摘要： An imaging catheter apparatus can include an elongate shaft assembly having a proximal shaft portion and a distal shaft portion. The shaft assembly can be configured to carry an imaging transducer such that the imaging transducer is locatable at or near a distal portion of the elongate shaft assembly. At least one coupler can be attached to the elongate shaft assembly. The at least one coupler configured to permit an end user to at least one of couple or attach at least one of a guidewire or an interventional medical device to the elongate shaft assembly via the at least one coupler. For example, the at least one coupler can include an elastic sleeve. The elastic sleeve can expand to accommodate passage of a guidewire or interventional medical device therethrough. Then, the elastic sleeve can relax or shrink to grip the interventional medical device, such as to secure or stabilize its position with respect to the imaging catheter, such as for performing a medical procedure.

摘要： An esophageal monitoring device includes a camera and, optionally, one or more lights to enable visualization of an interior of a subject's esophagus. Visualization of the interior of the subject's esophagus before and after a left atrial ablation procedure may enable a healthcare provider to determine whether or not the left atrial ablation procedure has damaged the subject's esophagus before the subject experiences any symptoms of such damage. An esophageal monitoring device may also include sensors and/or markers that enable a determination of its location within a subject's esophagus. Such an esophageal monitoring device may be configured for three-dimensional mapping, and enable the generation of an accurate three-dimensional map of the physical relationship between a subject's esophagus and the left atrium of his or her heart. Methods of monitoring a subject's esophagus while a left atrial ablation procedure is being conducted on the subject's hear are also disclosed.

摘要： A surgical system includes at least one light emitter generating light at a first intensity and an array of light sensors including a least one row of light sensors, individual light sensors in the row of light sensors adapted to generate a signal including a non-pulsatile component. The system also includes a controller coupled to the array of light sensors, the controller including an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the row of light sensors, to determine if the non-pulsatile component transitions from a higher magnitude to a lower magnitude and from a lower magnitude to a higher magnitude, and if so, to determine if the first intensity should be changed to a second intensity.

摘要： A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.
