Marker delivery device with releasable plug
First Claim
1. A marker delivery device for an intracorporeal tissue site, comprising:
- a) an elongated delivery cannula which has a distal end section, an inner lumen and a discharge opening in the distal end section in communication with the inner lumen;
b) at least one elongated fibrous marker body slidably disposed within the inner lumen of the elongated delivery cannula, the at least one elongated fibrous marker body comprising a plurality of bioabsorbable polymeric strands, said strands being compressed to a compressed configuration and bound together in the compressed configuration with a polymer binding agent prior to insertion into the elongated delivery cannula; and
c) a releasable plug disposed within a distal portion of the inner lumen and distal to the at least one elongated fibrous marker body so as to at least partially occlude the discharge opening in the distal end section.

Abstract
A marker delivery device includes an elongated delivery cannula which has a distal end section, an inner lumen and a discharge opening in the distal end section in communication with the inner lumen. At least one elongated fibrous marker body is slidably disposed within the inner lumen of the elongated delivery cannula. The at least one elongated fibrous marker body includes a plurality of bioabsorbable polymeric strands. The strands are compressed to a compressed configuration and bound together in the compressed configuration with a polymer binding agent prior to insertion into the elongated delivery cannula. A releasable plug is disposed within a distal portion of the inner lumen and distal to the at least one elongated fibrous marker body so as to at least partially occlude the discharge opening in the distal end section.

16. A marker delivery device for an intracorporeal tissue site, comprising:
-
a) an elongated delivery cannula which has a distal end section, a discharge opening in the distal end section and an inner lumen extending to and in communication with the discharge opening; b) a releasable plug which has an MRI detectable marker element incorporated therein and which is disposed at least in part within a distal portion of the inner lumen so as to partially occlude the discharge opening in the distal end section; c) a plurality of elongated fibrous marker bodies slidably disposed within the inner lumen of the elongated delivery cannula proximal to the releasable plug, each of the plurality of elongated fibrous marker bodies having a length comprising a plurality of separate bioabsorbable fibers which are compressed and bound together with a synthetic polymer binding agent so as to form the length prior to insertion into the elongated delivery cannula; and d) a plunger slidably disposed within the inner lumen of the elongated delivery cannula with a pusher end proximal to the plurality of elongated fibrous marker bodies in the inner lumen. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A marker delivery device for an intracorporeal site within a patient, comprising:
-
a. an elongated delivery cannula which has a distal end, a discharge opening in the distal end and an inner lumen extending to and in communication with the discharge opening; b. a releasable plug disposed within the inner lumen which partially occludes the discharge opening; c. at least one short term marker disposed within the inner lumen proximal to the releasable plug; and d. a plurality of elongated fibrous markers which are inserted into and slidably disposed within the inner lumen proximal to the at least one short term marker, each of the elongated fibrous markers having a length comprising a plurality of separate bioabsorbable fibers that are compressed and bound together with a polymer binding agent prior to insertion into the inner lumen of the elongated delivery cannula. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)
