Filed:

Jun 16, 2000

Appl. No.:

09/596160

Inventors:

Richard M. Chesbrough - Bloomfield Hills MI
Steven E. Field - Grand Rapids MI
Ryan L. Goosen - Coopersville MI
Jeff Zerfas - Kalamazoo MI
Richard E. Davis - Grand Rapids MI

Assignee:

Inrad, Inc. - Grand Rapids MI

International Classification:

A61B 1734

US Classification:

606185

Abstract:

A biopsy marking apparatus for placing a radiopaque marker at the location of a percutaneous biopsy. The biopsy marking apparatus comprises an introducer in combination with a radiopaque marker. The introducer ejects the radiopaque marker at the location of the biopsy. The introducer is configured to completely eject the radiopaque marker and prevent it from being subsequently drawn into the introducer as the introducer is removed from the biopsied tissue mass. The radiopaque marker has enhanced radiopaque characteristics and enhanced non-migration characteristics.

US Classification:

600435, 600423, 600424, 600427

Abstract:

An apparatus for percutaneously implanting a localization wire into a tissue mass comprises a cannula with a preloaded localization wire. An actuator is provided to effect the relative movement of the cannula and localization wire such that a distal end of the localization wire is exposed to the tissue mass. A method for implanting a localization wire includes inserting a cannula with a preloaded localization wire into a tissue mass and relatively moving the cannula and localization wire to expose a portion of the localization wire to the tissue mass.

International Classification:

A61B 6/00

US Classification:

600431

Abstract:

An apparatus for percutaneously implanting a localization wire into a tissue mass comprises a cannula with a preloaded localization wire having a distal end and at least one anchor. An actuator is in operable communication with the cannula and is configured for operation between a charged condition and a discharged condition to retract the cannula toward a retracted position to expose the distal end and the at least one anchor of the localization wire to the tissue mass, without inducing movement of the localization wire, and with the cannula being removable from the localization wire in its entirety.
