Filed:

Jun 30, 1999

Appl. No.:

09/345668

Inventors:

John S. Daniel - Lawrenceville GA, US
Daniel L. Rogers - Blairsville GA, US

Assignee:

AT&T Intellectual Property I, L.P. - Reno NV

International Classification:

H04B 7/00

US Classification:

370310

Abstract:

A call from a wireline unit to a wireless unit may be made by the wireline unit using an extension of the wireless unit rather than a wireless number of the wireless unit. A table includes an entry for the wireless unit that includes the wireless extension and a corresponding wireless number of the wireless unit. The extension is used to obtain the corresponding wireless number from the entry for the wireless unit in the table. The call then is routed pursuant to the obtained corresponding wireless number. Similarly, the inclusion of wireless units in the communications network allows for calls using extensions between a wireless unit and a wireline unit, between wireless units, and of course, between wireline units.

Appl. No.:

16/360124

Inventors:

- Alpharetta GA, US
Daniel J. Rogers - Roswell GA, US

International Classification:

A61J 15/00

Abstract:

A tubing assembly for use in conjunction with electronic catheter guidance systems is provided and includes a catheter and steering apparatus. The catheter has a proximal end and a distal end that define a lumen therebetween and extends in a longitudinal direction. The steering apparatus includes an electrical connection and a sheath. Further, the sheath includes an electroactive polymer layer, and the sheath's proximal end is coupled to the distal end of the electrical connection, where the steering apparatus is located within the lumen of the catheter. Activation of the electroactive polymer layer results in a change in dimension of the sheath, which initiates a change in a direction in which the catheter travels within a patient's body to assist in accurate placement of the catheter at a desired location. A catheter guidance system and a method for steering a catheter during its placement inside a body are also provided.

International Classification:

Abstract:

Enteral tubes, tube tip detection systems, and methods for detecting tube misplacement are provided. For example, a tube tip detection system comprises an enteral tube having a tip and a first light disposed at the tip that is illuminated as the enteral tube is inserted into a patient to indicate to a user of the system whether the tip is misplaced in the patient's airway. Similarly, enteral tubes are provided that comprise a tip, a length, and a light that is continuously illuminated as the enteral tube is inserted into a patient. Methods for detecting a tube misplacement in a patient's airway include embedding a light into an enteral tube, inserting the enteral tube into the patient through the patient's nose or mouth, and monitoring a location of the light as the enteral tube is inserted into the patient to determine if the tube is traveling into the patient's airway.
