Minimally invasive surgery. Future developments.

The rapid development of minimally invasive surgery means that there will be fundamental changes in interventional treatment. Technological advances will allow new minimally invasive procedures to be developed. Application of robotics will allow some procedures to be done automatically, and coupling of slave robotic instruments with virtual reality images will allow surgeons to perform operations by remote control. Miniature motors and instruments designed by microengineering could be introduced into body cavities to perform operations that are currently impossible. New materials will allow changes in instrument construction, such as use of memory metals to make heat activated scissors or forceps. With the reduced trauma associated with minimally invasive surgery, fewer operations will require long hospital stays. Traditional surgical wards will become largely redundant, and hospitals will need to cope with increased through-put of patients. Operating theatres will have to be equipped with complex high technology equipment, and hospital staff will need to be trained to manage it. Conventional nursing care will be carried out more in the community. Many traditional specialties will be merged, and surgical training will need fundamental revision to ensure that surgeons are competent to carry out the new procedures.     

Long-lasting improvement of myocardial perfusion and chronic refractory angina after autologous intramyocardial PBSC transplantation

We report the case of a 60-year-old man with patent coronary by-pass grafts on the left anterior descending and circumflex coronary arteries, who experienced recurrent Canadian class IV angina refractory to medical and interventional treatments for a dominant right coronary artery occlusion. He underwent autologous PBSC transplant into the inferior ventricular wall through a minimally invasive approach as a stand-alone therapy, in an attempt to induce therapeutic angiogenesis. Six months after the operation, angina significantly ameliorated; scintigraphy and coronary angiography showed a marked improvement in perfusion of the target injection area. These benefits had persisted at 25 months after stem cell transplant.

A Biomimetic Spermatozoa Propulsion Method for Interventional Micro Robot

Nowadays, studies of the interventional micro robots have been hot topics in the field of medical device. The ultimate goal of medical micro robots is to reach currently inaccessible areas of the human body and carry out a host of complex operations such as minimally invasive surgery (MIS), highly localized drug delivery and opening up the blood vessels. Miniature, safe and energy efficient propulsion systems hold the key to mature this technology. In this paper, a prototype of endovascular micro robot based on the motion principle of spermatozoa is presented. The properties of this propulsive mechanism are estimated by modeling the dynamics of the swimming methods. In order to validate the theoretical results for spermatozoa propulsion, a scaled-up prototype of the swimming robot is fabricated and characterized in imitative bio-pipes full of silicone oil. Experimental results shown that the spermatozoa-like micro robot can be controlled to swim efficiently. And to adjust the rotation direction of the four flexible tails, the propulsion forces and the function of opening up the blood vessels will be generated.

Présentation des différentes avancées techniques en imagerie interventionnelle par résonance magnétique

The field of MR imaging has progressively grown from morphological imaging to physiological imaging and finally to interventional imaging. In fact, MRI is an imaging modality well adapted to the interventional practice, it is not only due to its high contrast to soft tissues and to the absence of ionizing radiations but also extensively benefited, as all minimally invasive therapies, of the progress of informatics, of electronics and of robotics. This review discusses the different innovations made in recent years. Different aspects are discussed, systems designs, devices tracking, pulse sequences, applications, each of them is followed by recent references in order to go into details.     

Galvanic apparent internal impedance: An intrinsic tissue property

Using basic galvanic cell principles, the ability of tissues to generate electrical current through electrolysis was characterized. Studying Zn/Cu electrolysis in animal organs revealed a fundamental and measurable tissue-specific property - the galvanic apparent internal impedance (GAII), that is most likely related to the salt bridge function of tissues delineated by electrodes. Further to the fundamental knowledge acquired, GAII enables a new diagnostic method to distinguish between tissue types and to determine their health status without a need for expensive calibration, as often required when external power source is used. We demonstrated the GAII sensitivity in detecting tissue ablation with microwave heating or irreversible electroporation. The results open the way for a novel, inexpensive self-powered tissue diagnostic system for a wide range of applications such as minimally invasive tissue health status, ischemia, hydration, real time intra-operative control of minimally invasive surgery, medical imaging, virtual biopsy and many others.     

Erythrocyte antioxidant defenses as a potential biomarker of liver mitochondrial status in different oxidative conditions

The need for minimally invasive biomarkers to predict the progression of non-alcoholic fatty liver disease to non-alcoholic steatohepatitis is a priority. Oxidative stress and mitochondrial dysfunction contribute in this physiopathological process. The aim of this study was to analyze the potential role of erythrocytes as surrogate biomarkers of hepatic mitochondrial oxidative status in an animal model under different dietary oxidative conditions. Interestingly, we found that erythrocyte antioxidant status correlated with triglyceride content (p?相似文献
