elongate delivery member. ### Claim 6 (depends on 5) The device of claim 5, further comprising a band, wherein the band substantially surrounds at least a section of the attachment portion of the elongate member and a segment of the proximal portion of the intervention element. ### Claim 7 (depends on 6) The device of claim 6, wherein the band has an inner diameter that is less than a width of the proximal end portion of the intervention element. ### Claim 8 (depends on 6) The device of claim 6, wherein the band does not extend over the tab. ### Claim 9 (depends on 6) The device of claim 6, wherein the band is crimped onto each of the elongate member and the intervention element. ### Claim 10 (depends on 9) The device of claim 9, wherein the band is crimped onto a retention portion of the intervention element, the retention portion being positioned between the hole and a terminal proximal end of the intervention element. ### Claim 11 (depends on 9) The device of claim 9, wherein the proximal end portion of the intervention element comprises a shoulder positioned laterally of the retention portion, the shoulder extending laterally to an extent, measured from the retention portion, that is greater than or equal to a wall thickness the band. ### Claim 12 (depends on 9) The device of claim 9, wherein the retention portion comprises a proximal part and a middle part, the middle part being located between the hole and the proximal part, and the proximal part having a width greater than a width of the middle part. ### Claim 13 (depends on 9) The device of claim 9, wherein the proximal end portion of the interventional element has a top side and a bottom side, the hole extends through the proximal end portion between the top side and the bottom side, and the retention portion extends laterally beyond the attachment portion of the elongate member as viewed from the top. ### Claim 14 (depends on 13) The device of claim 13, wherein, as viewed from the top of the proximal end portion of the intervention element, the retention portion is laterally offset from the attachment portion of elongate member. ### Claim 15 (depends on 14) The device of claim 14, wherein, as viewed from the top of the proximal end portion of the intervention element, the proximal part of the retention portion underlies the attachment portion of elongate member and the middle part of the retention portion does not underlie the attachment portion. ### Claim 16 (depends on 15) The device of claim 15, wherein at least one of the first segment or the second segment of the elongate member has an extending portion that extends into a region that is (i) between the top side and the bottom side of the proximal end portion, and (ii) between the proximal part of the retention portion and the hole, the extending portion and the proximal part being aligned such that a line extending in a proximal-distal direction intersects the extending portion and the proximal part. ### Claim 17 (depends on 6) The device of claim 6, wherein the band is circumferentially continuous. ### Claim 18 (depends on 6) The device of claim 6, wherein the band is radiopaque. ### Claim

attachment portion. ### Claim 26 A method of using a device, the device comprising an intervention element, an elongate manipulation member comprising a distally-located hooked attachment portion extending about a proximal portion of the intervention element, and a joining element substantially permanently attaching the attachment portion to the intervention element, the method comprising: inserting the intervention element into a cerebral blood vessel using the elongate member; manipulating the device to perform a therapy; removing the intervention element from the cerebral blood vessel using the elongate member. ### Claim 27 (depends on 26) The method of claim 26, wherein: the hooked attachment portion comprises a first segment, a second segment, and a bend between the first and second segments; the intervention element comprises a hole through the proximal portion; and the attachment portion extending through the hole at the bend such that the first segment and the second segment are located on different sides of the proximal portion. ### Claim 28 (depends on 26) The method of claim 26, wherein the device is inserted through a microcatheter. ### Claim 29
