The present invention provides a method of treating or alleviating erectile dysfunction in a patient. Multiple electrodes are placed within a segment of the internal iliac artery of the patient and against blood vessel wall of the internal iliac artery. Radiofrequency energy is released through at least one of the multiple electrodes to nearby tissues, so as to increase the temperature of the nearby tissues and induce a thermal alteration of the nearby tissues.

Method of treating or alleviating erectile dysfunction

The present invention provides a method for treating diabetes, a diabetes-associated condition or disorder, or symptoms thereof suffered by a subject such as a mammal (e.g. a human patient or a pet), comprising (1) placing multiple electrodes within at least one renal artery of the subject and against blood vessel wall of the at least one renal artery; (2) adhering a surface electrode on an external surface such as skin of the subject; and (3) releasing a therapeutically effective amount of radiofrequency energy through at least one of the multiple electrodes to nearby tissues, so as to increase the temperature of the nearby tissues and induce a thermal alteration of the nearby tissues.

Method for treating diabetes, diabetes-associated condition or disorder, or symptoms thereof

A corrugated radiofrequency ablation catheter and an apparatus thereof. The radiofrequency ablation catheter is provided with a strip-shaped connecting catheter (). An electrode frame is provided at the front extremity of the connecting catheter (). A control handle () is provided at the rear extremity of the connecting catheter (). The electrode frame is a corrugated electrode frame consisting of one or more corrugations. One or more electrodes () respectively are distributed on the corrugations. Slidable, supporting, wall-attaching adjustment wires () are provided within one lumen of the connecting catheter () and the electrode frame. The supporting, wall-attaching adjustment wires () are divided into a flexible segment () away from the control handle and a rigid segment () in proximity to the control handle.

Corrugated radiofrequency ablation catheter and apparatus thereof

The present invention provides a method of relieving or alleviating abdominal cancer pain or improving pain VAS score in a cancer patient Multiple electrodes are placed within a segment of the abdominal aorta of the patient and against blood vessel wall of the abdominal aorta. Radiofrequency energy is released through at least one of the multiple electrodes to nearby tissues, so as to increase the temperature of the nearby tissues and induce a thermal alteration of the nearby tissues.

Method of relieving or alleviating pain suffered by abdominal cancer patients

Disclosed are a radio-frequency ablation catheter having a spiral structure and device thereof. The radio-frequency ablation catheter has an elongated catheter body. A spiral electrode support is arranged at the front end of the catheter body. Multiple electrodes are arranged on the electrode support. A control handle is arranged at the rear end of the catheter body. Wall-attachment adjusting wires having various structures can be arranged in the radio-frequency ablation catheter, so that the radio-frequency ablation catheter having a spiral structure can be adapted to target vessels of different diameters, and so that the electrodes on the electrode support have a good wall-attachment state.

Radio-frequency ablation catheter having spiral structure and device thereof

Provided in the present invention is a three-dimensional precise intracavitary radiotherapy method and system for treating tumours, comprising the steps of: (1) lesion three-dimensional quantitative measurement and analysis of three-dimensional scanning image of the lesion cavity; (2) comprehensive analysis according to lesion three-dimensional quantitative measurement results and lesion characteristics to calculate the three-dimensional distribution of lesion radiation dose; and (3) according to the three-dimensional distribution diagram of radiation dose, selecting appropriate radiation sources and radiation dose to make a stent, and performing three-dimensional precise intracavitary radiotherapy. At the same time, also provided by the present invention is a system for achieving the above radiotherapy method. The present invention uses modern medical imaging three-dimensional reconstruction technology for realizing three-dimensional precise internal radiotherapy to treat tumours with an optimized radiation dose and protect normal tissues to an extreme.
