The invention relates to medical healthcare equipment, in particular to a wearable multi-field radiation whole-body hyperthermia device. Heat is introduced into a radiating target (i.e., a great vessel) by means of probe beams, and the energy of ultrasound, infrared, laser, microwave, radio frequency and electromagnetic probes at each frequency range is introduced into a vascular circulation system through the radiation probe network composed of probe beams distributed on an attachment in the form of optimum biological heat absorption, and then heat is transferred throughout the body through a hemoperfusion method, so that the vivo tissue is rapidly heated through conduction of biological heat in the tissue. The device has the characteristics of high thermal utilization ratio, high blood flow rate and high specific heat, and thermal convection is rapidly conducted between the radiant heat and the tissue to realize whole-body hyperthermia, therefore, the device not only can realize the purposes of uniformity of the machine body and rapid temperature rise, but also avoid the phenomenon of local overheating, simultaneously, has the accessibility of a wearable device and is a high-efficiency hyperthermia equipment without ache.

A body tissue treatment system comprising a heating device and a topical cream comprises controlled, non-burning heat exhibiting greater temperature fluctuation than a conventional heating device. At high temperature settings, the heating elements fluctuate widely between a relatively high maximum and low minimum to produce periods of intense heat input into the skin followed by sufficient cooling to prevent burning of the skin. Such application of intense heat to the skin, for short periods in which temperatures reach their peaks, relaxes musculature surrounding the injured area and significantly improves blood flow, skin permeability, and sweat gland openness in the area, which allows the topical cream to more readily penetrate skin and/or injured body tissues. While the skin temperature rises and falls to some extent in response to the heating device, the intense heating periods are believed to cause such high blood flow and consequent heat transfer away from the skin surface that the skin temperature does not rise to the extent of being damaged or burned.

The invention is a new generation permanent heart assist device developed to be installed into great arteries such as trans-aortic and trans-pulmonary artery to maintain blood circulation of the patients with end-stage heart failure. This device is a sort of brushless, synchronous, servo, electric motor which uses direct driver technology. It consumes little energy and provides high blood flow. The specially designed hollow rotor without a pivot pin provides enough blood flow to the patient by pushing the blood forward with the helical winglets inside it. The risk of thromboembolic events on the foreign surface that contacts with blood is less than in the counterparts of this device. Finally, the invention; is a curved permanent heart assist device that is applied on the aortas, reinforced twice with double stators and designed in smaller size so as not to compress surrounding tissues and organs.

Invention is related to; a new generation Heart Assist Device that is installed in the great arteries and developed for facilitating blood circulation for patients with heart failure. The device is composed of a rotor without an axial pin miming in magnetic bearing and because of its small size consumes less energy that causes to have longer battery lives. Because of its high power it generates high blood flow and because of having small contact surface does not cause to any harmful effects for blood cells and coagulation systems. Since installation of this assist device is quite practical and reliable its success rate will be quite high too.

The invention is a next generation miniature heart assist device developed in order to maintain the blood circulation in patients with severe heart failure, and is applied endovascularly to the large arteries. This device is technically a kind of synchronous servo electric motor using “direct drive technology”. It provides longer battery life and high blood flow. Small volume and very low energy consumption provide a much longer battery life and a high blood flow. As the outer surface of the parts placed into the blood vessel will be completely covered with the endothelial cells and the intima layer of the arteries in time, there will be no foreign surface contacting directly with blood. As a result, no thromboembolic event or any negative effect on the cellular components of blood is expected.

The invention discloses a stent selection method based on three-dimensional reconstruction of a coronary artery, which comprises the following steps: S1, acquiring hemodynamics parameters in coronaryartery CT contrast data and diameters of coronary artery in coronal plane, sagittal plane and cross section in thin-section CT image; S2, performing three-dimensional reconstruction according to the acquired data to obtain a 3D model of the coronary artery; S3, obtaining the initial blood flow reserve fraction in the coronary artery 3D model according to the hemodynamics parameters in the coronaryCT contrast data; S4, singly implanting different virtual stents in the 3D model of the coronary artery to obtain 3D models with implantation of different virtual stents; S5, adjusting the implantation position of each virtual stent to obtain the blood flow reserve fraction corresponding to different positions of each stent; S6, selecting the virtual stent and implantation position correspondingto the highest blood flow reserve friction to complete the stent selection. According to the invention, the method overcomes the disadvantage that the clinical stent selection can only rely on experience.

The invention can selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This is done by exposing the lung to an electromagnetic field causing dielectric or eddy current heating. The invention is particularly useful for treating emphysema as the diseased areas have reduced blood flow. The diseased area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow. To avoid heating of surrounding organs the direction of the electromagnetic energy is switched in a way it always passes through lungs but only intermittently passes through adjacent organs. If heat activated drugs are present in the lungs, they are selectively released in the heated tissue.
