Interventional Radiology

Interventional Radiology

Interventional Radiology utilizes image-guided procedures to diagnose and treat diseases in nearly every organ system. This enables the doctor to guide small catheters and guidewires, some just a few millimeters in diameter, through blood vessels or other organ pathways to treat many diseases. This treatment is minimally invasive, accompanied by lower patient risks, shorter hospital stays, and decreased total recovery time. Areas of the body that can be treated include the intestine, kidneys, liver, and prostate.

  • Uterine and prostatic artery embolization

  • Gastrointestinal hemorrhage

  • Visceral artery aneurysms

To stop bleeding or abnormal blood flow within an artery, surgeons 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.
