Self cleaning devices, systems and methods of use

摘要

The invention relates to medical devices, systems and methods for preventing the embolic material flowing about a junction of at least one branch blood vessel and another blood vessel from entering the other blood vessel. The device includes a self cleaning flexible filter and a frame. The external surface of the filter is configured to temporarily trap at least some of the embolic material flowing about the junction as a result of the blood inflow though the filter. The filter is also configured to expel the trapped embolic material into the other blood vessel.

主权项

1. A self cleaning device, comprising:
a first flexible filter comprising tapered pores and having a first end, a second end, and a first external surface, the first end configured to reside at or near a junction of at least one branch blood vessel and another blood vessel, and the second end configured to extend at least partially within the other blood vessel; and a first frame positioned at least at the first end of the first filter and configured to hold the first end of the first filter at the junction of the at least one branch blood vessel and the other blood vessel; where the first external surface of the first filter has a first configuration adapted to temporarily trap at least some of the embolic material flowing about the junction of the at least one branch blood vessel and the other blood vessel as a result of blood inflow through the first filter, and a second configuration adapted to expel the trapped embolic material into the other blood vessel.
