Biopsy site marker applier

A system comprising:

• (a) a biopsy device comprising a biopsy needle, wherein the biopsy needle has a distal end comprising a tissue piercing tip, and a tissue receiving aperture placed proximally to the distal end;
• (b) a marker delivery device comprising:
• (i) a marker deployer cannula comprising a distal end, an internal lumen, and a marker exit, wherein the marker exit is spaced proximal to the distal end, wherein the marker exit is in communication with the internal lumen, wherein the marker exit comprises a distal end having a ramped surface;
• (ii) a push rod having a distal end, wherein the push rod is slidably disposed the marker deployer cannula, and
• (iii) a ramped tip comprising a distal tip and a ramp;
• (c) a biopsy site marker, wherein the biopsy site marker has a plurality of edges, wherein the each edge of the plurality of edges is configured to engage at least a portion of an inner diameter of the marker deployer cannula;
• wherein marker delivery device is configured to be insertable into the biopsy device such that the marker exit of the marker delivery device is aligned with the tissue receiving aperture of the biopsy device, wherein the push rod is configured to urge the biopsy site marker up the ramp of the ramped rip and through the tissue receiving aperture of the biopsy device.

A marker delivery device comprising:

• (a) a cannula comprising a distal tip, a side opening and a grip coupled to the cannula, wherein the side opening is positioned proximally relative to the distal tip, wherein the side opening comprises a distal end having a ramp;
• (b) at least one biopsy marker disposed proximally of the side opening within the cannula;
• (c) a push rod, having a distal end and a plunger coupled to the push rod, wherein the push rod is slidably disposed within the cannula proximal to the at least one biopsy marks;
• and
• (d) a ramped endpiece disposed within the distal end of the cannula, wherein the ramped endpiece comprises a distal tip and a compound ramp, wherein at least a portion of the distal tip extends distally from the distal end of the cannula, wherein the compound ramp extends proximally from the distal end of the ramped endpiece, wherein the ramp comprises a first ramped surface adjacent to a second ramped surface, wherein the second ramped surface is configured to align with the ramp of the distal end of the side opening;
• wherein the grip and the plunger are configured to be manipuled by a single hand, wherein the push rod is movable in a distal direction to deploy the at least one biopsy marker from the tube through the side opening.
