A medical device, for insertion into an anatomical vessel, can include a sheath, a delivery wire, and a frame or vessel-engaging member. The delivery wire can have a first stop, a second stop, and a coupling area between the first and second stops. The coupling area can be disposed within and movable relative to the sheath. The frame or vessel-engaging member can have a matrix of cells, first and second tapered sections, and interlocking members. The interlocking members can be attached to the tapered sections. The interlocking members can be releasably coupled to the delivery wire at the coupling area with the interlocking members surrounded and held in the coupling area by the sheath. The interlocking members can be movable relative to the sheath, and the interlocking members can separate from each other when the interlocking members are positioned distal to the sheath. |

1. A medical device, comprising:
a sheath; a delivery wire having a first stop, a second stop, and a coupling area between the first and second stops, the coupling area disposed within and movable relative to the sheath; and a vessel-engaging member comprising a matrix of cells, first and second tapered sections, and interlocking members, the first and second tapered sections tapering in a proximal direction, the interlocking members attached to the tapered sections, the interlocking members releasably coupled to the delivery wire at the coupling area with the interlocking members surrounded and held in the coupling area by the sheath, the interlocking members movable relative to the sheath, each of the interlocking members comprising a tab having fingers extending therefrom, the fingers of the tabs interlocking with each other at the coupling area, the interlocking members being biased apart such that the interlocking members release from the delivery wire upon moving the sheath, the vessel-engaging member, or both such that the interlocking members are distal to the sheath. |
