Benefits of technology

[0011] A tube guide may be provided that is selectively attachable to a non-working end of a tissue cutting device to facilitate the proper alignment of the

Problems solved by technology

While such a location system is effective, it is obviously intended and designed to be only temporary, and is removed once the surgery or other procedure has been completed.
However, while such staining techniques can be effective, it is difficult to precisely localize the stain.
Also, the stains are difficult to detect fluoroscopically and may not always be permanent.
Each of the above systems and methods for marking a biopsy site has disadvantages associated with effectiveness, accuracy, and invasive surgical techniques.

Embodiment Construction

[0026] An embodiment of a site marker delivery system 10 that may be used in combination with a tissue cutting device for efficiently, accurately and sanitarily depositing a marker at a biopsy site, is disclosed. The marker delivery system 10 includes advantages over conventional delivery devices which are sometimes difficult to use, often result in inaccurate placement of the marker within the biopsy cavity, and allow for relatively large volumes of biological fluids to spill out from the biopsy device onto other equipment, medical professionals, the surrounding work area and floor.

[0027] The site marker delivery system 10 is formed of medical grade materials, for example, stainless steel, plastic and rubber. The site marker delivery system 10 includes universal features that allows the system to be used with a number of tissue cutting devices of different sizes, particularly with regard to an inner diameter of an inner cannula and the length of the cutting element of a particular...

Abstract

A site marker delivery system is provided that may be used in combination with a tissue cutting device for marking a biopsy site. The system includes a tube attached to a hub. A push-rod is slidably disposed within the lumen of the tube. The push-rod is advanced forward through the lumen of the tube causing a marker seated within the tube to be deployed at a biopsy site.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application Ser. No. 60 / 618,868 filed Oct. 14, 2004 which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION [0002] The invention generally relates to a biopsy site marker delivery system that may be used with a biopsy tissue cutting device. More particularly, the invention relates to a biopsy site marker delivery system for non-surgically implanting a site marker at a biopsy. BACKGROUND OF THE INVENTION [0003] In the field of breast cancer, stereotactically guided and percutaneous biopsy procedures have increased in frequency as well as in accuracy as modern imaging techniques allow the physician to locate lesions with ever increasing precision. However, for a given biopsy procedure, a subsequent examination of the biopsy site is very often desirable. [0004] For example, in those cases where the lesion is found to be benign, a follow-up examination of the b...
