The drain is configured to receive fluid when the body is expanded from a first unexpanded condition to a second expanded condition. At least one flowline is connectable to the drain. A screen is positioned over the drain and is configurable to expand from the first unexpanded condition to the second expanded condition. ## Claims ### Claim 1 A system comprising: a body having a plurality of fluid ports positioned radially about the body, the body expandable or inflatable from a first position to a second position such that a diameter of the body at the first position is less than a diameter of the body at the second position, wherein at least one of the plurality of fluid ports is positioned a radial distance from another one of the plurality of fluid ports; a filter positioned about at least one of the plurality of fluid ports to prevent debris from passing into the fluid port. ### Claim 2 (depends on 1) The system according to claim 1, wherein the filter is configured to expand in length or diameter from the first position to the second position. ### Claim 3 (depends on 2) The system according to claim 2 wherein the filter expands at least in part by a first portion of the filter moving with respect to a second portion of the filter. ### Claim 4 (depends on 1) The system according to claim 1 wherein the filter comprises a ball shaped material having gaps between the material sized to receive the fluid and prevent the debris. ### Claim 5 (depends on 3) The system according to claim 3, wherein the filter is located in a track in an outer layer of the body. ### Claim 6 (depends on 1) The system according to claim 1, wherein the filter comprises a bead material covered by an expandable material. ### Claim 7 (depends on 1) The system according to claim 1, further comprising: a base supporting the filter, wherein the base is configured with anti-extrusion fibers. ### Claim 8 (depends on 6) The system according to claim 6, wherein the filter is connected to an outer seal layer of the body. ### Claim 9 (depends on 1) The system according to claim 1, wherein the plurality of ports comprise at least a first port and a second port and further wherein the first port is positioned a radial and longitudinal distance from the second port and further wherein the filter is positioned about the first port and a second filter is positioned about the second port. ### Claim 10 (depends on 9) The system according to claim 9, further comprising a first flow line in the body fluidly connected to a first port and a second flow line in the body fluidly connected to the second port. ### Claim 11 A system comprising: an inflatable packer movable between a first position and a second position, the packer having a greater diameter at the second position than at the first position; a first port in the packer providing fluid communication from an exterior of the packer to an interior of the packer; a filter at least partially covering an exterior surface of the first port, wherein the filter increases in size as the inflatable packer moves from the first position to the second position. ### Claim 12 (depends on 11) The system of claim 11 wherein the filter comprises a material having a first portion overlapping a second portion and further wherein the first section or the second section is movable to increase a size of the filter. ### Claim 13 (depends on 11) The system of claim 11 further comprising a second port positioned a radial distance from the first port, the second port having a filter at least partially covering the second port. ### Claim 14 (depends on 13) The system of claim 13 wherein the filter of the second port is connected to the filter of the first port. ### Claim 15 (depends on 11) The system of claim 11 wherein the filter is secured to an outer layer of the packer. ### Claim 16 (depends on 11) The system of claim 11 wherein the filter comprises a ball material with gaps between individual balls of the ball material, and further wherein the gaps are sized to receive fluid and prevent debris. ### Claim 17 A method, comprising: placing a packer in a downhole environment; expanding the packer in the downhole environment so that an exterior surface of the packer contacts an interior diameter of the downhole environment, wherein during the expanding, a filter covering a drain in the packer expands from a first unexpanded position to a second expanded position; and sampling the fluid through the filter. ### Claim 18 (depends on 17) The method of claim 17, wherein filter comprises a bead material having gaps between the beads sized to receive fluid through the gaps. ### Claim 19 (depends on 18) The method of claim 18, wherein the filter expands by increases in size. ### Claim 20 (depends on 18) The method of claim 18 wherein the filter expands by moving a first portion of the filter with respect to a second portion of the filter.
