摘要： Devices for enhancing minimally invasive cardiac surgery include a visualization device including an inflatable balloon at or near the distal end. Some visualization devices also include one or more lumens for allowing the introduction of one or more devices to a surgical site through the visualization device. Systems of the invention involve a visualization device which has at least one lumen for allowing introduction of an ablation device and/or other devices. A visualization device with an inflatable balloon may be positioned to create a space between a heart and pericardium when the balloon is inflated.

摘要： Systems and methods for forming a lesion on an endocardial tissue of a patient's heart involve placing an ablation assembly inside of the heart and adjacent to the endocardial tissue, and placing a guiding assembly outside of the heart. An ablation assembly includes an ablation element and a first attraction element, and a guiding assembly includes a second attraction element. First and second attraction elements can be attracted via magnetism. Techniques involve forming an ablation on the cardiac tissue of a patient's heart with an ablation element of the ablation assembly. Optionally, techniques may include moving the second attraction element of the guiding assembly relative to the patient's heart, so as to effect a corresponding movement of the ablation element of the ablation assembly.

摘要： Devices and methods provide for ablation of cardiac tissue for treating cardiac arrhythmias such as atrial fibrillation. Although the devices and methods are often be used to ablate epicardial tissue in the vicinity of at least one pulmonary vein, various embodiments may be used to ablate other cardiac tissues in other locations on a heart. Devices generally include at least one tissue contacting member for contacting epicardial tissue and securing the ablation device to the epicardial tissue, and at least one ablation member for ablating the tissue. Various embodiments include features, such as suction apertures, which enable the device to attach to the epicardial surface with sufficient strength to allow the tissue to be stabilized via the device. For example, some embodiments may be used to stabilize a beating heart to enable a beating heart ablation procedure. Many of the devices may be introduced into a patient via minimally invasive introducer devices and the like. Although devices and methods of the invention may be used to ablate epicardial tissue to treat atrial fibrillation, they may also be used in veterinary or research contexts, to treat various heart conditions other than atrial fibrillation and/or to ablate cardiac tissue other than the epicardium.

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： 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.
