A biopsy device includes an elongated probe having a central longitudinal axis, a proximal end, and a distal end. A tissue penetrating tip includes a proximal base and a sharp distal point. The proximal base is secured to the distal end of the elongated probe. The sharp distal point is distal to the proximal base and is aligned with the central longitudinal axis. The tissue penetrating tip has a plurality of concave surfaces annularly arranged to form at least three adjacent pairs of concave surfaces. Each concave surface of the plurality of concave surfaces extends from the proximal base to the sharp distal point. Each adjacent pair of concave surfaces intersect to form a concave curved cutting edge. Cumulatively, the at least three adjacent pairs of concave surfaces form a plurality of concave curved cutting edges that distally terminate at the sharp distal point.

A control console is disclosed for controlling one or more medical devices. The control console communicates to at least one medical device, and at least one peripheral module associated with the medical device if needed. The control console has a microprocessor for processing data to direct an operation of the medical device.

Universal medical device control console

An apparatus for collecting one or more tissue specimens includes a tissue specimen collector having a cannula receiving opening, a vacuum opening, and an interior. The vacuum opening is on a first axis, and the cannula receiving opening is on a second axis. A removable tissue specimen retaining member is positioned within the interior of the tissue specimen collector. The removable tissue specimen retaining member has a plurality of openings that are interposed between the first axis of the vacuum opening and the second axis of the cannula receiving opening. The removable tissue specimen retaining member is movable along the second axis. An elongated tissue cutting member extends through the cannula receiving opening of the tissue specimen collector to position a proximal end of the elongated cutting member in the interior above the plurality of openings of the removable tissue specimen retaining member.

Biopsy device with fluid delivery to tissue specimens

A system includes a grid-like, breast-receiving pressure plate having a polygonal opening. A prism is configured to match the polygonal opening. The prism includes a first conduit that has a zero first offset from the prism center and a second conduit that has a second offset from the prism center.

Guide block for biopsy or surgical devices

A screen providing a graphical user interface (GUI) for a tissue biopsy system includes a circular area and a plurality of GUI areas of variable size located in the circular area. The plurality of GUI areas includes a first GUI area, a second GUI area, and a third GUI area. The first GUI area is configured to represent a first region of the target site from which at least one tissue specimen has been separated from tissue at the target site by a tissue cutting member. The second GUI area is configured to represent a second region from which the tissue cutting member may separate one or more additional tissue specimens from tissue at the target site. The third GUI area is configured to represent a third region in which the tissue cutting member is deployed to separate a tissue specimen from tissue at the target site.

Graphical user interface for tissue biopsy system

A method for collecting a tissue specimen from a target site within a patient includes rotating an elongated tubular section about a longitudinal axis to provide a desired aperture orientation of a tissue receiving aperture; applying a vacuum within the elongated tubular section to draw tissue at the tissue site through the tissue receiving aperture of the elongated tubular section into the interior thereof; advancing an elongated tissue cutting member longitudinally within the elongated tubular section to cut a tissue specimen from the tissue extending into the elongated tubular section; and applying a vacuum to the proximal end of the elongated tissue cutting member for transporting a cut tissue specimen through the inner lumen of the elongated tissue cutting member to discharge the cut tissue specimen directly from the proximal end of the elongated tissue cutting member into a tissue collection device.

The invention is directed to devices and methods for separating and collecting a tissue specimen from a patient's target site. The device includes a probe member with a penetrating distal tip and a tissue receiving aperture, and a tissue cutting member which is rotatable disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture. The longitudinal edges of the aperture are preferably sharpened to engage the cutting edges of the tissue cutting member. Vacuum may be provided in the inner lumen of the cutting member to transport tissue therethrough. Rotation, rotational oscillation and/or longitudinal reciprocation of the tissue cutting member is effective to separate a tissue specimen from surrounding tissue. An accessing cannula having an tissue receiving aperture may be concentrically disposed within the probe member and about the tissue cutting member. The tissue cutting edge of the tissue cutting member preferably is longitudinally oriented and may have a cutting angle less than 90&#xb0; with respect to the longitudinal axis of the tissue cutting member.

The invention is directed to a system and device for separating and collecting a tissue specimen from a target site within a patient. The device includes a probe component with an elongated tubular section, a penetrating distal tip and a tissue receiving aperture in the distal end of the tubular section proximal to the distal tip, and a tissue cutting member which is slidably disposed within the probe member to cut a tissue specimen drawn into the interior of the device through the aperture by applying a vacuum to the inner lumen of the tissue cutting member. The device also has a driver component to which the probe component is releasably secured. The driver has a drive member for adjusting the orientation of the tubular section and thus the aperture therein and one or more drive members for moving the tissue cutting member within the tubular section to sever a tissue specimen from tissue extending into the interior of the tubular section through the aperture. The motion imparted to the tissue cutter is at least longitudinal and preferably is also oscillation and/or rotational to effectively separate a tissue specimen from tissue extending through the aperture in the tubular section.
