Abstract: A cannula apparatus (100) and method are provided for selective fluid flow in removal and return directions. An outer sheath (102) has proximal (104) and distal (106) outer sheath ends spaced apart by a longitudinal outer sheath body (108) defining an outer sheath lumen (110). At least one fluid removal aperture (112) extends through the outer sheath body. The outer sheath includes a side access aperture (114). An introducer (1534) has proximal (1536) and distal (1538) introducer ends spaced apart by a longitudinal introducer body (1540), which at least partially defines a guidewire channel (1542) longitudinally therealong. The introducer is configured for insertion into the outer sheath lumen with the guidewire channel in fluid communication with the side access aperture. An inner tube (218) has proximal (220) and distal (222) inner tube ends.

Abstract: Systems and methods are provided for predicting the onset of postoperative atrial fibrillation (AF) from electrocardiogram (ECG) data representing a patient. A signal processing component determines parameters representing the activity of the heart of the patient from the ECG data. A feature extraction component calculates a plurality of features useful in predicting postoperative AF from the determined parameters. A classification component determines an AF index for the patient from the calculated plurality of features. The AF index represents the likelihood that the patient will experience AF.

Abstract: The fiberscope (referred to as an “endoscopic stylet” by the inventor) has a largely semi-rigid insertion cord which permits a user to pre-form the endoscopic stylet to follow the anticipated contours of the airway leading to the trachea and to insure that it reliably shepherds the associated endotracheal tube to the intended tracheal position. By visually tracking the progress of the endoscopic stylet through the airway, specifically through the vocal cords and into the trachea, placed at the proper distance above the carina, as permitted by the fiberoptic portions of the endoscopic stylet, proper positioning of the endotracheal tube is virtually assured, and post-intubation verification would be unnecessary in most instances since intubation is itself verification of proper endotracheal tube placement.

Abstract: The invention is of an intubation system which is based on a specially designed fiberscopic instrument of a new design to address the unique requirements for intubation. The fiberscope (referred to as an "endoscopic stylet" by the inventor) has a largely semi-rigid insertion cord which permits a user to pre-form the endoscopic stylet to follow the anticipated contours of the airway leading to the trachea and to insure that it reliably shepherds the associated endotracheal tube to the intended tracheal position. By visually tracking the progress of the endoscopic stylet through the airway, specifically through the vocal cords and into the trachea, placed at the proper distance above the carina, as permitted by the fiberoptic portions of the endoscopic stylet, proper positioning of the endotracheal tube is virtually assured, and post-intubation verification would be unnecessary in most instances since intubation is itself verification of proper endotracheal tube placement.
