Abstract

In the device for administering implants, which comprises an active substance container with injection cannula and plunger, the plunger is arranged in a plunger channel. The plunger channel merges with continuity into the lumen of the cannula. A holder device (5) for the implant (2) is arranged at the lumen-side end of the plunger channel (3).

Claims

1. A device for administering implants, comprising:

an active substance container including an injection cannula having an internal channel, a plunger channel coaxial with the internal channel of the cannula, and a plunger movable within the plunger channel; and

a pair of opposed elastic pins for engaging and preventing inadvertent movement of an implant through the plunger channel, each pin having a rounded end protruding into the plunger channel.

2. A device for administering implants, comprising:

an active substance container including an injection cannula having an internal channel, a plunger channel coaxial with the internal channel of the cannula, and a plunger movable within the plunger channel; and

a pair of opposed spring-loaded pins for engaging and preventing inadvertent movement of an implant through the plunger channel, each pin having a rounded end biased to protrude into the plunger channel.

3. The device of claim 2, wherein the pins are recessible in an opening in a side wall of the container to allow movement of the implant through the plunger channel.

4. The device of claim 2, wherein the pins are movable in a direction perpendicular to a longitudinal axis of the plunger channel.
