Benefits of technology

The bioabsorbable element allows for precise localization of the biopsy site, reducing the need for multiple procedures and improving surgical accuracy, while also offering therapeutic options based on biopsy results, and is absorbed within a month, minimizing long-term presence in the body.

Problems solved by technology

For example, during a wide surgical excision for cancer diagnosed by a recent surgical excisional biopsy, surgeons frequently have difficulty in determining the precise relationship of the previously excised tissue to the surgical wound.

Embodiment Construction

[0023]FIG. 2 illustrates a treatment algorithm 2 according to the present invention. As a result of a routine mammography 4, a tumor or other abnormality may be detected as at 6. The typical response will often include additional magnification mammograms or a follow-up mammogram scheduled for some time in the future, such as six months. This is indicated at 8. If the tumor is not palpable, see 9, an image guided needle biopsy by a breast radiologist is typically conducted as at 10. Image guided needle biopsies can be done in a number of ways. Presently, stereotactic (x-ray) and ultrasound guided needle biopsies are commonly used, primarily because of their accuracy, speed and minimal trauma to the patient. Stereotactic needle biopsies typically use a stereotactic table, such as made by Fisher or Lorad, which provides mammography (x-ray) guidance to a biopsy needle assembly. Ultrasound guided biopsies can be conducted with any one of a number of commercially available instruments. An...

Abstract

A biopsy localization device made according to the invention includes an intracorporeal delivery cannula and at least one marker disposed within an inner lumen of the delivery cannula. The marker includes an expandable fibrous body with at least one radiographically detectable marker element. The expandable fibrous body may also be bioabsorbable. Methods of use of the device are also described.
