In the past decades a variety of implants like artificial bone; heart valve; cardiac pacemaker and the tooth have been developed and come into use. These implants made of polymers, metals and ceramics. The implant material selection and design is aimed at restoration of lost function without producing adverse tissue and biochemical reactions. Innovations have brought in “bioactive” and “smart” implants. Some implants have the inbuilt design property of sensing the body status and in a biofeedback manner altering its properties to optimally respond under varying biological state of the individual. A laboratory has originated a very high molecular weight polyelectrolyte polymer implant which in vivo generates electrical charge and modifies the electrical surface charge of the millions of sperms formed in the male system every day to achieve contraception which may be reversed. An advancement of this implant named RISUG contains besides the polymer magnetic iron and electrically conducting copper to give “smart” physiology responsive and infection resistance giving properties. A still further innovation of the implant named RISUG adv within the body sets up virtually a nano liposome manufacturing centre. The raw materials for the manufacturing are partly drawn from biochemicals and tissue fragments naturally existing inside the body and partly from the artificial implant placed within the body. The manufactured entities known as “Invivgensome” give potential for prevention of Prostate Cancer, the main male cancer of current times. This implant innovation from India opens the doors to diverse in vivo “manufacturing” which will help in disease prevention, therapy as well as rehabilitation.

Profile Of Speaker

Sujoy Kumar Guha is an Indian biomedical engineer. He was born in Patna, India, in 1939. He did his graduation (B.Tech.) in electrical engineering from IIT Kharagpur. He received his Ph.D. in Medical Physiology from St. Louis, United States. He then founded the Centre for Biomedical Engineering, IIT Delhi and AIIMS and also obtained his MBBS degree from Delhi University.

One of the founders of Biomedical engineering in India, Prof. Guha is internationally renowned in the areas of Rehabilitation Engineering, Bioengineering in Reproductive Medicine and Technology for Rural Health Care. He has received several awards and has more than 100 research papers in cited journals.

His major contributions have been in the indigenously developed non-hormonal polymer based injectable male contraceptive (RISUG) for which the Final Phase-III Clinical trials are underway; Problem-solving at a national level regarding contraceptives in mass usage, especially Copper T; individualized spot air-conditioning system for hospital patients and rehabilitation of the blind, with emphasis on opening automobile repair as an employment avenue.

He has led scientific research which brings about a synthesis of engineering and biomedical sciences and the setting up of academic programs at the national and international levels. His work has given a foundation for Biomedical Engineering in India.

He has introduced to the international scientific community the area of Bioengineering in Reproductive Medicine and authored the CRC book publication “Bioengineering in Reproductive Medicine”. Professor Guha's technological work has helped develop in India a strong manufacturing base of contraceptives including the Copper T and the Fallopian Tube Occlusion Ring. At present Prof. Guha is developing a clinical Andrology program and is also the president of the society of Andrology, India.
