Interventional Radiology

Interventional Radiology utilizes imaging to guide targeted treatment of complex diseases to nearly every organ in the body. Interventional radiologists use imaging such as fluoroscopy to guide small catheters to perform procedures that once required open surgeries. Some of the diseases that Interventional Radiologists treat include: gastrointestinal hemorrhage, uterine fibroids, peripheral arterial disease, hepatic and renal malignancies, and enlarged prostates. Microcatheters that are a few millimeters in diameter, are advanced into the smallest arteries to block blood flow (embolization), or deliver medications such as chemotherapy, or scaffold blood vessels using stents to address these conditions. Having the ability to better point and direct these microcatheters around circuitous vessel turns allows physicians potentially better, safer, and faster abilities to treat their patients.


  • Hepatic malignancies

  • Uterine and prostatic artery embolization

  • Gastrointestinal hemorrhage

  • Visceral artery aneurysms

To stop bleeding or abnormal blood flow within an artery, interventional radiologists use a coil embolization technique. A catheter with a metallic coil is inserted into an artery with the occlusion of blood and once reached it is released into the lumen of the vessel. The coil expands and remains firmly in place. Often times more than one coil is needed.

A blood clot will start forming on the coil and the abnormal blood flow will halt creating a permanent seal.

In this swine trial, Bendit is delivering a coil into the right gastric artery. The tip stability and ability to make fine movements allows to control the  placement of the coil and organize it within the vessel for a complete seal.

The microcatheter is an essential tool, used daily, by all interventional radiologists. The Bendit device will move the microcatheter from being a passive Follower to a Leader, one that will function as a direct extension of the physician's hand in the daily care of complex patients.
