Abstract: The present invention provides a catheter apparatus with a carrier comprising right-handed wire helixes and left-handed wire helixes that are plainly or bi-axially woven into a tubular structure. A therapeutic assembly wraps around one of the wire helixes to stabilize an associated interstice of the tubular structure. The regular shape of the carrier may be quickly recovered after the carrier is seriously bent or distorted in an intravascular treatment.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a medical device with a balloon-stent assembly comprising a stent, a balloon within the stent, and an ablation member. The medical device can be useful for a combined procedure of balloon angioplasty, radiofrequency ablation, and stent placement. The invention exhibits numerous merits such as simpler and precise operation, and a single device for multiple applications.
