  • Patent number: 8523759
    Abstract: Methods for performing minimally invasive heart surgery include accessing a heart of a patient through a first incision on the left thorax of the patient, contacting the heart through the incision with a heart stabilizing device and/or a heart positioning device, introducing at least one coupling device through a second incision on the patient located apart from the first incision, coupling the coupling device with the heart stabilizing device or the heart positioning device, and performing a surgical procedure on the heart. Systems may include a retractor device, a heart stabilizing device, and a coupling device, for enhancing cardiac surgery. Any suitable heart surgery may be performed using methods, devices or systems of the present invention. In one embodiment, a CABG procedure is performed.

  • Publication number: 20090281541
    Abstract: Tissue treatment systems for cardiac surgical procedures can include an ablation and monitoring assembly having a first ablation element, a second ablation element, and a monitoring mechanism. Treatment methods may involve placing an ablation and monitoring assembly of the tissue treatment system at a patient tissue treatment site, applying a first ablative energy to a first tissue location via the first ablation element and a second ablative energy to a second tissue location via the second ablation element, monitoring a condition of the first tissue location with the monitoring mechanism, and modulating application of the first ablative energy to the first tissue location in response to the condition of the first tissue location while maintaining application of the second ablative energy to the second tissue location. Embodiments also include techniques for assessing a conduction delay across a lesion that involve evaluating local activation rates on various sides of a lesion.

  • Publication number: 20090163768
    Abstract: Systems and methods for placing a treatment device within a patient involve advancing a magnetic first introducer into the patient, advancing a magnetic second introducer into the patient, coupling the first introducer with the second introducer via magnetic force, and using the introducer devices to place a treatment device at a desired location within the patient. Optionally, such techniques involve visualization of the introducers or treatment devices during the procedure.

  • Patent number: 6849075
    Abstract: 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.
