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.
