Stylet

Abstract: A uterine sampling instrument has an outer flexible tube 1 and a bendable stylet 20 that is insertable within the outer tube. The length (1) of the outer tube 1 is about 193 mm, the stylet having a rounded tip 22 which projects from the forward, tapered end 3 of the outer tube by about 1 mm. A stop 10 of resilient material is slideable along the outer tube. At its rear end, the outer tube 1 has a hub 5 which can be engaged by a syringe. The stylet 20 also has a hub 24 at its rear end which has a finger grip 26 projecting from one side. In use, the stop 10 is positioned to prevent penetration of the epiblast of the patient, and the forward end 3 of the instrument is inserted through the cervix. Chorionic villi are dislodged from the epiblast by the forward end of the instrument, and the stylet 20 is then removed. The syringe is attached to the hub 5 and suction applied to withdraw chorionic villi for analysis.

Abstract: A biopsy device is disclosed that includes a housing maintaining a stylet and a cannula A control device is operably coupled to operate the stylet and the cannula A handle operates to modify the device from a loading configuration with an expanded profile to a delivery configuration with a reduced profile

Abstract: This study involved 154 anesthetized patients requiring endotracheal intubation, in whom the epiglottis was visible but not lifted, which restricted the view of the glottis. A simple stylet was used to lift the epiglottis, thus improving the view of the glottis with the Glide Scope®, allowing tracheal tubes to be inserted into the patients. The stylet easily resolved the diculty of lifting the epiglottis when using a video laryngoscope, thus facilitating endotracheal intubation in patients undergoing general anesthesia.
