    摘要： An automatic purse string suture device is disclosed that enables a surgeon to install a purse string suture in tissue structures, particularly for sealing the tissue about a cannula. The device is particularly suited for minimally invasive cardiothoracic procedures and is comprised of an applicator having an elongated structure with protrusions extending from the distal edge thereof. Also provided are means for advancing a needle through a passage to pass a suture through tissue that has been conformed to the distal edge of the device. Various means for conforming the tissue to the distal edge are disclosed as are methods for using the device to facilitate cardiothoracic surgery.

    摘要： Exemplary scope systems and methods involve a cannula assembly, a sheath assembly, and a tubing set. A cannula assembly, which may be a non-magnetic scope cap assembly, can include a cannula body, a proximal housing having a strap, an optical window, and a luer for suction or flushing. A cannula body may include a first lumen or scope channel for receiving a visualization device such as an endoscope or laparoscope, a distal end having suction or flushing flush apertures, and a second lumen for providing fluid communication between the apertures and the luer. Exemplary magnetic introducer systems and methods involve a cannula assembly, a sheath assembly, a tubing set. In some cases, the cannula assembly of a magnetic introducer system can be a magnetic scope cap assembly. In addition to cannula and sheath assemblies, magnetic introducer systems can include a magnetic introducer tubing assembly and a stylet assembly.

    摘要： Embodiments of the present invention encompass systems and methods to prevent complications from atrial fibrillation by preventing or reducing the likelihood of blood flow out of the left atrial appendage, to eliminate a possible source of aberrant electrical circuits, or both. Accordingly, techniques are provided for delivering ligature loops or closure means to the left atrial appendage, and to other anatomical structures of a patient which may be desirable in other surgical procedures.

    摘要： An access platform having a first and a second blade interconnected to a spreader member that laterally drives the blades apart or together and a sternal pad interconnected to a blade. The superior blade is pivotally coupled to the spreader member such that it naturally rises as the blades are separated. Alternatively, a vertical displacement member is operably interconnected to a blade and the spreader member and is used to vertically displace the interconnected superior blade and, thus, so increase a surgeon's working space and visual access for the dissection of an internal mammary artery. A tissue retractor is interconnected to the blades to draw the soft tissue around an incision away from the surgeon's working area.
