Intellectual medical system "Perfocor" for transmyocardial laser revascularization
Over recent years, a totally new method of curing the ischemic disease of heart, transmyocardial laser revascularization (TMLR), is gaining ground in the clinical practice. In the course of an operation, a laser pulse is employed to produce channels opening into the heart cavity. __________________.
| A laser beam is perforating the cardiac wall. It produces 20 to 50 holes of 0.5 to 1 mm in diameter. |
As compared to coronary artery bypass grafting, the TMLR method is easier in realization and much lower in cost. _____________________. The TMLR method is most effective in the cases when all the other techniques fail.
| __________. The system comprises a specially developed high-power waveguide СО2-laser operating in the pulsed mode, a mechano-optical manipulator for laser radiation delivery and focusing at an object, and an information system for ECG and revascularization process diagnostics. |
The "Perfocor" system surpasses in its technical performances (energy efficiency, perforated channel shape, weight, and compactness) the only analog system "Heart Laser" of the PLC Medical System, USA. ____________. (The "Perfocor" system was awarded the First Class Diploma and a gold medal at the International Trade Exhibition "INNOVATIONS-98" in Moscow, and a gold medal at the "III International Moscow Salon of Innovations and Investments" in 2003.)
The system has been patented in Russia (6 patents). In 2000, a "Perfocor"-type system was produced for the Czech Republic, where since then it has successfully passed clinical tests. _____________. In 2001, the system was approved by the RF Ministry of Health for serial production and clinical application. Since early 2004, the "Perfocor" system has been successfully used in a series of surgical operations at the M.F. Vladimirsky Research Clinical Institute (MONIKI).
A. The system was highly appreciated by the leading cardio-surgeons of Europe.
B. They favor the restoration of blood stream in the ischemic zone and prevent development of myocardial infarction.
C. In the period from 1997 to 2006, this system has been successfully employed in more than 500 successful operations at the A.N. Bakoulev Research Cardio-Vascular Surgery Center.
D. The operation is performed on the beating heart, and it is low-invasive.
E. The intellectual laser medical system "Perfocor" has been developed at ILIT RAS to perform TMLR operations.
