Claim 10:
11. An apparatus comprising:
a catheter extending from a proximal end to a distal end and configured and arranged for insertion within a tubular organ;
a shaft extending in the catheter from the proximal end to the distal end and being configured and arranged to move within the catheter;
a frame connected to the shaft and configured and arranged with the shaft to retract into the catheter in a collapsed state and to extend out of the catheter in a deployed state; and
a filter having opposing surface areas terminating around a perimeter of the filter, the filter being connected to the frame at the perimeter and configured and arranged with the frame to:
expand with the frame in the deployed state and, in the deployed state, conform one of the opposing surface areas to an inner sidewall of the tubular organ, and
collapse with the frame in the collapsed state; and

wherein the shaft includes an extension arm configured and arranged with the frame and filter to, in the deployed state, engage with respective surfaces of the inner sidewall of the tubular organ in response to a force applied along a first length of the extension arm toward one of the respective surfaces of the inner sidewall and, via the engaging, redirect the applied force in a direction away from the one of the respective surfaces and toward the frame, therein sealing the frame and the perimeter of the filter to the inner sidewall.
