Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, specifically a novel implantable left ventricular defibrillation electrode balloon. Background Technology

[0002] Left ventricular defibrillation refers to a treatment for ventricular fibrillation, which involves applying a high-energy electrical current to the heart to restore a normal heart rhythm. Defibrillation is an emergency treatment that requires rapid action. Once ventricular fibrillation occurs, left ventricular defibrillation should be performed immediately to restore a normal heart rhythm. Timely defibrillation can effectively avoid or reduce adverse consequences such as myocardial ischemia, myocardial infarction, and brain damage, thereby saving the patient's life.

[0003] The necessity of left ventricular defibrillation lies in the fact that ventricular fibrillation is a serious arrhythmia that prevents the heart from effectively pumping blood, leading to insufficient blood perfusion and endangering life. Ventricular fibrillation is an abnormal state of cardiac electrical activity, characterized by simultaneous discharge of cardiac muscle cells, resulting in the heart's inability to contract normally. Ventricular fibrillation is a serious arrhythmia that can lead to insufficient blood perfusion, causing hypoxia, brain damage, heart failure, and death. The incidence of ventricular fibrillation is higher in patients with heart disease or high-risk groups; therefore, left ventricular defibrillation can save lives in critical moments. Secondly, long-term patients with this condition and some critically ill patients require long-term monitoring and treatment of ventricular fibrillation during monitoring. Current defibrillation methods mainly include:

[0004] Electrical defibrillation: One of the most commonly used methods of cardiac defibrillation, it terminates ventricular fibrillation by applying a high-energy current to the heart. The advantages of electrical defibrillation are that it is fast and reliable, and can convert the heart rhythm to a normal rhythm within seconds. Its disadvantages are that it requires professional medical personnel and equipment support, and requires a high level of technical skill from the operator.

[0005] Chemical defibrillation: refers to controlling arrhythmias by administering medication. The advantages of chemical defibrillation are that it is simple to operate and does not require professional medical personnel or equipment support. The disadvantages are that it takes a long time to achieve the therapeutic effect and there are certain side effects and risks.

[0006] Biofeedback defibrillation: This method controls arrhythmias by providing biofeedback. The advantages of biofeedback defibrillation are that it does not require drugs or electricity and has no side effects or risks to the body. The disadvantage is that the effect is relatively slow and requires a long time to achieve the therapeutic effect.

[0007] Airway reflex defibrillation: This method controls arrhythmias by stimulating airway reflexes; however, it is less common in clinical practice and its advantages and disadvantages have not been fully evaluated.

[0008] In general, electrical defibrillation is currently the most commonly used method of cardiac defibrillation, and its advantages of speed and reliability are widely recognized. However, electrical defibrillation is usually performed externally and cannot be precisely controlled. To address this, the applicant has designed a novel implantable left ventricular defibrillation electrode balloon based on the advantages and needs of electrical defibrillation. By directly inserting it into the ventricular wall, the electrode pads adhere to the ventricular wall, allowing for precise control of the defibrillation current, resulting in higher safety and more precise pacing control. Utility Model Content

[0009] To address the aforementioned technical problems, this invention proposes a novel implantable left ventricular defibrillation electrode balloon. The balloon comprises a catheter, a balloon, an X-ray marking ring, a platinum-iridium alloy strip, an external connection port, a platinum-iridium alloy strip retraction button, and a balloon inflation port. During use, the balloon is inserted into the heart via the catheter, positioning it in the left ventricle. Inflation is then performed through the balloon inflation port, causing the defibrillation electrode pads on the platinum-iridium alloy strip to adhere to the heart wall. The platinum-iridium alloy strip retraction button is then locked, releasing the balloon. The defibrillation signal is then transmitted to the myocardium through the defibrillation electrode pads, causing the heart to contract at a normal rhythm. Intracardiac defibrillation offers higher safety and more precise pacing control.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] A novel implantable left ventricular defibrillation electrode balloon includes an external connection port, a catheter, a scale, a platinum-iridium alloy strip retrieval button, a balloon inflation port, a platinum-iridium alloy strip, a balloon, and an X-ray marking ring. The novel implantable left ventricular defibrillation electrode balloon is characterized by: a catheter with a scale on it; a balloon and an X-ray marking ring at the front end of the catheter; a platinum-iridium alloy strip on the outside of the balloon; an external connection port at the rear end of the catheter; a platinum-iridium alloy strip retrieval button and a balloon inflation port near the external connection port; and the platinum-iridium alloy strip connected to the platinum-iridium alloy strip retrieval button inside the catheter.

[0012] Furthermore, the novel implantable left ventricular defibrillation electrode balloon is equipped with a catheter, the catheter having dimensions of 900-1000mm in length and 2.3-2.7mm in diameter, and being made of high-density polyethylene.

[0013] The novel implantable left ventricular defibrillation electrode balloon is characterized in that: the novel implantable left ventricular defibrillation electrode balloon is provided with platinum-iridium alloy strips, and eight platinum-iridium alloy strips are provided, located on the outer side of the balloon and the inner side of the catheter.

[0014] Furthermore, the novel implantable left ventricular defibrillation electrode balloon is provided with a platinum-iridium alloy strip, and a defibrillation electrode pad is disposed on the outside of the platinum-iridium alloy strip at the position of the balloon.

[0015] Furthermore, the novel implantable left ventricular defibrillation electrode balloon is equipped with a balloon, the balloon having a maximum inflation volume of 120ml and a maximum diameter of 56mm.

[0016] The novel implantable left ventricular defibrillation electrode balloon is characterized in that: the novel implantable left ventricular defibrillation electrode balloon is provided with an X-ray marking ring, which is made of platinum-iridium alloy and is circular.

[0017] Furthermore, the steps for using the novel implantable left ventricular defibrillation electrode balloon are as follows:

[0018] Step 1: The patient lies quietly flat. The needle is inserted into the subclavian vein near the apex of the lung to prepare for catheter insertion.

[0019] Step 2: Insert the catheter into the human body through the needle hole, and position the balloon in the left ventricle using Doppler ultrasound or cardiac angiography.

[0020] Step 3: Inflate the balloon through the inflation port to make the outer wall of the balloon fit against the inner wall of the heart, and observe the scale on the catheter to avoid excessive displacement of the catheter during inflation.

[0021] Step 4: Lock the platinum-iridium alloy strip retrieval button to release the gas in the balloon. At this point, the defibrillation electrode pads are firmly attached to the wall of the left ventricle.

[0022] Step 5: The doctor performs defibrillation treatment on the patient based on the patient's condition;

[0023] Step 6: When the patient requires continuous defibrillation treatment, the balloon inflation port is locked to fix the part of the catheter outside the body to the patient's body to prevent displacement due to movement.

[0024] Step 7: Remove the new implantable left ventricular defibrillation electrode balloon, open the platinum-iridium alloy strip retrieval button, retract the platinum-iridium alloy strip into the catheter, remove the catheter, and disinfect the needle site.
