium Cricket Museum in Bangalore.

He is an avid golfer and his interest in the sport led him to promote a project to build a PGA standard 18 hole golf course through his company, Indus International Golf Resorts and Estates[13] in Bangalore, India. The project is currently in progress. The architects of the golf course are Ronald Fream and Kevin Ramsay of Golf Plan and the construction is being managed by an American construction company, Heritage Incorporation.
