New Delhi: Bladder cancer is the most expensive cancer to treat over a patient`s lifetime.Reported statistics show its incidence in India is over 200,000 with ~15,000 new patients diagnosed every year. Worldwide, bladder cancer is the fourth most common cancer in men and eighth in the women, with transitional cell carcinoma (TCC) comprising up to 90% of all primary bladder tumors.TARIS Biomedical, a cutting-edge biotechnology company based in Boston, USA, has invented a technology that can control bladder diseases to a great extent. Patients can be treated through this new technology by keeping a tolerable delivery system in the bladder which continuously releases the medication for several days to weeks in patients.The TARIS` delivery system is as simple as it is revolutionary. It comprises of a small, flexible silicone tube filled with drug tablets, and fitted around a thin wire frame that gives the system a "shape memory".The system can be placed into the bladder by a routinely used, simple catheter in the office. The shape provided by the wire frame keeps the system in the bladder, and because it is soft and flexible, it is tolerable in most patients, which allows them to carry on their normal daily activities.When deployed in the bladder it is like a "flexible spaghetti in a small pretzel shape". The water diffuses from the urine into the system, dissolving the drug. By carefully controlling the osmotic pressure in the tube, TARIS technology modulates the release rates of the drugs through a laser-drilled orifice, from days to weeks, according to the desired application.
