Endovascular device for entrapment of participate matter and method for use

Abstract

A method for filtering particulate matter from a blood vessel in a patient, including inserting a device into the blood vessel, the device including at least an outer structure capable of insertion into the blood vessel; and an inner filter anchored to the outer structure, the inner filter having a one-way valve though which a medical instrument may be passed.

AI Technical Summary

Benefits of technology

This patent describes a way to prevent harm from particles like blood clots that could cause damage to important organs in our body. A special type of scaffold called a stent is placed into certain arteries to act as a barrier and catch these particles before they reach their destination. The stent has a unique design and is inserted through a minimally invasive procedure. Overall, this technology helps keep blood vessels safe and healthy.

Problems solved by technology

The technical problem addressed in this patent is the development of a safe and effective device and method to prevent particulate matters like emboli from damaging bodily tissues. Previous attempts had limitations including blocking blood flow, requiring high precision during placement, and being unstable due to the forces of blood pressure and elastic recoil of the arterial walls. There was therefore a need for a new device that could effectively filter emboli without interfering with blood flow or becoming dislodged over time.
