Abstract
A biopsy device having a cannula and a cutter is disclosed. The biopsy device includes a guide, such as guide passageway formed in a portion of the biopsy device. The guide passageway assists in positioning a marker deployer in a cutter lumen of the cannula.
Claims14
A biopsy device comprising:
- a cannula having longitudinal axis, a cutter lumen, and a tissue receiving port communicating with the cutter lumen;
- a tissue cutter adapted for translation within the cutter lumen to sever tissue received in the tissue receiving port of the cannula;
- and
- at least one guide disposed proximal of the cannula for positioning a biopsy marker deployer with respect to the cutter lumen.

A biopsy device comprising:
- a body;
- a cannula extending distally from the body, the cannula having longitudinal axis, a cutter lumen, and a tissue receiving port communicating with the cutter lumen;
- a tissue cutter adapted for translation within the cutter lumen to sever tissue received in the tissue receiving port of the cannula;
- and
- at least one guide passageway disposed proximal of the cannula, wherein the guide passageway is angled with respect to the longitudinal axis of the cannula.
2 more elements
A biopsy method comprising the steps of:
- providing a cannula having longitudinal axis, a cutter lumen, and a tissue receiving port communicating with the cutter lumen;
- providing a tissue cutter adapted for translation within the cutter lumen to sever tissue received in the tissue receiving port of the cannula;
- providing a marker deployer adapted to deliver at least one biopsy marker;
- positioning the tissue receiving port of the cannula in tissue to be sampled;
- advancing the tissue cutter distally within the cutter lumen to sever a tissue sample;
