Abstract: A method of collection of uncontaminated secretions from the lower respiratory tract of non-intubated patients using a laryngoscope and a translaryngoscopic catheter. After properly positioning the insertion tube of a laryngoscope in the larynx of a patient, the translaryngoscopic catheter is inserted through the instrument channel of the laryngoscope and a sampling element disposed within the lumen of the catheter is exposed to secretions in the lower respiratory tract. The sampling element is retracted and removed from the catheter. Fluid is injected into the tracheobronchial tree through the catheter and aspirated back.
Abstract: A cleaning tool is disclosed for cleaning hard-to-reach and sharply curved passages, particularly those of endoscopes. The tool includes a brush connected to a spring. The spring is connected to a length of flexible tubing. A stiffening member is disposed within the flexible tubing. A fluid passage is provided within the tubing for delivering cleaning fluid or rinsing fluid to the interior of the object being cleaned.
Abstract: The invention provides an improved surgical snare having an operating cable freely rotatable while the handle is maintained steady, having a rotating assembly mounted in the handle so that the axis of rotation of the assembly is essentially coaxial with the longitudinal axis of the handle and having a quick disconnect-connect means for attaching the operating cable to the rotating assembly without external clamping means.
