JP2000279525A - New catheter vibrator needle device removing atheroma in narrowed area by vibration and sucking it out, and its manufacture - Google Patents

Abstract

PROBLEM TO BE SOLVED: To appropriately ease a hematogenous disorder by inserting a vibrator needle with a suction port in a blood vessel of a narrowed area causing the arteriosclerosis, inflating a balloon in a part of atheroma, pushing it wide from the inside, softening the atheroma by the vibration, and sucking it out front the body. SOLUTION: Where a treatment of inserting a catheter in a narrowed area of the coronary artery, inflating a balloon, and pushing the coronary artery wide from the inside is performed, there is such a tendency that the arteriosclerosis part enlarged by applying the pressure is narrowed again with time. A new catheter (a vibrator needle with a suction part) 1 is used as a means for discharging the atheroma 3 from the body, the balloon 2 is inflated in a part of the atheroma 3 causing the arteriosclerosis so as to enlarge the narrowed part. Then, the new catheter 1 is inserted in the part of the atheroma 3, while injecting solubilizing agent therein, the new catheter 1 is vibrated by the vibrator to stir the atheroma, soften it, and then sucked it out from the body.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrialization) In the prior art, a catheter was inserted into a stenotic part of a coronary artery, and a balloon was inflated to expand the coronary artery from the inside. Severe people with angina and myocardial infarction attacks that have narrowed the atherosclerotic part that has been spread again are performing vascular bypass surgery, but use atheroma to solve the problem that burdens the patient Use recurrence means (new catheter) to prevent recurrence.

(Effect) It is possible to inhale the atheroma out of the body by injecting a dissolving agent into the atherosclerosis and vibrating it with a vibrator while stirring the atheroma softly.

(Effect of the Invention) The atheroma at the stenotic part causing arteriosclerosis is discharged out of the body to clean the inside of the blood vessel and improve the blood flow, thereby eliminating blood circulation disorders.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for vibrating an atheroma, shaking and softening the atheroma, and sucking the atheroma out of the body with a new catheter vibrator needle, and a method for producing the same.

[0002]

2. Description of the Related Art In a conventional technique, a catheter is inserted into a stenotic part of a coronary artery to inflate a balloon, thereby expanding the atheroma of the coronary artery from the inside.

[0003]

In a conventional catheter, a stenotic portion of a coronary artery is inflated with a balloon. However, there is an individual difference, and after a lapse of time, the stenotic portion which has been expanded by applying pressure narrows again, resulting in angina pectoris and myocardial infarction. There is a problem of repeated attacks.

According to the present invention, atheroma causing arteriosclerosis with a new catheter vibrator needle is vibrated with a vibrator needle while injecting a dissolving agent, and the atheroma is shaved, stirred and softened, and sucked out of the body with a new catheter vibrator needle to improve blood flow. The purpose is to do.

[0005]

In order to achieve the above object, a new catheter vibrator needle of the present invention is a device in which a vibrator is attached to a catheter.

An irregular portion is formed on the outer peripheral surface of the distal end portion of the new catheter, and atheroma is cut off at the irregular portion when vibrating.

[0007] A mechanism for providing a hole at the mouth of the new catheter to discharge atheroma causing arteriosclerosis outside the body.

[0008]

The atheroma at the stenotic part causing arteriosclerosis is discharged out of the body to clean blood vessels and improve blood flow, thereby eliminating blood circulation disorders.

Claims (3)

[Claims] 1. A stenotic part having a suction opening is inserted into a blood vessel of a stenotic part causing arteriosclerosis, a balloon is inflated at an atheroma part, the balloon is expanded from the inside, and pressure is applied to the stenotic part. A method for preventing atheroma 3 from diffusing into blood vessels by making the bag into a bag. 2. A mechanism in which a vibrator needle is inserted into the atheroma from the side of the balloon and is vibrated by the vibrator needle while injecting a dissolving agent to soften the atheroma, suck the atheroma from the suction port, and discharge the atheroma out of the body from the new catheter. How to clean and improve blood flow. 3. The method for producing a new catheter according to claim 1 or 2.
