Abstract: An excision device including a guide rod assembly and methods of operating the same are disclosed. An excision device includes a housing coupled to a coring cannula, a stylet with a blade, and a guide rod assembly. A hollow central passageway extends through the center of the excision device. The guide rod assembly is coupled to the housing and includes a guide element having first and second ends and comprised of a guide rod and a locking member. The guide rod is slidably disposed within the central passageway. The locking member is fixed to the second end of the guide rod. The guide rod assembly further includes an anchor stabilization rod slidably disposed within the central passageway. A coupling device, a first portion of which is fixed to the guide rod and a second portion fixed to the anchor stabilization rod, couples the anchor stabilization rod to the guide rod.

Abstract: An expanding cannula of an excision device and methods for operating the same are disclosed. An expanding cannula includes a body having first and second ends, the first end coupled to the excision device. The expanding cannula further comprises an expanding coring mechanism coupled to the second end of the body, the mechanism including an annular spring, a plurality of formed fingers extending between the annular spring and the second end of the body, and a retractable flexible blade extending from the second end of the body and over the annular spring. A method for excising tissue using an expanding cannula comprises introducing a bladed stylet coupled to the excision device into a target tissue, retracting the bladed stylet to expose a distal end of an expanding cannula, rotating the expanding cannula using a motor drive to advance the expanding cannula into the target tissue, and collecting a tissue sample.

Abstract: Breast compression devices and methods of operating the same are disclosed. A first breast compression device comprises a back plate, a front paddle comprising two or more fingers, and an adjuster to adjust the space between the back plate and the front paddle. A second breast compression device comprises a back plate, a front paddle comprising two or more fingers, and a bar connecting the back plate and the front paddle. A method for compressing breast tissue with a breast compression device comprises wrapping the breast compression device around the breast tissue from any angle, the breast compression device including a back plate, a front paddle comprising two or more fingers, and a bar connecting the back plate and the front paddle, and adjusting the breast compression device to provide enough compression to render the breast tissue immobile.

Abstract: Incision expanders and methods for operating the same are disclosed. An incision expander includes a housing, an expanding cannula coupled to the housing, a mechanism to expand the expanding cannula coupled to the housing and the expanding cannula, and a removable bladed stylet extending through the center of housing and the expanding cannula. A second incision expander includes a housing, an expanding cannula coupled to the housing, and a tapered stylet extending through the center of housing and the expanding cannula. A method for introducing an excision device through an incision comprises introducing a bladed stylet into a target tissue, the bladed stylet extending through the center of an incision expander, the incision expander comprising a housing and an expanding cannula, actuating a mechanism to expand the expanding cannula, retracting the bladed stylet from the incision expander, and introducing an excision device into the target tissue through the incision expander.

Abstract: A biopsy device includes a coring cannula, a retract stylet, and a localization needle. The coring cannula has a longitudinal axis and a shaft centered on the axis. The stylet has a tip containing at least one blade and a central passage. The localization needle has a channel and is slidably disposed within the central passage. A drive mechanism rotates the cannula and moves the cannula in a direction parallel to the longitudinal axis of the cannula. A guide element has a first end and a second end and is slidably disposed within the channel of the localization needle. The guide element is movable from a first position to a second position within the localization needle.
