Abstract
Methods, devices, systems, and kits for implementing a technique for introducing a marker into a biopsy cavity of a patient in need of a biopsy. The marker is introduced by a biopsy probe assembly, which includes a biopsy needle having a longitudinal axis and an opening facing away from the longitudinal axis and through which a biopsy sample can be taken at a biopsy site. The marker is delivered to the biopsy site through the opening with a biopsy marker deployment device. At least a portion of the biopsy marker deployment device is rotated or is caused to rotate about its longitudinal axis to bar re-entry of the marker into the biopsy needle through the opening. A unique encapsulated marker is disclosed that can be used with the aforementioned method or independent of it.
Claims29
A tissue marker device configured for deployment into a patient in need of a biopsy or other lesion removal, the tissue marker device comprising:
- a) a radiopaque marker;
- and b) an encasement that encapsulates the radiopaque marker, wherein the encasement includes at least one portion configured, upon deployment into a biopsy cavity, to resist penetrating tissue surrounding the biopsy cavity.

A biopsy probe assembly including, a probe body and a biopsy needle connected to the probe body, the biopsy needle including a longitudinal axis and an opening facing away (e.g., sideways) from the longitudinal axis and through which a biopsy sample can be taken;
- and a marker deployment device configured to advance a tissue marker device through the side opening of the biopsy needle;
- and a motor that is adapted to be automatically actuated upon the tissue marker device exiting the opening of the biopsy needle to rotate the biopsy marker deployment device about its longitudinal axis to bar re-entry of the tissue marker device into the biopsy needle through the opening.
(canceled)
A method for introducing a tissue marker device into a biopsy cavity of a patient in need of a biopsy, comprising the steps of:
- a) providing a biopsy probe assembly including a probe body and a biopsy needle connected to the probe body, the biopsy needle including a longitudinal axis and an opening facing away from the longitudinal axis and through which a biopsy sample can be taken;
- b) inserting the biopsy needle into a patient to position it at a biopsy site;
- c) removing a volume of tissue sample from the patient while the biopsy needle is inserted into the patient at the biopsy site thereby defining a biopsy cavity;
- d) delivering the tissue marker device (optionally a radiopaque encapsulated marker) to the biopsy site through the opening with a biopsy marker deployment device;
- and
- e) rotating or causing at least a portion of the biopsy marker deployment device to rotate about its longitudinal axis to bar re-entry of the tissue marker device into the biopsy needle through the opening.
