Targeted dilatation forming balloon catheter

Abstract

The invention relates to the minimally invasive therapy technology and a minimally invasive therapy instrument, in particular to a method and instrument for forming a targeted balloon of a living body catheter cavity, namely a minimally invasive surgery method and instrument for carrying out targeted rear urethra balloon dilatation forming on the rear narrowed urethra of the male, wherein the rear narrowed urethra might be caused by the BPH, a tumor, an inflammation and the like. The targeted dilatation balloon dilatation catheter is provided with at least one targeted dilatation balloon, wherein one cavity is used for draining or conveying body liquid or gases and another cavity is used for filling a targeted catheter cavity dilatation balloon. At least a row of protrusions for targeted dilatation forming or a protrusion for targeted dilatation forming is arranged on the surface of the targeted dilatation balloon in the direction of the long axis. The protrusions or the protrusion for targeted dilatation forming aligns with a zone or a part, needing targeted dilatation forming, of the catheter cavity and expands in a certain manner, at a certain speed and under the certain pressure to form the balloon. Thus, the targeted dilatation forming protrusion or protrusions form selective partial high intensity of pressure and high shearing force on the targeted forming zone of the catheter cavity and targeted dilatation forming of the catheter cavity is achieved.

Description

technical field [0001] The present invention relates to a minimally invasive treatment technology and device, more specifically to a targeted balloon forming method and device for the lumen of a living body, and especially to a method for treating men with benign prostatic hyperplasia, tumor, inflammation, etc. Minimally invasive surgical method and instrument for targeted posterior urethral balloon dilatation of posterior urethral stricture. Background technique [0002] Benign prostatic hyperplasia is a common disease in elderly men, often accompanied by lower urinary tract symptoms, which seriously affects the quality of life. As China enters an aging society, there are nearly 100 million patients suffering from benign prostatic hyperplasia. Most patients with less severe symptoms use drug therapy to delay the process of benign prostatic hyperplasia, but they need to take drugs for life, and the cost is huge. [0003] In the early surgical treatment, metal bougies of di...

AI Technical Summary

Problems solved by technology

[0007] The problems to be solved by the present invention are: the design of the existing balloon catheter dilatation catheter for the treatment of dysuria caused by benign prostatic hyperplasia is complicated, the selective targeted dilation and forming for clinical needs cannot be performed, and the balloon positioning technology in the process of dilation and forming is not reliable. It provides an efficient, safe, precise and targeted treatment of various luminal stenosis, especially a minimally invasive interventional treatment method and device for dysuria caused by benign prostatic hyperplasia, inflammation, tumors, etc.
