Patent Images
1. A method for obtaining a biopsy sample, the method comprising the steps of:
- positioning a hollow biopsy probe having at least two sample ports in a tissue mass of a patient;
disposing a first insert in the probe to obtain a core tissue sample;
displacing a core specimen of tissue into the probe by displacing the core specimen through at least one sample port in the probe;
axially translating a cutter within die hollow biopsy probe to sever the core specimen of tissue from the tissue mass;
removing the core tissue specimen from the probe;
disposing a second insert within the probe to obtain a perimeter tissue sample, wherein the insert at least partially defines at least one specimen chamber;
rotating the insert to align a specimen chamber with one of the sample ports;
displacing a perimeter tissue specimen from the tissue mass into a specimen chamber through a sample port in the probe; and
axially translating the cutter to sever the perimeter specimen from the tissue mass.

Abstract
A biopsy device having an insert and related method are disclosed. The insert permits a user to obtain a tissue sample surrounding a center core(s) of removed tissue. The additional tissue provides an effective evaluation of whether all the desired tissue has been excised and a determination of whether an acceptable margin of healthy tissue has been removed.

8. A method for obtaining a biopsy sample, the method comprising the steps of:
-
providing a biopsy probe; providing a core insert adapted for obtaining a core tissue sample; providing a perimeter insert adapted for obtaining a perimeter tissue sample; positioning the biopsy probe within a tissue mass; positioning the core insert in the biopsy probe; displacing a core specimen of tissue into the probe; severing at least a portion of the core specimen to provide a core tissue sample; removing the core insert from the probe; inserting the perimeter insert in the biopsy probe after the step of removing the core insert and without removing the biopsy probe from the tissue mass; displacing a perimeter specimen of tissue into the probe; and severing at least a portion of the perimeter speciment to provide a perimeter tissue sample. - View Dependent Claims (9, 10, 11, 12, 13, 14)
