US Patent:

50185306, May 28, 1991

Filed:

Jun 15, 1989

Appl. No.:

7/367405

Inventors:

William R. Rank - Gretna LA
Ronald L. Nichols - New Orleans LA
Stephanie G. Schoenberger - New Orleans LA

Assignee:

Research Corporation Technologies, Inc. - Tucson AZ

International Classification:

A61B 1000

US Classification:

128749

Abstract:

A lesion localization and marking wire and needle assembly for marking non-palpable lesions within the body. A marking device having a helically wound coil of wire attached to an end of the shaft which is insertable into the body through a needle or cannula for rotatingly anchoring the marking device into a lesion or tumor is provided. The needle or cannula is inserted into the body with the marking device positioned therein so that when the cannula is positioned proximate to a lesion the shaft of the marker is rotated to advance the marker into the lesion to mark it for subsequent surgical procedures. A second helical wire may be provided on the shaft which cooperates with a wire guide device attached to the needle to enable the physician to determine the depth of the marking device as it anchors into the lesion. In particular, the device is provided for marking for biopsy lesions of the breast.
