Patent number: 8979823Abstract: Systems for maintaining a vacuum in a patient's oral cavity comprises an oral device, a vacuum control system, and an assembly including first and second tubes for connecting the vacuum control system to the oral device. The oral device has an internal plenum, and a vacuum is drawn in the plenum by a vacuum pump connected by a first tube of the tubular assembly. The vacuum is maintained by an air source which is connected to the plenum by the second tube of the tubular assembly. By maintaining a constant circulating air bleed through the oral device and the connecting tubes, saliva may be removed from the system and collected in a saliva trap located before the vacuum pump.Type: GrantFiled: February 9, 2011Date of Patent: March 17, 2015Assignee: Apnicure, Inc.Inventors: Jonathan Podmore, Nicholas R. Vitale, John Edwards Crowe, Matthias Vaska

Publication number: 20140360509Abstract: A saliva collector comprises a reservoir and a flow path from an inlet to an outlet on the reservoir. A heating element is disposed along the flow path. The heating element applies heat to force bubbles and foam present in the air aspirated from a patient's oral cavity to collapse. The collapsed bubbles and foam evaporate or drain into the reservoir bottom as liquid saliva.Type: ApplicationFiled: June 6, 2014Publication date: December 11, 2014Inventors: Jonathan L. PODMORE, John Edwards CROWE, Nicholas R. VITALE, Francisco DE LA PAZ, JR., Robert Curtis LOVELACE, Payne McQueen MONTGOMERY, Thomas Duncan KOZLOWSKI

Publication number: 20140053849Abstract: An oral device for temporary placement in a patient's oral cavity includes a base, a tongue-engaging member and a tongue pocket. Partial vacuums are separately drawn through the tongue-engaging member and the tongue pocket in order to advance and control the position of the tongue in order to clear the patient's airway to reduce sleep apnea or treat other conditions.Type: ApplicationFiled: February 5, 2013Publication date: February 27, 2014Applicant: ApniCure, Inc.Inventors: Matthias Vaska, Jonathan L. Podmore, Nicholas R. Vitale, Michael C. Holzbaur, John Edwards Crowe, Sean Christopher Daniel

Patent number: 8656922Abstract: An oral device for improving airway patency includes a tongue constraint and a negative pressure source. The tongue constraint engages the patient's tongue to maintain a clear region below the palate in an oral cavity. By applying a negative pressure in the clear region, an airway behind the soft palate or tongue of the patient can be maintained. The tongue constraint is usually connected to an anchor. The anchor may be held between the patient's teeth or may engage the inferior surface of the palate. Another oral device for improving airway patency includes a lateral tongue structure and a negative pressure source.Type: GrantFiled: February 3, 2012Date of Patent: February 25, 2014Assignee: Apnicure, Inc.Inventors: Matthias Vaska, Jonathan Podmore, John Edwards Crowe, Sean Christopher Daniel

Publication number: 20140014112Abstract: A saliva collector comprises a reservoir, a bubble barrier, and a membrane, where the bubble barrier and membrane are arranged in tandem on a flow path from an inlet to an outlet on the reservoir. Air aspirated from a patient's oral cavity enters the reservoir through the inlet, passes through the bubble barrier to remove foam and bubbles, passes through the membrane to remove entrained liquid saliva, and passes out through the outlet.Type: ApplicationFiled: July 11, 2012Publication date: January 16, 2014Applicant: Apnicure, Inc.Inventors: Nicholas R. Vitale, Kenneth Mejia, Michael R. Holzbaur, John Edwards Crowe, Jonathan L. Podmore

Publication number: 20130263866Abstract: An oral device for improving airway patency comprises a tongue constraint and a negative pressure source. The tongue constraint engages the patient's tongue to maintain a clear region below the palate in an oral cavity and allow an anterior portion of the tongue to rise. By applying a negative pressure in the clear region, an airway behind the soft palate or tongue of the patient can be maintained. The tongue constraint is usually connected to an anchor. The anchor may be held between the patient's teeth or may engage the inferior surface of the palate. Another oral device for improving airway patency comprises a lateral tongue structure and a negative pressure source.Type: ApplicationFiled: June 6, 2013Publication date: October 10, 2013Inventors: Matthias Vaska, Jonathan Podmore, John Edwards Crowe, Sean Christopher Daniel

Publication number: 20130186411Abstract: An oral device for temporary placement in a patient's oral cavity includes upper and lower jaw braces and a tongue-engaging member. The upper and lower jaw braces are connected so that the lower jaw brace is advanced in an anterior direction relative to the upper jaw brace when the upper and lower jaw braces are closed together. A partial vacuum is drawn in the oral cavity and the vacuum and lower jaw displacement together control the position of the tongue in order to clear the patient's airway to reduce sleep apnea or treat other conditions.Type: ApplicationFiled: March 1, 2013Publication date: July 25, 2013Applicant: Apnicure, Inc.Inventors: Matthias Vaska, Jonathan L.
