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. A method is described for treating cardiac arrhythmia by: verifying at least one location of a patient's cardiac parasympathetic ganglia, advancing at least one treatment member through an incision on the patient into the vicinity of the cardiac parasympathetic ganglia and applying energy to ablate at least one the cardiac parasympathetic ganglia. A combined pacing and ablation probe is described for performing the method.
摘要翻译：装置和方法提供用于治疗心律失常的心脏组织的消融，例如心房颤动。虽然通常使用装置和方法来消融至少一个肺静脉附近的心外膜组织，但是可以使用各种实施例来消融心脏上其他位置的其他心脏组织。装置通常包括用于接触心外膜组织并将消融装置固定到心外膜组织的至少一个组织接触构件以及用于烧蚀组织的至少一个消融构件。各种实施例包括诸如抽吸孔的特征，其使得装置能够以足够的强度附着到心外膜表面，以允许组织通过装置稳定。例如，一些实施例可用于稳定跳动心脏以实现搏动心脏消融手术。可以通过微创导引器装置等将许多装置引入患者体内。尽管本发明的装置和方法可用于消融心外膜组织以治疗房颤，但它们也可用于兽医学或研究领域，以治疗心房颤动以外的各种心脏病和/或除心外膜外的心脏组织。描述了一种通过以下方式来治疗心律失常的方法：通过以下方式来验证患者的心脏副交感神经节的至少一个位置，将至少一个治疗构件通过患者的切口推进到心脏副交感神经节附近并施加能量以消融至少一个心脏副交感神经节。描述了组合的起搏和消融探针以执行该方法。

摘要： A catheter assembly comprises a first branch body having a first axis, a second branch body extending in a non-parallel relationship with respect to the first axis, and at least one electrode carried by the second branch body. In use, the first branch body can be located within a pulmonary vein within the left atrium, while the electrode carried by the second branch body is located in contact with endocardial tissue outside the pulmonary vein. Ablation energy can be transmitted from the electrode to contacted endocardial tissue while the first branch body is located within the pulmonary vein.

摘要： A method for determining a rotor position in a DC motor having a plurality of windings, including a rotor winding and a plurality of stator windings begins with producing a changing current flow in a pulsed winding to induce a response signal in other windings of the motor. The pulsed winding may be the rotor winding or selected ones of the stator windings. If the pulsed winding is the rotor winding, response signals induced in at lest two of the stator windings are analyzed compute the rotor position. If the pulsed winding is the stator winding, response signals induced from pulsing at least two stator windings are sensed in the rotor winding and analyzed compute the rotor position. A system for computing a rotor position may include comparators for comparing induced response signals in stator windings.

摘要： A medical system for performing a tissue ablation procedure comprises a guide sheath and an ablation catheter disposed within an internal lumen of the catheter. The guide sheath has a distal end that includes irrigation exit ports that are configured to perfuse irrigation fluid in a distal direction over the ablation electrode of the catheter when the distal end of the catheter protrudes from the guide sheath. In this manner, the ablation electrode can be advantageously cooled during the tissue ablation process, thereby maximizing the size and depth of the ablation lesion and reducing the duration of the ablation process.
