Intubation device and method of use
First Claim
1. An intubation stylet apparatus for use in medical intubation of a patient comprising:
- a stylet wire assembly, including a stylet sheath having a primary lumen and a secondary lumen; and
a stylet cuff installed on the stylet wire assembly so as to be in fluid communication with the secondary lumen.

Abstract
The present invention is a method of performing endotracheal intubation and a new and novel intubation device for performing the method. In an exemplary embodiment of the invention, the intubation device comprises an endotracheal tube having a forward open end and a rearward open end and an inner bore there between. A stylet is telescopingly positioned within the inner bore and extends outwardly from the forward open end and includes a longitudinally extending soft and flexible guide portion. A distal stylet cuff may be inflated to provide a smooth transition from the guide portion to the endotracheal tube, and a proximal unidirectional end cap may engage a proximal connector of the endotracheal tube and cooperate with the cuff to seat the stylet within the endotracheal tube for intubation as a unitary whole.

25. A method of medically intubating a patient comprising the steps of:
-
inserting an intubation stylet within an intubation device;
inflating a stylet cuff installed substantially on the distal end of the intubation stylet so as to seat the intubation stylet within the intubation device and form a tapered transition from a distal flexible guide tip of the intubation stylet to the distal tip of the intubation device; and
passing the intubation stylet and intubation device into the trachea of the patient. - View Dependent Claims (26, 27, 28, 29, 30, 31)

32. A method of medically intubating a patient comprising the steps of:
-
inserting an intubation stylet within an intubation device;
advancing the intubation stylet through the intubation device such that a stylet cuff installed substantially on the distal end of the intubation stylet is temporarily passed out of the distal end of the intubation device;
engaging a unidirectional end cap mounted substantially on the proximal end of the intubation stylet with a connector installed substantially on the proximal end of the intubation device;
retracting a stylet wire assembly of the intubation stylet relative to the unidirectional end cap until the stylet cuff is properly positioned adjacent the intubation device;
inflating the stylet cuff so as to seat the intubation stylet within the intubation device and form a tapered transition from the distal tip of the intubation stylet to the distal tip of the intubation device;
bending the stylet wire assembly of the intubation stylet into a desired configuration, whereby the intubation device conforms to the configuration of the intubation stylet;
passing the intubation stylet and intubation device into the trachea of the patient;
inflating an intubation device cuff so as to seat and substantially seal the intubation device within the trachea;
deflating the stylet cuff; and
withdrawing the intubation stylet proximally by disengaging the unidirectional end cap from the connector.
