Claim:
An intracorporeal marker delivery device for delivering a plurality of remotely detectable markers to a desired site within a patient's body from which tissue has been removed, comprising: a delivery tube which has a tapered, tissue penetrating distal tip, an inclined discharge orifice in the tapered distal tip and an inner bore extending to the orifice; a plurality of remotely detectable markers which are formed at least in part of bioresorbable material, which partially occlude the bore and are slidably disposed within the inner bore and at least one of which has a permanent radiopaque element disposed therein; an expandable plug, which is formed at least in part of bioresorbable material, which is releasably secured within the inner bore of the delivery tube distal to the at least one marker disposed therein, to retain the plurality of markers within the inner bore, and which has an inclined exposed surface, which is configured to partially occlude the inclined discharge orifice, and which allows passage of at least one marker of the orifice when released from the inner bore; and a plunger slidably disposed within the inner bore proximal to the remotely detectable markers.
