Abstract
A marker delivery device includes a cannula with a first end, a second end, a marker exit near the second end, a handle into which the cannula extends or to which the cannula is attached, the cannula being capable of receiving a plunger and rod that are operable to deploy a marker from the marker exit, the marker delivery device further including a tapered adaptor portion attached to or surrounding the cannula and abutting the handle. The tapered adaptor portion is configured to engage a plurality of different sleeves for differing biopsy devices. Various aspects offer improved ease of removal from commercially available biopsy devices due to its “pinch release” feature. Various aspects of the device allow use with multiple commercially available biopsy devices so as to ensure proper positioning of the devices for marker deployment.
