Embodiment Construction
[0045] First refer to figure 1 , according to the present invention, a deployment mechanism for an intravascular device comprises an open proximal end 11 (see Figure 11 ), an extended flexible hollow deployment tube 10, and a distal portion terminating in an open distal end 13, and a continuous liquid passage cavity 15 formed between the proximal end and the distal end. A fixation sleeve 12 is secured around the distal portion of the deployment tube 10 and includes a distal extension 17 extending a short distance beyond the distal end 13 of the deployment tube. The deployment mechanism further comprises a coupling element 14 secured to the proximal end (only the proximal end of which is shown) of a filamentary intravascular device 16, which may be, for example, an embolic implant.
[0046] Deployment tube 10 is fabricated from stainless steel and is preferably formed in three sections, each sized to pass through a typical microcatheter. The proximal or main portion 10a is t...
