Brief Summary
Microcatheter Facilitating Safer Removal of Blood Clots from Ischemic Stroke Patients
Problem Statement
There are two ways of addressing ischemic stroke: 1. Intravenous TPA can be infused to break up the clot, but it is 75% ineffective and can damage surrounding tissues. 2. Introduce a microcatheter into the clot and aspirate it or get it to “attach” to the catheter, but this only works when large vessels are occluded, which is a small subset of stroke victims.
Technology Description
This invention consists of a microcatheter with two balloons, one distal to the clot and one proximal. The distal end of the catheter is inserted through the clot and then both balloons are inflated. This creates a “sandwich” effect – the proximal balloon cuts off blood flow to the area so the clot has less likelihood of breaking up, and the distal balloon creates a safety stop downstream in case the clot breaks up or comes off the catheter

Concept
Benefit
- Can be used in large and small arteries
- Facilitates safer removal of the clot
