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.
Claims17
A method of performing a biopsy, the method comprising the steps of:
- a) positioning a hollow member in a tissue mass;
- b) removing a core tissue sample from the tissue mass through the hollow member;
- c) disposing an insert in the hollow member;
- and
- d) removing a perimeter tissue sample from the tissue mass corresponding to the core tissue sample.
A method of obtaining a perimeter tissue sample from a biopsy site, the method comprising the steps of:
- a) positioning a hollow member at the biopsy site;
- b) disposing an insert in the hollow member to limit an amount of tissue that can be drawn into the hollow member;
- and
- c) removing a perimeter tissue sample from the biopsy site.
A method for obtaining a biopsy sample, the method comprising the steps of:
- positioning a hollow biopsy probe in a tissue mass of a patient;
- displacing a core specimen of tissue into the probe through at least one sample port in the probe;
- severing the core specimen from the tissue mass;
- removing the core tissue specimen from the probe;
- disposing an insert within the probe;
- displacing a perimeter tissue specimen of the tissue mass through the sample port into a specimen chamber, wherein at least a part of the boundary of the specimen chamber is defined by the insert;
- and
- severing the perimeter tissue specimen from the tissue mass.
A method for obtaining a biopsy sample, the method comprising the steps of:
- positioning a hollow biopsy probe in a tissue mass of a patient;
- 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 the hollow biopsy probe to sever the core specimen of tissue from the tissue mass;
- removing the core tissue specimen from the probe;
- disposing an insert within the probe, wherein the insert at least partially defines at least one specimen chamber;
- displacing a perimeter tissue specimen from the tissue mass into the specimen chamber through the sample port in the probe;
- and
- axially translating the cutter to sever the perimeter specimen from the tissue mass.
