摘要： A device, system, and method for ligating the left atrial appendage without creating pro-arrhythmic tissue. The device may generally include a snare including a thermally transmissive distal portion and a suture including a distal portion, both distal portions having a lasso-shaped configuration that may be positioned proximate the base of the left atrial appendage. Once the distal portions of the snare and the suture are tightened around the base of the left atrial appendage, the thermally transmissive distal portion of the snare may be activated to create an ablation lesion in adjacent left atrial appendage tissue. The lesion may be created with radiofrequency energy or through cryoablation by the circulation of refrigerant within the thermally transmissive distal portion of the snare.

摘要： Medical devices for closing anatomical apertures, such as atrial or ventricular septal defects, are disclosed. The medical devices can include a plug body having a proximal end, a distal end, and a longitudinal axis. The plug body can include an exterior surface, an interior surface defining an interior lumen, and a seal which can be located within the interior lumen. The medical devices can also include at least one arm member extending through the plug body between the exterior surface and the interior surface of the plug body. In certain embodiments, the medical device can include a distal loop and a proximal loop extending through the plug body. In certain embodiments, the proximal loop can be smaller than the distal loop, such that a top end and a bottom end of the proximal loop can fit within a top end and a bottom end of the distal loop.

摘要： Method and systems of determining adequacy of fixation of a medical lead type having a fixation helix are disclosed. The lead of the medical lead type is placed at a desired location within a patient's body and the fixation helix is screwed into tissue at that location. One or more parameters, associated with the lead, are measured at the location. Based upon the measured one or more parameters, determining a number of turns that the helix is embedded into the tissue at the location.
