(9) Disclosed are a system and method for providing transmyocardial laser revascularization (TMLR) therapy to a patient more safely and effectively. The inventors of the instant application, over the years, found that the therapy using the CO.sub.2 laser with the EKG alone is not adequate, as only one form of electrical activity (diastole) is measured and that did not always coincide with the laser beam. This presents a danger of arrhythmia. Also, existing systems present a risk of thermal damage to the heart. The disclosed system and method overcome the said drawbacks with the existing TMLR procedure and provides improvements in safety and outcomes in using transmyocardial laser revascularization (TMLR) procedure in patients.

(10) In certain implementations, the disclosed system includes a CO.sub.2 laser unit, an electrocardiogram (EKG) unit, a Vectorcardiography (VCG) unit, and a control unit. The control unit is operably coupled with the laser unit, EKG unit, and VCG unit. The disclosed system may further include an echocardiography unit and an infrared sensor unit, both operably coupled to the control unit.

(11) Disclosed is a TMLR procedure for treating patients in need thereof, such as patients suffering from coronary artery diseases. The method includes measuring the electrical activity of the heart using EKG and Vectogram. Second, in order to ensure that channels are created while the heart is full of blood to prevent thermal damage and maintain patency of channels. Also, echocardiography unit and infrared unit can also be incorporated within the system. Vectogram and echocardiogram can be used in the analysis. The control unit of the disclosed system can compute optimal timing, pulse duration, and wavelength using the input investigational data measured from the EKG unit, Vectorcardiography unit, echocardiography unit, and an infrared sensor unit. The control unit can operate the laser unit of the disclosed system to set and/or display different parameters safely and efficiently. The optimized parameter of the laser can be used in performing the TMLR procedure. Channels can be made using a cylinder shape or conical shape in smaller areas. The laser beam can be fired during diastole considering the various factors including optimal timing, pulse duration, and wavelength.

(12) Personnel can be trained for operating the disclosed system, wherein such people can be certified for operating the disclosed system.

(13) The use of an echocardiogram is advantageous because the blood will prevent the beam from reaching other parts of the heart, preventing unnecessary internal damage. Infrared spectrum analysis can synchronize the best parameters of the laser beam, such as angle, power, intensity, pulse time, and others.

(14) The disclosed system can also use AI technology to further improve safety in the disclosed TMLR procedure, according to an exemplary embodiment of the present invention. Artificial intelligence (AI) and machine learning methods can be used to optimize the laser parameters using patient related data and medical history of the patient.

(15) The inventors have over fifty years of experience in developing and then utilizing Trans Myocardial Laser Revascularization in appropriate patients. The data from various experimental procedures, training, and practice can be used as a training dataset for training the AI model. The artificial intelligence (AI) model can be trained to analyze pertinent patient data such as age, severity of angina, medications, level of physical activity, and other information. The AI can synchronize with the laser beam parameters (location, power density, duration) to guide the surgeon in safely delivering precise beams to enhance safety and prevent thermal damage. Recommended training includes certification by the Board of Laser Surgery and cooperation with those currently performing TMLR with the Advanced Laser.

(16) It should also be noted that the precision and timing of the Laser through the use of additional measurements of real-time cardiac activity and AI, can enhance the patency of the channels. In research, it was found that channels produced hormones that prevented clotting, and long years of patency were achieved.
