Peripheral Arterial Disease

Peripheral arterial disease makes the arteries narrow with gradually reduced blood flow where cholesterol is gathered, which is a state called arteriosclerosis caused by lifestyle related diseases such as hypertension, hyperlipidemia and diabetes.
Peripheral arteries refer to blood vessels other than those in the heart and brain, and this disease often occurs especially in the blood vessels of limbs and causes various symptoms due to insufficient blood flow.
Once atherosclerosis causes poor blood circulation, sufficient oxygen and nutrients do not get supplied to organs and muscles, which leads to range of symptoms from as mild as numbness to severe as necrosis.
There are various therapies to improve these symptoms such as exercise therapy, pharmacotherapy, endovascular treatment and surgical operation. Amongst these options, what we are involved with is endovascular medical devices that minimizes the incisional wound.

Arteriosclerosis Obliterans

Arteriosclerosis obliterans is a vascular disease, which causes a circulatory failure (ischemia) due to the progression of arteriosclerosis and the vascular stenosis. One of the typical symptoms is a pain during walking. The mild symptoms include coldness and numbness and the severe ones include ulcer and necrosis, which sometimes leads to the amputation of lower extremity.
While the mild symptoms can be improved with conservative treatments such as exercise regimen or pharmacotherapy, the severe ones may require revascularization or the amputation of lower extremity.
(The risk factors for this disease are hypertension, hyperlipidemia, diabetes, obesity, etc.)

Endovascular Treatment for Arteriosclerosis Obliterans

For Arteriosclerosis obliterans, exercise regimes or pharmacotherapy are primary treatments. When they do not ameliorate the symptoms, catheterizations with a balloon or stent (net-like metal cylinder) or a surgical treatment such as bypass procedure is performed.
While surgical treatments were popular in the past, endovascular treatments have been conducted more actively in recent years.
The history of endovascular treatment is surprisingly old and dates back to 1965 when it was reported that the first catheterization was carried out by a physician in the US, and it is now widely performed as a common treatment.
A narrowed part (stenosis) or clogged part (occlusion) of blood vessel is called a lesion and symptoms get improved by expanding the lesion (vasodilatation) with medical devices such as a balloon or a stent in order to return the blood flow back to the original state.

Our Approach to Arteriosclerosis Obliterans

Peripheral artery disease, where there were previously limited treatments available by products including balloons and stents, nowadays has many more options by dedicated medical devices enabling to cross the hardened lesion caused by arteriosclerosis, and other devices such as drug coated balloons or stents. The sector however we still develop further as new medical devices to shave rigid lesion will be introduced in the near future.

We deal in endovascular medical devices for Arteriosclerosis obliterans.
Although we currently only distribute medical devices manufactured in Japan, we are planning to deal in foreign-made medical devices in the future and hope to contribute to this sector by offering a variety of beneficial medical devices for patients.
