An implant delivery device (100) preferably includes a first shaft (10) having a proximal portion and a distal portion. The first shaft (10) includes an outer surface and an inner surface defining a first lumen along a longitudinal axis. The distal portion includes a tip (18) defining a taper in the distal direction toward the longitudinal axis and terminating at a distal opening. The device (100) also includes a second shaft (19) having a proximal portion and a distal portion and an inner surface defining a second lumen therebetween having a first cross- section. The second shaft is disposed within the first lumen such that the second lumen is generally coaxial with the first lumen to define a chamber. The distal portion of the second shaft terminates in a port (19A) having an opening in communication with the distal opening of the first shaft. The port preferably includes a second cross-section greater than the first cross- section. |
