摘要： Intubation apparatus including an airway device, or main tube, which is to be inserted via the patient's mouth and then into the patient's trachea or esophagus. Components within the main tube are selectively operable for establishing either a first airflow path along the length of the main tube or a second airflow path between the proximal end of the main tube and lateral passages provided in the main tube wall, depending on the location of the main tube. An auxiliary tube is secured to the main tube so that the interior of the auxiliary tube communicates with the interior of the main tube at a location downstream of the lateral passages provided in the main tube wall. A suction tube is insertable through the auxiliary tube and into the main tube to a location beyond the distal end of the main tube.

摘要： A collapsible and deployable filter for blocking debris and passing blood in a blood vessel in a patient's body, the filter including; a framework of a flexible material, constructed to have a radially compressed state, in which the framework is radially compressed by radial deforming forces, and a radially expanded state to obdurate an artery; and a flexible filter material secured to said framework and having pores dimensioned to prevent the passage of debris therethrough while allowing the passage of blood. The filter has, in the radially expanded state of the framework, a generally conical or frustoconical form with a large diameter end, a small diameter end opposite to the large diameter end, and a side surface extending between the ends. The filter has an opening that is free of filter material at the small diameter end or in the side surface.
