摘要： A biopsy device having a cutting element is disclosed. The cutting element includes an inner cannula having a tissue receiving aperture disposed proximate a distal end thereof and an inner lumen. The inner cannula is slidably disposed within the inner lumen of an outer cannula. A vacuum chamber is disposed about at least a portion of the cutting element and is configured to create a vacuum in the cutting element during a biopsy procedure. The inner cannula is advanced distally outwardly and to cause the vacuum to be generated in the vacuum chamber. The vacuum is delivered to the cutting element whereby tissue is drawn into the tissue receiving aperture. The outer cannula is advanced distally outwardly after the inner cannula such that tissue drawn into the tissue cutting aperture is severed.

摘要： A biopsy device is disclosed that comprises a cutting element mounted to a handpiece and a vacuum chamber. The cutting element comprises a stylet assembly and an outer cannula assembly. The stylet assembly includes a stylet that includes an open proximal end and a tissue opening at a distal end thereof. The tissue receiving opening is in communication with a lumen extending through the stylet. The outer cannula assembly includes an outer cannula that is slidably mounted over the stylet and has an open distal end with a cutting edge formed thereon. The vacuum chamber is in communication with the lumen of the stylet. The stylet is selectively advanced distally outwardly with respect to outer cannula to expose the tissue opening to targeted tissue. The outer cannula is selectively advanced over the tissue opening to sever tissue, while vacuum is generated in the vacuum chamber and delivered to the tissue opening through the lumen. The vacuum causes tissue to be drawn into and maintained in the tissue opening while the outer cannula severs tissue to obtain a biopsy core.

摘要： A site marker is provided that includes a generally hollow body defining a cavity. At least one marker element is captured within the cavity but is able to move within the cavity. The capturing prevents migration of the marker within a body. The site marker is formed into a predeployment configuration whereby the site marker is compressed into a predetermined size and shape to as to be readily positionable within a deployment device. The site marker expands from the predeployment position to a post deployment configuration upon insertion into the body.

摘要： A biopsy marker deployment device adapted to selectively deposit a marker in a target location, such as a biopsy site. In one embodiment, the device includes a deployment assembly comprising a cannula adapted to house at least one marker, an outlet aperture defined by a portion of the cannula, and an actuatable pushrod slidably disposed and movable within the cannula. The deployment assembly further comprises a selectively opening outlet door movable between an open position and a closed position. The outlet door is biased in the closed position and at least partially obstructs the aperture in the closed position to prevent a marker from reentering the cannula upon deployment.

摘要： A method of using a surgical system that includes an outer cannula is disclosed. The method includes removably mounting a surgical device to an adapter. The adapter is secured to a stage. The surgical device and adapter is positioned at a predetermined location for inserting the outer cannula toward a target site in a body. Once positioned in the body, the outer cannula is fired to the target site. At least one tissue sample is taken using the surgical device and tissue samples are harvested from the surgical device.
