The present invention provides a method of deploying a medical filter within a channel in a patient's body and filter systems which can be used in such a method. Such a filter may include a radially expandable body 52 having an opening 56 in a proximal length thereof. In one method, the filter is urged along a length of the channel with the filter body in a radially reduced configuration.

The proximal length of the body can be drawn into the retrieval catheter, thereby effectively closing the proximally oriented opening within the catheter to retain the particulate material within the enclosure. In a preferred embodiment, the filter body 52 is formed of a porous, resilient fabric having pores therein and the proximal opening 56 is at least five times the size of such pores.
