Patent ID: 8075569

Claim:
An improved device for marking a biopsy site, comprising: a needle having a side opening at a first end; and a clip delivery device comprising: a tube having a leading portion with a forward end and a side opening having a center, wherein the forward end of the leading portion of the tube is located at a distance of about 8 mm to 16 mm from the center of the side opening of the tube; a ramp guide surface in the tube; an elongated driver having an end portion located within the tube, the driver being adapted to slide within the tube to a position proximate to the side opening of the tube; and a clip that is at least partially encapsulated in an encasement and is located in the tube at a location that is axially forward of the elongated driver, wherein the needle is a piercing needle having a hollow portion configured for receiving the tube of the clip delivery device at a second end so that during deployment of the encapsulated clip to the biopsy site the needle houses at least a portion of the tube and at least a portion of the driver; wherein upon sliding the end portion of the elongated driver to a position proximate of the side openings of the needle and the tube, the clip is deployed precisely to a central portion of the biopsy site without the need to longitudinally re-position the needle and without having to longitudinally re-position the tube after a biopsy and prior to and/or during deployment.
