Abstract:
1. A clip delivery device for mammography comprising: a) an elongated delivery tube having: b) a ramp guide surface that is flat, located in the elongated delivery tube, and inclined so that the ramp guide surface defines a rear end of a leading portion of the elongated delivery tube opening; c) a driver including a portion that slides within the opening of the elongated delivery tube; d) a hub portion affixed, integrated with, or otherwise attached to the elongated delivery tube, the driver, or both; e) a gripping portion, having finger rests attached to the hub portion, that can be used ambidextrously; f) a surface marking pointing towards a direction of the opening in the sidewall of the elongated delivery tube; g) a clip for marking breast tissue of a biopsy site or the site of an aspirated cyst during a radiographic analysis disposed in the delivery tube, wherein the clip has a metal structure consisting essentially of: h) an actuator extending longitudinally from the hub and being attached to the driver so that when an axial force is applied to the actuator, the actuator axially moves the driver and pushes the clip down the elongated delivery tube towards the flat ramp guide surface; and i) a return device for biasing movement of the actuator and the driver so that after deployment, the actuator and the driver will retract to a predetermined position.
