12. An implantation system comprising:
-
an implanter including an elongate member that terminates in a opening at a distal end thereof, the implanter being configured for discharging an article through the opening and into a position within a patient; and
an introducer apparatus configured for guiding the implanter through an interior of the introducer apparatus to the position within the patient, the introducer apparatus including a flange, a sleeve having a sidewall that extends longitudinally from the flange and terminates in a distal end portion, and a structure operatively associated with the sleeve, the structure at least partially located within an interior of the introducer apparatus for substantially preventing flow of fluid in at least a first axial direction. - View Dependent Claims (13, 14, 15)

17. A system comprising:
-
means for discharging an article into a position within a patient;
means for guiding the discharging means to the position within the patient, the guiding means including a flange, a sleeve having a sidewall that extends longitudinally from the flange and terminates in a distal end portion, an elongate portion of the discharging means being insertable axially through at least a portion of the guiding means;
means for controlling axial flow of fluid through the guiding means; and
means for securing a handle member to the flange for facilitating insertion of the guiding means into the patient. - View Dependent Claims (18, 19, 20, 21)
