A biopsy marker introduction assembly is configured for introduction through a specimen retrieval recess into a probe cutter lumen of a handheld breast biopsy handle. Advancing the cutter causes an extending deployment rod to distally translate within an introducer tube of the introduction assembly, pushing a biopsy marker out of a distal end of the probe at a surgical biopsy site. Thereby, the surgeon is able to position the probe and effect deployment of the marker even if using the other hand to position an imaging device such as an ultrasonic transceiver.

Marker device and method of deploying a cavity marker using a surgical biopsy device

In accordance with the present invention there is provided a biopsy device and method for the collection of at least one tissue sample from a surgical patient. The device includes a frame and an elongated piercing element attached to the distal end of the frame. The piercing element has a distal end, a proximal end and a lumen extending at least partially therethrough. The piercing element has a sharpened member at its distal end for piercing tissue, and a port proximal thereto which exposes the lumen. The device further includes an elongated cutter and tissue remover disposed coaxially and slidably within the lumen of the piercing element for harvesting a tissue mass disposed within the port of the piercing element and depositing the tissue mass proximal to the port for retrieval. Lastly, the device includes a mechanism for automatically axially rotating the piercing element after severing a sample so multiple samples can be harvested about a longitudinal axis of the piercing element without manually rotating the piercing element.

Surgical biopsy device having automatic rotation of the probe for taking multiple samples

In accordance with the present invention, there is provided a surgical device for attaching a first hollow organ to a second hollow organ and creating a passageway therebetween. The device includes a first member comprising a first prong for entering a wall of the first hollow organ and a second prong for entering a wall of the second hollow organ. The prongs each have a proximal end which attaches to the first member and a distal end extending therefrom. The device further includes a second member having a plow for incising at least one of the hollow organs so as to create a passageway between the hollow organs. The second member further includes a plurality of needle paths on either side of the plow for guiding a needle through the walls of the hollow organ on either side of the passageway. The device further includes a means for driving a needle, having a suture attached thereto, so as to attach the hollow organs together. Lastly, the device includes a frame for coupling the first member and the second member together in operational engagement.

An expandable and contractible covering is over the polished rod and the polished rod liner from above the polished rod liner clamp to below the stuffing box. This covering protects the environment in the event of failure of the liner or stuffing box. The covering may be quickly released from a basin below the stuffing box and contracted upward to service the stuffing box. The basin is connected to a special fitting between the stuffing box and pumping tee.
