Description

막힌 혈관을 용이하게 통과하기 위한 지지풍선이 부착된 카테터, 및 그 이용방법Catheter with a support balloon to easily pass through the blocked blood vessel, and a method of using the same
본 발명은 혈관 내 시술을 위한 카테터 및 그 이용방법에 관한 것으로서, 보다 구체적으로는 막힌 혈관을 용이하게 통과하기 위한 지지풍선이 부착된 카테터 및 그 이용방법에 관한 것이다.The present invention relates to a catheter for endovascular treatment and a method of using the same, and more particularly, to a catheter with a support balloon for easily passing through a blocked blood vessel and a method of using the same.
의료기술은, 외과적 치료에서 환자에게 침습도가 낮은 방향으로 빠르게 발전하고 있다. 그 중에서 혈관 내 치료(Endovascular treatment)는 최근 시술의 범위가 급격하게 확대되고 있다. 이에 따라, 경험의 축적으로 인해 장비 및 기구의 발전이 이루어지고 있다.Medical technology is rapidly developing in the direction of low invasiveness to patients in surgical treatment. Among them, endovascular treatment has recently been rapidly expanding in scope. As a result, the development of equipment and appliances is underway due to the accumulation of experience.
혈관 내 치료에는 여러 가지 기구가 사용되는데, 그 중 하나가 목표하는 혈관을 찾아 들어가는 카테터(Catheter)이다. 의료 현장에서는 혈관 주사용, 관상동맥 확장용, 요도 삽입용, 복강경 수술용 카테터 등 다양한 신체부위에의 삽입을 위한 카테터들이 사용되고 있다.Several instruments are used for endovascular treatment, one of which is a catheter that finds and enters the target vessel. In the medical field, catheters are used for insertion into various body parts such as vascular injection, coronary artery dilation, urethral insertion, and laparoscopic catheter.
카테터(catheter)는 관 모양 기구의 일반적 명칭의 하나로서, 체강 또는 내강이 있는 장기 내로 삽입하기 위한 튜브형의 장치를 의미한다. 카테터는 체강이나 각종 기관 내의 저류물의 배출, 세정용 관류액의 흡인, 심혈행동태나 중심정맥압 등의 측정, 약물이나 조영제의 체내 주입 등의 용도로 이용되고 있으며, 이러한 용도에 따라 다양한 재질, 크기, 형태로 구성될 수가 있다.Catheter is one of the common names of tubular instruments and means a tubular device for insertion into an organ with body cavity or lumen. The catheter is used for the discharge of debris in the body cavity or various organs, the aspiration of the cleaning perfusion solution, the measurement of cardiovascular behavior or central venous pressure, the infusion of drugs or contrast agents, etc. It can be configured in the form.
그 중 관상동맥 확장을 위한 풍선 카테터는 예를 들면, 혈관 내로 삽입되는 안내관 선단 부근에 팽창용 풍선이 형성되어 있고, 이 풍선에 연동되어 있는 도관을 통해 유체가 도입되어 풍선을 팽창시키게 되며, 카테터의 혈관 내 삽입을 용이하게 하고 시술을 수행하는 역할을 하는 가이드 와이어가 상기 도관에 내장된 구조를 갖추고 있다.Among them, a balloon catheter for coronary artery dilatation includes, for example, an inflatable balloon formed near a tip of a guide tube inserted into a blood vessel, and fluid is introduced through the conduit linked to the balloon to expand the balloon. Guide wires that facilitate the insertion of the catheter into the blood vessel and perform the procedure have a structure embedded in the catheter.
그런데, 카테터는 혈관, 요도, 기도 등을 통해 정밀하게 삽입되어야 하고 그 조정이 미세하게 이루어져야 하기 때문에 정밀하게 제작되어야 할 뿐만 아니라, 의사의 수술편의성, 정확성 및 안정성의 관점에서 많은 개선이 필요하다. 또한, 뇌혈관, 관상동맥의 폐색으로 인한 뇌졸중, 급성 심근경색, 심장마비와 같은 심혈관계 치료분야에서 다양한 카테터의 개발과 이를 이용한 혈관성형 시술법이 개발되고 있다.However, the catheter is not only to be precisely manufactured because the catheter should be inserted precisely through blood vessels, urethra, airway, etc. and its adjustment is made fine, but also requires many improvements in view of the convenience, accuracy and stability of the surgeon's surgery. In addition, in the field of cardiovascular treatment, such as stroke, acute myocardial infarction, and heart attack due to occlusion of cerebrovascular and coronary arteries, various catheters have been developed and angioplasty methods have been developed.
대동맥에서 분지하는 정상의 총장골동맥은 여러 가지 카테터를 이용하여 용이하게 선택(Selection)할 수 있으나, 총장골동맥이 그 입구까지 딱딱하게 막혀있는 경우는 현재까지 제품화된 카테터를 이용해서는 총장골동맥을 선택하고 와이어를 진입하는 것은 쉽지 않은 경우가 많다. 폐쇄된 병변을 와이어가 통과하기 위해서는 단단한 지지가 필요하나, 카테터의 특성이 그렇게 단단하게 지지할 수 있도록 만들어져 있지 않기 때문에 와이어는 막힌 혈관을 통과하지 못하고 뒤로 튕겨져 나오게 된다.Normal iliac arteries branching from the aorta can be easily selected using various catheters.However, if the iliac artery is hardly blocked to its inlet, the total iliac artery has been manufactured to date. Selecting and entering the wire is often not easy. The wire needs rigid support to pass through a closed lesion, but because the catheter's properties are not designed to support it so tightly, the wire will not be able to pass through the clogged blood vessel and will bounce back.
도 1은 총장골동맥이 폐쇄된 혈관의 조영술 사진을 도시한 도면이고, 도 2는 총장골동맥이 폐쇄된 혈관의 CT 사진을 도시한 도면이다. 도 1 및 도 2에 도시된 바와 같이 총장골동맥이 그 입구까지 폐색이 이루어진 경우에는 기존의 카테터 제품을 통하여 병변부위를 통과하는 것이 쉽지 않다.1 is a view showing an angiography picture of the vessel in which the iliac artery is closed, and FIG. 2 is a view showing a CT image of the vessel in which the iliac artery is closed. 1 and 2, when the iliac artery is occluded to its inlet, it is not easy to pass the lesion through the existing catheter product.
병변의 아래쪽에서 와이어와 카테터를 삽입해 볼 수도 있으나, 이 경우에는 혈액의 흐름과 반대방향으로 시술이 진행되어야 하는바 어려움이 있고, 와이어가 병변을 지나 혈관 내로 재진입하지 못하고 내막하(Subintima)층으로 계속 진행되어 의인성(Iatrogenic) 대동맥 박리를 만들게 될 수 있다.Wire and catheter may be inserted at the bottom of the lesion, but in this case, the procedure must be performed in the opposite direction to the flow of blood, and the wire cannot enter the vessel through the lesion and the subintima layer May continue to produce an atrogenic aortic dissection.
물론 다른 재진입 기구 등을 사용하여 관통율을 향상시킬 수 있으나, 대동맥이라는 해부학적 위치의 특성상, 잘못 관통할 경우 복강 내 대량출혈 등의 합병증이 있을 수 있기 때문에 위험부담이 있다.Of course, it is possible to improve the penetration rate using other reentry mechanisms, but due to the nature of the anatomical location of the aorta, there is a risk because there may be complications such as massive intraperitoneal bleeding if penetrated incorrectly.
