Patent number: 10569037Abstract: The system and method for reducing or eliminating obstructive sleep apnea in patients with the use of a nasopharyngeal device. The nasopharyngeal device has at least one cup and a balloon-cuff located at opposing ends of a semi-rigid, solid-walled tube. The balloon-cuff is reversibly inflatable and is located adjacent to the soft palate of a patient when installed. The inflation of the balloon-cuff opens the airway in a patient thereby reducing obstructive sleep apnea. The one or more cups have perforations, holes, slots or the like for increasing air intake. The cups may also contain clips for securing the nasopharyngeal device in place.Type: GrantFiled: February 13, 2015Date of Patent: February 25, 2020Inventor: John M. O'Day

Publication number: 20110152762Abstract: A catheter assembly incorporating a pre-biased indicator, the assembly includes a catheter having a proximal end, a distal end, and catheter walls defining a catheter lumen. The assembly further includes a base located at the proximal end of the catheter, the base defining an opening to the catheter lumen, the base having a first end and a second end. An inflatable balloon having a predetermined fill volume is located at a distal end of the catheter. An inflation valve is located on the base; the inflation valve is in fluid communication with the balloon through an inflation lumen defined by the catheter walls. The pre-biased indicator located on the base in fluid communication with the balloon is configured to provide a discrete visual signal that the pressure of a fluid in the balloon is different from a predetermined level of pressure or the volume of the balloon is different from the predetermined fill volume.Type: ApplicationFiled: December 23, 2009Publication date: June 23, 2011Inventors: Adrienne A.
