1. A device for intravascular intervention, the device comprising:
- an elongate manipulation member comprising a distally-located attachment portion, the attachment portion comprising a first segment, a second segment, and a bend, without any substantial surface crack, located between the first and second segments, the first segment and the second segment extending proximally from the bend, the attachment portion having a maximum lateral dimension that is less than (i) 4 times a maximum cross-sectional dimension of the elongate member along the attachment portion, and (ii) 0.027 inch;
an intervention element comprising a proximal end portion and a hole through the proximal end portion, the attachment portion of the elongate member extending through the hole at the bend such that the first segment and the second segment are located on different sides of the proximal end portion, the intervention element being substantially permanently attached to the elongate manipulation member.

Abstract
A device for intravascular intervention can comprise an intervention element, an elongate manipulation member, and a joining element. The elongate element can comprise a hooked portion extending about a proximal portion of the intervention element. The hooked portion can comprise a bend. The hooked portion can have (i) no substantial surface crack at an interior region of the bend and (ii) a maximum lateral dimension that is less than 0.027 inch. The joining element can substantially permanently attach the hooked portion to the intervention element.
