Abstract
An occlusive implant delivery assembly includes a rapid response decoupling or detachment mechanism that does not effect significant migration of the implant during release. The assembly includes an occlusive implant device, such as an embolic coil, a pusher or device to carry the implant to the selected location, and an expandable coupling-decoupling mechanism for releasing the implant at the selected site. The mechanical construction provides rapid release times. In addition, the releasing mechanism generally operates without exerting any significant force on the implant, thereby avoiding any significant displacement of the implant during release.

21. An occlusive implant delivery assembly, comprising:
-
an occlusive implant; and
an elongated carrier member having a proximal section, a distal section and a lumen extending therethrough, the elongated carrier member engaged with the occlusive implant, the occlusive implant being releasable from the elongated carrier member by hydraulic pressure within the lumen. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. An implant delivery assembly, comprising:
-
an implant;
an elongated carrier member having a proximal section, a distal section, and a lumen extending therethrough, the elongated carrier member engaged with the implant; and
a syringe coupled to the proximal section of the elongated carrier member, the syringe carrying fluid, which, when delivered through the lumen, causes the implant to separate from the carrier member. - View Dependent Claims (30, 31, 32, 33, 34)
