Business overview

Coronary artery disease is a condition where atherosclerosis causes the narrowing or blockage of the heart's blood vessels (coronary arteries), which reduces blood flow to the heart muscle. This can lead to angina or myocardial infarction, and if left untreated, it increases the risk of heart failure and sudden death. Coronary artery intervention uses balloon catheters or stent catheters to restore blood flow, with the aim of improving symptoms and preventing complications.

Peripheral arterial disease is a condition primarily affecting the arteries of the lower limbs, where atherosclerosis causes narrowing or blockage, leading to impaired blood flow. As the condition progresses, it can cause pain during walking, worsening leg wounds, and even blackening and necrosis of the toes. In the worst cases, this can lead to lower limb amputation. Lower limb intervention primarily aims to improve blood flow and enhance the patient’s quality of life by using a balloon catheter or a stent catheter to dilate blood vessels.

A cerebral aneurysm is a bulge that forms in a brain artery, and if it ruptures, it causes a subarachnoid hemorrhage*1. Treatment options include a surgical procedure that prevents further bleeding from the aneurysm by opening the skull and clipping the ruptured aneurysm with a metal clip, or an endovascular procedure using a catheter to fill the ruptured aneurysm from inside the blood vessel with “embolization coils.” In addition, advances in imaging technology have led to an increase in cases where unruptured aneurysms are detected before they can cause a subarachnoid hemorrhage. To prevent the rupture of these unruptured aneurysms, the use of endovascular treatment with “embolization coils” is also increasing.

• *1. A general term for a condition where bleeding occurs inside the arachnoid membrane surrounding the brain due to the rupture of a cerebral aneurysm.

Acute cerebral infarction is a condition where blood flow to a part of the brain is interrupted due to the blockage or narrowing of a cerebral blood vessel, leading to necrosis of brain tissue. This causes sudden neurological symptoms and may result in severe sequelae. As a treatment method, drug therapy to dissolve the blood clot during the acute phase is first administered. However, if the occluding clot cannot be removed, a thrombectomy may be performed to rapidly remove the clot mechanically using catheters such as a “cerebral thrombus aspiration catheter” or a “stent retriever.”

It selectively removes LDL cholesterol from the blood.

It is used to treat dialysis-related amyloidosis, which is one of the complications experienced by dialysis patients.
It is used to treat refractory ulcers in patients with severe arteriosclerosis obliterans. It adsorbs LDL and fibrinogen and improves blood flow.

Also, we have a non-invasive skin perfusion pressure measuring system for examining peripheral blood circulation in the limbs.

Gastrointestinal diseases refer to illnesses affecting the digestive (gastrointestinal) system.
The digestive organs form a continuous tract from the mouth to the anus. They break down ingested food into nutrients (digestion), absorb these nutrients into the bloodstream, and expel indigestible parts from the body. Gastrointestinal diseases affect our bodies in various ways, ranging from temporary symptoms, such as gastroenteritis and reflux esophagitis, to chronic gastritis and ulcers, and further progressed life-threatening conditions such as gastric cancer and colorectal cancer.

Biliary and pancreatic diseases are a general term for conditions related to the bile ducts, gallbladder, and pancreas. They are one of the diseases commonly seen in Japanese people. Gallstones can cause cholangitis or pancreatitis, and stenosis can obstruct bile flow by constricting the bile ducts. Severe cases can be life-threatening. Biliary and pancreatic diseases are often difficult to detect early, and treatment is frequently complex.
