Abstract

A system for implanting a solid marker in an animal is provided. The apparatus includes a hollow tube having an entrance and an exit opening. A support is provided for supporting a hollow tube. A plunger is slideably disposed between a first position and a second position within the support. The plunger cooperates with the support and the tube. The plunger engages the marker proximate to the entrance opening of the tube, and ejects the marker through the tube when the plunger is moved from a first position to a second position. The hollow tubes are stored within the support in at least two groups. A gate prevents a tube from the second group from being displaced before the tubes from the first group as depleted.

Claims

1. A marker adapted to be injected subcutaneously into a laboratory animal by an implanting apparatus comprising a glass capsule having therein an electronic transponder, and anti-migration means covering at least a portion of said capsule, said anti-migration means preventing migration of the marker from said laboratory animal.

2. A marker as claimed in claim 1, wherein said anti-migration means includes a layer coating at least a portion of the surface of the capsule.
