  • Patent number: 10292812
    Abstract: A method and apparatus for treating a nasal valve condition including surgically forming an access path to create a pocket on a side of the patient's nose. The pocket is positioned between a soft tissue layer and opposing surfaces of upper and lower cartilages of the nose. The pocket spans a junction between the upper and lower cartilages. An implant is placed through the access path into the pocket with a length oriented to span the junction. A delivery system for placement of the implant includes a surgical tool for forming the access path and for delivering the implant into the access path.

  • Patent number: 7703460
    Abstract: An airway condition of a patient's is treated by selecting an implant sized to be implanted within a tongue of the patient. The implant has a tissue-engaging member sized to be implanted within the tongue near a base of the tongue to oppose relative movement between the tissue-engaging member and surrounding tissue of the tongue. The implant further has an elongated tether member with a first end secured to the tissue-engaging member. The implant is placed within the tongue with the tissue-engaging member implanted within tissue of the tongue near the base and with the tether member extending from the first end to a second end near a jaw bone of the patient. The second end of the tether is secured to the jaw bone.

  • Patent number: 7673635
    Abstract: An airway condition of a patient is treated by selecting an implant sized to be implanted within a soft palate of the patient. The implant has a tissue-engaging member sized to be implanted within the soft palate near a trailing end of the soft palate to oppose relative movement between the tissue-engaging member and surrounding tissue of the soft palate. The implant further has an elongated tether member with a first end secured to the tissue-engaging member. The implant is placed within the soft palate with the tissue-engaging member implanted within tissue of the soft palate near the trailing end and with the tether member extending from the first end to a second end near a hard palate of the patient. The second end of the tether is secured to the hard palate.

  • Patent number: 7322356
    Abstract: A method for treating a patient diagnosed with obstructive sleep apnea includes identifying a patient as having sleep apnea susceptible to a first positive airway treatment which is at a first operating pressure level in excess of that which is otherwise tolerable to the patient. The patient is treated with an airway treatment selected to alter a portion of an airway tissue of the patient. The patient is then treated with a second positive airway pressure treatment at a second pressure level, which is below the pressure threshold.

  • Patent number: 7237554
    Abstract: A method and apparatus are disclosed for treating a condition of a patient's airway. The condition is attributed at least in part to a spacing of tissue from opposing surfaces in the airway. In one embodiment, the method and apparatus include placing a tissue contractor within the tissue. The contractor includes a static end and a tissue in-growth engaging end. The static end is secured to a bony structure adjacent to tissue to be contracted. The tissue in-growth engaging end is secured to the tissue and spaced from the bony structure. A spacing between the tissue engaging end and a bony end is contracted in order to place the tissue under tension.
