Biopsy marker delivery system

a delivery system and biopsy technology, applied in medical science, surgery, vaccination/ovulation diagnostics, etc., can solve the problems of prolonging the duration of the procedure, unneeded additional discomfort for patients, and inability to remove a sufficient amount of lesion from the initial biopsy, so as to prevent further distal movement of the rod

Problems solved by technology

In some cases, however, the physician may be concerned that the initial biopsy failed to remove a sufficient amount of the lesion.
For example, repeated removal of the probe and insertion of a biopsy marking device may cause unneeded additional discomfort to the patient undergoing the procedure; removal of the probe may introduce error in placement of the biopsy marker into the desired location; repeated removal and insertion of each of the devices may prolong the duration of the procedure or spread cancer cells; after the probe removes a tissue sample, it is in the optimal location to deposit a marker; etc.

Abstract

A method for marking a biopsy cavity using a delivery device is provided. The delivery device may include a tube having a lumen and a side exit port communicating with the lumen, a rod slideably located in the lumen of the tube, and a tissue marker removably located at the distal end of the tube. The tissue marker may include a bioabsorbable material and a radiopaque marker. The radiopaque marker may be a metal band, a metal wire, or identified with a number, letter, symbol, or combination thereof.

Description

RELATED APPLICATIONS[0001]This is a continuation of U.S. application Ser. No. 10 / 639,050, filed on Aug. 11, 2003, which is a continuation of U.S. application Ser. No. 09 / 954,792, filed on Sep. 10, 2001, which issued as U.S. Pat. No. 6,605,047, both of which are hereby expressly incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]This invention is directed to delivery devices for delivering subcutaneous cavity marking devices. More particularly, the delivery device may be used with biopsy systems permitting efficient placement of a biopsy marker within a cavity. The device may include an intermediate member which assists in deployment of the marking device. The device may also include a deployment lock to prevent premature deployment of a biopsy marker. The invention may further include the capability to match an orientation of a biopsy probe that has been rotated upon procurement of a biopsy sample.BACKGROUND OF THE INVENTION[0003]Over 1.1 million breast biopsies...
