Abstract: A two piece anastomosis device for attaching two organs together and creating a passage between the organs is disclosed. The anastomosis device has a first tissue clamping ring and a second tissue clamping ring that are brought together to clamp tissue therebetween and cut off the flow of blood to the tissue. The tissue clamping rings are locked together with an adhesive, and over time, causes the clamped tissue to necrose and slough off. The sloughed tissue creates a passageway through the anastomosis device. A method of using the fastener to create a bypass passageway between the stomach and small intestine is disclosed.

Abstract: Disclosed is a minimally invasive surgical instrument that may be used in hand-assisted laparoscopic surgeries. The device is a multifunctional surgical instrument that may be mounted directly on a surgeon's fingertip and inserted through an incision to allow the surgeon to manipulate tissue during a surgical procedure. Versions include marking elements that are actuated to expose marking flowable fluid (e.g., ink pad, marker tip, roller ball). Versions include those that actuate to open an ampoule containing a flowable material (e.g., adhesive) with continued actuation causing dispensing. In addition, two compounds that are mixed at the time of application are provided with a bifurcated ampoule version and a dual cylinder/plunger version.

Abstract: An implantable marker for implantation in tissue of a surgical patient is disclosed. The marker has a base and an elevated bridge. A pair of legs descend from first and second transitions of the bridge. Each leg has a distal tip, a generally straight leg arm adjacent the tip, a camming marker surface between the transitions of the base and the straight leg arm, and a camming marker surface notch. The camming marker surfaces extend outwardly from the straight leg arms of the legs. In its pre-formed configuration, the first and second straight leg arms of the legs of the marker are generally parallel to each other. In its open form configuration, the first and second straight leg arms initially converge towards each other, then diverge into an open form generally taking the shape of the letter “W”. The marker is particularly adapted for fixation in tissue to mark the site of a lesion or other abnormal tissue which may be removed during a biopsy procedure, for example a breast biopsy procedure.

Abstract: An applier for delivering and deploying a biopsy marker to a surgical biopsy site is disclosed. The applier has a ferrule with a forming surface to form the marker on the distal end of a flexible tube. The marker is held at the distal end of the flexible tube in a marker holder. A forming rod slidable in the flexible tube urges the marker into contact with the forming surface of the ferrule for marker formation. The distal end of the flexible tube is delivered through an egress tube, which in turn is delivered through a biopsy cannula adapted for taking the biopsy sample. The egress tube has an alignment hub at its proximal end adapted for orientational alignment with a hub receiver on the biopsy cannula. When properly aligned, the egress opening of the distal end of the egress tube is orientationally aligned with the biopsy port of the biopsy cannula for proper delivery and deployment of the marker.

Abstract: A method for implanting a biopsy marker at a biopsy site within bodily tissue is disclosed. A marker applier is provided which has a marker cannula for receiving the biopsy marker. The marker cannula has a lateral marker window, and the marker is positioned at the window for ejection therefrom. The marker applier also has an ejector rod moveable longitudinally in the marker cannula which, when actuated, forces the ejection of the biopsy marker from the marker cannula through the window and into the tissue. The marker applier is inserted into a biopsy cannula positioned at the biopsy site. The biopsy cannula also has a lateral window, and it is necessary to orient the lateral marker window into alignment with the lateral biopsy window. Upon proper orientation, the ejector rod is actuated, and the biopsy marker is ejected from the marker cannula for implantation in the tissue in a direction substantially perpendicularly to the longitudinal movement of the ejector rod.

Abstract: An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfacing surface applying pressure in a predetermined range wherein one of the interfacing surfaces is positioned on an anvil with a specified preload and spring rate. A second pole is located one of the two interfacing surfaces. In a preferred embodiment, the second pole is located on the same interfacing surface as the first pole and an insulator electrically isolates the two poles. A preferred application of the invention is in a cutting instrument wherein a hemostatic line is formed along a cut line using RF energy.
