Abstract: An endotracheal tube apparatus with improved deployment and long-term comfort to a patient generally includes a cap mechanism that can direct enriched oxygen towards the patient's lungs while the endotracheal tube apparatus is being inserted in a patient's trachea. Once the endotracheal tube is fully inserted in the trachea, the cap mechanism can be made to redirect the enriched oxygen to inflate an inflatable cuff integrated with the endotracheal tube thereby blocking off the vocal cord region in the patient and stabilizing the endotracheal tube in the trachea. When the cuff is inflated, the cap mechanism can be made to ventilate the patient.

Abstract: Examples of the present disclosure are related to systems and methods for replaceable multiple filter units. More specifically, embodiments describe replaceable filter units that are configured to simultaneously filter fresh and return air.

Abstract: An electrosurgical suction coagulator includes a housing having proximal and distal ends and a substantially malleable elongated tube-like shaft extending longitudinally from a distal end thereof. The elongated tube-like shaft includes a tube-like outer wall having a tube-like dielectric sheath at least partially disposed thereon. A tube-like electrode is disposed coaxially through the tube-like outer wall and is configured to operably couple to a source of electrosurgical energy. A distal end of the tube-like electrode protrudes at least partially from a distal end of the tube-like outer wall and the tube-like electrode has at the distal end thereof at least one aspiration port defined therein. The tube-like electrode is adapted at the proximal end thereof to operably couple to a source of suction. A vacuum space is disposed concentrically between the tube-like electrode and the tube-like outer wall to impede the propagation of thermal energy along the tube-like shaft.

Abstract: An electrosurgical pencil is provided which includes an elongated housing, an electrocautery blade supported within the housing and extending distally from the housing. The electrocautery blade is connected to a source of electrosurgical energy. The pencil also includes at least one activation switch supported on the housing which is configured and adapted to complete a control loop extending from the source of electrosurgical energy. At least one voltage divider network is also supported on the housing and is electrically connected to the source of electrosurgical energy.

Abstract: A method and system of feeding line on a line trimmer. At least some of the illustrative embodiments are line trimmers comprising a motor, a cutting head coupled to the motor (the cutting head having a line inlet along an axis of rotation of the cutting head, and a line outlet in a direction substantially perpendicular to the line inlet, wherein trimmer line extends through the line inlet and then out the line outlet), an elongated shaft that supports the cutting head on a distal end, and a line feed system coupled to the elongated shaft. The line feed system has a first configuration that prevents feeding of the trimmer line toward the line inlet, and a second configuration that allows substantially unimpeded movement of the trimmer line toward the line inlet, the movement caused by centrifugal force on the trimmer line extending from the line outlet of the cutting head.
