Abstract:
1. A combination delivery system and embolic coil, the system comprising: a delivery tube having a distal end, an opposite end, a lumen define axially therethrough; a proximal coil junction disposed between the delivery tube and the embolic coil; the proximal coil junction having a proximal end and an opposite distal end; a detachable wire having a proximal end and an opposite distal end; a terminating feature being disposed on the distal end of the wire; the wire being insertable through the lumen and extending proximally beyond the proximal end of the delivery tube; and at least one stretch resistant member disposed within a coil lumen formed by the embolic coil; a distal end of each of the at least one stretch resistant members being secured to a distal end of the embolic coil, while each of the at least one stretch resistant members is also secured proximate the proximal end of the embolic coil; wherein the proximal coil junction comprises a two piece mating adapter including a first component secured to the distal end of the delivery tube and a second component secured to the proximal end of the embolic coil; the two-piece mating adapter having a first channel defined longitudinally therethrough for receiving therein the terminating feature of the wire and a second channel defined traverse to and intersecting with the first channel; the system further comprises a coil connecting member receivable in the second channel and threadable through the terminating feature of the wire.
