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.

Claims

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.

7. The method of claim 1, comprising inserting the device to protect against cardio embolic stroke.

6. The method of claim l, the method comprising dilating a valve of the patient with a catheter.

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.
