Patent ID: 8282573

Claim:
A device for delivery of one or more marker bodies through a tubular cutter member of a biopsy device, comprising: a. an elongated marker delivery shaft having an exterior, an inner lumen, a discharge opening in a distal portion of the elongated shaft and a handle on a proximal portion of the elongated shaft; b. at least one marker body which is disposed within the inner lumen of the elongated marker delivery shaft; c. a guide member which is slidably disposed on the exterior of the elongated marker delivery shaft and which has an inner distally oriented, outwardly flared surface configured to guide the distal portion of the elongated marker delivery shaft into a proximal end of the tubular cutter member of the biopsy device and to allow the elongated marker delivery shaft to advance within an inner lumen of the tubular cutter member; d. the handle having a stopping shoulder proximal to the guide member that is configured to stop the proximal end of the tubular cutting member of the biopsy device with respect to the elongated marker delivery shaft; and e. a plunger slidably disposed within the inner lumen of the elongated marker delivery shaft which is long enough to discharge the at least one marker body through the discharge opening in the elongated marker delivery shaft and a tissue receiving aperture in the tubular cutting member when the proximal end of the tubular cutting member engages the stopping shoulder.
