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.

International Classification:

A61B 6/00
A61B 17/34

US Classification:

600431, 606185

Abstract:

A subcutaneous marking apparatus for placement of an imaging marker at a predetermined site in a tissue mass comprises a handle having a front portion and a rear portion, a cannula, a stylet slidably received within the cannula, a trigger extending from the front portion of the handle and operably engaging the stylet, and an imaging marker disposed within a marker recess in a distal end of the cannula. A user can firmly grasp the marking apparatus in one hand and simultaneously actuate the trigger with a finger or a thumb of the same hand to move the stylet and thereby place the imaging marker at the predetermined site.

International Classification:

A61B 10/00

US Classification:

600567, 600568

Abstract:

A core biopsy device comprises an outer cutting cannula in telescoping register with an inner spoon cannula. The outer cutting cannula is provided at a distal end with an arcuate excising blade that is biased radially inwardly to extend beyond the longitudinal axis of the cannula. The inner spoon cannula terminates at a distal end in an arcuate wall to form a biopsy sample spoon for supporting a biopsy sample thereon. The outer cutting cannula can be rotated relative to the inner spoon cannula so that the excising blade can excise the biopsy sample from the surrounding tissue. After removal of the core biopsy device from the tissue, the outer cutting cannula can be retracted away from the inner spoon cannula to reveal the biopsy sample and enable the sample to be removed from the biopsy device in a relatively undisturbed condition.

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.
