Abstract: A cone-shaped electrode for endocardial use as two insulated conductors which extend transthoracicly to a point exterior of the patient when the electrode is implanted. The connector is coupled to the conductors to provide an assembly which is connected with a pacemaker providing electrical impulses for ventricular stimulation. The pacemaker may be attached to the connector during implantation or immediately thereafter. A cannula-type applicator for the assembly is disclosed.

Abstract: An endotracheal device is provided with a double lumen, one for the passage of oxygen and the other for use in catheterizing or suctioning a patient. The device comprises an endotracheal tube connected to an adaptor which adaptor has connectors for connecting one lumen or passageway to a source of oxygen and for connecting the other lumen or passageway to a source of suction. The device can be used to aspirate and to oxygenate a patient separately or simultaneously.
