BIOPSY METHOD
A biopsy marker applier and method are described and illustrated. The biopsy marker applier can include a cannula and at least one marker disposed within the cannula. A member can be positioned on the cannula, such as sliding member disposed to slide along the cannula. The sliding member can be used to control or limit the depth of insertion of the biopsy marker applier in a biopsy device and/or a patient.
1 . A method of delivering a biopsy marker to a biopsy site, the method comprising the steps of:
obtaining a biopsy marker applier comprising at least one biopsy marker;
determining a desired depth of insertion of a portion of the biopsy marker applier within a biopsy device or a patient; and
positioning a movable member along a portion of the biopsy marker applier to a position corresponding to the desired depth of insertion.
2 . The method of claim 1 wherein the step of positioning comprises sliding the movable member along an axial length of a portion of the biopsy marker applier.
3 . The method of claim 1 further comprising the step of inserting a portion of the biopsy marker applier into a biopsy device adapted to obtain a biopsy sample.
4 . The method of claim 1 wherein the step of positioning comprises sliding the movable member distally with respect to a distal tip of the biopsy marker applier.
5 . The method of claim 1 wherein the step of positioning comprises sliding the movable member proximally with respect to a distal tip of the biopsy marker.
6 . The method of claim 1 comprising the step of sliding the movable member to a position designated by an indicator associated with a desired depth of insertion.
7 . A method of delivering a biopsy marker to a biopsy site, the method comprising the steps of:
positioning a biopsy device in a patient;
obtaining a biopsy sample from the patient through an opening in the biopsy device;
determining a desired depth of insertion of a portion of a biopsy marker applier into the biopsy device;
positioning a movable member along a portion of the biopsy marker applier to a position corresponding to the desired depth of insertion;
delivering a biopsy marker from the biopsy marker applier through the opening in the biopsy device.
8 . The method of claim 7 wherein the step of positioning the movable member comprises sliding the movable member along an outer surface of the marker applier.
9 . The method of claim 7 wherein the step of positioning the movable member comprises moving the movable member with respect to an indicator associated with the biopsy marker applier.
10 . A method of delivering a biopsy marker to a biopsy site, the method comprising the steps of:
positioning a movable member along a portion of a biopsy marker applier with respect to at least one of a plurality of indicators associated with the biopsy marker applier;
inserting a portion of the biopsy marker applier distal of the movable member into a biopsy device; and
delivering a biopsy marker from the biopsy marker applier.
