There is provided in accordance with various embodiments of the present invention methods of preventing retention anchors from projecting outside of the native diameter of the frame, thus facilitating recapture of the device. ## Claims ### Claim 1 (canceled) ### Claim 2 A method of deploying an implantable device within a medical patient, comprising: delivering an implant having an expandable frame in a collapsed configuration to a desired location within the medical patient, the expandable frame including a plurality of supports and a plurality of tissue anchors; and expanding the expandable frame from the collapsed configuration to an expanded configuration, wherein the tissue anchors twist to project radially outwardly relative to the supports to engage tissue within the patient. ### Claim 3 (depends on 2) The method of claim 2, wherein the expandable frame is self-expanding. ### Claim 4 (depends on 2) The method of claim 2, wherein the supports and tissue anchors define a planar axis when the expandable frame is in a collapsed configuration, and wherein expanding the expandable frame includes displacing the tissue anchors relative to the planar axis. ### Claim 5 (depends on 2) The method of claim 2, wherein each support defines a longitudinal axis and has a jogged portion, and wherein expanding the expandable frame includes angulating the jogged portion relative to the longitudinal axis. ### Claim 6 (depends on 2) The method of claim 2, further including positioning the expandable frame in at least one of an atrial appendage, a septal defect, a patent foramen ovale, and a patent ductus arteriosus. ### Claim 7 (depends on 2) The method of claim 2, wherein expanding the expandable frame includes bending each support at a bending region, each support having a first aspect ratio, the bending region of each support having a second aspect ratio, the first and second aspect ratios being different. ### Claim 8 (depends on 2) The method of claim 2, wherein twisting the plurality of tissue anchors includes manipulating a turbo element formed on each support. ### Claim 9 A method of capturing an expandable frame disposed within a patient, comprising: engaging an expandable frame disposed within a blood vessel, the expandable frame including a plurality of supports and tissue anchors extending from the supports and penetrating tissue; and collapsing the expandable frame such that the tissue anchors twist inwardly relative to the supports and release the tissue. ### Claim 10 (depends on 9) The method of claim 9, further including at least partially advancing a catheter over the expandable frame to withdraw the expandable frame from within the blood vessel. ### Claim 11 (depends on 10) The method of claim 10, further including withdrawing the expandable frame from within the patient while the expandable frame is positioned in a collapsed configuration within the catheter. ### Claim 12 (depends on 9) The method of claim 9, further including repositioning the expandable frame, while within the patient, after collapsing the expandable frame. ### Claim 13 (depends on 9) The method of claim 9, further including withdrawing the expandable frame from at least one of an atrial appendage, a septal defect, a patent foramen ovale, and a patent ductus arteriosus. ### Claim 14 (depends on 9) The method of claim 9, wherein each support defines a longitudinal axis and has a jogged portion and, and wherein collapsing the expandable frame includes angulating the jogged portion relative to the longitudinal axis. ### Claim 15 (depends on 9) The method of claim 9, wherein collapsing the expandable frame includes bending each support at a bending region, each support having a first aspect ratio, the bending region of each support having a second aspect ratio, the first and second aspect ratios being different. ### Claim 16 (depends on 9) The method of claim 9, wherein collapsing the expandable frame includes manipulating a turbo element formed on each support. ### Claim 17 A method of capturing an expandable frame disposed within a patient, comprising: collapsing the expandable frame from an expanded configuration to a collapsed configuration, the expandable frame defining a native diameter in the collapsed configuration, the expandable frame having a plurality of tissue anchors that extend outwardly from the expandable frame while the expandable frame is positioned in the expanded configuration; moving the tissue anchors relative to the expandable frame downward into and below the native diameter of the expandable frame; and sliding the expandable frame into a lumen defined by a catheter to capture the expandable frame. ### Claim 18 (depends on 17) The method of claim 17, wherein the expandable frame includes a plurality of supports, each support including a jogged portion, and wherein moving the plurality of tissue anchors includes angulating the jogged portion relative to a respective support. ### Claim 19 (depends on 17) The method of claim 17, wherein collapsing the expandable frame includes bending the expandable frame at a bending region of the expandable frame, the expandable frame having a first aspect ratio, the bending region having a second aspect ratio, the first and second aspect ratios being different. ### Claim 20 (depends on 17) The method of claim 17, wherein moving the tissue anchors includes manipulating a turbo element of the expandable frame relative to the tissue anchors. ### Claim 21 (depends on 17) The method of claim 17, further including withdrawing the expandable frame from at least one of an atrial appendage, a septal defect, a patent foramen ovale, and a patent ductus arteriosus.
