Abstract:
1. An apparatus for sequentially inserting wafers into a body space of a patient, the apparatus comprising: a track assembly defining a channel from an introduction end configured to receive wafers, to an opposite discharge end adapted to be positioned within the body space, said channel configured to sequentially receive the plurality of wafers therein and including; a cartridge carrying a plurality of wafers, said cartridge coupled to said track assembly at said wafer channel opening so that a wafer from said plurality of wafers enters said introduction end of said track assembly through said wafer channel opening; an advancement mechanism slidably disposed within said pusher channel of said track assembly and operable on a wafer within said wafer channel to advance the wafer in a first direction along said wafer channel toward said discharge end; means for preventing retrograde movement of a wafer within said wafer channel in a second direction opposite said first direction; an advancement gun supporting said track assembly and having a manually operable trigger operably coupled to said advancement mechanism so that depressing said trigger slides said advancement mechanism in said first direction within said pusher channel; and a pair of locking cams disposed on said cartridge and a pair of latches pivotably mounted to said advancement gun and pivotable to engage said pair of locking cams to removably mount said track assembly, with said cartridge coupled thereto, to said advancement gun.
