Implantation system and method for loading an implanter with a prosthesis
First Claim
1. An implanter, comprising:
- a body comprising;
a loading portion having an opening at a first end that is spaced axially apart from a second end by a sidewall portion, the sidewall portion having a radially inner sidewall that tapers from a first diameter at the opening to a second diameter at the second end of the loading portion, the second diameter being less than the first diameter; and
a barrel extending longitudinally from the second end of the loading portion to terminate in an open discharge end, a body lumen extending through the loading portion and through the barrel to provide for fluid communication through the body; and
a plunger dimensioned and configured for movement through at least a substantial portion of the body lumen from the first end of the loading portion to a location adjacent the discharge end of the barrel.

Abstract
An implanter that includes that includes a loading portion having an opening at a first end that is spaced axially apart from a second end by a sidewall portion. The sidewall portion has a radially inner sidewall that tapers from a first diameter at the opening to a second diameter at the second end of the loading portion, the second diameter being less than the first diameter. A barrel extending longitudinally from the second end of the loading portion to terminate in an open discharge end, a body lumen extending through the loading portion and through the barrel to provide for fluid communication through the body. A plunger is dimensioned and configured for movement through at least a substantial portion of the body lumen from the first end of the loading portion to a location adjacent the discharge end of the barrel.

16. An implantation system comprising:
-
a body portion member comprising;
a loading portion having a substantially smooth, radially inner sidewall having a cross sectional configuration that tapers from a first diameter adjacent an opening located at a first end of the loading portion to a smaller second diameter that is spaced axially apart from the first end; and
an elongated barrel that extends from the loading portion to terminate an open discharge end that is spaced apart from the loading portion, the barrel having a lumen that is substantially axially aligned and in fluid communication with the radially inner sidewall of the loading portion, the lumen of the barrel having a cross-sectional dimension that approximates the second diameter of the loading portion;
at least one pusher member having an elongated rod that extends from a first end and terminates in a second end that is spaced longitudinally apart from the first end, the elongated rod of the pusher member having an outer diameter that is between the first diameter and the second diameter of the loading portion; and
a plunger comprising an elongated rod having an outer diameter that is dimensioned and configured for axial movement through the interior sidewall of the loading portion and through at least a substantial portion of the lumen of the barrel. - View Dependent Claims (17, 19, 20)
