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.

1 . A method for filtering particulate matter from a blood vessel in a patient, the method comprising: 
 inserting a device into the blood vessel, said device including at least: 
 an outer structure capable of insertion into the blood vessel; and  
 an inner filter anchored to said outer structure, said inner filter having a one-way valve though which a medical instrument may be passed.  
   
     
     
         2 . The method of  claim 1  comprising: 
 inserting said device into the blood vessel during an insertion procedure; and    allowing said device to remain in the blood vessel after said insertion procedure is complete.    
     
     
         3 . The method of  claim 1  comprising: 
 inserting an additional filter into said device during a surgical procedure; and    removing said additional filter after said surgical procedure is complete.    
     
     
         4 . The method of  claim 1  comprising treating the patient with a drug for endocarditis.  
     
     
         5 . The method of  claim 1 , the method comprising treating the patient with a drug for blood clots.  
     
     
         6 . The method of claim l, the method comprising dilating a valve of the patient with a catheter.  
     
     
         7 . The method of  claim 1 , comprising inserting the device to protect against cardio embolic stroke.  
     
     
         8 . A method for filtering particulate matter from a blood vessel, the method comprising: 
 providing a device for being inserted into the blood vessel, said device featuring: 
 an outer structure for conforming to a shape of the blood vessel; and  
 an inner filter anchored to said outer structure, said inner filter for filtering the particulate matter, said inner filter having a portion extending beyond said outer structure, said extended portion being at least partially flexible, said inner filter having a one-way valve through which a medical instrument may be passed; and  
   inserting said device into the blood vessel during an insertion procedure; and 
 allowing said device to remain in the blood vessel after said insertion procedure is complete for filtering the particulate matter.  
   
     
     
         9 . The method of  claim 8 , further comprising: 
 inserting an additional filter into said device during a surgical procedure; and    removing said additional filter after said surgical procedure is complete.
